摘要
为了防止架空线路瓷绝缘子掉串危及电网安全运行,以220 kV丰金线50号耐张塔耐张双串绝缘子串其中一串脱落的危急缺陷及220 kV万文I线61号线杆遭雷击后B相绝缘子串掉串事件展开分析,结合掉串绝缘子的机电试验数据,详细分析了瓷绝缘子串掉串的原因,并提出了整改防范措施。
The paper analyzed porcelain insulator string breakage happened in 220 kV Fengjin line No.50 strain tower and 220 kV Wanwen I line.In order to prevent transmission line porcelain insulator string breakage,reasons and countermeasures for it were presented according to the result of string breakage test.
