Technical Field

[0001] This utility model relates to the field of switch device testing technology, and in particular to a circuit breaker break-in device. Background Technology

[0002] Circuit breakers are important components of power systems. A circuit breaker is a mechanical switching device that can close, carry, and interrupt current under normal circuit conditions, carry a specified overcurrent for a specified time, and close and interrupt current under abnormal circuit conditions.

[0003] Circuit breaker break-in is a crucial process to ensure the mechanical performance and reliability of circuit breakers. It primarily involves simulating opening and closing operations using break-in equipment to achieve adaptive adjustments to components such as contacts and electromagnets. During break-in testing, circuit breakers generate significant noise, which, if transmitted into the working environment, can harm the health and well-being of operators. Utility Model Content
