Abstract
The utility model relates to the oil storage cabinet of a transformer, composed of a box body, the plug of the box body, the end cover of the box body, an oil feeding hole, a moisture absorbing device, a connecting pipe, an oil discharge pipe, a support, an oil level gauge, etc. The box body is a horizontal cuboid, and the box body is provided with a floating plate which can rise and fall according to the oil level. Compared with the existing oil storage cabinets without capsules, the contact area of oil and atmosphere is reduced. The influence to the transformer oil caused by moisture and oxygen in the atmosphere can be decreased, and therefore, the service life of a transformer is extended. In addition, the rest structure of the oil storage cabinet is as the same as the traditional oil storage cabinets without capsules, and therefore, the traditional transformers can also be matched with the utility model.
Description
The utility model belongs to a kind of protection equipment for transformer, relates to a kind of transformer oil conservator.
Transformer is divided into dry type or oil immersed type two big classes, and present employed power transformer great majority adopt oil immersed type.And oil-filled transformer in use, influenced by moisture, oxygen etc., and transformer oil can wear out gradually, go bad, thereby influence the useful life of transformer.For reducing the influence of these factors, most of transformers all have a kind of protective device, and in order to reduce the contact area of transformer oil and air, oil makes moist and the degree of oxidation thereby reduce, and this device is transformer oil conservator (also being conservator traditionally).
Existing oil-filled transformer oil conservator all adopts horizontal cylindrical box, and it is by oil pipe and transformer link down.In transformer when operation,, fry dried food ingredients is given birth to and is expanded, and the oil that of expanding enters oil conservator along oil pipe down; When transformer was out of service, oil cooling contracted, and a part of oil is got back in the transformer along following oil pipe again.This oil conservator is divided into again capsule-type and no capsule-type.Horizontal cylindrically have the transformer oil conservator of capsule-type fully to isolate transformer oil and air, but cost height, manufacturing mounting process complexity, only in the large-scale power transformer more than 8000 kilovolt-amperes, use, and horizontal cylindrical no capsule-type oil conservator is compared with the transformer of no oil conservator, can slow down that transformer oil makes moist, oxidated speed, and cost is low, install easily, but anti-oil degradation can not show a candle to the oil conservator of capsule-type.
The purpose of this utility model is a kind of novel transformer oil conservator of design, make transformer oil under identical temperature, humidity and atmospheric pressure, compare with no capsule-type oil conservator, can reduce that transformer oil makes moist, oxidated degree, thereby improve the useful life of transformer.
The purpose of this utility model realizes by following scheme: the transformer oil conservator is made up of casing, casing plug, housing plate, oil filler point, dehydrating breather tube connector, following oil pipe, support, oil level gauge etc.Described casing is horizontal cuboid, and horizontal sectional area equates everywhere in the casing, and casing is built-in with the kickboard of an energy with the pasta lifting.
The utility model is traditional horizontal cylinder not to be had the capsule-type oil conservator change into horizontal cuboid, installed kickboard additional on the pasta in the utility model simultaneously, slit between only remaining kickboard of the contact area of transformer oil and atmosphere and oil conservator casing wall is located like this, compare with existing no capsule-type oil conservator, significantly reduced the contact area of oil with atmosphere, reduced the influence of moisture in the atmosphere and oxygen, thereby prolonged useful life of transformer transformer oil.In addition, all the other structures of this oil conservator are identical with traditional oil conservator, so still can supportingly use with common transformation.
Fig. 1 looks cross section view for master of the present utility model;
Fig. 2 is a side-looking cross section view of the present utility model;
Fig. 3 is the structural representation of kickboard in the utility model;
Be described as follows below in conjunction with drawings and the specific embodiments:
By Fig. 1 and Fig. 2 as can be known, the transformer oil conservator is by casing 1, casing plug 2, housing plate 3, oil filler point 4, dehydrating breather tube connector 5, oil pipe 6, support 7, oil level gauge 8 etc. are formed down.Described casing 1 is horizontal cuboid, and the horizontal sectional area in the casing equates everywhere.Bottom half is connected with oil pipe 6, and following oil pipe is connected with oil tank of transformer.When transformer moved, the transformer oil 13 that expands existed in the oil conservator.Be built-in with a kickboard 9 at casing 1, the length of kickboard and the wide length that is slightly less than casing and wide.Therefore this kickboard can be floated with the lifting of pasta.Because kickboard floats on the pasta forever, significantly reduced the contact area (contacting the gap of only remaining kickboard and casing wall between transformer oil and atmosphere) of oil and atmosphere, so effectively alleviated the influence of moisture in the atmosphere and oxygen to transformer oil.
For improving the buoyancy of kickboard 9, kickboard can be made structure as shown in Figure 3, that is: kickboard adopt anticorrosion, grease proofing, buoyancy big, the effective sandwich construction of air-isolation.
In the utility model, an end face 10 of kickboard is made by the no rotten light wood of dehydration, and another end face 11 is made by galvanized iron sheet, also is filled with foamed polystyrene 12 between both ends of the surface.So both guaranteed that kickboard had enough buoyancy, can lifting with the lifting of transformer pasta, also can effectively keep apart contacting of oil and atmosphere simultaneously, thus the useful life of prolongation transformer.
