摘要
分析了电力系统Y/△-11联接组别变压器两侧发生两相非金属性短路时,当故障点过渡电阻R由0变化到∞时,故障点以及保护安装处的各相电压、电流的变化规律及特点,由此分析出变压器各相电流保护接线的功率方向继电器的动作情况。
This article describes when two-phase non-metal short circuit of both sides of power system Y/△-11 connection type transformer occurs and transition resistance of failure point varies from zero to ∞, failure point and protection location each phase voltage and current variation regular and character, it presents further more analysis transformer each current protection wire power direction relay operation.
