220kV母线保护TV断线闭锁功能检验()A、电压反相序的TV断线:在母线电压回路中加入负序的对称三相电压57.7V,TV断线报警可靠动作B、电压回路单相断线的TV断线:在母线电压回路中加入正序的对称三相电压57.7V,断开一相电压,TV断线报警可靠动作C、电压回路三相断线的TV断线:在母线上的任意支路加入三相对称的正序电流,该母线的TV断线报警可靠动作D、A+B+C
考题
RCS-901(2)A装置中,如果三相电压向量和小于8伏,而且正序电压小于0.5Un,若采用母线TV则延时1.25秒报TV断线;若采用线路TV,则当但任一相有电流动作或TWJ不动作时,延时1.26秒报断线异常信号。通过控制字来确定是采用母线TV还是线路TV。
考题
