surge arrestor 电涌[涌浪]放电器 A small gasfilled tube with two electrodes, one which is connected to ground and the other to the circuit that is to be protected from highvoltage pulses. The gas ionizes at a predetermined voltage, thus shunting pulses to ground. 一种有两个电极的小型充气管,其中一个电极接地,另一个电极与一个要求防高压脉冲的电路 相连。在某一预定电压下气体电离,从而把脉冲短路到地上。 |
