hose stream test

1The heavy pulse current test results using the optimal grounding electrode obtained from the simulation experiment,suggest that the impulse coefficient α is not a fixed value which is related with the impulse current peak value,the type and.

通过对模拟试验中最优化的电极进行冲击大电流试验,得出冲击系数α的大小与冲击电流幅值、电极形状和布置形式有关,不是一个定值;接地体在防雷保护中作用的大小主要取决于冲击接地阻抗和过渡过程的特征,而不是工频接地电阻。
