摘要
本文以变电站的主要干扰源及耦合方式作为切入点,就变电站保护二次电缆屏蔽层接地方式进行研究,论述屏蔽层的抗干扰作用,再以此为基础,对屏蔽层接地的不同方式进行重点分析,为后续工作提供必要参考。
In this paper,the main interference sources and coupling modes of substations are taken as the starting point,Research on grounding mode of shielding layer of two cable in substation protection,Discussion on the anti-interference effect of shielding layer,On the basis of this,The different ways of shielding grounding are analyzed emphatically,Provide the necessary reference for the follow-up work.
