摘要
针对固体放电管在组合波发生器冲击下的性能问题,通过固体放电管原理的理论分析,利用理论与试验相结合的方法,采用组合波发生器对固体放电管进行冲击试验,得出:固体放电管的点火电压越高残压越高,并且残压是随冲击电压的增大而增大,点火电压在33.0 V^71.2 V之间的固体放电管承受浪涌的能力好,更耐用;固体放电管的通流与点火电压无关,具有泄放大电流的作用;固体放电管导通后处于低阻状态,具有的限压作用,点火电压越小的固体放电管吸收的能量越多,越有利于设备的保护。该结论在电涌保护器的应用中有一定参考价值。
According to the performance combination wave generator, the conclusions are of solid discharge tube under the impulse of the obtained, based on the combination of the theoretical analysis on solid discharge tube principle and the impulse test by wave generator impulse current generator on solid discharge tube. It is concluded that： the residual voltage of solid discharge tube voltage is increased with the ignition voltage, and the residual voltage is increased with the impulse voltage, the solid discharge tube has good ability and more durable when the discharge voltage is between 33.0 V-71.2 V; The flow of the tube is independent of the ignition voltage and has the function of dropping high current; The solid discharge tube is still in low-resistance after working and has the ability of limited voltage, the less the ignition voltage is the more the energy absorbed by the solid discharge tube, thus the better effect of protection for equipment. The results have reference for the application of surge protective device （SPD）.
