| 常规预防性试验项目，对查找水轮发电机定子绕组端部绝缘缺陷的具体位置存在一定的难度。本文结合具体的案例，通过借鉴汽轮机绕组电位外移的试验方法，找到了水轮发电机定子绕组存在绝缘缺陷的具体部位，成功解决了定子绕组三相泄漏电流不平衡的问题，验证了水轮发电机定子绕组表面电位测试的可行性及其具有的优点。 |
| 英文摘要: |
| The conventional preventive test project is di?cult to and the specirc location of the insulation defect at the end of the stator winding of the hydro generator. In this paper, a concrete case is used to and out the specirc parts of the insulation defect in the stator winding of the turbine generator, and the problem of the unbalanced leakage current of the stator winding is solved successfully. The feasibility of the potential test of the stator winding surface of the turbine generator is vericed and the feasibility of the test is vericed and have the advantages. |
