A transformer oil return port 2 connected to the oil cavity is opened at the upper end of the transformer body 1. A transformer oil outlet 7 connected to the oil cavity is opened at the right end of the transformer body 1. The transformer oil return port 2 is connected with the heat exchange oil outlet 8 through a pipeline, and the transformer oil outlet 7 is connected with the heat exchange oil inlet 14 through a pipeline.

The working principle of the utility model;

The transformer oil inside the transformer body 1 flows through the transformer oil outlet, the transformer oil outlet 7 and the heat exchange oil inlet 14 into the heat exchange shell 9. The transformer oil entering the heat exchange shell 9 flows through the lower diverter plate 13 and the surface of the heat exchanger 12. After the transformer oil passes through the surface of the heat exchanger 12, the heat in the transformer oil is converted to the circulating water inside the heat exchanger 12 through the heat exchanger 12. The transformer oil after absorbing the heat enters the oil inlet of the circulating oil pump 10 through the upper guide plate 11. The circulating oil pump 10 operates to extract the transformer oil after heat exchange through the oil inlet of the circulating oil pump, and enters the transformer body 1 through the heat exchange oil outlet 8 and the transformer oil return port 2. The water inlet and water outlet of the heat exchanger 12 The outlet is connected to the phase change energy storage device 21 through a connecting water pipe, and the circulating water flows into the heat exchanger 12 through the water inlet of the heat exchanger 12. The circulating water absorbs the converted heat of the transformer oil through the heat exchanger 12 to cool the transformer oil. The circulating water after absorbing the heat flows into the phase change energy storage device 21 through the water outlet of the heat exchanger 12. The circulating water after absorbing the heat converts the heat to the phase change energy storage material inside the phase change energy storage device 21, and the transformer heat is stored through the phase change energy storage material. The stored heat is then transported to where it is needed to improve energy utilization. The water pump inside the phase change energy storage device 21 draws the circulating water after the heat exchange is completed into the heat exchanger 12 to absorb heat, and the cycle is repeated.
