S11 35KV High Voltage Transformer For sale Oil-immersed transformer has the characteristics of good heat dissipation, low loss, large capacity and low price. At present, most of the power transformers operating on the power grid are oil-immersed transformers, of which more than 80% are cooled by natural oil circulation. The guide plate in the coil of natural oil circulation transformer is a kind of cooling structure which is widely used now. This paper focuses on the analysis of the structure, operation and maintenance of the oil-immersed power transformer, and specifically analyzes the oil system of the oil-immersed power transformer, and briefly analyzes the fault of the oil-immersed power transformer. Hope to increase the understanding and analysis of China's oil-immersed power transformers.
