Circuit breaker interlocking mechanism

Abstract

The invention discloses a circuit breaker interlocking mechanism, which is used for improving the safety performance and the maneuverability of a switch cabinet. The key of the technical scheme lies that a linkage device is arranged on a cabinet body and is in linkage connection with a cabinet door and a circuit breaker, the linkage device comprises a rack, a rotation rod, a linkage sliding plate, a start and stop rod and a first reset spring, the rotation rod, the linkage sliding plate and the start and stop rod are arranged on the rack, the first reset spring sleeves the start and stop rod, one end of the rotation rod is rotatably arranged on the rack, a handle is arranged at the other end of the rotation rod, a swinging block sleeves the rotation rod, a transmission assembly in linkage connection with the circuit breaker is arranged below the swinging block, the rotation rod is in linkage connection with the linkage sliding plate, the linkage sliding plate can be driven to leftwards and rightwards slide on the rack by rotation of the rotation rod and is provided with a baffle sheet and a guide plate arranged below the baffle plate, one end of the linkage rod props against the cabinet door, and the other end of the linkage rod passes through the guide plate to prop against the baffle plate under the effect of a spring.

Description

technical field [0001] The invention relates to the field of switch cabinets, more specifically, it relates to a circuit breaker interlocking mechanism. Background technique [0002] The main function of the switchgear is to open and close, control and protect electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. The components in the switch cabinet are mainly composed of circuit breakers, operating mechanisms, transformers and various protection devices, among which the isolating switch and the grounding switch realize the opening and closing linkage with the circuit breaker through the interlock mechanism. [0003] The circuit breaker can close, carry and break the current under normal circuit conditions and can be closed. At present, when some circuit breakers are closing, the interlock mechanism of the circuit breaker is not safe enough, and sometimes it is easy to misuse. , which brings hidden ...
