故障现象扫描突然中断 ,监视器提示“Ｘ２２Ｘ -ＲＡＹＥＲＲＯＲ”。查阅技术资料 ,Ｘ２２代码提示为主电路的高压初级异常。观察高压柜上方面板的故障指示灯 ,发现过流指示灯ＯＣＩＮＶ３亮。故障分析与检修日立Ｗ５５０型ＣＴ机高压初级端的电路原理为 :电源稳压后经整流平
Symptom Scan suddenly interrupted, the monitor prompts “X22X -RAYERROR.” Access to technical information, X22 code prompts the main high-voltage primary abnormalities. Observe the fault indicator on the panel above the high voltage cabinet and find that the overcurrent indicator OCINV3 is on. Failure Analysis and Overhaul Hitachi W550 CT high-voltage circuit at the primary side of the circuit is: regulated by the power regulator
