摘要
文章介绍了顾桥煤矿10kV供电系统在电力系统中的重要位置及10kV供电系统继电保护的基本原理,着重介绍几种常见的电流保护:反时限过电流保护、定时限过电流保护、电流速断保护,并分析了各类保护装置的基本构成、保护范围、动作原理、配合方法、优缺点。
The lOkV perceptual load in the 110kV transformer station of Guqiao Coal Mine of Huainan Coal Mine Co.,ltd is so heavy that it produces large amount of reactive power, lowers power factors, makes some large fixed equipments start and stop frequently, brings about serious load fluctuations and short repeating cycle time, all of these impact the power supply system greatly. This article is about how to eompensatorilly govern the power supply system of this coal mine.
