XG-500型 X 线机。设有冷压保护装置,即当灯丝电路出现断路时,灯丝不亮,冷压保护继电器 LBJ 不工作,使曝光不能进行,这就避免冷高压对 X 线管形成危害,延长 X 线管的使用寿命。但现在生产的本型号X 线机冷压保护装置在胃肠摄影时不起作用,胃肠摄影灯丝是大焦点,那么,如果灯丝不亮,X 线管两端加上高压,无疑对 X 线管仍存在危害。我科经对过载保护电路进行了改进,实现了对胃肠摄影进行冷压保
XG-500 X-ray machine. With a cold pressure protection device, that is, when the filament circuit is open circuit, the filament is not bright, cold pressure protection relay LBJ does not work, the exposure can not be carried out, which avoids the cold high pressure on the X-ray tube to form a hazard to extend the use of X-ray tube life. But now the production of this model X-ray cold pressure protection device does not work in gastrointestinal photography, gastrointestinal photography filament is a big focal point, then, if the filament is not bright, X-tube with high pressure at both ends, no doubt on the X-ray Tubes are still dangerous. Our section of the overload protection circuit has been improved to achieve a cold gastrointestinal photography insurance Paul
