Abstract
The utility model discloses a full-casting dry type transformer with the cooling top. The full-casting dry type transformer with the cooling top comprises an iron core, a coil and insulating resin; the top of the iron core is provided with silicone grease which is utilized as a cooling medium; an aluminum alloy casing wraps the outer side of the silicone grease; the surface of the aluminum alloy casing is provided with cooling fins. According to the full-casting dry type transformer with the cooling top, the insulating silicone grease is utilized as the cooling medium to be distributed at the top of the iron core and cooling is performed through the cooling fins, so that the cooling effect is good, the temperature rise of the transformer is reduced, and the service life of the transformer is long.
Description
Technical field
The utility model relates to a kind of heat radiation of transformer, specifically a kind of full casting dry type transformer of top heat dissipation.
Background technology
Along with the development of national economy all trades and professions, the electric unit of using of various power modes has appearred in China.The distribution transformer of industries such as some steel mill, Metallurgical Factory must be placed in the narrower and small device space, so to the overall dimension of distribution transformer, require very strict.In order to reduce transformer overall dimension, full casting dry type transformer has appearred on market now, between this transformer high-low-voltage, between low pressure and iron core, casting resin is all adopted in all insulation, thus the insulation distance of coil can be reduced, thus reduced transformer overall dimension.But full cast transformer, owing to there is no the mobility heat eliminating medium, causes the transformer radiating effect bad, has increased the transformer temperature rise, has reduced transformer life.
Summary of the invention
In order to improve the radiating effect of full casting dry type transformer, the purpose of this utility model is to provide a kind of full casting dry type transformer of top heat dissipation, the silicone grease of this transformer utilization insulation is arranged in the iron core top as heat eliminating medium, and by fin, dispel the heat, good heat dissipation effect, reduced the transformer temperature rise, the transformer long service life.
The purpose of this utility model is achieved through the following technical solutions:
A kind of full casting dry type transformer of top heat dissipation, comprise iron core, coil and insulating resin, it is characterized in that: be provided with the silicone grease as heat eliminating medium at the iron core top, in the silicone grease outside, be enclosed with aluminum alloy casing, on the aluminum alloy casing surface, fin is set.
In the utility model, described silicone grease is arranged the top of full whole iron core.Fin is arranged on the top of aluminum alloy casing.
The silicone grease that the utility model will insulate is arranged full iron core top as heat eliminating medium, wrap up with aluminum alloy casing, dispel the heat at shell surface soldered fin, the heat that transformer produces conducts to silicone grease by the iron core top, silicone grease conducts heat to fin again, and fin arrives air with dissipation of heat again, can effectively reduce the iron core temperature like this, thereby reduce the transformer temperature rise, extended transformer useful life.
The utility model has the advantages that:
1. be elected to be the iron core top heat dissipation, be in the center of transformer due to iron core, bad distributing after heat generation, be the most important thing so select the temperature of reduction iron core; Iron core good heat conductivity besides, whole transformer heat can pass through iron core heat conduction distribute heat.
2. select silicone grease as heat eliminating medium.Silicone grease is insulating material, prevents multipoint earthing of iron core.The silicone grease heat conductivility is reasonable in insulating material, and character is softer, with iron core, contacts well.
3. case surface welding aluminum alloy fin, make radiating effect reach best.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is profile schematic diagram of the present utility model.
Embodiment
A kind of full casting dry type transformer of top heat dissipation, see Fig. 1 and Fig. 2, and this transformer comprises iron core 1, coil 2 and insulating resin 3, is provided with the silicone grease 4 of while as heat eliminating medium and insulating material at the iron core top, and silicone grease is arranged the top of full whole iron core.Be enclosed with aluminum alloy casing 5 in the silicone grease outside, on aluminum alloy casing 5 surfaces, fin 6 be set, fin also is arranged on the top of aluminum alloy casing.
The utility model wraps up with aluminum alloy casing, at shell surface soldered fin, dispels the heat, and the heat that transformer produces conducts to silicone grease by the iron core top, silicone grease conducts heat to fin again, fin arrives air with dissipation of heat again, reduces the iron core problem, thereby reduces the transformer temperature rise.
