一、前言水轮发电机静子线圈接头,往往由于焊接质量不良,运行中逐渐恶化,如不及时发现和处理,就会造成开焊事故,烧损电机,给电力安全生产带来很大危害。因此,保证电机静子直流电流不超过规定值,监视其接头,使之处于良好状态下运行,是我们电业检修人员的一项重要工作。如何用非破坏性的方法,准确而又简便的探测出发电机静子接头的故障,是当前国内电气工作者的一个研究课题。我厂高压班的同志,遵照毛主席关于“实践第一”的教导,学习国内有关先进经验,领导干部、工人、技术人员三结合,经过反复试验,克服了很多困 First, the foreword Turbine stator coil connector, often due to poor quality welding, running deteriorating, if not found and handled, it will cause a welding accident, burning motor, to the safety of electricity to bring great harm. Therefore, to ensure that the motor stator DC current does not exceed the specified value, monitoring its joints, so that it operates in good condition, is our electrical maintenance personnel an important task. How to use the non-destructive method to detect the fault of the stator stator connector accurately and simply is a research subject of the current domestic electrical workers. Our high-voltage class comrades, in conformity with Chairman Mao’s teachings of “practicing first”, have learned from the combination of the relevant advanced experiences, leading cadres, workers and technicians in the country. After repeated tests, they have overcome many difficulties
