striking distance

用法例句

Analyzing test data by Matlab, the relation curves of 50% lightning impulse voltage to dry-arc distance for insulators with different rated voltages are obtained; the relational expressions of 50% lightning impulse voltage to dry-arc distance for insulators with rated voltage from 110 kV to 500 kV are fitted.

利用Matlab分析试验数据,得到了不同电压等级绝缘子50%雷电冲击电压与干弧距离的关系曲线,拟合出了110~500kV绝缘子50%雷电冲击电压与干弧距离的关系表达式,通过逐步提高冲击电压的峰值研究并绘制出了110kV绝缘子的伏秒特性曲线,为复合绝缘子的选型提供了参考。

The dry arcing distance of 500 kV A.

目前标准中并没有规定500kV交流瓷外套避雷器的干弧距离,其干弧距离由型式试验确定。
