Abstract
The utility model relates to an electric power transformer, and particularly relates to a novel oil-immersed type transformer. The novel oil-immersed type transformer provided by the utility model comprises an oil tank, an iron core and a winding, wherein the iron core and the winding are immersed into the oil tank full of transformer oil together; an oil tank shell is a square or oval box which is made of a steel board, is provided with an opening on the upper face, and is sealed at the lower bottom; ripple sheets are arranged on the wall around the oil tank shell; an upper cover is arranged on the upper part of the oil tank shell; the upper cover is connected with the oil tank shell by using a bolt; a tower-shaped wiring post is arranged on the upper cover; and a mounting bracket is arranged at the bottom of the oil box shell. The oil-immersed type transformer provided by the utility model is characterized in that U-shaped heat radiation pipes are arranged on the ripple sheets on the front wall and the back wall of the oil tank shell; and the U-shaped heat radiation pipes are communicated with the inner cavity of the oil tank shell. The oil-immersed type transformer provided by the utility model is novel in design, and integrates the heat radiation advantages of the oil-immersed type transformer provided with the heat radiation pipe on the wall of an oil collection box and the oil-immersed type transformer provided with the ripple sheets on the wall of the oil tank. The novel oil-immersed type transformer has the advantages of safe and reliable utilization, light related weight and high heat radiation efficiency.
Description
Technical field
The utility model relates to a kind of power transformer, particularly a kind of electric power oil-filled transformer, i.e. a kind of Novel oil-immersed transformer.
Background technology
Oil-filled transformer has good heat dissipation, loss is little, capacity is large, price is low advantage, and the power transformer major part of moving on the electrical network at present is oil-filled transformer.Oil-filled transformer adopts complete oil-filled closed type.The corrugated tank housing is the fuel tank of sealed-for-life with the expansion of self elasticity adaptation oil, and oil-filled transformer has been widely used in each controller switching equipment.For reinforced insulation and cooling condition, the iron core of transformer and winding all immerse together have been filled in the fuel tank of transformer oil.Fuel tank is the shell of oil-filled transformer, and device body (transformer core and winding) just is placed in the fuel tank of having filled transformer oil.Fuel tank generally becomes with Plate Welding, and its structural requirement has certain mechanical strength, except should satisfying the ask for something of transformer when moving, also should satisfy the ask for something of transformer when maintenance and transportation.Transformer oil has two kinds of effects, on the one hand as dielectric; As the medium of heat radiation, namely by the circulation of transformer oil, with the heat that comes out in winding and the iron core, carry out cooling on the other hand.Now transformer heat radiation generally is to utilize on the oil tank wall or the radiating tube that arranges or the corrugated plate that arranges the heat that comes out in cooling winding and the iron core; Radiating tube is set on the oil tank wall dispels the heat, radiating effect is all right, but radiating tube is fragile or lose in transportation and when installing, and makes it to dispel the heat or radiating effect is had a greatly reduced quality; Corrugated plate is set on the oil tank wall dispels the heat, advantage is safe and reliable, because fuel tank all makes with steel plate, and Heavy Weight not only, and also radiating effect is general; Therefore, these two kinds of versions of oil-filled transformer are not ideal.
The utility model content
The utility model is the deficiency for existing oil-filled transformer, and design a kind of Novel oil-immersed transformer, arrange on its oil-collecting tank wall corrugated plate is set on the oil-filled transformer of radiating tube and the oil tank wall oil-filled transformer heat radiation advantage, safe and reliable, weight is relatively light, good heat dissipation effect.
The utility model is achieved in that a kind of Novel oil-immersed transformer, it contains fuel tank, iron core and winding, iron core and winding immerse in the fuel tank of having filled transformer oil together, tank envelope is the square or oval chest of going to the bottom and sealing with the top opening that steel plate is made, be provided with corrugated plate on the tank envelope front and rear wall, tank envelope top is provided with loam cake, loam cake is connected with bolt with tank envelope, on cover and be provided with the turriform binding post, the tank envelope bottom is provided with mounting bracket, characteristics are, are provided with one or two U-shaped radiating tube on the corrugated plate on the tank envelope front and rear wall, and the U-shaped radiating tube communicates with the tank envelope inner chamber;
Useful effect
The utility model is novel in design, arrange on its oil-collecting tank wall corrugated plate is set on the oil-filled transformer of radiating tube and the oil tank wall oil-filled transformer heat radiation advantage, safe and reliable, weight is relatively light, radiating efficiency is high.
Description of drawings
Accompanying drawing 1 is shape and structure schematic diagram of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing,
In the drawings, the 1st, a kind of tank envelope of Novel oil-immersed transformer, it is to make (generally be to become with Plate Welding, weld seam requires manufacturing process to accomplish non-leakage oil) by steel plate, tank envelope 1 is the square or oval chest that a top opening is gone to the bottom and sealed, and is square chest among the figure; Be provided with corrugated plate 2 on the front and rear wall of square chest, corrugated plate 2 is more than two, be provided with one or two U-shaped radiating tube 3 on the corrugated plate 2, U-shaped radiating tube 3 is one among the figure of present embodiment, and U-shaped radiating tube 3 communicates with chest inner chamber (inner chamber of tank envelope 1); The top of tank envelope 1 is provided with loam cake 4, and loam cake 4 can be opened, and loam cake 4 is connected with tank envelope 1 usefulness bolt, is provided with turriform binding post 5 on the loam cake 4, and the tank envelope bottom is provided with mounting bracket 6, is convenient to the mobile of Novel oil-immersed transformer and installs.
Version shown in the drawings also can be used as the structure of an embodiment of the present utility model.
Needing explanation a bit is that oval chest can think that also the four sides outer wall is arranged.
