故障现象摄片十几张后，感觉管套发烫，位置靠阳极端，其余无异常。故障分析与处理管套发烫但ＭＡ表正常，所以不存在高压放电这种情况，又因摄片正常，灯丝电压过高和千伏表偏高这两种情况也几乎不存在，所以最大的可能就是旋转阳极定子线圈经常处于得电状态，线圈发热导致管 Symptoms After more than a dozen photos, the sleeves feel hot and the position is on the anode side. The rest is not abnormal. Fault analysis and processing Sleeves are hot but the MA table is normal, so there is no such thing as high-voltage discharge, and because the radiography is normal, the filament voltage is too high and the kV meter is too high. These two conditions are almost nonexistent, so the largest It may be that the rotating anode stator coil is always in the electrified state, and the coil heats up the tube
