Circuit breaker three-position status signal acquisition and output device

Abstract

A circuit breaker three-position state signal acquisition and output device comprises a circuit breaker drawer and a circuit breaker body, the circuit breaker body being inserted into the drawer. The device is characterized in that: the drawer is mounted on the drawer, and the circuit breaker body is mounted on the body. As the circuit breaker body is inserted into the drawer, at least one set of separation position sliding modules, a test position sliding module, and a contact position sliding module in the body contact assembly can sequentially contact at least one corresponding set of separation position modules in the drawer contact assembly. The test position module and the contact position module contact each other to connect the circuits for the three position states of the circuit breaker: separation, test, and connection. The present invention utilizes the different insertion depths of the circuit breaker body into the drawer to connect circuit loops in different states, thereby enabling the acquisition and output of the circuit breaker three-position signals.
