摘要
提出了一种220 kV失压闭锁继电器线路改进方案。介绍了RXBA4继电器结构和工作原理,比较了两种接线方式,指出接入电压U1、U2应分别取自两组PT。该改进方案对RXBA4继电器的正确使用有参考意义。
An improvement scheme of 220 kV voltage loss blocking circuit was proposed. The structure and principle of RXBA4 relay were introdued. Two ways of connection mode were compared. That accessing voltage U1 ,U2 were respectively got from two groups of PT. That scheme has reference meaning for how to correctly use RXBA4 relay.
