法国 CGR500mAX 线机是一种双床双旋转阳极球管、可控制投闸式的大型 X 线机。全套设备引进后我们用日本东芝影像增强电视系统与其配套,总价值22万元。该机投入使用后不久,连续发生几起故障,在排除这些故障时,开始是采取对症处理法,坏了哪里修哪里,结果修好一次运行几天又出现故障。后来我们运用联想法检修,终于彻底查清了造成几起故障的共同原因。现介绍如下。故障现象透视高压继电器 S_(06)(?)工作,但不出线。测量高压初级022、023无电压,说明故障发生在高压初级电路。仔细检查发现与 S_(06)(?)接点串接的透视突波电阻 R_(02)(2.2 France CGR500mAX line machine is a double bed double rotating anode tube, can control the type of large X-ray machine. After the introduction of a full set of equipment, we use the Japanese Toshiba video enhanced TV system and its supporting, the total value of 220,000 yuan. Shortly after the aircraft was put into use, several failures occurred in a row. When these faults were eliminated, the initial treatment was symptomatic treatment, where the repair was broken, and the result was repaired. Later, we use the Lenovo method of repair, and finally completely find out the common cause of several failures. Now introduced as follows. Failure phenomenon Perspective high-voltage relay S_ (06) (?) Work, but not out of line. Measuring high voltage 022,023 no voltage, indicating that the fault occurred in the high voltage primary circuit. Carefully examine the see-through surge resistor R_ (02) (2.2
