在大多数X线机中自耦变压器为整机提供电源,并起调节KV的作用,一旦它发生故障,X线机就不能正常工作。自耦变压器经常会发生的故障是碳轮与漆包线表面接触不良而打火花,或匝间短路,引起局部过热而烧焦漆包线和绝缘纸筒。修理的办法可以是将自耦变压器从控制台内拆出,把碳轮两端支架和碳轮滑杆拆下,卸去铁芯固定螺栓将铁芯硅钢片从一端逐片抽出存放好。然后捧住线圈从架上取出,放
In most X-ray machines, the autotransformer provides power to the complete machine and acts to adjust the KV. Once it fails, the X-ray machine will not work properly. Frequent failures of the autotransformer are poor contact between the carbon wheel and the enameled wire, sparking, or short circuit between the turns, causing local overheating and burning of the enameled wire and the insulating paper drum. The repair method may be to remove the autotransformer from the console, remove the carbon wheel end supports and the carbon wheel slide bar, and remove the iron core fixing bolts to extract the iron core silicon steel sheet one by one from the end and store it. Then hold the coil out of the rack and put it
