Abstract
The utility model discloses an energy-saving ripple radiator for an oil immersed transformer, comprising corrugated plates, an oil inlet, an oil outlet, an upper end welding edge of the corrugated plate, a lower end welding edge of the corrugated plate, and a connecting edge, wherein the middle part of the corrugated plate is provided with a rectangular or elliptical groove, and strengthening ribs are welded between the corrugated plates. The energy-saving ripple radiator for the oil immersed transformer has good intensity, good radiating effect, lower electricity consumption, and better energy-saving effect, is not easy to cause the phenomenon that two metal plates of the corrugated plate expand and deform seriously when the oil temperature and the oil pressure of the transformer are higher, and has safer use and better effect.
Description
Technical field
The utility model relates to transformer, particularly relates to the heat abstractor of oil-immersed type transformer fuel tank, more specifically relates to the energy-saving ripple radiator of a kind of oil-immersed type transformer.
Background technology
The ripple radiator of oil-immersed type transformer is very important parts in the oil-immersed type transformer fuel tank, and it is directly connected to height, planform, production cost, useful life of radiating effect, the electrical loss of oil-immersed type transformer etc.The ripple radiator also is commonly called as and is corrugated plate.The ripple radiator of existing oil-immersed type transformer is with being welded after the rectangular metal plate punch forming, in a ripple radiator, the multi-disc corrugated plating is arranged, in with a slice corrugated plating, the middle part of two metallic plates is dull and stereotyped, and the upper end of two metallic plates, lower end correspondence weld together.The ripple radiator is welded on the relevant position of oil-immersed type transformer fuel tank.The ripple radiator of existing oil-immersed type transformer, though be better than the tubular radiator of oil-immersed type transformer, but the lower defective of ripple intensity of radiator that has oil-immersed type transformer, when higher and oil pressure is big in the oil temperature of transformer, be prone to two serious dilatancies of metallic plate of corrugated plating, be two serious evaginations of metallic plate of emersion wave card, ripple radiator and transformer can not be used; If the distortion of two metallic plate slight expansion of emersion wave card, i.e. two of the emersion wave card slight evaginations of metallic plate then reduce the radiating effect of oil-immersed type transformer greatly, and the electrical loss of oil-immersed type transformer is raise greatly.Simultaneously, because the ripple intensity of radiator of existing oil-immersed type transformer is lower, make the corrugated-fin radiator of oil-immersed type transformer mainly be applicable to small-sized oil-immersed type transformer.Therefore, in order to prevent two metallic plate dilatancies of corrugated plating, improve the radiating effect of ripple radiator, reduce the electrical loss of oil-immersed type transformer, improve the ripple intensity of radiator, improve the scope of application of ripple radiator, existing ripple heat spreader structures haves much room for improvement.
Summary of the invention
The purpose of this utility model:, and provide a kind of oil-immersed type transformer energy-saving ripple radiator for the some shortcomings of the ripple radiator that overcomes existing oil-immersed type transformer.
The technical solution of the utility model: the energy-saving ripple radiator of a kind of oil-immersed type transformer, comprise corrugated plating, oil inlet and outlet, corrugated plating upper end welding edge, corrugated plating lower end welding edge, fillet, be provided with groove at the middle part of corrugated plating.
Two groove symmetries in the above-mentioned same corrugated plating, the distance of two grooves in same corrugated plating is the 3-8 millimeter.
Be welded with reinforcement between the above-mentioned corrugated plating.
Above-mentioned groove be shaped as rectangle or ellipse.
The energy-saving ripple radiator of oil-immersed type transformer of the present utility model adopts the mode of two-sided welding to be welded on the relevant position of oil-immersed type transformer fuel tank, the corrugated plating number of its ripple radiator can be determined according to the length of ripple radiator, in an oil-immersed type transformer fuel tank, the quantity of ripple radiator can be the 1-4 piece, and a ripple radiator is welded on a side of oil-immersed type transformer fuel tank.The corrugated plating number of ripple radiator and the piece number of corrugated-fin radiator should require with the heat radiation of oil-immersed type transformer to be complementary.
The beneficial effects of the utility model: the energy-saving ripple radiator of oil-immersed type transformer of the present utility model is compared with existing oil-immersed type transformer ripple radiator, the former is better than latter intensity, radiating effect is better, oil-immersed type transformer uses the electrical loss of the energy-saving ripple radiator of this oil-immersed type transformer lower, energy-saving effect is better, when higher and oil pressure is big in the oil temperature of transformer, is difficult for two serious dilatancies of metallic plate of emersion wave card, use safer, better effects if.

Fig. 2 is the A-A section among Fig. 1;
Fig. 3 is the left view of Fig. 1.
Embodiment
Below by embodiment, the utility model is further described.
As Fig. 1, Fig. 2, shown in Figure 3, the energy-saving ripple radiator of a kind of oil-immersed type transformer comprises corrugated plating 6, oil inlet and outlet 2, corrugated plating upper end welding edge 4, corrugated plating lower end welding edge 7, fillet 1, is provided with groove 3 at the middle part of corrugated plating 6.Two groove 3 symmetries in same corrugated plating 6, the distance of two grooves 3 in same corrugated plating 6 can be the 3-8 millimeter.Between corrugated plating 6, be welded with reinforcement 5.Described groove 3 be shaped as rectangle or ellipse.The distance of two grooves 3 in same corrugated plating 6 should be selected a certain value according to designing requirement in the 3-8 millimeter, generally, the distance of two grooves 3 of the ripple radiator of small-sized oil-immersed type transformer is less, and the distance of two grooves 3 of the ripple radiator of medium-sized oil-immersed type transformer is bigger.
The energy-saving ripple radiator of oil-immersed type transformer of the present utility model is one time punching molded by forcing press and assembling die, thereafter by manually corrugated plating upper end welding edge 4, corrugated plating lower end welding edge 7 being welded.During use, fillet 1 adopts the mode of two-sided welding to be welded on the relevant position of oil-immersed type transformer fuel tank.
