Abstract
The utility model discloses an oil -immersed transformer of reduction in production cost and the improvement transformer stability in the transportation is used through economizing on fuel. A lateral wall, lower indisputable yoke of oil -immersed transformer, including the box the lateral wall lower part is to the indent, and indisputable yoke matches with establishing in it down for size that inside concave part divides. Because the utility model discloses by traditional box by last under to internal diameter size uniformity, establish into the lateral wall lower part to the shape of indent, make the box by last under to internal diameter size nonconformity to the capacity of the oil in the box can be reduced and manufacturing cost has been reduced. Because reduced lower indisputable yoke and lateral wall distance within a definite time that the lower part lateral wall was placed, it is too big to avoid the transformer to remove the range, damages lead wire or insulating, assurance oil -immersed transformer's electrical safety distance and the stability in the transportation.
Description
Technical field
The utility model relates to transformer, particularly a kind of oil-filled transformer.
Background technology
Increasingly competitive along with transformer industry, reducing costs is the matter of utmost importance that each transformer production producer faces, and is also the top priority of each design of transformer personnel.At present, in oil-filled transformer casing, internal diameter size is consistent from top to bottom, and the iron core column intermediate sleeve be located in casing is equipped with winding, and the width being set with the iron core column place of winding is greater than the upper yoke, the lower yoke width that are not set with winding up and down.Under normal circumstances, people make an effort on the sheet metal thickness of oil-filled transformer casing, realize fuel-economizing, reduce the object of production cost.In addition, due to be not wound around winding upper and lower iron yoke outside and distant relative between winding outer lateral extent transformer-cabinet sidewall of distance between transformer tank body sidewall, to the certain influence that the stability of transformer in transport use procedure is also brought.
Summary of the invention
The technical problem that the utility model solves is to provide a kind of oil-filled transformer being reduced production cost by fuel-economizing and improve the stability of transformer in transport uses.
The technical solution of the utility model is, a kind of oil-filled transformer, includes the sidewall of casing, lower yoke, and described lower sidewall concaves, concave part size with establish lower yoke within it to match.
Because the utility model is by traditional casing internal diameter size consistency from top to bottom, be set as the shape that lower sidewall concaves, internal diameter size is inconsistent from top to bottom to make casing, thus can reduce the capacity of the oil in casing and reduce production cost.Owing to reducing the distance between the lower yoke of lower sides placement and sidewall, avoid transformer mobile range excessive, damage lead-in wire or insulation, ensure the stability in the electrical safety Distance geometry transportation of oil-filled transformer.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail, the iron core column 4 it being set with winding 3 is provided with in the casing of transformer, iron core column is connected with upper yoke 2, lower yoke 5 up and down respectively, iron core column 4 is set with winding 3, sidewall 1 bottom of casing concaves, namely place the side-walls of lower yoke 5 to concave, the size of female parts with establish lower yoke 5 within it to match, lower yoke 5 is just in time located in the casing of female parts.
For a casing for 970*490*810, in traditional transformer-cabinet, contain oil 346 kilograms, in the utility model transformer-cabinet, contain oil 331.2 kilograms, every platform can save 14.8 kilograms of oil, as produced 5000 per year, then can save 74000 kilograms, economic benefits.
The above is only preferred embodiment of the present utility model, protection range of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, not departing from the some improvements and modifications under the utility model principle prerequisite, also should be considered as protection range of the present utility model.
