防带电加量型试验线的研制

Development of Electricity-proof Loading Test Line

在继电保护设备的加量试验工作中,若误接线于运行设备带电的接线位置上,可能会引起保护设备误动作跳闸,造成供电线路事故停运,影响电网的安全稳定。针对常规万用表验电操作的繁琐性及作业人员可能存在的疏忽,研制具有验电提示功能的试验导线,将接线和验电操作结合,在接线过程中即能提醒作业人员接线位置是否带电运行,有效降低因疏忽未验电而误操作导致的电网事故。

In the loading test of relay protection equipment,if it is wrongly connected to the wiring position of the running equipment,it may cause the protection equipment to misoperate and trip,resulting in the power supply line accident outage,affecting the safety and stability of the power grid.In view of the conventional multimeter to check the electric operation cumbersome and homework personnel possible negligence,experiments wire,which has the function of test electric prompt to combine and check electrical wiring operation,in the process of wiring can be clearly remind workers wiring location are charged operation,effectively reduce the due to negligence did not check electric power grid accidents caused by wrong operation.
