本文研究了各种类型断路器(MOCB（Minimum Oil CB）、VCB（Vacuum CB）、ABCB （Air Blast CB）和GCB （SF6 Puffer CB）的电路状态与斩波电流值的关系。除压断路器外，每个断路器斩波电流随断路器并联电容的增加而增加，但当串联电阻连接到该电容时，斩波电流减小。在MOCB、ABCB和GCB中，切电流前的现象非常相似，而在VCB中则完全不同。从实验和理论两方面对这些问题进行了深入的研究。
The authors have investigated the relation between the circuit conditions and the chopping current values of various types of circuit breakers, including MOCB(Minimum Oil CB), VCB(Vacuum CB), ABCB (Air Blast CB) and GCB (SF6 Puffer CB). Excepting VCB, each breaker chopping current increases with increase of the parallel capacitance to the breaker, but it decreases when a series resistance is connected to this capacitance. Concerning to MOCB, ABCB and GCB, it was found that the phenomena just before current chopping quite resemble each other, while as for VCB, it differs from others completely. These were investigated throughly from experiments and theory.
