摘要
随着工业电气设备和家用电器中含有脉动直流成分的电源越来越多,A型剩余电流保护器(RCD)的应用和推广显得相当重要。就A型剩余电流保护断路器的原理及特性进行阐述。对故障电流含直流分量的情况进行介绍,然后对RCD在配电系统中的应用作简单探讨。
As there are more and more power sources which contain pulsing DC cemponent in industrial elec- trical devices and home aplianee, it is very important to apply and extend an A-model residual current device （RCD）. The principle and characteristics of A-model RCD were expounded. The condition of fault current contai- ning DC component was introduced, and the application of RCD in power distribution system were discussed.
