Abstract

The invention relates to a comprehensive interlocking anti-misoperation switch cabinet which comprises a switch cabinet body, a circuit breaker, a grounding switch, a main braking mechanism, an opening and closing control mechanism, an electromagnetic interlocking mechanism and a mechanical interlocking mechanism. Through cooperation of the main brake mechanism and the opening and closing control mechanism, the function that the switch cabinet cannot be opened in the closed state of the circuit breaker is achieved, the situation that a worker enters an electrified interval is prevented, and the safety of the switch cabinet is improved; by arranging the electromagnetic interlocking mechanism, the function that the circuit breaker cannot be closed in a door opening state is realized, and the condition that a worker enters an electrified interval is prevented; meanwhile, the feedback speed of opening the switch cabinet is increased through the electric signals, and the situation of misoperation caused by time difference generated by too long feedback time is prevented; through the cooperation of the main brake mechanism and the mechanical interlocking mechanism, the function that the grounding switch cannot be closed in the closed state of the circuit breaker is realized, the situation that the grounding switch is mistakenly closed in the closed state of the circuit breaker is prevented, and the safety of the switch cabinet is improved.
