10kV 备用电源自动投入装置的改进

The Improvement on Actomatic-Input System for 10kV Spare Power Supply

提出了备用电源自动投入装置的改进方案并有多台在武钢冶炼区域供电系统中使用，动作成功率极高，可靠性较传统装置大为提高，保障了供电系统的安全供电。

This article has put forward the improving plan of BZT set-the devices of automatic input system for spare power supply, some of which have been used in power supply system of melting sections of Wuhan Iron & steel Co. Practically. The action is greathy successful, its reliability is much better than the traditional BZT set thus the safety of the power supply system is assured.
