摘要: 气体放电管是一种常见的浪涌防护器件。选取2种具有相同静态击穿电压的典型气体放电管（玻璃气体放电管（SPG）和陶瓷气体放电管（GDT））进行试验，研究两者在百纳秒级电磁脉冲作用下的效应特性及其影响因素，并对其电磁脉冲防护能力进行比较。结果表明：对于具有相同直流击穿电压参数的SPG和GDT，在响应时间要求一致时，SPG的动作电压更低；当施加的电压相同时，SPG的响应时间更短；在电流要求低于3 kA的场合， SPG更适用于纳秒级电磁脉冲防护，鉴于其低电容，尤其适于工作在高频段的天馈系统。Abstract: Gas discharge tubes are commonly used as surge protection devices. In this paper, two different types of gas discharge tubes with the same static breakdown voltage, spark gap protector （SPG） and gas discharge tube (GDT), are chosen as research targets, whose responses subjected to the nanoseconds square pulse are compared. With the comparison results, certain rules for their practical application and parts selection are presented. The experimental results show that, for these two types of tubes, SPG has lower applied voltage under the same response time, while under the same applied voltage, SPG's response time is shorter. Above all, SPG has a better performance in nanosecond pulse protection than GDT does when the current is less than 3 kA. Considering its lower parasite capacitance, SPG is more suitable for the protection of antenna systems with high operating frequency.
