Definitions

  • the invention relates to a drive mechanism for a switch composed of one or more separate switching units, comprising
  • the object of the invention is therefore to provide a drive mechanism in which use can be made of an overturn point mechanism without the disadvantage mentioned in this connection of contact pressure reduction occurring, with the mechanism also being simple in construction.
  • the overturn point mechanism can be moved towards the off position past the overturn point in the drive mechanism according to the invention without the switch switching off, no contact pressure reduction will occur.
  • less mass has to be moved during switching-off, and this advantageously affects the switching-off speed and, consequently, also the breaking capacity of the switch.
  • a further object of the invention is to make the invention suitable in a simple manner for a switch in which the switching units are not mutually connected to one another, except for a switch in which the switching units are connected to one another with a bridge or the like in order to achieve a simultaneous switching of the switching units.
  • the invention can also be made suitable in a simple manner for reducing or even completely preventing undesirable switching phenomena on the load side.
  • the invention is characterized in that at least one of the switching pawls interacts with the associated switching crank in a manner such that the switching unit concerned opens at a predetermined time before the other switching units.
  • the so-called virtual chopping which may occur, in particular, if vacuum switches are used can be completely prevented. If the desired difference in time cannot be achieved as a consequence of the high speeds with which the switching units switch off, the drive mechanism can be adapted for this purpose with the aid of the measures according to Claims 5 and 6.
  • the drive mechanism is characterized in that the switch springs acting on the levers are composed of at least one contact force spring, the contact force spring being fitted on the overrun coupling and being directly coupled to the lever and indirectly, via the overrun coupling, to the coupling rod all this in a manner such that, on the one hand, the coupling rod can be moved directly by the lever to the on position and, on the other hand, can be moved to the off position only after the lever has traversed a certain path.
  • the switch spring interacts in this manner with the lever and coupling rod, it is possible to separate the contacts with a certain starting speed, the so-called "hammer stroke". This provides more certainty that the contacts will be separated from each other even if they are accidentally stuck.
  • the contact force, the stroke and the like, inter alia can be adjusted simply in this manner and are therefore insensitive to manufacturing and assembly tolerances, and also to wear occurring during the service life.
  • the invention furthermore provides the facility of using a compensation spring according to Claims 9, 10 and 11.
  • the switching-on and switching-off speed can be influenced by means of said compensation spring and even if vacuum switches are used, for example, the effect of the atmospheric pressure can be eliminated.
  • the invention also provides for actuating at right angles to said actuating spindle, the drive mechanism being made completely independent of the speed with which the switching units are actuated.
  • the invention has the characteristics according to Claim 12 for this purpose.
  • the object of the invention is furthermore a drive mechanism which can be coupled to, and/or locked with, other switching and/or safety components such as isolation and/or selection switches and/or fuses in a simple but reliable manner and is consequently suitable for use in distribution stations.
  • the subclaims 13 to 16 inclusively reveal the simple manner in which the invention can comply with the requirements for preventing incorrect switching operations and for guaranteeing that maintenance activities can be carried out safely and reliably on a distribution station incorporating the mechanism according to the invention.
  • the interaction with a fuse which is generally present in the case of a distribution station and protects the transformer can be achieved very simply, as Claim 17 indicates.
  • the invention therefore provides a simple but reliable mechanism which can easily be made suitable for a large number of uses.
  • an eccentric bush can be fitted on the pin of a switching crank in order to achieve time-shifted switching of different phases.
  • the switch springs may also be constructed in diverse manners and fitted in diverse places.
  • FIGS 1a and 1b show diagrammatically the principle of the drive mechanism according to the invention, with open switching unit and with closed switching unit respectively.
  • Figure 2 shows a three-dimensional cutaway diagrammatic drawing of a three-phase switch in which a drive mechanism according to the invention is included.
  • Figure 3 shows diagrammatically a locking system which blocks switching-off of two phases until the first phase has actually been switched off.
  • Figure 4 shows a three-phase switch according to Figure 2 provided with further switching and safety components and the associated couplings and locking systems.
  • Figure 5 shows diagrammatically a ring line with distribution stations in which the drive mechanism according to the invention can be used.
  • Figure 6 shows a diagram of a distribution station such as is used with the ring line according to Figure 5, in which switches incorporating the drive mechanism according to the invention have been incorporated.
  • the drive mechanism according to the invention is designed, on the one hand, to meet the requirements imposed by the switching units to be switched and, on the other hand, by the manner of installation in a switch box.
  • the arrangement is at the same time designed also to accommodate further switching and safety components which are generally necessary in the case of use in a distribution station and to be able to house their actuation and locking systems with respect to the switching units in a simple manner and using simple means.
  • FIGS 1a and 1b show diagrammatically the principle of the drive mechanism according to the invention. It relates to the switching unit 106 depicted diagrammatically in the figures as a vacuum switch 102 with contacts 104 and 105.
  • the vacuum housing of the switch is sealed by means of bellows 103 and a leakage-free lead-through of the coupling rod 10 is possible.
  • the main components of the drive mechanism furthermore comprise a lever 7, one end of which (right-hand end) is mounted in B so as to pivot.
  • the lever 7 is linked with the coupling rod 10 of the switching unit 106 by means of a linking overrun coupling 121.
  • the lever 7 is linked by means of a pivoting link 092 to a bush 091 of the spring holder 9, which is mounted around the coupling rod 10 so as to slide.
  • Fitted beneath the spring holder 9 is a switch spring 12 round the coupling rod 10 whose other end rests against a spring cup 101 which is securely attached to the coupling rod 10.
  • the free end of the spring holder bush 091 rests, according to Figure 1a, against a stop 11 which is securely attached to the end of the coupling rod 10. Consequently, the switch spring 12 is therefore linked directly to the lever 7 and indirectly to the coupling rod 10.
  • a switch spring 8 may be used, if desired, to assist in the switching-off and, if vacuum switches are used, to compensate for the atmospheric pressure.
  • Said switch spring 8 can be fitted at any suitable position and may also be constructed, for example, as a tension spring, helical spring and the like.
  • the lever 7 is depicted in the switched-on position of the switching unit 106. As is evident from Figure 1b, the lever 7 has been swung further after the contacts 104 and 105 in the switching unit 106 have touched each other. As a result, the stop 11 is freed from the top of the spring holder bush 091.
  • the force of the switch spring 12 determines the contact pressure so that the switch spring 12 may also be termed the contact-force spring.
  • the lever 7 travels upwards and accelerates under the influence of the force of the switch springs 12 and 8 and strikes the stop 11 at an appreciable velocity, with the result that the contacts 104 and 105 are separated from each other abruptly and rapidly by means of the coupling rod 10, as is desirable not only to switch off rapidly and to increase the breaking capacity as much as possible but also nevertheless to be able to separate accidentally stuck contacts by means of the stroke and to switch off.
  • the actuation of the lever 7 takes place during switching-on with the aid of an overturn point mechanism or snap-through mechanism known per se which operates on the actuating spindle 1.
  • the latter crosses the lever 7 at some distance from the pivot point B thereof.
  • an arm 3 whose end A is acted on by the switch compression spring 5.
  • the switch spring 5 In order to guide the switch spring 5, the latter is mounted on a telescopic rod 4 which is attached to the fixed part of the switch box at the point C so as to swivel.
  • the switching arm 2 with the switching crank 6 at its end which arm is displaced through an angle ⁇ with respect to the arm 3, is attached to the actuating spindle 1. If the actuating spindle 1 rotates, the switching arm 2 with the switching crank 6 at its end therefore swings concomitantly. In doing so, the latter approaches the lever 7 and makes contact with the lever 7 after the point A has passed the overturn point or snap-through point.
  • the switch spring 5 then forces the point A of the arm 3 further in the clockwise direction, as a result of which the switching crank 6 causes the lever 7 to swing downwards to the position of Figure 1b, as a result of which the contacts 104 and 105 first make contact with each other, with the result that the switch is closed, and then the contact-force spring 12 is further compressed until the switch-off pawl 13 locks the end of the lever 7 in that position.
  • the actuating spindle 1 is now rotated anticlockwise, as a result of which the arm 3 again compresses the switch spring 5 until the overturn point or snap-through point is reached and, on rotating further, the switch spring 5 assists and continues the rotation of the actuating spindle until the concomitantly swinging switching crank 6 makes contact with a diagrammatically shown coupling lever 133 at the point 134.
  • lever 133 pivots around the fixed point 135 and its other end 136 forces the switch-off pawl 13 against the force of the spring 131 and in an anticlockwise direction, with the result that the lever 7 is released and, under the influence of the force of the switch springs 12 and 8, abruptly opens the contacts and continues to travel until the state shown in Figure 1a is reached.
  • the diagrammatically shown lever 133-136 is depicted in Figures 1a and 1b alone in order to explain the operation but does not appear in a preferred embodiment according to Figure 2. In the latter case, the switching crank 6 acts directly on the switch-off pawl 13. The action is, however, identical.).
  • the switching unit 106 is switched on and switched off by means of this simple device with a defined speed and in a reproducible manner.
  • the switching-on and switching-off speed and the contact pressure can be adjusted independently of each other by using the switch springs 5, 8 and 12 and can therefore be satisfactorily optimized.
  • the number of moving parts is particularly small and their mass is also small, with the result that a long service life may be expected.
  • the switching-on speed beyond the overturn point is independent of the speed with which the actuating spindle is initially rotated.
  • the switching-off speed is higher because the concomitantly moving mass of the mechanism has been reduced.
  • the contact force continues to be maintained during the first section of the switching-off movement after which the contact separation takes place with a so-called "hammer stroke", which is also advantageous in the case of accidentally stuck contacts.
  • Figure 2 shows, in the form of a cutaway three-dimensional diagram, the structure of a preferred embodiment of the drive mechanism according to the invention as used in a three-phase switch.
  • the mutual position of the different parts is only of importance with a view to a structurally simple switch in which account has already been taken of the facility for interaction with other components.
  • Other arrangements are, of course, possible within the principle.
  • Three levers 7, one for each phase are situated next to one another in one and the same plane. These actuate the coupling rods 10 of the switching units 106 by means of the overrun couplings 121.
  • the latter are shown diagrammatically by R, S and T for the three phases.
  • the levers 7 are mounted so as to swivel by means of their one end at B at fixed points, which are not shown in more detail, of the frame of the switch box.
  • the actuating spindle 1 extends in a plane which is parallel to the levers 7 and perpendicular to the latter and is rotatably supported in the box in diagrammatically shown bearings. Below the actuating spindle 1, sections of the levers 7 are shown in detail, specifically in the form of strips 071 which each contain a window 072.
  • the switch-off pawls 13 which are pressed against the end of the windows 072 facing away from the pivot B by the restoring springs 131 project into said windows.
  • the levers 7 are in the switched-on position and are locked by the switch-off pawls 13.
  • the overrun couplings 121 of the switching units 106 are therefore in the position shown in Figure 1b.
  • a switching crank 6 is attached to the actuating spindle 1 via switching arms 2.
  • said switching cranks 6 are identically oriented.
  • An arm 3 whose end A is acted on by the switch spring 5 of the overturn mechanism or snap-through mechanism is furthermore attached to the actuating spindle 1.
  • the switch spring 5 is mounted around a telescopic rod 4, the one end of which is attached so as to pivot at the point A of the arm 3 and the other end of which is attached so as to pivot at the point C to the frame of the box.
  • the operation and the position correspond to those explained and depicted in Figures 1a and 1b. From Figure 2 it is therefore evident that separate actuating and locking means are used for each switching unit of each phase.
  • actuating spindle having one overturn point mechanism 3, 4, 5 is used for all the phases.
  • the drive mechanism according to the invention can, however, also be satisfactorily used for a switch in which the phases are rigidly coupled to one another. In that case, the actuating and locking means are of shared construction.
  • the drive can be achieved by a separate drive spindle.
  • the link between the drive spindle 21 and the actuating spindle 1 is formed, according to a preferred embodiment, by a very simple overrun coupling 22, 23.
  • the drive spindle 21 crosses the actuating spindle 1 at right angles and at some distance, and is furthermore mounted in the frame of the box. In the region near the point where the drive spindle 21 and the actuating spindle 1 cross each other, the drive spindle 21 is provided with a drive crank 22 having a pin.
  • a transmission crank 23 which is also mounted on the actuating spindle 1.
  • Said transmission crank 23 is provided with two crank pins which are staggered through a peripheral angle with respect to each other.
  • Said peripheral angle is determined by the angle through which the actuating spindle 1 rotates after the overturn point has been passed and should be at least as large.
  • Said peripheral angle should also be limited in such a manner that, in the rest state, one of the crank pins of the transmission crank 23 can be driven by the pin of the drive crank 22.
  • the switching cranks 6 of the actuating spindle 1 are attached to the actuating spindle 1 in a manner such that they make contact with the levers 7 at the instant when the overturn point has been passed.
  • the drive crank pin 22 will move the uppermost transmission crank pin 23 of the actuating spindle 1 upwards until the switch spring 5 causes the actuating spindle 1 to continue to rotate rapidly after the snap-through point has been traversed, as a result of which the drive crank pin 22 enters freely into the space between the two transmission crank pins 23.
  • the transmission 22, 23 therefore acts as an overrun coupling.
  • Figure 3 shows an example of a manner in which a reproducible time difference can be achieved by mechanical means in the switching off of different phases, with a lock to influence the time difference.
  • the three phases with which the components concerned are associated are indicated as an example by the indices R, S and T.
  • the lever 7 (R) is provided with an additional opening 073 through which the one leg of a further locking pawl 13A (R) is fitted.
  • Said locking pawl 13A (R) is essentially L-shaped and is attached so as to pivot in a fixed point E in the intersection of the two legs.
  • a tension spring or the like 131A functions in a manner such that the locking pawl 13A (R) tends always to rotate in the anticlockwise direction. In the state shown, this is prevented because the other leg is resting against a stop F. If the switch is now switched off, the switching crank 2, 6 will run up against the switch-off pawl 13 (R) and release the lock of the switching unit (R) concerned.
  • the switch-off pawls 13 (S, T), which are shown by broken lines, of the other switching units (S, T) have not yet been actuated by the switching cranks 2, 6 concerned because the latter are displaced at an angle a small amount in the counterclockwise direction (S, T).
  • the actuating spindle 1 with the switching cranks 2, 6 (S, T) is retained in said state because the switching crank 2, 6 (R) is up against the other leg of the switch-off pawl 13A (R) which is blocked against rotating clockwise by the lever 7 (R) through which the one leg of the switch-off pawl 13A (R) is fitted.
  • the drive spindle 21 is rotated by means of a key, which is not shown, which can be fitted on the end 211 of the drive spindle 21 at the actuating side.
  • FIG. 5 shows diagrammatically a ring line R which is fed in a known manner from the mains N.
  • the ring line accommodates a number of distribution stations 40 which each feed a number of loads V via a linking transformer T.
  • Each distribution station 40 has two cable connections K of the ring line and a transformer connection T.
  • FIG 6 shows diagrammatically the interior of a distribution station 40 in which use can advantageously be made of the drive mechanism according to the invention.
  • This shows three fields, specifically the two cable fields K and the transformer field T.
  • Each field is provided with a switching unit 106 which is actuated by a drive mechanism 071.
  • the three fields are linked to one another by a rail system 39.
  • Accommodated in each field between the rail system and the switching unit is a selection switch 261 which can connect the field either to the rail system or to earth.
  • the drive mechanism of the selection switch is shown diagrammatically by 29, 30, 27.
  • mutual locks are necessary for safe operation between the selection switch and the switching unit, which locks are indicated diagrammatically by 25, 31, 35.
  • FIG 4 together with Figure 2, shows the mechanism according to the invention in which the switch for use in a distribution station is furthermore provided with a selection switch 261 for each switching unit 106 of the phases R, S and T.
  • Said selection switches are preferably fitted in a row parallel to and behind that in which the switching units are situated.
  • the drive pins 26 are depicted, which drive pins are coupled to one another by means of a bridge 27 and are therefore actuated simultaneously according to this example.
  • a further drive spindle 29 is mounted in the frame of the box, which drive spindle runs parallel to the drive spindle 21 of the switching units.
  • the crank pin of the selection switches can be moved up and down by rotating the drive spindle 29 until specified end positions are reached in which, for example, a connection is made to the rail system or to earth.
  • the drive spindle 29 is provided, at the actuating side of the switch, with an end 291 which is suitable for engaging the separate actuating key.
  • a locking slider 31 can be slid to and fro in guides, which are not shown, parallel to the actuating spindle 1.
  • the locking slider 31 is provided with a number of upwardly open slots 311 situated at a distance from one another such that, in the case of a three-phase switch box, the three levers 7 can drop simultaneously into the slots 311 if they are in the switched-on position as shown in Figures 2 and 4.
  • the locking slider is constructed in a manner such that it can only be slid to and fro if the levers 7 are in the uppermost, switched-off position because they are then situated outside the top of the slots 311.
  • the locking slider is slid as a result of the fact that a crank pin 33 can be displaced in an additional slot 312 provided in the locking slider, which crank pin is attached to the end of a spindle 32 on which, for example, a round selection disc 25 having a handle 251 is mounted.
  • the spindle 32 runs parallel to the two drive spindles 21 and 29.
  • the crank pin 33 is moved from the position drawn to the position shown by broken lines or vice versa.
  • the locking slider 31 is first moved to the left in the figure and then moved in turn to the right to the same position.
  • this sliding of the locking slider 31, and therefore the rotation of the selection disc 25, can only be carried out if the levers 7 are in the switched-off position.
  • the selection disc 25 is completely solid. It consequently covers in each case one of the actuating ends 211 and 291 of the drive spindles 21 and 29. In the position drawn, however, one actuating end 211 of the drive spindle 21 is accessible so that the actuating key can be fitted on the drive spindle through the actuating opening 24.
  • the locking slider 31 is in the position depicted so that the actuating spindle 1 can be rotated by means of the drive spindle 21 in order to switch the switching units on or off.
  • the locking slider 31 can be slid by rotating the selection disc 25 so that the actuating opening 24 can then be rotated in front of the actuating end 291 of the drive spindle 29 of the selection switch 261.
  • the selection switches can be switched to earth or rail with the aid of the actuating key on the drive spindle 29. It is therefore impossible to actuate the selection switches with the locking slider 31 with the switching units switched on.
  • rotating selection disc described may also be replaced, for example, by a selection disc making translation movement provided only the one or the other of the drive spindles 21 and 29 is made accessible.
  • the drive spindle 29 of the selection switches may furthermore simply be provided with a locking disc 35 mounted thereon which is provided with at least one slot 351.
  • a locking pawl 34 Fitted on the locking slider 31 is a locking pawl 34 which is able to drop into the slot 351 of the locking disc 25 if the drive spindle 29, and therefore the selection switches, are in the correct and desired switching state. It is only then that the locking slider 31 can be moved because the locking pawl 34 is able to penetrate into the slot with the result that the selection disc 25 can be turned back to the position depicted in order to actuate the drive spindle 21 of the load switches.
  • the selection disc 25 can only then be turned to the depicted position in which the drive spindle 21 of the switching units can be actuated. Under certain circumstances it may also be desirable to be able to rotate the selection disc into both switching positions of the selection switches. In that case the two slots 351 are necessary in the locking disc 35. It is, of course, quite possible to conceive other embodiments which are not shown and which are able to achieve the same result without, however, departing from the scope of the invention.
  • the invention provides for the further combination of the drive mechanism with a safety component.
  • This relates to the automatic switching-off of the switch in the event of the fuse blowing if a fuse is used in a transformer field of a distribution station. In that case, a fuse is used in which a striker pin emerges from the fuse 361 in the event of its blowing. In such a case, after the switch has been switched on by means of the drive spindle 21, it is turned back again past the snap-through point. Normally, all the switching units would immediately be switched off under the influence of the switch spring 5.
  • an additional blocking strip 38 is fitted on the actuating spindle 1, which blocking strip 38 assumes a position with respect to the actuating spindle 1 and with respect to a locking lever 37 which is such that the blocking strip 38 comes to rest against the locking lever 37 (as depicted by the broken lines in Figure 4) if the actuating spindle 1 is turned in this manner through the snap-through point.
  • the switching cranks 6 are already swivelled aside under these circumstances to such an extent that they are no longer in contact with the levers 7, the latter are still retained in the switched-on position by means of the switch-off pawls 13.
  • the mechanism according to the invention complies with the following objectives:
