故障现象 :开机进行摄影 ,继电器ＪＣ2、ＪＣ6、ＪＣ8吸合不下 ,无ｍＡ产生。 分析与检修 :关机后 ,打开控制台 ,拆下高压初级接线。开机后 ,进行曝光 ,发现继电器吸合不下 ,旋转阳极旋转 ,但速度比正常时慢 ,查旋转阳极保护电路。电源变压器Ｂ1的独立绕组产生的交流电压经
Symptoms: The camera is switched on and the relays JC2, JC6, JC8 do not pick up, no mA is generated. Analysis and Maintenance: After shutdown, open the console and remove the high-voltage primary wiring. After the start-up, exposure was performed and the relay was found to be unable to pull in and the rotating anode was rotating, but the speed was slower than normal. Check the rotating anode protection circuit. The AC voltage generated by the independent winding of the power transformer B1
