Abstract
Description
technical field
[0001] The invention relates to the technical field of circuit breaker detection, and in particular relates to a performance detection device for an operating mechanism of a circuit breaker. Background technique
[0002] A circuit breaker refers to a switching device that can close, carry and break current under normal circuit conditions and can close, carry and break current under abnormal circuit conditions within a specified time. Circuit breakers can be used to distribute electrical energy. Start the asynchronous motor frequently, protect the power line and the motor, and automatically cut off the circuit when they have severe overload, short circuit and undervoltage faults. Its function is equivalent to the combination of a fuse switch and an overheating relay. , and generally do not need to change parts after breaking the fault current. At present, circuit breakers have been widely used in power systems. When repairing circuit breakers, common faults ar...
