例一、故障现象:当S_2为上球管位,按下电源“通”按钮S_1时控制台得电,旋转阳极不受摄影准备继申器PBR控制,旋转阳极自行运转,球管壳带电。检修方法与程序:按照检修机器步骤,把高压初级接线P_1P_2拆下,将PC平床电源线及滤线器、聚光器电源线全部拆下,机器得电故障仍然存在,分析故障现象为线圈与球管壳短路。将电缆拔出,取下球管,打开管窗,倒出
Example 1 Symptom: When S_2 is the upper tube position, when the power button S_1 is pressed, the console is powered. The rotating anode is not controlled by the PBR of the photographic preparation relay. The rotating anode operates on its own and the bulb shell is electrified. Maintenance methods and procedures: In accordance with the maintenance machine steps, the high voltage primary wiring P_1P_2 removed, the PC flat bed power cord and filter, condenser power cord removed, the machine is still power failure, the analysis of the phenomenon of the coil and Shell short circuit. Pull out the cable, remove the tube, open the tube window, pour out
