Definitions

the invention relates to an electrical switching device with a contact drive, in particular an electromagnetic switching device with a magnetic drive with magnetic core and armature and with at least one vacuum interrupter with a fixed contact and one with a lifting rod in direct linear Operationally connected movable contact and one with the lifting rod and the armature operatively connected rocker switch to implement the Drive movement in a switching movement of the movable contact, wherein the lifting rod at one end with the one carrying the movable contact Contact carrier is firmly connected and the contact carrier on the output side of the Vacuum switching tube in a tube bearing with respect to the longitudinal axis of the lifting rod is slidably mounted.
the invention has for its object, even with a non-linear control and attack of the rocker switch on the in linear operative connection the movable switching contact standing rod an improved guidance the same to achieve a non-centered encounter of the To avoid contacts.
an opportunity is to be created the stroke of the lifting rod when opening the switch contacts in a maximum limit extended position.
the invention solves this problem by design according to the invention of a generic switching device in such a way that the lifting rod their other end in a second axle guide bearing with respect to their Longitudinal axis is slidably mounted and the operative connection of the Shift rocker on the lifting rod between the tube bearing and the axle guide bearing is arranged.
the movable contact of the vacuum interrupter by direct connection of the lifting rod only in the tube bearing of the vacuum interrupter, but also behind the actuation point or point of application of the rocker switch on the lifting rod Transfer of the switching movement of the armature.
a contact pressure spring is used to control the rocker switch on the lifting rod provided coaxial to the lifting rod between the two bearings, which is supported on the side facing the tube bearing on the lifting rod and on the side facing the axle guide bearing at the fork ends supports the rocker switch, so that a movement of the rocker switch over the contact pressure spring on the lifting rod and the connected to it moving contact is transmitted.
a buffer is movably arranged on the lifting rod.
This buffer is preferably in three parts and consists of one on the rocker switch or their fork ends adjacent disc and a conical pan and Conical disc, which on the lock nut or round nut of the lifting rod in Bear the axle guide bearing.
the axial guidance of the lifting rod in the Additional axle guide bearings are used, for example, at the end the lifting rod firmly attached round nut as a plain bearing, the for example, is also attached as a lock nut. Because the rocker switch cannot move the lifting rod completely axially due to its swiveling movement, however, this is due to the additional second axial guidance of the lifting rod balanced in the axle guide bearing by means of the round nut or the axial guidance improved.
the axle guide bearing is open its inner end face adjacent to the end of the lifting rod a stop surface for the round nut to limit the maximum permissible Opening path of the lifting rod is formed when the switch contacts are opened.
the contact pressure spring takes off the electromechanical forces and limits the opening path of the Lifting rod.
this stop is used as an emergency stop on the axle guide bearing, by striking the round nut here. This can prevent the maximum compatible opening travel of the metal bellows of the vacuum interrupter is not exceeded.
the round nut slides in the axle bearing guide in the axial direction of the lifting rod under the action of the actuation attack of the rocker switch, one some friction occurs. For this reason, the round nut is preferred made of a good sliding material.
the axle guide bearing can in the area of the side housing walls Switching device, for example, by means of perpendicular to the longitudinal axis of the axle guide bearing and the lifting rod on both sides through the axle guide bearing in the Housing guided screws are attached.
FIG. 1 those of the vacuum switching device that are essentially involved here Organs in cross section AA shown in FIG. 4.
the anchor 10 is on the anchor receptacle 11 attached and on the rocker switch 2 with an intermediate layer the damping bearing 12 is fixed by means of the bolt 13, on the one end of the rocker switch 2 trained rocker bearing 21.
Die Switch rocker 2 is in turn in the rail support housing 4 or not Drive housing of the vacuum switching device shown further pivotable stored.
the vacuum interrupter 45 In the upper area of the rail support housing 4 is the vacuum interrupter 45 arranged, which carries the fixed contact 41 at one end Fixed contact carrier 40, which by means of screw 17 on the terminal lug 16 is fixed and is fixed in the rail support housing 4.
the switching tube also includes the movable contact carrier 43 the movable contact 44, whose movement in the direction of arrow P2, P2 'by means of of the metal bellows 46 sealed against the vacuum interrupter 45 is.
the vacuum interrupter 45 On the output side, the vacuum interrupter 45 has the tube bearing 47, in that of the contact carrier 43 in the slide bearing 47a in the switching movement direction is slidably mounted. In a linear direct operative connection with the movable contact carrier 43 and thus the movable contact 44 the lifting rod 5 attached to the end of the contact carrier 43, which in this Fastening area is also guided through the tube bearing 47.
the end of the lifting rod 5 is guided axially in the axle guide bearing 6 the axle guide bearing 6 in the area of the side wall of the rail support housing 4 arranged and there by means of screws 53 which are perpendicular to Longitudinal axis X of the lifting rod extend, are arranged.
Strand 14 is attached directly to the end of the movable contact carrier 43 and fixed on the other side by means of a hexagon nut 54.
the rocker switch 2 engages with its fork ends 22a, 22b, see also Fig. 4, on both sides of the lifting rod 5 between the two bearings 47 and 6.
a contact pressure spring 7 is coaxial with Lift rod arranged, which at one end on the lock nut 55 over a spring plate 56 with internal thread arranged there abuts and is supported and is fixed, while at the other end the contact pressure spring 7th one longitudinally displaceable in both directions along the axis X spring plate with extension 58, on which the rocker switch with its fork ends 22a, 22b attacks.
the axle guide bearing 6 for the free end of the lifting rod 5 is in the figures 3a, 3b shown in more detail. It has a bearing bore 61 with an outlet opening 62 at the front end, which is smaller than the bearing bore 61, so that a contact surface 63 is formed on the inside of the end face is. 3b, the through holes 64, 65 are the Axle bearing guide for fastening the same to the rail support housing 4 can be seen.
a two-hole round nut 51 fastened from a slidable material.
the sliding surface and guide surface forming round nut at the extreme end of the lifting rod and the Hexagon nut 52 is then arranged on the inside.
the two-hole round nut 51 is used to guide the lifting rod in the execution bearing 6, while the hexagon nut 52 is used for stroke adjustment and by means of the round nut is countered.
the rocker switch 2 lies with its fork ends 22a, 22b not directly on the axle guide bearing 6, but it is a movable one Multi-part buffer arranged longitudinally displaceably on the lifting rod 5 provided between axle guide bearing 6 and rocker switch 2.
This buffer is composed of a disk 57, which is directly on the fork ends of the rocker switch abuts, and a conical socket 59b and conical disk 59a together.
This Buffer also serves to compensate for the non-linear actuation attack Switch rocker on the lifting rod via the contact pressure spring and the spring plate 56 especially when returning the lifting rod in the direction of arrow P2 ' when opening the switch contacts and swiveling the rocker switch back into the 1 shown starting position.
the movable contact 4, the movable Contact carrier 43, the strand 14, the nuts 54, 55, the lifting rod 5 and the two-hole round nut 51 and the hexagon nut 52 are rigid with one another connected and overall in the direction of arrow P2 to close the contacts and in the direction of arrow P2 'to open the switching contacts in the tube bearing 47 and the axle guide bearing 6 slidably mounted.
the closing movement is shown schematically in FIG. 5.
the opening movement takes place in the opposite direction, i.e. the anchor moves in the direction of the arrow P3 ', the rocker moves back due to the spring force the contact pressure spring 7 in the starting position, the lifting rod 5 with the movable contact 44 is moved back into the open position becomes.
