摘　　要：电气电子设备可能由于雷击、运行操作中的过压,而承受浪涌电压(电流),必须采用浪涌抑制器件构成保护电路加以抑制。浪涌测试模拟了在电源线和长信号线上可能出现的高能量但相对较慢的瞬态过压现象,浪涌抑制器件与被保护电路并联,来观察是否能起到对电路更好的保护作用。Electrical and electronic equipment may be struck by lightning or running operations in over-voltage, will withstand the surge voltage （current）Must adopt the surge suppression circuit protection devices posed to be inhibited.The test can simulate surge in the power cord and a long line signals that may arise high-energy, surge suppression devices will be paralleled with protected circuits, to observe whether or not to play on the circuit better protection.
