Abstract Circuit-breaker jump phenomena has frequent impact to the switches and load, anti-pumping circuit is the important part of the secondary circuit to protect the switch. Choose NARI NSP30C operator defend anti-pumping and Siemens 3AH5 breaker defend anti-pumping,for example, analysis two anti-pumping principle. Analysis the incoming-circuit breakers of the 10kV substation used by cooperate may appear between the two sets of the jump condition, Put forward the renovation plan, which can perfect spring prevention circuit.
