在大中型X线机中,高压发生器和X线管是分立的部件,高压电缆是供给X线管直流高压所必需的特制导线,由于高压电缆随X线管管套使用时需要经常移动和弯曲,容易造成裂缝进气,使绝缘度下降造成断路或短路击穿,短路击穿通常用肉眼或用嗅觉可把击穿部位找出来,但若芯线断路,有些电缆长2
In large and medium-sized X-ray machines, the high-voltage generator and the X-ray tube are separate components. The high-voltage cable is a special wire necessary for supplying the X-ray tube with high DC voltage. The high-voltage cable needs to be moved frequently when used with the X-ray tube sleeve. Bending can easily cause cracks to enter the air, causing a decrease in the degree of insulation to cause an open circuit or a short circuit breakdown. Short circuit breakdowns are usually found with the naked eye or with the sense of smell. However, if the core wire is broken, some of the cables are long.
