该电源分为灯丝加热、高压直流、稳流主回路及高压触发四个部分组成。故障现象:氢灯不工作。分析与检修:开启氢灯电源,电源指示灯亮,氢灯不亮。按下“N”标记之圆钮,氢灯仍不起辉,电流表也无指示。打开机器检查氢灯灯丝完好。接通电源测量氢灯灯丝无10V 加热电压,怀疑灯丝电压控制可控硅D406坏。经测量可控硅完好。再测量可控
The power is divided into filament heating, high voltage DC, steady flow of the main circuit and high voltage trigger four parts. Symptoms: hydrogen lamp does not work. Analysis and Maintenance: Turn on the hydrogen lamp power, power indicator light, hydrogen light does not shine. Press the “N” mark round button, the hydrogen lamp is still not shiny, ammeter no instructions. Open the machine to check the hydrogen lamp filament intact. Turn on the power to measure the hydrogen lamp filament without 10V heating voltage, suspected filament voltage control silicon D406 bad. After measuring silicon intact. Measurable again
