Research on Electromagnetic Interference Suppression after Primary and Secondary Fusion of Column Circuit Breakers
The reliability of the column circuit breaker depends on the ability to resist electromagnetic interference and affects the safe and stable operation of the power network,and the difficulty of anti-elec-tromagnetic interference suppression of the circuit breaker is improved after primary and secondary fusion.In view of the electromagnetic interference problem of the circuit breaker,this paper studies the main elec-tromagnetic disturbance source and its generation mechanism after the primary and secondary fusion of the column circuit breaker,and builds an electromagnetic disturbance wave that can simulate the test wave-form;and then designs some anti-interference measures according to the electromagnetic compatibility a-nalysis of the secondary part of the column circuit breaker;and finally tests the anti-electromagnetic inter-ference ability of the column circuit breaker and analyzes the test situation,and the device passes the set immunity test level,thereby explaining the correctness of the anti-electromagnetic interference measures and analysis.
