玻璃气体放电管与陶瓷气体放电管的纳秒脉冲响应特性比较
Comparison of the response characteristics under nanosecond pulse of spark gap protector and gas discharge tube
摘要
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, certaln rules for their practical application and parts se⁃lection are presented. The experimental results show that, for these two types of tubes, SPG has lower ap⁃plied 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 protec⁃tion of antenna systems with high operating frequency.关键词
