In order to ensure the correctness and reliability of anti-bouncing circuits,anti-bouncing test needs to be carried out before the initial production of circuit breakers.This paper clarifies the principles of two anti-bouncing modes,i.e.,an-ti-bouncing via operation box and via in-situ mechanism box,analyzes the steps and objectives of the opening and closure anti-bouncing tests,and puts forward the precautions for the pre-acceptance check.The paper provides useful information for enhancing substation on-site pre-acceptance check practices in the future.
