Abstract The closing circuit of breaker is generally designed with anti-jump function to prevent repeated closing of circuit breaker. In order to ensure the reliability of anti-jump function, it is necessary to test and check the anti-jump circuit regularly. The general anti-jump test methods focus on verifying the correctness of the circuit and ignore the problem of verifying whether the action time of anti-jump relay meets the requirements, which is easy to lead to misjudgment. This paper introduces a new test method, which can reliably check whether there are abnormalities in the anti-jump circuit and provide guarantee for the safe and stable operation of the equipment.
