一、医用诊断X射线辐射源检定中的常见问题1.电源指示灯不亮,电源电压表无读数(1)电源闸所设保险丝接触不良、熔断或无交流电。(2)电源电缆插头(座)松动或电缆芯线断。(3)控制台上电源保险丝接触不良或熔断。(4)电源电压调节器接触不良或引线脱落。2.X射线管的电压不合格对一个电压检定点,要在不同的管电流下进行测量,以检验其内阻补偿,以便客观准确评价这项指标。影响管电压的主要有电压表准确度、管球真空度降
First, the medical diagnosis of X-ray radiation source in the test of the common problems 1. Power indicator is not lit, the power supply voltage meter without reading (1) power supply gate set fuse contacts, fuse or no AC. (2) Power cable plug (seat) loose or broken cable core. (3) The power fuse on the console is not in good contact or blown. (4) The power voltage regulator is not in good contact or the lead is disconnected. 2. X-ray tube voltage failure on a voltage test point, to be measured at different tube current to test the resistance compensation in order to objectively and accurately evaluate this indicator. Mainly affect the tube voltage voltmeter accuracy, tube vacuum drop
