带电处理多分裂线路引流板发热缺陷新方法

Live Working Method for Multi-Split Line Drainage Plate Heating Defects

多分裂输电线路耐张线夹引流板与跳线引流板在运行中,由于连接螺栓松动、腐蚀、接触不良、漏涂导电脂、设备老化等因素,致使耐张线夹引流板与跳线引流板间接触电阻增大,出现引流板位置发热超标现象,需要及时带电消除缺陷。研究出采用分流线法带电处理多分裂线路引流板发热缺陷,该方法经过现场应用,能够安全地带电打开引流板,检查处理发热缺陷,打开引流板时不会出现拉弧现象,操作安全可靠。

During the operation of the multi-split line strain clamp and jumper drainage plates, the loose coupling bolts connection, corrosion, poor contact, lack of coating conductive grease, equipment aging and other factors may increase with the contact resistance between the drainage boards, and consequently overheat fault occurs in the position of drainage boards in demand of live eliminating defects in time. This research has developed a solution by using shunt line. Through field application, the method can be used to live open drainage plate safely, and check and solve heating defects. When the drainage board is opened, the arc phenomenon does not appear, so the operation is safe and reliable.
