摘　　要：介绍某变电站2号主变压器发生低压出线短路后造成主变压器绕组烧毁的故障,采用变压器频响法、绕组电容量分解法、低电压短路阻抗法分析故障原因,认为主变压器低压侧抵御短路能力不足,绝缘薄弱是造成此次故障的主要原因,并提出相应的防范措施及建议。The article introduces a transformer substation No.2main transformer in low voltage wire short circuit after the main transformer winding burned problem,from the transformer high voltage electrical test data and oil test analysis,thought a transformer substation No.2main transformer low voltage side against short circuit capacity is insufficient,weak insulation,short circuit capacity is not enough reason,put forward the corresponding treatment measures and Suggestions.
