故障现象１开机工作一段时间后 ,面板过载指示灯亮。分析维修检查机器ｋＶ、ｍＡ、ｓ皆在工作范围以内。检查三相输入电源４３０Ｖ ,超过正常电压３８０Ｖ ,查电源手册 ,工作电压３８０±５ % ,约在３６０Ｖ～４００Ｖ之间 ,而实际电压在４３０Ｖ ,故造成电压过载。因为我院引
Symptom 1 After power on for a period of time, the panel overload indicator lights up. Analyze the maintenance inspection machine kV, mA, s are within the working range. Check the three-phase input power supply 430V, exceed the normal voltage 380V, check the power supply manual, working voltage 380 ± 5%, about 360V ~ 400V, and the actual voltage is 430V, it causes voltage overload. Because of my hospital cited
