在立式直流电源屏安装与调试过程中，监控模块发生告警的现象属于该过程中正常现象。以下针对直流屏充电模块保护的故障进行具体分析并提出处理方法。 A、充电保护模块的故障分析与处理 1、充电模块交流输入过电压、欠电压、缺相、过温将导致充电模块保护，请根据故障代码进行确认。 2、机柜装有玻璃门或者机柜密不透风，可能导致充电模块过热保护。 3、机房环境温度过高，也将导致充电模块过热保护。 4、充电模块故障。 5、充电模块的输出电压过高或者输出过流将导致模块故障，要求将模块断开交流后重新启动，可恢复模块正常。 6、在手动工作状态下时，输出过压告警值默认为242V，所有不合理的电压调整可能导致模块充电模块输出过压报警，该情况下重新调整模块的输出电压在正常范围内即可。 7、在自动工作状态是，模块的输出电压受上位机的控制，如果此时有监控，可能输出电压与实际设定值不一样，这是由于温度补偿功能造成的，属正常现象。
