用于防雷工程的电涌保护器的测试研究

Testing methods of surge protective devices for the project defending lightning

针对电源类电涌保护器的试验可进行分类,电源保护器的测试方法除了有规范的要求外,还有许多具体的问题需要研究解决。针对SPD测试中出现的问题进行分析,主要围绕M OV电阻片的漏电流与相关测试所出现的现象进行讨论,对击穿、闪络、燃烧问题进行研究,归纳了现今电涌保护器最常出现的问题。

Testing concerning surge protective devices of power supply can be classified.The testing methods request of some standard,and besides a lot of practical problem need to be solved.In the paper we analyzed the problem in SDP testing,surrounding leak electrical current of MOV resistance and discussed phenomenon in interrelated test.Then we studied problems of breakdown,flashover and combustion,and concluded the usually appearing problem to surge protective devices.
