概述
Summary
FN7-12DR 型交流高压负荷开关(以下简称负荷开关)是一种新型产气式户内高压负荷开关,适用于交流50HZ,额定电压12KV的三相交流电力系统中,作为开断负荷电流及关合短路电流之用。
FN7(C)-12型系列高压负荷及熔断器组合电器是在FN7-12系列高压负荷开关的基础上,增加侧面操作机构、使得安装更加简捷方便,能够满足广大用户的不同要求。
FN7-12DR is used in three-phase AC power network of AC 50Hz、rated voltage 12KV for breaking load current and controlling short-circuit current.
FN7(C)-12 type H.V load switch and fuse box is basied on the FN7-12 series H.V load switch. with operating mechanism. Make the installation more simpler. Can meet orders needs.
