摘要
近年来,35 kV电力线路频繁发生雷击断线事故,损失较大。通过调查研究,曾有一种解决方案强调从改善绝缘子性能方面来着手解决这一问题。根据导线热效应理论对雷击断线事件进行仔细分析,从线路继电保护的角度出发,提出解决措施,并通过实践,取得良好效果。
In recent years, disconnection faults caused by lightning strike happened frequently in power line, which has caused heavy lesses. After investigation, there has been a resolution whose emphasis is to improve insulator performance to solve this problem. But a new method is put forward here： the disconnection event caused by lightning strike is analyzed carefully according to the conductor hot effect and the measures are given as viewed from line relay protection. The good effect has been obtained through the practice.
