A kind of oil-filled transformer heat abstractor
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.

Embodiment
Please refer to Fig. 2 and shown in Figure 3, Fig. 2 is the vertical view of the utility model embodiment oil-filled transformer heat abstractor, and Fig. 3 is the profile of the utility model embodiment oil-filled transformer heat abstractor.
The utility model provides a kind of oil-filled transformer heat abstractor, in present embodiment, described oil-filled transformer heat abstractor comprises device body heater 1, its outer periphery is equipped with hollow radiating fin 2, filling heat-conductive oil 3 between described hollow radiating fin 2 and the device body heater 1, and be provided with warm field separator 4 between described device body heater 1 and the hollow radiating fin 2, described temperature field separator 4 hollow radiating fin 2 setting that reclines, and the upper and lower side in hollow radiating fin 2 leaves upper oil hole 5 and following oilhole 6, high temperature heat conductive oil rises to upper oil hole 5 along warm field separator 4, flow into hollow radiating fin 2 from upper oil hole 5, after 2 heat radiations of hollow radiating fin, again from flowing out in the oilhole 6 down, described temperature field separator 4 all cuts horizontal and vertical temperature field and tells road up and down, oil stream heat power is increased, and radiating efficiency significantly promotes, and can improve radiating efficiency 10%~20%.
The utility model provides a kind of oil-filled transformer heat abstractor, described oil-filled transformer heat abstractor is provided with warm field separator 4 between device body heater 1 and hollow radiating fin 2, 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.
Fig. 3 is the profile of the utility model embodiment oil-filled transformer heat abstractor; but a kind of oil-filled transformer heat abstractor of the utility model tool is not limited to arrangement mode and this a kind of shape of this a kind of assembly; as shown in Figure 3; satisfying on the basis of its function; can change along with the change that the position is set of warm field separator; the change that anyone makes arrangements of components mode of the present utility model, model and shape on principle of the present utility model basis has easily then all fallen into protection range of the present utility model.
