摘要：

介绍了福建水口发电集团有限公司的500 kV升压站,采用特殊四边形接线方式,共安装有4台高压开关,由于在高负荷用电环境下,无法全站停电检修,多数情况是单条线路停电,开关一端带电、致使开关不能正常进行预防性试验。而采用新型的测试计算法,检测HGIS内部开关及刀闸的接触电阻,便于和出厂数据进行对比。既确保了试验过程中设备和检修人员的人身安全,也缩短了线路停役时间,提高了社会效益。在当前新的用电环境下具有一定的推广意义。

Abstract:

This article introduces the 500 kV booster station by Fujian Shuikou Power Generation Group Maintenance Company,which uses a special quadrilateral wiring with 4 high voltage switches.In the electrical environment of the high-load,a station blackout overhaul is impossible.In most cases it is a singleline power outage,in which one end of the switch stays live;as a result,the switch can not be normal for preventive trials.New test calculation detects the HGIS internal switch and disconnector contact resistance for easy comparison with factory data.It ensures the safety of equipment and maintenance personnel in the testing process,shortens the line suspended service time,and increases social benefits,thus deserving promotion under the new electricity environment.

Key words: quadrilateral electrical wiring;single end electric line;the conductive circuit resistance
