Description
Technical field
The utility model relates to transformer technology field, be specifically related to a kind of oil-filled transformer.
Background technology
Distribution transformer is one of visual plant in industrial and mining enterprises and civil buildings power supply-distribution system, and it is down to by 10kV or 35kV network voltage the 230/400V busbar voltage that user uses.This series products is applicable to exchange 50Hz, the maximum rated capacity 2500kVA of three-phase (single-phase maximum rated capacity 833kVA, general recommendation single-phase transformer not), indoors (outward) used, and capacity can be arranged on bar at 315kVA and when following, ambient temperature is not higher than 40 ℃, be not less than-25 ℃, 30 ℃ of the highest mean daily temperatures, 20 ℃ of the highest year-round average temperatures, relative humidity is no more than 90% (25 ℃ of ambient temperatures), and height above sea level is no more than 1000m.
In order to meet the air insulation distance of high-power transformer oil conservator to sleeve pipe, oil conservator can be positioned over to outside, fuel tank termination, fuel tank tank wall will be departed from the center of oil conservator for this reason, reach sometimes 1m, even farther, therefore the stable support for oil conservator is the problem that needs consideration.And the oil conservator backing material of traditional oil-filled transformer adopts angle steel, oil conservator supporting leg is perpendicular to the support of fuel tank, and relatively independent separately, supporting leg, support and oil conservator form a rectangle, and oil conservator supporting leg and tank support adopt single bolted.This kind of structure, when oil conservator front is stressed, its intensity is reliably, if but the strong effect in side can produce double swerve obviously.In actual installation process, operator reflects that oil conservator is unstable sometimes, if firmly push-and-pull will feel that oil conservator slightly rocks, rocks out of doors the most violent, very dangerous when wind direction vertically acts on oil conservator end face.
Utility model content
For the deficiency existing in prior art, the utility model provides a kind of oil-filled transformer, effectively improves the stability of oil conservator, and has reduced materials'use amount, and simple installation has improved the result of use of oil-filled transformer, safe and reliable.
To achieve these goals, the utility model is to realize by the following technical solutions: oil-filled transformer, comprise oil tank of transformer top cover, supporting leg lower flange, supporting leg, supporting leg upper flange and oil conservator, on oil tank of transformer top cover, by supporting leg lower flange, be connected with supporting leg, supporting leg upper end is connected with oil conservator by supporting leg upper flange, described supporting leg lower flange and supporting leg upper flange are all bolted, described oil conservator and seamless steel pipe junction are also provided with rubber blanket, can make well between seamless steel pipe and oil conservator closely fixing, described oil tank of transformer top cover and supporting leg lower flange junction are also provided with strengthens pad, the support force that can disperse well supporting leg, stability is better.The angle of inclination of described supporting leg and oil tank of transformer top cover is 60 °.
As preferably, described supporting leg is two seamless steel pipes.
As preferably, described supporting leg lower flange is square, and Qie Qi center is provided with elliptical aperture, and surrounding is evenly distributed with bolt hole.
As preferably, described supporting leg upper flange is circular, and its center is provided with circular hole, and surrounding is evenly equipped with bolt hole.
The beneficial effects of the utility model:
1, good stability, supporting construction of the present utility model is all having larger nargin aspect bonding strength and the strength of materials, be reliably, can guarantee safety and stability when actual motion.
2, simple in structure, operating efficiency is high.Compared with traditional oil conservator supporting construction, structure of the present utility model only needs two seamless steel pipes and a small amount of flange, bolt, the specification of parts is few, therefore its structure is simpler, need to weld and fastening quantity also greatly reduces simultaneously, and then improved processing and installation effectiveness, saved cost of labor.Also saved material cost, had good economic benefit simultaneously.
3, good looking appearance.Because structural member is few, and the shape that takes full advantage of material determines the feature of intensity, makes it more attractive in appearance in shape.This structure also can be adjusted according to actual conditions the support angle of steel pipe simultaneously
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, describe the utility model in detail;
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of supporting leg lower flange of the present utility model;
Fig. 3 is the structural representation of supporting leg upper flange of the present utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
With reference to Fig. 1-3, this embodiment is by the following technical solutions: oil-filled transformer, comprise oil tank of transformer top cover 1, supporting leg lower flange 2, supporting leg 3, supporting leg upper flange 4 and oil conservator 5, on oil tank of transformer top cover 1, by supporting leg lower flange 2, be connected with supporting leg 3, supporting leg 3 upper ends are connected with oil conservator 5 by supporting leg upper flange 4, described supporting leg lower flange 2 and supporting leg upper flange 4 are all fixing by bolt 6, described supporting leg 3 is two seamless steel pipes, described oil conservator 5 is also provided with rubber blanket with seamless steel pipe junction, can make well between seamless steel pipe and oil conservator 5 closely fixing, described oil tank of transformer top cover 1 is also provided with and strengthens pad with supporting leg lower flange 2 junctions, the support force that can disperse well supporting leg, stability is better.
It should be noted that described supporting leg 3 and the angle of inclination of oil tank of transformer top cover 1 are 60 °; Described supporting leg lower flange 2 is square, and Qie Qi center is provided with elliptical aperture, and surrounding is evenly distributed with bolt hole.
In addition, described supporting leg upper flange 4 is circular, and its center is provided with circular hole, and surrounding is evenly equipped with bolt hole.
This embodiment it mainly adopt two seamless steel pipes to support, and certain angle that tilts as required, meets the minimum air void of sleeve pipe electrified body to oil conservator.Steel pipe two ends welded flange, fixes with oil conservator and fuel tank respectively with bolt.From deflection of beam stress analysis, steel pipe has a neutral line when flexural deformation, Yi Qiwei circle, and half of steel pipe is stressed, and second half is subject to pulling force, therefore has very strong bending resistance.Flange bolt is circumference or surrounding distribution simultaneously, is not single unstable distribution, therefore stressed in any direction, has a plurality of bolts to bear, thereby has strengthened whole stability.
