Problems solved by technology

Generally, the manufacturer meets the requirements of reducing the temperature rise of the transformer by enlarging the cooling oil channel of the coil and increasing the cross-sectional area of ​​the electromagnetic wire in the design. The increase of the cooling oil channel of the coil and the increase of the cross-sectional area of ​​the electromagnetic wire mean that The iron core weight and electromagnetic wire weight of the 10kV oil-immersed transformer are increased, the production materials such as the iron core, wire rod, and transformer oil are wasted, the production cost of the 10kV oil-immersed transformer is increased, and the no-load loss of the 10kV oil-immersed transformer is also increased.

Abstract

The invention discloses a 10kV oil-immersed transformer water cooling device. The 10kV oil-immersed transformer water cooling device comprises a transformer open oil tank and an oil tank cover for closing the transformer open oil tank, wherein a water cooling device for cooling the 10kV oil-immersed transformer is installed on the bottom of the oil tank cover; two end parts of a rectangular seamless stainless steel pipe formed in a bending manner of the water cooling device respectively penetrate through the top surface of the oil tank cover and are fixed on the oil tank cover by virtue of a sealing device. By adopting the 10kV oil-immersed transformer water cooling device, the temperature rising requirement of the 10kV oil-immersed transformer is met, compared with the existing 10kV oil-immersed transformer, consumption of production materials such as iron cores, wire stock, transformer oil and the like is reduced, and the idle loss of the 10kV oil-immersed transformer is also prevented; the leakage of oil in the transformer and cooling water in the rectangular seamless stainless steel pipe of the 10kV oil-immersed transformer oil tank is also prevented.

Description

technical field [0001] The invention belongs to a 10KV oil-immersed transformer cooling device, in particular to a 10KV oil-immersed transformer water cooling device. Background technique [0002] At present, the national standard GB1094 requires that the structure of a 10kV oil-immersed transformer is that the transformer body and internal leads are immersed in transformer oil, and the transformer oil plays the role of insulation, arc extinguishing and heat dissipation. Generally, the manufacturer meets the requirements of reducing the temperature rise of the transformer by increasing the heat dissipation oil passage of the coil and increasing the cross-sectional area of ​​the electromagnetic wire in the design. The increase of the heat dissipation oil passage of the coil and the increase of the cross-sectional area of ​​the electromagnetic wire are The iron core weight and electromagnetic wire weight of the 10kV oil-immersed transformer are increased, the production materi...
