Abstract
The utility model relates to an oil tank, and particularly relates to an oil tank for an oil-immersed transformer, namely a totally closed corrugated oil tank. The totally closed corrugated oil tank comprises an oil tank housing made of steel plates, wherein the oil tank housing is a square or elliptic box which is provided with an opening top and a closed bottom, and is characterized in that the peripheral walls or the walls on one side or two sides or three sides or four sides of the box are provided with radiating pipes and corrugated plates arranged at intervals; the radiating pipes arranged at intervals are communicated with the cavity of the box; and the radiating pipe and corrugated plate arranged at intervals refer to one radiating pipe and one corrugated pipe at intervals or one radiating pipe and more than two corrugated plates at intervals. The totally closed corrugated oil tank is novel in design, the shortage of the conventional oil tank for an oil-immersed transformer is overcome, and the oil collecting tank wall is provided with a radiating pipe oil tank and the oil tank wall is provided with a corrugated plate oil tank. The totally closed corrugated oil tank is safe and reliable in use, light in weight and high in radiating efficiency.
Description
Technical field
The utility model relates to a kind of fuel tank, particularly a kind of oil-filled transformer fuel tank, i.e. totally-enclosed corrugated tank.
Background technology
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 fuel tank are not ideal.
The utility model content
The utility model is for the deficiency of existing oil-filled transformer with fuel tank, and designs a kind of novel oil-filled transformer fuel tank, i.e. totally-enclosed corrugated tank.It is to arrange on the oil-collecting tank wall corrugated plate fuel tank advantage to be set on radiating tube fuel tank and the oil tank wall, and safe and reliable, weight is relatively light, and heat radiation is imitated.
The utility model is to realize like this, a kind of totally-enclosed corrugated tank, it contains tank envelope, square or the oval chest that the top opening that tank envelope is made with steel plate is gone to the bottom and sealed, characteristics are provided with radiating tube and corrugated plate separately around being on the wall at wall or one side or two sides or three or four sides, and radiating tube separately communicates with the chest inner chamber;
The utility model also can be achieved like this, radiating tube separately and corrugated plate be one separately radiating tube and a slice corrugated plate separately or be a radiating tube separately with comprise two two above corrugated plates separately;
The utility model also can be achieved like this, and all there is corrugated plate on each radiating tube both sides separately.
Useful effect
The utility model is novel in design, arranges on its oil-collecting tank wall and corrugated plate fuel tank advantage is set on radiating tube fuel tank and the oil tank wall, and safe and reliable, weight is relatively light, and radiating efficiency is high.
Description of drawings
Accompanying drawing is structural representation 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, tank envelope is made (generally be to become with Plate Welding, weld seam requires manufacturing process to accomplish non-leakage oil) by steel plate, and tank envelope 1 is the square or oval chest of 5 sealings of going to the bottom of a top opening, is square chest among the figure; Can be provided with separately radiating tube 3 and corrugated plate 2 around the square chest on the wall at wall or one side or two sides or three or four sides, radiating tube 3 communicates with the chest inner chamber, that chest front and back two sides is provided with radiating tube 3 and corrugated plate 2 separately among the figure, radiating tube 3 separately and corrugated plate 2 be a radiating tube and a slice corrugated plate 2 separately; 4 are arranged on the suspension hook under the top panel, in order that convenient lifting transformer, quantity is four; Be (attached not shown in FIG.) that case lid is arranged on tank envelope 1 top, case lid can be opened, rely on case along around many bolts and tank envelope 1 tighten together; 5 the following mounting bracket (attached not shown in FIG.) that is provided with of going to the bottom of tank envelope 1 is convenient to the installation of transformer.
Oiltank structure shown in the accompanying drawing also can be used as the structure of an embodiment of the present utility model.During use, device body (transformer core and winding) is placed in the tank envelope 1, adds some transformer oil, at tank envelope 1 upper cover upper box lid, connects wire, fastening getting final product.
Needing explanation a bit is that oval chest can think that also the four sides outer wall is arranged.
