摘要
雷直接击中建筑物或线路对建筑物内的设备造成的危害是非常巨大的 本文针对TN接地方式的配电系统建模 ,利用EMTP对雷击不同的TN系统和相同的系统不同的位置时 ,雷电流的分配情况进行了计算研究 研究表明
It is very serious to the device in the buildings in the lightning striking on the building or the transmission lines. In this paper, the TN system including the distribution transformer is modeled, and the lightning current distribution is calculated using EMTP for a direct lightning striking on the protection system of the building in different TN systems or the different points in the same system, and the effect of some parameters on the lightning current distribution is studied. The earth resistance is an important parameter to affect the distribution of the lightning current.
