摘　　要：基于高寒地区冬季低温气候特征,实地调查研究电力变压器故障及缺陷状况。结合电力变压器工作环境和物理力学性能变化,分析了高寒地区电力变压器故障原因,提出运行维护的对策。可为高寒地区电力变压器的选型、试验及运行维护提供参考。Based on the climate characteristics of low temperature in winter in alpine region, field investigation and research is made on the failure and defects of power transformer. Combined with the change of power transformer＇ s working environment and physical and mechanical properties, failure reasons of transformer in alpine region are analyzed and the countermeasures of operation and maintenance of power transformers are put forward. Thus, that can provide a reference for the selection, testing and operation and maintenance in power transformers in alpine re- gions.
