The working principle is: when voltage is applied to both ends of the gas discharge tube voltage reaches the gas is ionized, the gas discharge tube of a non-self-sustained discharge transition to self-sustaining discharge, the discharge was low resistance conducting state, you can instantly by a large current, the gas discharge tube after breakdown low voltage can be maintained to less than 30V; Semiconductor discharge tube: it is composed by solid four-layer SCR (Silicon Controlled Rectifier) structure. Discharge starts operation when the surge voltage exceeds the break-over voltage semiconductor discharge VBO, when the discharge tube operates in the fold-back device, the role of the voltage across the discharge tube is maintained at a very low (approximately 20V or less) can maintain its low resistance state, absorb surge and protect the devices.

其工作原理为:当加在气体放电管两端的电压达到气体电离电压时,气体放电管由非自持放电过度到自持放电,放电管呈低阻导通状态,可以瞬间通过较大的电流,气体放电管击穿后的维持电压可以低到30V以内; 半导体放电管:由故态的四层可控硅结构组成,当浪涌电压超过半导体放电管的转折电压VBO时放电管开始动作,当放电管动作后在返送装置,的作用下放电管两端的电压维持在很低(约20V以下)时就可以维持其在低阻高通状态,起到吸收浪涌保护后级设备的作用。
