摘　　要：本文介绍一特大型现代化矿井的高压漏电保护系统。该保护系统能集中监护地面变电所６段母线６４路馈出线、井下中央变电所８段母线４８路馈出线，以及井筒中的四对并联下井电缆；具有自动选线、选相、声光报警、数字显示、自动记录及自检演示等功能；还能区分永久性漏电和瞬间性漏电。This paper presents a high--voltage leakage protective system for the most modernization mine. This system is able to monitor 64 feeder lines which belong to 6 sections of bus- bar in ground substation, 48 feeder lines which belong to 8 sections of bus--bar in the bottom substation, and also 4 pairs of parallel down--shaft cables. when single phase earthingof leakage in the electrical network takes place , it can send out an alarm with sound and lightquickly,and shows the number of the pravity line correctly, and type the pravity informationautomatically.
