Abstract
The utility model relates a radiating device of an oil-immersed transformer. The radiating device of the oil-immersed transformer comprises a transformer body heating element; a hollow radiating fin is arranged at the periphery of the transformer body heating element; a temperature field baffle plate is arranged between the transformer body heating element and the hollow radiating fin; the temperature field baffle plate leans against the hollow radiating fin; an upper oil hole and a lower oil hole are formed at the upper end and at the lower end of the hollow radiating fin; the temperature field baffle plate is arranged between the transformer body heating element and the hollow radiating fin of the radiating device of the oil-immersed transformer, and an upper channel and a lower channel are cut off on the transversal and longitudinal temperature fields; therefore, the oil-flow thermal power is increased, and the radiating efficiency is improved to a much greater extent; moreover, the utility model has the advantages of simple structure, safety, reliability and excellent radiating performance.
Description
Technical field
The utility model relates to a kind of heat dissipating device of transformer, particularly relates to a kind of heat abstractor of oil-filled transformer efficiently.
Background technology
Transformer is the main and important components of power supply changeover device, it is in the process of operation, because the existence of the mobile and electromagnetic field of each coil-conductor electric current, can produce electric energy loss, it mainly is load loss, no-load loss and supplementary load loss, these losses will be converted into the heat transferred surrounding medium, thereby make the device body heating of transformer, temperature raises, therefore for transformer, heat abstractor often to be set the electric energy loss heat is in time shed, to guarantee the operate as normal of transformer as the power transmission and transformation substantial equipment.
See also shown in Figure 1, Fig. 1 is the profile of traditional oil immersed type heat dissipating device of transformer, as shown in Figure 1, traditional oil-filled transformer heat abstractor comprises device body heater 1, the periphery of described device body heater 1 evenly is provided with most hollow radiating fins 2, filling heat-conductive oil 3 between described hollow radiating fin 2 and the device body heater 1, rely on the heat radiation power of heat buoyancy as conduction oil 3, utilize the motion of conduction oil 3 to dispel the heat, but the heat abstractor of this structure is in conduction oil 3 motion processes, because two not well-proportioned natural temperature field effects of being interweaved up and down, the motion of described conduction oil 3 is very disorderly, causes radiating effect very poor.
Be directed to above-mentioned situation, be necessary to provide a kind of oil-filled transformer heat abstractor in fact, described oil-filled transformer heat abstractor is not only simple in structure, and safe and reliable, good heat dispersion is arranged, to overcome the defective of oil-filled transformer heat abstractor in the prior art.
The utility model content
The purpose of this utility model is to provide a kind of oil-filled transformer heat abstractor, and described oil-filled transformer heat abstractor is not only simple in structure, and safe and reliable, and good heat dispersion is arranged.
For reaching above-mentioned purpose, the utility model provides a kind of oil-filled transformer heat abstractor, and described oil-filled transformer heat abstractor comprises device body heater, and its outer periphery is equipped with the hollow radiating fin, wherein, be provided with warm field separator between described device body heater and the hollow radiating fin.
Especially, the hollow radiating fin setting that reclines of described temperature field separator, and leave upper and lower oilhole in the upper and lower side of hollow radiating fin.
Compared to prior art, the utility model provides a kind of oil-filled transformer heat abstractor, described oil-filled transformer heat abstractor is provided with warm field separator between device body heater and hollow radiating fin, horizontal and vertical temperature field all cut tell up and down road, not only simple in structure, and safe and reliable, good heat dispersion is arranged.
