计一、氘灯启辉稳流电路分析如图1所示:当电源开关K接通后,变压器B级的各级绕组同时得到电压,次级间绕组C和D之间的交流2.5V电压氘灯灯丝电压,这个电压通过继电常闭接点J1-5对氘灯灯丝预热。变器次级上绕组间的交流100V电,经整流滤波后,得到正140V电,此电压加在氘灯的阳极。变
A deuterium lamp Qihui steady flow circuit analysis shown in Figure 1: When the power switch K is turned on, the transformer B-level windings at all levels of voltage at the same time, the secondary winding between the AC and C 2.5V voltage Deuterium lamp filament voltage, the voltage through the relay normally closed contact J1-5 deuterium lamp filament preheat. AC secondary side of the transformer between the exchange of 100V electricity, the rectifier filter, get positive 140V electricity, the voltage added to the anode of the deuterium lamp. change
