Abstract
The utility model provides a bellows for a transformer. The bellows comprises a bellows main body (1), wherein an upper end flange (2) and a lower end flange (3) are installed at the two ends of the bellows main body (1). The bellows is characterized in that upper fixed lugs (4) are uniformly distributed on the outer circumferential surface of the upper end flange (2); lower fixed lugs (5) are installed on the outer circumferential surface of the lower end flange (3), corresponding to the upper fixed lugs (4); through holes are arranged in the centers of the upper fixed lugs (4) and the lower fixed lugs (5); screws (6) with threads at the two ends pass through the through holes; and nuts (7) are installed on the threads of the screws on the outer sides of the upper fixed lugs (4) and the lower fixed lugs (5). The bellows has the following beneficial effects that: extension or compression of the bellows can be adjusted by the threads according to the actual requirements, thus solving the problem of deviation between the actual floor height of the substation and the standard value.
Description
Technical field
The utility model belongs to electrical equipment mounting technique field, specifically just relates to a kind of transformer and uses bellows.
Background technique
In short supply along with the development of urban distribution network and land resources; Particularly for large size city; The soil cost is a part very important in the transformer substation construction expense; In order to reduce electric substation's floor space, economize the land resource, mounting structure split type about the large-capacity power design of transformer is become is just gradually by extensive employing.Split type up and down transformer is meant that transformer body is installed in the transformer chamber of electric substation's Stall; And its radiator part is installed concentratedly in the second floor radiator chamber that is positioned at directly over it; Be communicated with main body and radiator through transformer turnover oil pipe, reach the effect of transformer oil cycle heat radiation.In order to solve the problem that there are deviation in actual floor height of electric substation and reference value; Generally often between transformer turnover oil pipe and main body, install bellows additional; The performance that can stretch in right amount or compress through bellows; Remedy because there are the problem of deviation in the actual floor height of electric substation and reference value, still in practical work process, usually can run into bellows and be difficult to the problem that stretches on demand or compress smoothly.
The model utility content
The utility model technical barrier to be solved provides a kind of transformer and uses bellows, and it can realize that bellows stretches according to actual needs when mounted or compresses purpose.
Technological scheme
In order to solve above-mentioned technical barrier; The utility model designs a kind of transformer and uses bellows; It comprises the bellows main body, and upper end portion flange and underpart flange are equipped with in bellows main body two ends, it is characterized in that: the flange outer peripheral surface evenly distributes fixedly ear is housed in the upper end portion; On the flange outer peripheral surface of underpart fixedly the ear corresponding position fixedly ear is housed down; Upward fixedly ear has through hole with following fixedly ear central position, passes the screwed screw rod in two ends in the through hole, and upward fixedly ear is equipped with nut with following fixedly ear both ends of the surface screw flight place.
Said last fixedly ear is a rectangle with following fixedly ear, and length is 50～60mm, and width is 50～60mm.
Said through-hole aperture is φ 22～φ 24.
Carrying out transformer when installing, according to the difference of civil engineering layer height, when bellows need stretch, can with the nut of upper and lower end parts flange both ends of the surface laterally direction carry out knob, the displacement through the nut knob reaches the effect that bellows is stretched; Otherwise, when bellows need compress, can with the nut of upper and lower end parts flange both ends of the surface to the inside direction carry out knob, the displacement through the nut knob reaches the bellows compression effects equally.
Beneficial effect
The utility model can utilize the stretching or the compression of threaded adjusting bellows according to actual needs, thereby there are the problem of deviation in solution actual floor height of electric substation and reference value.

Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is further specified.
Shown in accompanying drawing 1, existing transformer corrugated tube end flange is unfixing, can't regulate that bellows length solves because there are the problem of deviation in actual floor height of electric substation and reference value; And shown in accompanying drawing 2 and accompanying drawing 3; A kind of transformer that the utility model designed is used bellows, and it comprises bellows main body 1, and upper end portion flange 2 and underpart flange 3 are equipped with in bellows main body 1 two ends; Wherein, Fixing ear 4 on flange 2 outer peripheral surfaces in upper end portion evenly distribute the rectangle that 4 55*55 are housed, on underpart flange 3 outer peripheral surfaces fixedly ear 4 corresponding positions fixedly ear 5 is housed under the rectangle of 55*55, upward fixedly ear 4 and time fixedly ear 5 central positions have φ 23 through holes; Pass the screwed screw rod 6 in two ends in the through hole, upward fixedly ear 4 is equipped with nut 7 with following fixedly screw flight place, ear 5 bi-side.
Shown in accompanying drawing 4; In the real transformer erecting bed, according to the difference of civil engineering layer height, when bellows need stretch; Can with the nut 7 of upper and lower end parts flange both ends of the surface laterally direction carry out knob, the displacement through nut 7 knobs reaches the effect that bellows is stretched; Otherwise, when bellows need compress, can with the nut 7 of upper and lower end parts flange both ends of the surface to the inside direction carry out knob, the displacement through the nut knob reaches the bellows compression effects equally.After bellows installs; Can as required screw rod 6 and nut 7 be unloaded the installation that is used for next product; The utility model can utilize the stretching or the compression of threaded adjusting bellows according to actual needs, thereby there are the problem of deviation in solution actual floor height of electric substation and reference value.
Claims (3)
1. a transformer is used bellows; It comprises bellows main body (1); Upper end portion flange (2) and underpart flange (3) are equipped with in bellows main body (1) two ends; It is characterized in that: the flange in the upper end portion (2) outer peripheral surface evenly distributes fixedly ear (4) is housed, on underpart flange (3) outer peripheral surface fixedly ear (4) corresponding position fixedly ear (5) is housed down, upward fixedly ear (4) and time fixedly ear (5) central position have through hole; Pass the screwed screw rods in two ends (6) in the through hole, upward fixedly ear (4) and following fixedly ear (5) both ends of the surface screw flight place are equipped with nut (7).
