Abstract

The invention provides an intelligent withdrawable circuit breaker, which is used to be installed in a power distribution cabinet, including a circuit breaker body and a controller, the controller is electrically connected with the circuit breaker body, and the intelligent withdrawable circuit breaker also includes a current sensor and a controller. At least one of the temperature sensors. The intelligent withdrawable circuit breaker of the present invention can automatically detect information such as voltage, current, temperature, etc. and perform fault diagnosis, and can realize short-circuit fault, overload fault, over-current fault, over-voltage fault, under-voltage fault, over-temperature fault and no fault. Diagnosis of various fault states, fault diagnosis function is perfect.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to an intelligent withdrawable circuit breaker. Background technique [0002] As one of the most extensive and important switching electrical equipment in the power system, the circuit breaker is used in the power supply and distribution system to distribute electric energy and protect lines and power equipment from overload, undervoltage, short circuit and other faults. The drawer circuit breaker is suitable for infrequent conversion and infrequent starting of motors in circuits with AC 50Hz, rated working voltage of 690V and below, and rated working current of 100 to 800A. Traditional draw-out circuit breakers cannot automatically detect information such as voltage, current, temperature, and perform fault diagnosis. The installation cost is high, and remote monitoring and control cannot be performed. SUMMARY OF THE INVENTION [0003] In view of this, the present invent...
