Abstract
A distribution transformer comprises a transformer body, a heat dissipating device and a transformer oil tank with a cover, wherein the transformer body is positioned in the transformer oil tank filled with transformer oil. The distribution transformer is characterized in that the heat dissipating device is a heat pipe; the heat pipe passes through the cover of the oil tank from the upper part of the oil tank and is inserted into the oil tank. Heat in the oil tank is transferred out through the heat pipe quickly to keep oil temperature stable, and the distribution transformer has characteristics of high heat transfer efficiency, small size and long service life.
Description
Technical field
The utility model relates to a kind of transformer, relates in particular to a kind of distribution transformer.
Background technology
Transmit a kind of static electrical equipment of AC energy in the distribution transformer assignment electric system according to law of electromagnetic induction conversion alternating voltage and electric current.Usually be contained on the electric pole or in the distribution substation, generally can voltage be reduced to about 400 volts from 6～10 kilovolts and import the user.
The transformer heating situation that is in operation is more serious, and distributing of heat makes progress.At present, distribution transformer in order to reduce manufacturing cost, adopts the ventilation and heat structure with regard to machine body structure basically.Transformer is owing to adopt gilled radiator; Make self laterally bulky; Transportation and maintenance are all very inconvenient; And the gilled radiator radiating efficiency is lower, and transformer is often because oily temperature rise is too high, causes transformer oil decreasing insulating, oil flow electrification, coil is aging even cause accidents such as fire for transformer, blast.Therefore improve the Natural Oil Circulation Power transformer cooling structure, improve its cooling effectiveness, no matter from energy-saving and cost-reducing, still prolong distribution transformer useful life, reduce hot accident aspect, all will bring the huge social economic benefit.
The utility model content
The purpose of the utility model is in order to solve the deficiency of above-mentioned prior art; A kind of technical scheme is provided, utilizes heat pipe that distribution transformer is dispelled the heat, improved cooling effectiveness with efficient heat transfer; Improved the heat dispersion of distribution transformer; Occupied ground is few, and volume is little, prolongs the useful life of transformer.
A kind of distribution transformer of the utility model comprises transformer body, heat abstractor and is provided with the oil tank of transformer of case lid that the device body is positioned at the oil tank of transformer that is full of transformer oil, it is characterized in that heat abstractor is a heat pipe.
As preferably, heat pipe is the case lid through fuel tank from fuel tank top, inserts in the fuel tank.Heat pipe is positioned at the transformer top, replaces the sidepiece that original fin is positioned at fuel tank, has reduced the place of the installation of transformer greatly, and weight reduction simultaneously improves radiating effect, to reduce volume.
Heat pipe structure and operation principle: typical heat pipe is made up of shell, wick and end cap.Fill with an amount of hydraulic fluid after heat pipe is pumped into negative pressure, make in the wick capillary porous material of being close to inside pipe wall to seal behind the full of liquid.One end of pipe is evaporation section (bringing-up section), and the other end is condensation segment (cooling section), can arrange the adiabatic section according to application need two sections centres.When an end of heat pipe is heated, the vaporization of liquid evaporation in the capillary wick, steam flows to the other end and emits heat and condense into liquid under small pressure.Liquid leans on the effect of capillary force to flow back to evaporation section along porous material again, so circulates endlessly, and heat reaches the other end from an end of heat pipe.Can as required this heat pipe be made various shapes, its circulation power is that capillary materials and liquid combine formed capillary force.
As preferably, heat pipe is a gravity assisted heat pipe.
When heat pipe is in the ground gravity field, circulating of its working medium will mainly receive gravity effect.When its inclination or when vertically placing, evaporating section is in the below, and then the liquid working substance of condensation can be back to evaporation section by gravity up, Here it is gravity assisted heat pipe.Gravity assisted heat pipe and premium properties gravity assisted heat pipe thereof are to rely on the gravitational field effect of intraductal working medium and form and circulate.Owing to not be used in and add wick in the pipe; Its manufacturing cost reduces greatly; And its working medium can water, because glassware for drinking water has good physical property and economy heat pipe working temperature generally between O～25O ℃, so it has obtained using widely in practical engineering application.It has following good characteristic: (1) the very high inner main vapour of hydraulic fluid, liquid phase leaned on of thermal conductivity gravity assisted heat pipe becomes heat transfer, and thermal resistance is very little, therefore has the very high capacity of heat transmission.Test shows that gravity assisted heat pipe is compared with the radiating efficiency of the identical copper pipe of physical dimension, and the efficient raising reaches about 2O times.(2) simple in structure, easily manufactured, with low cost, and the life-span is long, can use about 2O generally speaking.(3) start-up temperature is low, when thermal source is 3O ℃, can start, and the temperature difference is high-power more high more, therefore is fit to very much be applied in the transformer.
The beneficial effect of the utility model is: the utility model can be gone out the heat transferred in the fuel tank rapidly through heat pipe, to keep the oil temperature stable, has heat transfer efficiency height, the less characteristics of volume, has prolonged the useful life of transformer.
Description of drawings
Below in conjunction with accompanying drawing and embodiment utility model is further specified.
Fig. 1 is the contour structures sketch map of the utility model embodiment.
Among the figure: 1, fuel tank 2, case lid 3, oil tank of transformer 4, gravity assisted heat pipe 5, bushing 6, low-tension bushing.
Embodiment
As shown in Figure 1; The utility model embodiment is a kind of distribution transformer; Be all-sealed structure; Comprise transformer body, heat abstractor and be provided with the oil tank of transformer 1 of case lid 2, the device body is positioned at the oil tank of transformer 1 that is full of transformer oil, and case lid 2 is provided with bushing 5, low-tension bushing 6, oil fuel tube 3 and gravity assisted heat pipe 4.Gravity assisted heat pipe 4 is a heat abstractor, and gravity assisted heat pipe 4, inserts in the fuel tank 1 through the case lid 2 of fuel tank 1 from fuel tank top.Gravity assisted heat pipe 4 is positioned at the transformer top, replaces the sidepiece that original fin is positioned at fuel tank, has reduced the place of the installation of transformer greatly, and weight reduction simultaneously improves radiating effect, to reduce volume.Transformer when transformer upper strata oil temperature produces the temperature difference, can be gone out the heat transferred in the fuel tank rapidly through gravity assisted heat pipe 4 in use; To keep the oil temperature stable; Have the heat transfer efficiency height, volume is less, the characteristics that cost is low have prolonged useful life of transformer.Gravity assisted heat pipe 4 is made simply than other kind heat pipe low price, places several and gets final product.Every heat pipe all is an absolute construction, does not have the leakage of oil problem, and the life-span is long.Gravity assisted heat pipe himself is an autonomous system to good environmental adaptability, can make arbitrary shape, is fit to be applied in the various environment, and this is its prime advantage place just.
The foregoing description is the explanation to the utility model, is not the qualification to the utility model, and any structure after simple transformation on the utility model basis all belongs to the protection range of the utility model.
