Interlocking device of high-voltage switchgear mechanism

Abstract

The invention relates to the technical field of high-voltage switch equipment, and discloses an interlocking device of a high-voltage switchgear mechanism, the interlocking device comprises a high-voltage switch cabinet main body, a handcart chamber, a protection door, a circuit breaker, a control button, partition insulation mechanisms and an auxiliary carrying mechanism; the handcart chamber is arranged at the center position of the right side of the high-voltage switch cabinet main body; the plurality of partition insulation mechanisms are respectively arranged at the corresponding positions of the contacts of the handcart chamber; and the auxiliary carrying mechanism is arranged at the top end of the inner cavity of the handcart chamber. The interlocking device of the high-voltage switch equipment mechanism can replace an existing integral insulating partition plate to integrally block electric shock, closing or opening of a fixed-point electric shock connector is achieved, safety is improved, meanwhile, workers can conveniently conduct high-voltage nuclear phase detection operation, operation is simpler and more convenient, and practicability is high. And moreover, workers are assisted in carrying and mounting the circuit breaker, hands of the workers are prevented from stretching into the high-voltage switch cabinet, mistaken touch of the workers is prevented, and the safety is improved.

Description

technical field [0001] The invention relates to the technical field of high-voltage switchgear, in particular to a mechanism interlocking device for high-voltage switchgear. Background technique [0002] High-voltage switchgear refers to the role of on-off, control or protection in power system power generation, transmission, distribution, power conversion and consumption. High-voltage switchgear is an electrical product with a voltage level of 3.6kV~550kV. High-voltage isolating switch and Earthing switch, high-voltage load switch, high-voltage automatic reclosing and sectionalizer, high-voltage operating mechanism, high-voltage explosion-proof power distribution device and high-voltage switchgear, etc., safety interlock device (safety interlock) means that it can prevent contact with danger before the danger is eliminated. Zone, or a device that can automatically eliminate the dangerous state once it is touched. In order to ensure personal safety during use of high-voltage...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a mechanism interlocking device for high-voltage switchgear, to at least solve the current problem in the prior art that the contact isolation of the handcart room is usually carried out with an integral insulating partition. During the phase operation, the phase check device needs to be inserted into the contact, so the overall insulating partition needs to be removed with an insulating pull rod, which is cumbersome to operate, and when the circuit breaker is pulled and transported, manual operation by the staff is prone to accidental contact, which is very dangerous question
