变压器强迫油循环水冷系统事故简析

主变压器是变电站最重要的设备之一,其运行的稳定性决定了变电站的正常运行。目前,大型变压器大多采用风冷、水冷等方式,地下变电站的主变压器主要采用了强迫油循环水冷却的冷却方式,文章简析了地下变电站某次变压器强迫油循环水冷系统事故的过程、原因,并提出优化改造建议,对今后强迫油循环水冷系统运行维护、设计改造有重要意义。

The main transformer is one of the most important equipment in the substation,and its operation stability determines the normal operation of the substation.at present,most of the large transformers are air-cooled,water-cooled and so on.The main transformer of underground substation mainly adopts the cooling mode of forced oil circulating water cooling.this paper briefly analyzes the process and causes of a transformer forced oil circulating water cooling system accident in underground substation,and puts forward some suggestions for optimization and transformation.It is of great significance to the operation,maintenance,design and transformation of forced oil circulating water cooling system in the future.
