| 摘 要： | 通过对220kV某变电站一起RCS-915AB型母差保护发TA断线信号进行分析,排除TA二次有断线的可能,利用倒闸操作判断出该站一次设备存在断开点,设备最终解体结果也印证了该推断的正确性,为今后类似的事件处理提供了借鉴。

| Abstract: | Through the analysis of a 220kV substation RCS-915AB bus differential protection issued TA disconnection signal , the possibility of TA secondary disconnection is ruled out , using switching operation to determine this substation primary equipment having disconnected points .The final results of the device disintegration verify the correctness of the proposed inference , to provide a reference for handling the sim-ilar event in future . |
