At the same time, the second pump body 305 is started, and the second pump body 305 is started. 05 will pump the water in the water tank 301 outward and send it into the cooler 303 through the second delivery pipe 304. The cooler 303 will cool the inflowing coolant when it is working. This part is an existing mature technology, and its principle is fully disclosed and will not be repeated here. The cooled coolant will flow back to the water tank 301 through the first delivery pipe 302, which plays a role in cooling the coolant in the water tank 301, and the oil in the second heat dissipation pipe 306 that has been fully cooled will flow back to the shell 1 through the drain pipe 307 and mix with the high-temperature insulating oil inside. In this reciprocating cycle, the insulating oil in the shell 1 can be quickly cooled in a short time to prevent the rectifier from The temperature of the transformer rises sharply in a short time, but cannot be cooled down quickly, which affects the use. The heat dissipation and cooling effect of the high-power rectifier transformer is improved. A measuring tube 309 is set on one side of the water tank 301.
