Abstract

The invention relates to a bus grounding knife-switch interlocker. The bus grounding knife-switch interlocker comprises two locking plates, a crescent plate, adjusting bolts, a pull rod and a locking groove, wherein the two locking plates are arranged on bus knife-switch movable contact arm bases at two sides respectively; two ends of the pull rod are connected with the crescent plate and the locking groove through the adjusting bolts respectively; and the other side of the crescent plate is fixed on a transverse rotating connecting rod of a grounding knife-switch. Based on the original knife-switch design, the effective mechanical locking of a double-bus grounding device in a locking state on bus isolating switches at two sides can be thoroughly realized, accidents of mistakenly switching on the bus isolating switches and the bus grounding knife-switch are eliminated, and the interlocker has a high safety coefficient and a strong defense function.

Description

technical field [0001] The invention relates to a busbar grounding knife switch interlock. Background technique [0002] The isolating switch on the grounding side of the busbar can only achieve mechanical defense locking with the main body grounding switch, but in the double-bus connection mode, the grounding switch cannot simultaneously realize the mechanical locking of the bus isolating switch on the non-grounding switch side. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a busbar grounding knife switch interlock to prevent misoperation accidents. [0004] In order to solve the problems existing in the prior art, the technical solution adopted in the present invention is: [0005] The busbar grounding knife interlocker includes two locking plates, a crescent plate, an adjusting bolt, a pull rod and a locking slot. The two locking plates are respectively installed on the bases of the moving contact arms of...
