CN202816730U - Interlocking mechanism of breaker secondary plug - Google Patents

Abstract

The utility model discloses an interlocking mechanism of a breaker secondary plug. The interlocking mechanism comprises a breaker panel having a plug hole. An inner side of the breaker panel is provided with a secondary wire socket fixing plate. An interlocking plate that can move in a reciprocating manner along a horizontal direction is arranged between the breaker panel and the secondary wire socket fixing plate. The interlocking plate can move in a reciprocating manner to allow the plug hole on the breaker panel to be opened or closed. The interlocking plate is arranged on the breaker panel via an interlocking rod. The interlocking rod is provided with a spring that enables the interlocking plate to be restored. The interlocking plate is equipped with an operating handle that extends out of a front surface of the breaker panel. According to the interlocking mechanism with the above structure, the secondary plug is prevented from being plugged off or plugged in by mistake. The interlocking mechanism is reliable and convenient to operate and use.

Description

Circuit breaker secondary plug interlocking mechanism

technical field

The utility model relates to a circuit breaker secondary plug interlocking mechanism, which belongs to the technical field of high-voltage power transmission and distribution equipment. the

Background technique

The traditional circuit breaker or switchgear does not have any interlocking mechanism, and the secondary plug can be plugged and unplugged under any circumstances. When the operator's careless operation will bring certain safety hazards to the operator, it does not meet the requirements of the operating specifications. , At the same time, the operator mistakenly inserts or unplugs the secondary line plug, which brings great inconvenience to the production. the

Contents of the invention

The technical problem to be solved by the utility model is to provide a circuit breaker secondary plug interlocking mechanism that can effectively prevent misplugging and unplugging of secondary line plugs. the

In order to solve the above-mentioned technical problems, the circuit breaker secondary plug interlocking mechanism of the utility model includes a circuit breaker panel with an insertion hole, the inner side of the circuit breaker panel is provided with a secondary line socket fixing plate, and the circuit breaker A chain plate that can reciprocate horizontally is arranged between the fixed plates of the line socket, and the reciprocating movement of the chain plate can open or close the insertion hole on the panel of the circuit breaker; There is a spring that can reset the interlocking plate, and the interlocking plate is provided with an operating handle protruding from the front end of the circuit breaker panel. the

A support plate for supporting a chain link is provided on the inner side of the circuit breaker panel, and a retaining ring structure is provided on the chain link, and the spring is installed between the support plate and the retaining ring structure. the

After adopting the above-mentioned structure, due to the interlocking plate that can move back and forth along the horizontal direction and the spring that can reset the interlocking plate on the interlocking rod, when the interlocking plate moves to the rightmost position, the secondary line plug can be inserted into the secondary line. In the socket of the secondary line, the secondary plug that is inserted by releasing the operating handle is fixed in the socket through the interlocking plate, and the plug cannot be pulled out without moving the interlocking plate, thereby preventing accidental pulling out and insertion of the secondary plug. Function, reliable and convenient operation. the
