Gas-insulated ring main unit interlocking device

Abstract

The invention discloses a gas-insulated ring main unit interlocking device, and the device comprises a cabinet body, a circuit breaker mechanism and an isolation mechanism; an isolation abdicating hole rotates to a corresponding isolation switch working station, a circuit breaker is closed, and the lower end part of a first interlocking rod is inserted into the isolation abdicating hole, thereby preventing an isolation switch from being disconnected in an electrified manner; the lower end part of the second interlocking plate is pressed against the notch of a circuit breaker locking trigger block, and the second interlocking plate is supported by the second interlocking plate after the isolating switch is switched off, so the circuit breaker mechanism extends out of the interlocking plateto move upwards to lock the circuit breaker, and the circuit breaker is prevented from being closed mistakenly; after the isolating switch is switched on, the cabinet door interlocking triggering arcblock presses the cabinet door interlocking roller downwards to drive the cabinet door locking rod to be inserted into the cabinet door locking hole, the cable chamber cabinet door is prevented from being opened, the electrified interval is prevented from being mistakenly entered, and the five-prevention interlocking requirement is met; the structural design is simple and reasonable, the size is small, and the stability is good.

Description

technical field [0001] The invention relates to the field of high-voltage cabinet structures, in particular to an interlocking device for a gas-insulated ring network cabinet. Background technique [0002] At present, there are few domestic manufacturers producing environmentally friendly insulating cabinets, and most of the interlocking devices adopt soft interlocking, with complex structures, low reliability, high cost, and large space occupation. Contents of the invention [0003] The purpose of the present invention is to solve at least one of the technical problems existing in the prior art, and to provide an interlocking device for gas-insulated ring network cabinets, which can meet the requirements of five-proof interlocking, has high reliability, simple and reasonable structural design, and small volume ,save space. [0004] An interlocking device for a gas-insulated ring main unit according to an embodiment of the first aspect of the present invention, comprising...
