Definitions

  • the invention relates to a locking device according to the Preamble of claim 1.
  • the locking devices mentioned normally ensure that only one can be switched on by two switching devices.
  • the switching devices to be locked can have a tipping point that either can start relatively early or late.
  • the object of the invention is therefore a locking device for switching devices according to the preamble of claim 1 to meet these requirements Takes into account.
  • the locking device 1a shown in the figures is for locking two switching devices 2 and 3 or circuit breakers and consists of a sliding element 4.
  • the sliding element 4 is arranged displaceably on a carrier plate 5 by guides 6. At the ends of the sliding element 4, pairs of disks 7, 8 are arranged for locking the switching devices 2, 3.
  • the upper disc 9 is fixed to the operating lever, which is not shown in the figures, while the lower disc 10 is fixed to the switching shaft of the switching device.
  • the switching shaft of a switching device is interrupted to the operating lever, so that a relative movement between the switching axis of the switching device and the handle is possible.
  • both locking disks rotate against one another without a bearing being present in the axis of rotation, ie the switching axis is not continuous.
  • the storage and rotational movement of the two locking disks 9, 10 is determined by four Guide slots 11, 17, 18, 19 and four guide pins 12, 13, 14, 16 reached.
  • the guide slots 11, 17, 18, 19 are shaped like a radius and on the upper one Locking disc 9 available.
  • the guide pins 12, 13, 14, 16 face up a cross-sectional expansion so that both disks are held together. They are by a thread or the like on the lower locking disk 9 attached.
  • a guide pin 12 and a fixed to the upper locking disc 9th connected pins 15 are additionally with a second cross-sectional expansion 20 Mistake. These serve as support points for a spring 21 arranged in the axis of rotation with two spring arrays 22, 23. A shortening or increasing the spring travel results from the attachment of the pins 12 and 15 to different Locking disks 9,10, whereby the locking disks 9,10 under Spring tension.
  • Both locking disks 9, 10 are provided with incisions 24 (FIG. 2) Have operating bevels 25. They cause a shift in the Sliding element 4, which has bevels 26 for this purpose.
  • Fig. 2 shows the case that beibe switching devices 2 and 3 are turned off. All cuts 24 of the two pairs of disks 7, 8 are arranged at the same height as the sliding element 4. One of two tips 27 of the sliding element 4 at least partially protrudes into one of the incisions 24.
  • FIG. 4 shows how the second switching device 3 turns off Move the locking washers relative to each other. First only the top one Locking washer as far as it will go, through the guide slots 11,17,18,19 is defined, rotated. The lower disc is not rotated, so that the Incision is not released for immersion of the sliding element. At the further turning the control panel into the out position, as shown in FIG. 5, remain if e.g. the contacts of the switching device 3 to be switched off are welded, the Incisions inaccessible to the sliding element 4. This cannot move to the right be pushed and the first switching device 2 remains blocked in the off position.
  • both switching devices 2, 3 are shown in the off position.
  • the Sliding element 4 is arranged in the center and is not immersed in any of the incisions, see above that both switching devices 2, 3 are unlocked.
  • Figures 8 and 9 show the switch-off process, the contacts of the first Switchgear 2 are welded.
  • FIGS. 10 to 16 show a third embodiment of the locking device 1c.
  • This consists of a Bowden cable 30 and two locking units 31, 32 each connected to the ends of the Bowden cable 30.
  • Each locking unit 31, 32 consists, as in the previous examples, of two locking disks 9c, 10c as disk pairs 7c, 8c with elongated guide holes 11, 17, 18, 19, guide pins 12, 13, 14, 16, a spring 21, which are no further are identified by reference numerals in FIGS. 10 to 16.
  • the locking disks 9c and 10c are provided with a locking cam 33, which consists of a cam track 34 and a locking incision 35 directed perpendicular to the cam track 34 and to the axis of rotation, in which a locking pin 36 can be inserted.
  • the locking pin 36 is connected to a lever mechanism 37, which consists of two spaced-apart and one-sided lever plates 38, a pivot 39, spacers 40, 41 and a Bowden cable receptacle 42.
  • the lever mechanism 37 is pivotally attached to a base plate 43 on one side.
  • the Bowden cable receptacle 42 is arranged at the end opposite the pivot point 44, between the two lever plates 38.
  • the Bowden cable receptacle 42 is provided on its lower side with a pin 45, which protrudes downward into the base plate 43 through a bore 46 in the lower lever plates 38.
  • a compression spring 47 is embedded in the base plate 43, the spring force of which is directed in the opening direction of the lever mechanism and presses on the pin 45.
  • both switching devices are shown in the off position. Both Locking pins 36 are easily immersed in the locking notches 35. In in this area are the locking incisions 35 with the incision opening expanding guide slope 48 provided when switching on a Switching device completely the locking pin from the locking incision 35th presses and opens the lever mechanism of the same switchgear while under the effect of the Bowden cable 30 of the locking pin 36 of the switched off Switching device dips deeper into the locking recess or this Lever mechanism is closed and this switching device is locked, as the Fig. 12 shows.
  • FIG. 13 shows the start of a switch-on process for the second switching device 3, the locking pin of the switching device to be switched on being guided along the cam track.
  • the upper locking washer is relatively displaced relative to the lower locking washer, so that the locking incision is covered.
  • 15 shows the second switching device 3 in the tripped position
  • 16 shows the tensioning of the second switching device 3.
