远程智能漏电试验系统设计

Design of Remote Intelligent Electric Leakage Test System

传统漏电试验不仅容易引起故障和短路隐患,造成不必要损失,而且对操作电工也存在一定的安全隐患。为改变目前状况,设计一种远程智能漏电试验保护系统,该系统不仅克服传统试验方法的局限性,能更加真实地对煤矿井下供电系统各级漏电保护及漏电闭锁进行试验,同时依托供电自动化控制系统,实现远程智能漏电试验,故障复位及后台自动生成操作报表,减少了漏电试验操作的工作量。该系统已在潞安化工集团有限公司某下属煤矿井成功应用并取得较好的运行效果。

Traditional leakage test is not only easy to cause fault and short circuit hidden trouble to cause unnecessary losses,but also has some safety hidden trouble for the operation of electrician.To change the current situation,this paper designs a remote intelligent leakage test protection system,the system not only overcome the limitations of traditional test method,can more real to coal mine power supply system leakage protection and leakage lock test at all levels,relying on the power supply automation control system,realize the remote intelligent leakage test,fault reset and background automatically generated operation report,reduce the workload of leakage test operation.The system has been successfully applied in a coal mine of Lu’an Chemical Group Co.LTD and achieved good operation results.
