Abstract
The utility model relates to a structure of a transformer oil tank cover. The structure comprises a cover board. Box edge holes are arranged at four sides of the cover board. The structure is characterized in that stop strips are arranged below the edge at four sides of the cover board; the stop strips below the edge at four sides of the cover board are used for resisting illumination of solar ultraviolet on a sealing strip; the sealing strip can be prevented from aging because of the solar ultraviolet; the service life of the sealing strip is increased; the hidden trouble of oil leakage of a sealed transformer is reduced; the maintenance cost is reduced; and the reliability of the transformer is increased.
Description
Technical field
The utility model relates to the parts of transformer, especially a kind of oil tank of transformer case lid.
Background technology
Oil-immersed power transformer seepage oil is the long-standing quality problems of transformer industry.Technology tackling key problem through nearly ten years has obtained effect preferably.But compare with the like product of external industrially developed country; Seepage oil also fundamentally is not resolved; Particularly middle-size and small-size manufacturer, the problem that exists in this respect is more general, and transformer seepage oil mostly occurs in the commissure, sealing surface and encapsulant etc. are located.Be sealed in the transformer seepage oil and be more common a kind of phenomenon, transformer cover plate and case along between be provided with sealing strip and positive stop strip, case along bolt fastening down; Sealing strip is crushed, owing to do not take measures between transformer cover plate and case edge, under the irradiation of ultraviolet ray to sealing strip of the sun; Sealing strip is easy to wear out; Transformer seal leak oil phenomenon occurs, increased maintenance cost, reduced the reliability of transformer.
The utility model content
The utility model main purpose is to provide a kind of structure of corrugated tank of transformer, and it is simple in structure, can be fit to the production of jumbo corrugated tank transformer.
The technical scheme that technical problem adopted that the utility model solves is: a kind of structure of oil tank of transformer case lid, comprise cover plate, and be provided with case along the hole all around on the cover plate, it is characterized in that being provided with blend stop below the cover plate edge all around.Owing to be provided with blend stop below the edge around cover plate, when being installed to fuel tank, be provided with sealing strip and positive stop strip between cover plate and case edge; Blend stop under the edge around the cover plate has blocked the irradiation of the ultraviolet ray of the sun to sealing strip; Block ultraviolet ray and infrared ray, alleviated the irradiation in Taiyuan to a great extent, prevented that the ultraviolet of sunray of sealing strip from wearing out; The life-span of sealing strip is improved; Reduce the hidden danger of transformer seal leak oil, reduced maintenance cost, improved the reliability of transformer.
As preferably, blend stop is the flanging of cover plate.The cover plate extension adopts the method for flanging, has improved the aesthetics of transformer like this.
The beneficial effect of the utility model is: the blend stop under the edge around the cover plate has blocked the irradiation of the ultraviolet ray of the sun to sealing strip; The ultraviolet of sunray that has prevented sealing strip wears out; The life-span of sealing strip is improved; Reduce the hidden danger of transformer sealed transformer seepage oil, reduced maintenance cost, improved the reliability of transformer.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is that the utility model is implemented main TV structure sketch map;
Fig. 2 is the A-A profile of the utility model embodiment Fig. 1.
Among the figure: 1, cover plate 2, case along the hole 3, blend stop.
Embodiment
Extremely shown in Figure 2 according to Fig. 1 below, embodiment states to the utility model
In Fig. 1, a kind of structure of oil tank of transformer case lid comprises cover plate 1, is provided with case around on the cover plate 1 along the hole 2 and installing holes such as high-low pressure sleeve pipe and pressure relief valve, and cover plate 1 is provided with blend stop 3 below the edge all around.Blend stop is the method that cover plate 1 extension adopts flanging, sells off formation, has improved the aesthetics of transformer like this.
Owing to be provided with blend stop 3 below the edge around cover plate 1, when being installed to fuel tank, be provided with sealing strip and positive stop strip between cover plate 1 and case edge; Blend stop 2 under the edge around the cover plate 1 has blocked the irradiation of the ultraviolet ray of the sun to sealing strip; Block ultraviolet ray and infrared ray, alleviated the irradiation in Taiyuan to a great extent, prevented that the ultraviolet of sunray of sealing strip from wearing out; The life-span of sealing strip is improved; Reduce the hidden danger of transformer seal leak oil, reduced maintenance cost, improved the reliability of transformer.
Claims (2)
1. the structure of an oil tank of transformer case lid comprises cover plate, is provided with case along the hole all around on the cover plate, it is characterized in that being provided with blend stop below the cover plate edge all around.
