摘要
通过对一台220 kV变压器绕组变形的测试和对比分析,总结了早期预警变压器遭受短路冲击后绕组变形状况的可能性,提出了预防性试验中通过电容量变化掌握绕组变形的初步方法和提高变压器抗短路能力的具体措施。
Through test and comparing analysis on a 220 kV transformer winding deformation,early-warning possibility for transformer winding deformation circumstance after suffering the short-circuit impact are summarized. It is put forward that the primary method of mastering winding deformation through the electric capacity variety,and the concrete measures to enhance resisting short circuit capability of transformer.
