目前国产的小型X线机,包括移动式X线机(30—50毫安)和携带式X线机(10—15毫安),已在全国各基层卫生单位普遍装备,除机械结构较旧型号机器有较大改进外,并在高压初级线路中采用了逆电压衰减器,现将其工作原理作一简述: 小型X线机采用的是自整流高压线路,机器的X线管直接与高压变压器的次级输出端相连接,高 At present, domestic small X-ray machines, including mobile X-ray machines (30-50 milliamps) and portable X-ray machines (10-15 milliamps), have been widely equipped in all primary health units across the country. Model machines have greatly improved, and in the high-voltage primary circuit using a reverse voltage attenuator, now its working principle for a brief: Small X-ray machine is self-rectifying high-voltage lines, the machine directly and the X-ray tube High-voltage transformer secondary output phase connection, high
