Abstract
The utility model provides a corrugated oil tank of a transformer, which comprises a cubic oil tank body, long-edge corrugated pieces arranged on the outer side of the long edge of the oil tank body, and wide-edge corrugated pieces arranged on the outer side of the wide edge of the oil tank body; the wide-edge corrugated pieces are uniformly arranged on the whole wide edge; and the long-edge corrugated pieces are uniformly arranged on the whole long edge. For the corrugated oil tank, the traditional design that the corrugated pieces are partially arranged on the long edge and the wide edge of the oil tank body is changed, the long edge and the wide edge of the oil tank body are fully distributed with the corrugated pieces, additional long-edge corrugated pieces are arranged on the outer side of the extension line of two ends of the long edge of the oil tank body, and positions of four corners are fully utilized, thus enlarging the effective heat dissipation area of the corrugated oil tank, improving the heat dissipation coefficient, and solving the problem that the effective heat dissipation area of the corrugated oil tank is insufficient. Simultaneously, the corrugated pieces at four sides of the oil tank are designed to be connected into an integral reinforcing rib, thus greatly enhancing the strength of the corrugated pieces.
Description
Technical field
The utility model relates to electrical equipment technical field, more particularly, relates to a kind of corrugated tank of transformer.
Background technology
The main feature of full-sealed transformer is to adopt an effective measure, and makes transformer oil and air isolated fully, avoids the transformer oil oxidation and makes moist, and to slow down transformer insulated aging speed, prolongs the useful life of transformer.And heat dissipation problem also is to influence a transformer key factor in useful life.
At present, full-sealed transformer adopts corrugated tank.The heat radiation of corrugated tank mainly is to rely on corrugated plate to loose the caloric value of transformer to heat in air through the ripple tank wall.The corrugated tank structure chart of prior art is as shown in Figure 1, the oil box side of being body, and the long limit of oil box and broadside are part corrugated plate are set, and its cooling surface area is made up of two parts surface area: the one, the surface area of corrugated plate and fuel tank body wall; The 2nd, the position sheet area at four angles of oil box.But the position sheet area at these four angles is smaller, so the area of dissipation of corrugated tank is very limited.On the other hand, bigger its internal loss of the capacity of transformer is big more, requires oil tank of transformer efficiently radiates heat area big more, tends to occur the heat radiation requirement that fuel tank efficiently radiates heat area can not satisfy the transformer loss heating.Therefore, be badly in need of a kind ofly increasing the efficiently radiates heat area at present, thereby improve the corrugated tank of transformer heat-sinking capability.
The utility model content
The purpose of the utility model is to overcome shortcoming of the prior art with not enough, and a kind of corrugated tank that increases the transformer of area of dissipation is provided, thereby improves the heat-sinking capability of transformer.
In order to achieve the above object; The utility model is achieved through following technical proposals: a kind of corrugated tank of transformer, comprise the side's of being body oil box, be arranged on the long limit corrugated plate in the outside, the long limit of oil box and be arranged on the broadside corrugated plate outside the oil box broadside; It is characterized in that: said broadside corrugated plate evenly is arranged on the whole broadside; Said long limit corrugated plate evenly is arranged on the whole long limit.
As above technical scheme all is covered with the corrugated plate that is used to dispel the heat on the long limit of whole oil box and broadside, increased the area of heat radiation.
As preferably, on the outside of two ends, the long limit of said oil box extended line, also be provided with additional long limit corrugated plate; Broadside corrugated plate on the oil box, long limit corrugated plate and additional long limit corrugated plate are uniformly distributed with and are looped around the said oil box outside, form square framework.Such technical scheme has made full use of the space that the broadside corrugated plate extends out at two ends, long limit, through additional long limit corrugated plate is set, further increases the area of heat radiation.
Broadside corrugated plate on the said oil box, long limit corrugated plate and additional long limit corrugated plate are integral through reinforcement is fixedly connected.Such design can strengthen the intensity of corrugated plate greatly.
Said broadside corrugated plate, long limit corrugated plate and additional long limit corrugated plate are fixed by welding on the oil box.
Described broadside corrugated plate, long limit corrugated plate and additional long limit corrugated plate are rugosity.The design of rugosity can improve the heat dispersion of corrugated plate.
Described reinforcement is fixed by welding on broadside corrugated plate, long limit corrugated plate and the additional long limit corrugated plate.
Described reinforcement has two, is separately fixed at the upper and lower edge of broadside corrugated plate, long limit corrugated plate and additional long limit corrugated plate.
Compared with prior art, the utlity model has following advantage and beneficial effect:
1, the utility model has changed traditional design that only at the long limit and the broadside of oil box the part corrugated plate is set; Long limit and broadside through at oil box are covered with corrugated plate; And additional long limit corrugated plate is set on the outside of two ends, the long limit of oil box extended line, make full use of the position at four angles of oil box, thereby increase the efficiently radiates heat area of corrugated tank; Improve coefficient of heat transfer, solved the not enough problem of high-power transformer fuel tank efficiently radiates heat area.
2, the corrugated tank of the utility model through the reinforcement that design can make the four sides corrugated plate of fuel tank fuse, has strengthened the intensity of corrugated plate greatly.
