摘要
详细地介绍了大型汽轮发电机定子线棒与铁心槽壁存在间隙引起火花放电产生电腐蚀的原理,以及利用夹紧系数试验诊断定子线圈与铁心槽壁间隙的方法及原理。
The principle of electro-etching produced as a result of spark-over arising due to the clearance between stator bar and core slot wall for large turbinegenerator is described in detail, as well as the method and principle of diagnosing the clearance between stator bar and core slot wall by clamping coefficienet test are introduced also in this paper.
