| Abstract: | This article introduces a microcomputer-based selectively protective system and device of 660V/1140V low-voltage underground power system. This device includes selective leakage-current protection of longitude and transverse on the principle of direct current detecting and the direction of zero order current and time lag. In addition, the mainswitch possesses the function of insulance detecting with total power network, the disrtibuting switch possesses the function of leakage current lock and one time recovery supply. |
