东方红 F_(30)-ⅡB 和 F_(30)-IC 型,新华 F200型、扬州YZ100型 X 线机限时器中,所用 JH-1E 极化继电器线圈的线径只有0.06毫米,易断。尤其是当12-13绕组线圈断路后,会发生曝光时间无限延长,导致 X 线管超负荷而损坏。为了防止发生这类故障,我们对这种极化继电器进行了改绕。方法是这样:将原有线圈全部拆掉,12-13间改用线径0.11毫米漆包线于内层绕2500匝;1、2
The red line F_(30)-IIB and F_(30)-IC type of Dongfanghong, Xinhua F200 and Yangzhou YZ100 X-ray machine time limiters, the wire diameter of JH-1E polarization relay coil used is only 0.06mm, and it is easy to break. In particular, when the 12-13 winding coil is disconnected, the exposure time will be infinitely extended, causing the X-ray tube to be overloaded and damaged. In order to prevent such failures, we have modified this polarization relay. The method is as follows: remove all the original coils, and change the diameter of the 0.1-13 mm enameled wire from 12-13 to 2500 turns in the inner layer; 1,2
