摘要
通过对1台微机保护装置(插件式)电快速瞬变抗扰度失败试验的介绍,找出失败的原因,认为EFT试验中通过空间辐射的能量不容小视,干扰施加端口采取传导抑制的方法是不能完全克服干扰影响的,对空间的辐射也要采取措施,并指出EFT试验和产品设计的一些注意事项。
It introduces the failed EFT/B test of numerical protection equipment （plug-ins）. According to the hands-on practical experience and the data of wave forms, it discusses the reasons and finds the fact that space radiation is important and powerful enough not to be neglected. When the method of transmission inhibition is applied to interference on port is can not completely overcome the interference. So measures of space radiation should be adopted. Also notices of the test and the design of the device are pointed out.
