大型水轮发电机定子线棒接头焊接,通常采用锡焊,虽易于施工,但机械强度差,允许电流密度小,而且容易发生开焊事故。广西电力试验所与广西水电工程局安装处共同在大化一号机(十万千瓦)上,试验摸索出一套板式结构的银磷铜钎焊接工艺。制定了“大化电站发电机组定子线棒接头银焊工艺守则”,同时采用外观检查,测量直流电阻和超声波检测三结合的测试方法,较准确
Large hydrogenerator stator bar connector welding, usually by soldering, although easy to construct, but the mechanical strength is poor, allowing the current density is small, but also prone to open welding accident. Guangxi Electric Power Test Institute and Guangxi Hydropower Engineering Bureau jointly installed in Dahua No. 1 machine (one hundred kilowatts), the trial explored a plate structure of silver phosphor bronze brazing process. Developed “Dahua Hydropower Station generator stator bar connector silver welding process code,” while the appearance of inspection, measurement of DC resistance and ultrasonic testing of three combinations of test methods, more accurate
