摘　　要：现代化生产对供电可靠性要求越来越高,对具备两回线及以上的多回供电线路,安装母联备自投装置来提供可靠性。当一路电源出现问题时,母联备自投装置动作,保障电力稳定。当母联备自投装置出现逻辑错误时,就会引发备自投装置的拒动或误动,以实际故障来说明逻辑错误的危害及改进措施。the reliability of power supply is more and more demanding in modem production.Reliability is provided for multiple circuit power supply lines with two lines and above.When a power supply has problems, the parent is equipped with a self-switching device to ensure the stability of the power.When there is a logic error in the automatic switching device, it will cause the refusal or misoperation of the standby auto switching device.In this paper, we will illustrate the harm and improvement measures of the logic errors based on actual failures.
