Abstract

The invention provides an intelligent draw-out type circuit breaker. The intelligent draw-out type circuit breaker is used for being installed in a power distribution cabinet body and comprises a circuit breaker body and a controller, wherein the controller is electrically connected with the circuit breaker body. The intelligent draw-out type circuit breaker further comprises at least one of a current sensor and a temperature sensor. According to the intelligent draw-out type circuit breaker, information such as voltage, current and temperature can be automatically detected, fault diagnosis can be carried out, diagnosis of various fault states such as a short-circuit fault, an overload fault, an overcurrent fault, an overvoltage fault, an under-voltage fault, an over-temperature fault and no fault can be achieved, and a fault diagnosis function is complete.

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 type circuit breaker is suitable for infrequent switching and infrequent starting of motors in circuits with AC 50Hz, rated operating voltage 690V and below, and rated operating current 100 to 800A. Traditional drawer-type circuit breakers cannot automatically detect voltage, current, temperature and other information and perform fault diagnosis. The installation cost is relatively high, and remote monitoring and control cannot be performed. Contents of the invention [0003] In view of this, ...
