新杭线Ⅰ回路雷击闪络跳闸分析及绕击率、跳闸率的实测计算

根据新机线I回路雷电流幅值的实测结果，分析了该线从投运至1994年的34a中的55次雷击跳闸和68次雷击问络的类型——绕、反击，从而求得该线的绕击率和雷击跳闸率的实测值。此外，还对新机线Ⅰ、Ⅱ回路同年份的单位雷击跳闸率作了计算和比较。

Based upon the measured results of lightning current amplitude in Xing - hang line I, the kinds offifty-five lightning trip and sixty-tight lightning flasbover shielding failure and back flashoer are analysed from1961 to 1994. The measured values of shielding failure and lightning trip are achieved- Furthermore, unit light-ning trip rate of xing - hang line Ⅰ、Ⅱ in the same year are calculatai and compared.
