摘要
电力变压器的安全可靠运行运行对整个电网的意义极其重大。然而由于受到短路电流冲击等各种因素的影响,变压器绕组可能发生变形,不易被发现。通过对目前变压器绕组变形检测的研究现状的介绍,分析了变压器绕组变形监测的几种方法及其优缺点。
The safe and reliable operation of Power transformer plays significant role on Power network safety. Due to the impact of short circuit current, deformation of its windings would happen, and the winding deformation is always not easy to be detected. Here the present methods of winding deformation detection and monitoring are introduced. Their advartages and shortages are compared in detail.
