High-voltage vacuum circuit breaker driving device

Abstract

A high-voltage vacuum circuit breaker driving device disclosed by the present invention comprises a bottom plate, the front part of the upper end of the bottom plate is provided with a vertically through opening, the front end of the bottom plate is fixedly provided with a mounting plate, the mounting plate is of an L-shaped structure, and the inclined surface of the upper end of the mounting plate is fixedly provided with three wire inlet ends. An A-phase leading-out terminal, a B-phase leading-out terminal and a C-phase leading-out terminal are sequentially and fixedly installed on the rear portion of the upper end of the bottom plate from left to right, and current transformers are fixedly installed on the front portions of the outer surfaces of the A-phase leading-out terminal and the C-phase leading-out terminal. According to the high-voltage vacuum circuit breaker driving device, the driving mechanism and the execution mechanism are arranged to cooperate with each other to realize automatic opening and closing of the isolation knife, so that the opening and closing efficiency and the personal safety of operators are improved; and a first limiting groove, a first limiting rod, a fan-shaped limiting groove and a second limiting rod are arranged to cooperate with one another to limit the rotation angle of the movable rod, so that the situations of excessive switching-on, improper switching-off and the like are effectively avoided.

Description

technical field [0001] The invention relates to the technical field of high-voltage vacuum circuit breakers, in particular to a driving device for high-voltage vacuum circuit breakers. Background technique [0002] With the rapid development of my country's economy and the continuous increase of power supply, especially the increasing dependence of various customers on power, in order to improve the reliability of power supply of the power grid, the pole-mounted circuit breaker is often used in the connection, segmentation, In order to improve the power supply reliability of the power grid, the management of the pole-mounted circuit breaker is a weak link of the county-level power supply enterprises. Only when it is included in the standardized and institutionalized management can it play its due role, otherwise it will directly It affects the security management and power supply reliability of the enterprise. The management of pole-mounted circuit breakers should be checked ...

AI Technical Summary

Problems solved by technology

[0003] The existing high-voltage vacuum circuit breakers have the following disadvantages: 1. Most of the existing high-voltage vacuum circuit breakers require operators to manually pull and close the isolation knife, which is not only cumbersome to operate but also has certain safety hazards; 2. The existing high-voltage vacuum circuit breakers The driving structure in the vacuum circuit breaker lacks limit measures, and it is prone to phenomena such as excessive pulling of the isolation knife or insufficient pressing of the isolation knife, which affects the safety of use
