变电站二次接地网研究

Study on Secondary Grounding Grid in Transformer Substation

本文重点针对变电站二次回路上产生电磁干扰,使接在二次回路上的继电保护装置误动作或遭受损坏的问题,就变电站内敷设独立的二次接地网进行研究。

This paper studies on laying independent secondary grounding grid in transformer substation,aiming at problem that electromagnetic interference generated in secondary circuit of transformer substation causes misoperation or suffering damage to protective relaying device which connects secondary circuit.
