Abstract

The invention discloses a manual interlocking device of a three-station mechanism. The manual interlocking device comprises a side board arranged on the mechanism, a DS baffle and an ES baffle, wherein the DS baffle and the ES baffle are arranged on the side board. A mechanical interlocking device supporting board, a pair of driving pins which are vertically connected in a sliding mode along the side board, and a pair of cams which are arranged along the inner sides of the driving pins in parallel are arranged at the front end of the side board. Interlocking pins which slide relatively are arranged on the supporting board, and the interlocking pins correspond to locking holes in the DS baffle and the ES baffle. The inner side, corresponding to the interlocking pins, of the supporting board is connected to a hinge pin and provided with a pair of driving levers, and one ends of the driving levers are matched with the driving pins. The driving pins link the driving levers to rotate through manual or electric operation, the interlocking pins act to be inserted into the locking holes in the DS baffle or the ES baffle to lock the DS baffle or the ES baffle through the driving levers. The manual interlocking device of the three-station mechanism can be automatically locked when manual operation reaches an expected position, and the interlocking function of manual operation of the three-station operating mechanism used in cooperation with a high-voltage isolation / grounding three-station switch is achieved.

Description

technical field

[0001] The invention relates to a manual interlock of a three-position mechanism used in a high-voltage isolation / grounding three-position switch and an interlock device thereof. Background technique

[0002] The high-voltage isolation / grounding three-position switch is a three-position switch that combines a conventional isolating switch and a grounding switch into a common box. It has been widely used in power transmission and transformation equipment——SF6 gas-insulated fully enclosed combined electrical appliances. The operating mechanism must also meet the function of three-station operation. For the safety of people, equipment and power transmission and transformation systems, certain preconditions must be set for the operation of the three-station mechanism, and the set effect must be satisfied after the operation, including electric operation and manual operation. However, when the existing three-station mechanism is operated manually, the status info...
