Abstract

Disclosed is a plug interlock device for a vacuum circuit breaker. Only after a plug is completely mounted to a connector, an insertion or withdrawal operation by a vacuum circuit breaker is performed. Accordingly, while a breaker body is moved to a 'RUN' position from a 'TEST' position, or when an operation is performed at a 'RUN' position, the plug may be prevented from being separated from the connector. This may prevent an accident.

Description

technical field [0001] The invention relates to a plug interlocking device for a vacuum circuit breaker. Background technique [0002] Generally, circuit breakers can be classified into fixed types and retractable types. The fixed type circuit breaker has only a main body and is fixed to the inside of a panel of a switchboard. On the contrary, a retractable type circuit breaker has a case such as a bracket for easy maintenance and repair, and the retractable type circuit breaker is configured such that only a circuit breaker main body is inserted into or retracted from the case. [0003] A retractable type circuit breaker (hereinafter will be referred to as a 'circuit breaker') is housed in a switchboard together with other electrical equipment to drive power generation equipment, substations, electric motors, and the like. [0004] The circuit breaker may be configured such that a circuit breaker body of the circuit breaker is electrically connected to or separated from a...
