INTEGRATED HIGH-VOLTAGE ALTERNATING-CURRENT CIRCUIT BREAKER CONTROLLER

摘要

An integrated high-voltage alternating-current circuit breaker controller, comprising a controller main body, a proximitor and a stroke detection circuit, wherein the controller main body comprises a first microprocessor circuit and a switching-off and switching-on control circuit. The controller main body is connected with an external power source thereof, a distribution voltage transformer, a current transformer of the load of a circuit breaker, and a switching-off and switching-on operation assembly arranged in the circuit breaker through an electrical connection line; the controller main body is connected with the proximitor through a communication channel; the stroke detection circuit is connected to the first microprocessor circuit; the first microprocessor circuit is connected to the switching-off and switching-on control circuit; and the controller main body is connected to the switching-off and switching-on operation assembly of the circuit breaker. The controller main body sends out a switching-off instruction signal or a switching-on instruction signal in order to start the switching-off and switching-on operation assembly to control the switching-off operation or switching-on operation of the circuit breaker. The controller is fully functional and has a strong electromagnetic interference resistance, and conducts reliable protection when a short-circuit failure occurs in a load, so that the circuit breaker can be accurately controlled.
