摘要
本文以某变电所一次对二次干扰的实例,分析了使用隔离开关操作母线所引起的电压、电流的暂态过程。提出了由此产生的高频暂态电流经电容式电压互感器流入地网,从而由二次接地引线暂态波阻抗引起干扰过电压的理论。
Based on the example of interference in protection system caused by power line the paper analyses the transient process by bus-disconnect switching and discribes the theory that the HF transient current produced during switching flows into the earthing nets through the CVT and the interference over-voltage is produced on the earthing wrie of the protect system.
