COMPLETE DISTRIBUTING DEVICE Russian patent published in 2017 - IPC H02B11/133 H02B11/167 

FIELD: electricity.

SUBSTANCE: switchgear apparatus comprises a cabinet having a frame and a door, which houses the switch on the trolley, earthing switch drive, having a shaft, and a lock mechanism having a shutter mounted for vertical movement. The door contains the beams placed to lock the door. In front of the frame is a hole to accommodate grounding of the control handle in the shift points. The locking mechanism of the earthing is made in the form of rods connected to the axis of rotation with a shutter and having inclined to thrust axis of the groove, in which a sleeve placed on the base plate, is rigidly attached to the frame. At the bottom of the thrust, the lever is mounted with the possibility of horizontal movement along a groove formed therein that is associated with the switch lock mechanism. Earthing contact position indicator is located on the mechanism of the earthing switch lock and is connected to the drive shaft of the earthing switch mounted on this cam shaft. Crossbars are mounted for movement parallel to the vertical axis of the door and are in the form of flat plates with grooves of variable width along the axes of the crossbars. Crossbars cover mounted on the frame with abutments cylindrical recesses, the width of each of which corresponds to the thickness of the pins. The diameter of each of the stops in the groove area is formed corresponding to the width of grooves narrow part crossbars. The diameter of the outer portion stops does not exceed the width wide portion protrudes grooves. Crossbars narrowest part of variable width slots are located in the area of grooves at a locked and closed the door, and they cover a wide part stops when unlocking and opening the door. On the side surface of the bolt is made rectangular recess to accommodate one end of the locking rod door lock mechanism, providing a lock bolt and move the door opening. The other end is connected with the locking rod with curtain mechanism in its open position.

EFFECT: design simplification and improvement of operational reliability.
