摘　　要：针对气体放电管与压敏电阻在雷电波冲击下级间配合的问题,运用雷电波传输理论与雷电冲击电流发生器进行冲击试验相结合的方法.得出:在相同冲击电压下,气体放电管可以增大整体通流效果;气体放电管的残压随总通流呈线性增长,压敏电阻的残压值变化不大,并且与气体放电管的放电电压大小无关;气体放电管的放电电压越大,压敏电阻吸收的能量越多,SPD级间的能量配合效果也更佳。该结论在多级电涌保护器的使用中有一定参考价值。According to the energy coordination problem between gas discharge tube（GDT） and the varistor in the lightning impulse, the conclusions are obtained when the research are based on the method of lightning wave transmission theory and lightning impulse current generator tests. It is concluded that： the gas discharge tube can be increased discharge current capacity when the same impulse voltage applied. Residual voltage of gas discharge tube with through flow increased linearly,varistor residual pressure value changed little and gas put tube discharge voltage size has nothing to do;gas discharge tube of the discharge voltage is greater, varistor absorbs more energy, energy level SPD with effect is better. The conclusion has a certain reference value in the use of multi-level surge protector.
