Abstract
The utility model relates to a kind of single column oil-immersed-type mutual inductor oil box and is made up of top tank, lower fuel tank, an insulated column fixed disk, the as a whole compressing housing matched with instrument transformer winding profile of top tank; The lower fuel tank shell of lower fuel tank is a lower fuel tank housing matched with instrument transformer winding profile, owing to top tank shell, lower fuel tank shell corner to be designed to the structure of arc-shaped, thus avoid the generation of fuel tank corner electric field non-uniform phenomenon, facilitate the shaping of extending of sheet material simultaneously; Because top tank shell is designed to the shape that matches with instrument transformer winding profile, thus make electric fields uniform, decrease the volume and weight of fuel tank simultaneously; Because lower fuel tank shell is designed to the shape that matches with instrument transformer winding profile, thus decrease oil reserve on the basis of ensuring the quality of products, reduce the cost of product; Due to rational in infrastructure compact, dependable performance, so there is very large practical and popularizing value.
Description
Technical field
The utility model relates to oil immersion type mutual-inductor, specifically a kind of single column oil-immersed-type mutual inductor oil box.
Background technology
Through retrieval Patent documents of interest, not yet retrieve a kind of single column oil-immersed-type mutual inductor oil box identical with the utility model structure at present.The version that existing oil-immersed-type mutual inductor oil box generally takes general steel plate to be welded is to make instrument transformer fuel tank, volume is large, the insulating oil used is many, increases product cost, simultaneously because weld seam is many, weld seam after welding is needed to carry out grinding process, waste time and energy, and the remitted its fury after polishing, in transport and use procedure, easily there is cracking oil leakage phenomenon in finished product, so be necessary to be improved existing oil-immersed-type mutual inductor oil box, to improve the performance of product.
Summary of the invention
The purpose of this utility model a kind of method shaping at employing integrally stretching will be provided to make mutually mate with instrument transformer winding, has compact conformation, a kind of single column oil-immersed-type mutual inductor oil box that performance is good.
Technical characteristic of the present utility model is: on the basis considering compact conformation, dependable performance, be designed to a kind of single column oil-immersed-type mutual inductor oil box be made up of top tank, lower fuel tank, an insulated column fixed disk, the as a whole compressing housing matched with instrument transformer winding profile of described top tank; The lower fuel tank shell of described lower fuel tank is a lower fuel tank housing matched with instrument transformer winding profile.
Described top tank is made up of outlet cassette holder, top tank shell, top tank cover plate, the as a whole compressing arc structure body that matches with instrument transformer winding of top tank shell.
Described lower fuel tank is made up of support, lower fuel tank shell, lower fuel tank cover plate, obturating plug, the as a whole compressing arc structure body that matches with instrument transformer winding of described lower fuel tank shell.
During installation, the winding of instrument transformer to be installed in arcuation space that lower fuel tank and top tank formed and to be fixed, sealing is fixed by sealing gasket between top tank cover plate and lower fuel tank cover plate by bolt, form a sealed cavity, insulating oil is injected by plug cock seat, whole winding is made to be immersed in the oil pocket of formation, the housing of top tank and lower fuel tank shell are extended by plate stamping the arcuation body being formed and mutually mate with winding profile, top tank shell, lower fuel tank shell is made and be its objective is in order on guaranteed performance basis with the arc body of winding mating shapes, reduce instrument transformer weight, make electric fields uniform design simultaneously, top tank shell, lower fuel tank shell corner is designed to its object of arc-shaped to make internal electric field even, improve performance, reduce point potential electrical field uneven and design.
The utility model has the advantages that: owing to top tank shell, lower fuel tank shell corner to be designed to the structure of arc-shaped, thus avoid the generation of fuel tank corner electric field non-uniform phenomenon, facilitate the shaping of extending of sheet material simultaneously; Because top tank shell is designed to the shape that matches with instrument transformer winding profile, thus make electric fields uniform, decrease the volume and weight of fuel tank simultaneously; Because lower fuel tank shell is designed to the shape that matches with instrument transformer winding profile, thus decrease oil reserve on the basis of ensuring the quality of products, reduce the cost of product; Due to rational in infrastructure compact, dependable performance, so there is very large practical and popularizing value.
