1) number of lightning strokes
雷击次数
2) lightning stroke times estimated in a year
年预计雷击次数
3) Secondary Lightning Strike
二次雷击
1.
Computational results show that the reflection and superposition of small-amplitude lightning intruding waves caused by secondary lightning strike and transferred on lines led to circuit breaker restrike and CT flashover on Beijiao Substation side and eventual explosion of circuit breaker.
利用ATP-EMTP电磁仿真计算程序对广州供电局500kV北郊变电站北石乙线因雷击造成线路电流互感器(current transformer,CT)U相闪络、断路器U相爆炸过程中可能产生的过电压进行了仿真计算,分别计算了切空线过电压和二次雷击过电压。
4) expected average annual number of lightning flashes to earth
年平均预计雷击次数
5) estimating times per year on building by thunderstorm
建筑物年预计雷击次数
6) predictive annual average lightning stroke times
年均预计雷击次数
1.
By analyzing the local lightning data and finding out the laws,predictive annual average lightning stroke times of buildings and overhead lines in different environment are got,providing basis for better lightning protection design and effective lightning disaster prevention.
通过分析本地雷电资料,找出其规律性,得出本地不同环境的建筑物及架空线路的年均预计雷击次数,为设计更完善的防雷方案,有效地预防雷电灾害提供依据。
