摘要
文章介绍了预防变压器短路故障的措施,给出了变压器绕阻变形的三种检测方法,即频响法、低压短路阻抗法、电容测量法。同时提出了变压器短路后在状态检修过程中应采取的决策、检修项目确定以及修理方案。
The measures for preventing short circuit fault of transformer were introduced, and three kinds of detection method for transformer winding deformation were given, such as frequency response, short circuit impedance of low voltage and capacity measuring. At the same time, the decision adopted in condition-based maintenance and determination of overhaul items as well as repair scheme after transformer short circuit were put forward.
