[0002] In the power system, as key equipment, the stable operation of transformer is crucial to the safety and reliability of the entire power grid. With the continuous growth of power demand, the power level of transformer is also continuously improved, and higher thermal load follows. Traditional transformer cooling methods, such as natural air cooling or forced air cooling, have been difficult to meet the heat dissipation needs of high-power transformers. These traditional cooling methods have the disadvantages of low heat dissipation efficiency, high noise, high maintenance cost, and sensitivity to environmental temperature when dealing with high thermal load.

[0003] However, the existing water-cooled transformer heat dissipation device still has some problems in design and implementation, such as the complexity of the water cooling circuit, the risk of cooling water leakage, and the high requirements for water quality. These problems limit the widespread application of water-cooled transformer heat dissipation devices.

[0004] Therefore, based on the above technical problems, it is necessary for technicians in the field to develop a high-power water-cooled transformer heat dissipation device. SUMMARY

[0005] The utility model aims at providing a kind of high-power water-cooled transformer heat dissipation device to solve the problems raised in the above background.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0007] A high-power water-cooled transformer heat dissipation device technical scheme, comprising two groups of water-cooled aluminum shells, two groups of the water-cooled aluminum shells are provided with isolation insulating sheets, two groups of the water-cooled aluminum shells are respectively provided with transformer output end one and transformer output common end, the transformer output common end is provided with transformer output end two, and two groups of the water-cooled aluminum shells are respectively provided with transformer output end one and transformer output common end.

[0008] As a preferred technical scheme, the bottom of the water-cooled aluminum shell is provided with a cooling water inlet, the top of the water-cooled aluminum shell is provided with a cooling water outlet, the inside of the water-cooled aluminum shell is provided with a water cooling channel, the cooling water inlet is connected with the water cooling channel, and the cooling water outlet is connected with the water cooling channel.

[0009] As a preferred technical scheme, a plurality of waterway output plugs are arranged on the water cooling channel.

[0010] As a preferred technical solution, the isolation insulating sheet is used to isolate the electrical connection between the two groups of water-cooled aluminum shells, so as to ensure the safety and stability of the device under high current working state.

[0011] Compared with the prior art, the utility model has the advantages that:

[0012] The utility model discloses a high -power water -cooled transformer heat abstractor can effectively handle the high heat load of high -power transformer to improve the heat dissipation efficiency of whole device. Compared with traditional air cooling mode, the noise that water cooling system generates when operating is smaller, and the noise pollution of working environment is reduced. Water cooling system is not influenced by environmental temperature, and can keep stable heat dissipation performance under different temperature conditions. Since water cooling system has higher heat exchange efficiency, the recycling frequency of cooling water is more under the condition of reaching the same heat dissipation effect, thereby reducing maintenance cost. By setting isolation insulating sheet, the utility model can effectively isolate the electrical connection between the two groups of water-cooled aluminum shells, and ensure the safety and stability of the device under high current working state.
