摘要
本文介绍了风筝线、驱鸟彩带和渔网三起输电线路外力破坏跳闸事故情况,对3种漂浮物的绝缘特性进行了试验研究,主要试验项目为绝缘电阻测量和干、湿工频耐受试验。基于试验研究结果分析了跳闸事故成因,提出了降低风筝线等漂浮物跳闸事故的预防措施。
In this paper, three kinds of tripping operation faults happened on transmission line are introduced, including kite line, displacing bird ribbon and fishing nets. The insulation characteristic of the external debris is studied. The main test items consist of insulation resistance measurement, dry and wet power frequency withstand test. Based on the experimental results, the cause of multi-class outside destroy is analyzed. The prevention measures for reducing outside destroy are put forward.
