高压限流熔断器-负荷开关开断电路时转移电流的分析

Analysis of Transfering Current when Breaking Circuit by High-voltage Current-Limiting Fuse and Box-load Switch

阐述了转移电流的概念,探讨了转移电流的计算方法和选值方法,得出了转移电流和弧前时间的关系曲线,论证了转移电流和额定转移电流的关系。

The concept of transfer current is expouned, and the calculation and the method of selecting the numerical value of transfer current are approached. It educes curre of relation between transfered current and forward-arc time, demonstrates relation between transfered current and rated transfer-current.
