Abstract
The invention includes transformer, separate type heat pipe, and heat exchanger. Oil tank of the transformer and heat source box of the heat exchanger is interconnected. Transformer oil is as heat source of the heat exchanger. Heat sink box of the heat exchanger is as heat absorber of the separate type heat pipe, and heat absorption medium in the heat sink box is also as working fluid of heat pipe. Absorbing quantity of heat from transformer oil, heat absorption medium in heat sink generates steam. Through pipe, steam is transported to radiator, where condensed steam becomes liquid. Under action of gravity, through pipe, the condensed liquid returns back to the heat absorber so as to complete cyclic process: heat absorption and elimination, vaporization and condensation, steam transportation and returning liquid back. Advantages are: circular flow based on gravity without need of circulating pump so as to save energy and eliminate noise, no inference on insulation of transformer oil.
Description
Technical field
The present invention relates to a kind of transformer that adopts separate heat pipe to be shifted and to dispel the heat, belong to the transformer technology field.
Background technology
In the electric power transmission ﹠ distribution, because security needs, many transformers or reactor all are mounted in indoor.The demand that urban look is beautified, reduced ambient noise and isolates electromagnetic radiation, transformer and reactor often are arranged in the basement, in the especially underground confined chamber, become the part of underground substation.Transformer is in service can to produce a large amount of heats, IEC 354-1991 and GB/T 15164-1994 " oil-immersed power transformer load guide rule " show, the heat that transformer produces can make indoor environment temperature raise, and cause the increase of transformer oil and winding temperature rise, therefore influence the useful life of transformer, the heat that transformer will be produced is from indoor, particularly is dispersed in the basement outdoor, the heating that is about to transformer is displaced to other place and distributes, to ensure the safe operation of transformer.Present existing transformer displacement heat abstractor has: forced ventilation heat abstractor, water-cooling apparatus, indoor refrigerating plant, evaporation-cooled device, top set formula fuel tank heat abstractor, split type fuel tank heat abstractor, tubing hot-pipe heat abstractor etc.
There is deficiency in present transformer displacement heat abstractor aspect different.Forced ventilation heat abstractor, water-cooling apparatus, indoor refrigerating plant need consumes energy or water source, and produce noise; Evaporative cooling medium contacts with transformer insulated medium, and is influential to insulating; Top set formula fuel tank heat abstractor, the fuel tank oil pressure is big, easy seepage oil, fuel tank requirement of strength height, oil circulating pump is fragile, and noise is arranged, power consumption, outdoor heat radiation fuel tank is unfavorable for that fire safety is explosion-proof; Split type fuel tank heat abstractor floor space is big, is unsuitable for remote split displacement heat radiations such as basement, and outdoor fuel tank fin is unfavorable for fire-proof and explosion-proof; Tubing hot-pipe is used for remote the displacement when dispelling the heat, and single heat pipe transfer of heat is less, transfer canal is many, volume is big, cost is high.
Summary of the invention
The objective of the invention is in order to overcome the shortcoming of the existing used displacement heat abstractor of transformer, particularly overcome the shortcoming of the transformer of tubing hot-pipe displacement heat radiation, provide a kind of and utilize that separate heat pipe carries out at a distance, the transformer of natural circulation, big heat split displacement heat radiation, in particular for the transformer of basement.
The separate heat pipe that is used to dispel the heat comprises heat dump, radiator, steam transmitting pipe, liquid back pipe.Heat sink location is higher than the heat dump position, heat dump is communicated with into circulation circuit with radiator through steam transmitting pipe and liquid back pipe, in this circulation circuit, be evacuated and inject an amount of hydraulic fluid, as acetone, ethanol, pure water etc., the liquid that is in the vacuum is vaporizated into steam from the heat dump heat absorption, heat radiation is condensed into liquid steam arrives at the radiator of far-end through steam transmitting pipe after, and the liquid of condensation turns back to heat dump by gravity through liquid back pipe.Compare with tubing hot-pipe, the defeated vapour of separate heat pipe carries out at different pipelines with time liquid, defeated vapour and the resistance that returns the liquid reverse flow have been overcome, so the heat delivered ability of separate heat pipe greater than tubing hot-pipe, has the remarkable economical advantage when remote big heat is shifted heat radiation.The heat transmitting range of separate heat pipe can reach more than hundred meters, and through-put power can reach hundreds of kilowatts, does not need the supplementary energy driving that circulates.
