故障现象 1:摄片时,照片密度明显减低,表现为X线的穿透力不够,用表测量高压初级电压较正常为低。故障原因:主可控硅SR_1和SR_2没有完全导通, 检测方法:按图1虚线框内所示,接一检测电
Symptom 1: When the picture is taken, the picture density is significantly reduced. The X-ray penetrating power is not enough. The primary voltage measured by the meter is lower than normal. Fault reason: The main thyristors SR_1 and SR_2 are not completely turned on. Detection method: as shown in the dashed line in Fig. 1
