在X线机直流高压发生器的设备中,有两根高压电缆一端插在高压发生器的电缆插座上,还有一端根据阴、阳极性分别插在x线管套的“+”“-”插座里,藉此使高压变压器两端的高电压加在X线管的阴、阳极上。然而有一部分机器由于使用年限过久,往往出现高压电缆芯线内部断裂或者内阻增大等情况,影响X线机的正常工作。作者曾利用原高压电缆的互换,迅速地使X线机恢复工作,现将具体做法简介如下: 1.直流高压发生器高压阴极电缆担负双重任务,一是传输高电压;二是供给大、小焦点灯丝加热电压。因此只要有一根芯线断裂,起码会有一组灯丝不能加热,如果恰好断在公用芯线上,那么两组灯丝就都不能
In the X-ray machine DC high voltage generator equipment, there are two high-voltage cables, one end is inserted in the cable socket of the high-voltage generator, and one end is inserted in the x-line tube sleeve “+” “-” In the socket, the high voltage across the high voltage transformer is applied to the cathode and anode of the X-ray tube. However, due to the long service life of some of the machines, there are often situations such as internal rupture of the high-voltage cable core or increased internal resistance, affecting the normal operation of the X-ray machine. The author once used the exchange of the original high-voltage cable to quickly restore the X-ray machine. The current practice is described as follows: 1. The DC high-voltage generator high-voltage cathode cable is responsible for two tasks, one is to transfer high voltage; the other is to supply large, Small focus filament heating voltage. Therefore, as long as there is a broken core wire, at least one set of filaments cannot be heated. If it happens to be broken on the common core wire, then both sets of filaments cannot
