摘要

为了进一步研究电涌保护器（surge protective device

SPD）级间能量配合失效的问题

依据IEC 61643的规定

利用波的传输理论与基尔霍夫定律进行理论分析后

再进行冲击试验

试验发现:SPD在能量配合失效时

其级间的退耦元件受到的损伤往往比主要防雷元件更为严重。研究表明:在8/20μs冲击电流的多次冲击作用下

退耦元件的电气性能将发生变化。同样绕制情况下

线径越大的电感冲击损伤越小;同一温度下

功率越大的电阻冲击损伤越小

且镀膜型电阻的电气性能较绕线型电阻更稳定。从而提出:在SPD的能量配合试验中

应先校验级间退耦元件电气性能的一致性

后分析冲击数据。这在SPD的级间参数配置研究过程中

具有一定的实际参考意义

Abstract

In order to reasearch the problem of the energy cooperation failure in multi-level surge protective device（SPD）

based on transmission line theory & Kirchhoff law & the request of IEC 61643

then through impulse test

it would find that the damage to decoupling component is more severe than main lighting protection component when SPD fails in energy cooperation.Results show that decoupling component’s electrical specification may be changed with repeated 8/20 μs impulse current.In the same winding case

the greater wire diameter

the stronger stability of the inductance. In the same temperature

the stronger resistance has better stability.And coating resistance is more reliable than winding resistance.It comes to the conclusions that decoupling component should be verified first

then analyzing the impulse data of SPD.The conclusions will be meaningful to the parameter setting of SPDs.
