摘要
10kV架空输电线路由于长期处于露天运行,它具有线路长、海拔高、环境差,交通不便,容易遭受自然灾害的特点。因此,运行中的10kV架空输电线路事故频繁,影响广播电视安全播出,更为严重的是存在着引发森林火险隐患的严重安全问题。本文对高山台专用输电线路容易发生的故障进行分析,并提出只有通过行之有效的技改和预防措施,才能提高供电系统的可靠性,安全性,减少电力故障造成的损失。
Due to the outdoor transmission for a long time, 10kV overhead transmission lines are always in an envirenment with bad weather, inconvenient transpotation and frequent natural disasters. Therefore, power accidents of 10kV overhead transmission lines take place frequently,which always influence the normal transmission of radio and television of the relay station.More serious is that there are serious security problems of igniting wildfi res. The thesis is oriented to analysis power accidents of 10kv overhead transmission lines,and put forwards some effective measures about prevention accidents and technical innovation,in order to improve the reliability of power supply system and reduce the loss of power accidents.
