故障现象：该机不定期爆透视保险ＲＤ３（１０），提高ｋＶ后更易爆，而摄影正常。从现象分析故障大致在高压发生器、高压电缆和球管。首先检查高压发生器和高压电缆，把透视阴极电缆从球管套中拔出后悬空，在高压箱的Ｐ１接线卡上电流钳。机器通电，ｋＶ由低至高进行曝光监测
Symptom: This machine does not regularly burst perspective insurance RD3 (10), after raising kV more explosive, and photography is normal. From the phenomenon of fault analysis roughly in the high-voltage generator, high-voltage cables and tube. First check the high-voltage generator and high-voltage cable, the perspective of the cathode cable pulled out from the ball socket after the dangling, P1 in the high-voltage box on the current clamp clamp. The machine is energized and kV is monitored from low to high exposure
