Description

A kind of heat abstractor of transformer

Technical field

The utility model relates to a kind of transformer, particularly a kind of heat abstractor of transformer.

Background technology

Power transformer is widely used in various load center, along with life and industry to electric pressure and burden requirement more and more higher, and the uncertainty of the running environment of transformer own, causing transformer to dispel the heat becomes a stubborn problem more.How reducing costs under the prerequisite of control transformer temperature rise, become the pursuit of each transformer producer.Gilled radiator is generally used on Transformer, oil and oil have fin, flow in fin transformer oil, body is flowed back to from bottom after top natural circulation flows into cooling, if the transformer that fuel tank is larger just needs oil circulating pump to assist the flowing of oil, structure relative complex.

Utility model content

Utility model object: for the problems referred to above, the purpose of this utility model is to provide that a kind of structure is simple, heat radiation is good, can the heat abstractor of effective control transformer temperature rise.

Technical scheme: a kind of heat abstractor of transformer, comprise main oil inlet pipe, main flowline, heat radiation oil pipe, fuel tank, described heat radiation oil pipe is fixed around being wrapped in transformer body, the height point entrance location of described heat radiation oil pipe connects described main oil inlet pipe, the low spot exit position of described heat radiation oil pipe connects described main flowline, and described main oil inlet pipe, described main flowline are connected into described fuel tank.

Also comprise a flowline, described heat radiation oil pipe is at least two, every root is one-level, every root is the curved pipe of symmetrical connection, be placed in transformer body both sides, Gao Dian position, its two ends of curved pipe is the height point entrance location connecting described main oil inlet pipe, and middle low dot location is the low spot exit position connecting a described flowline, described flowline is communicated with the described heat radiation oil pipe of adjacent two-stage, and the described heat radiation oil pipe of final stage connects described main flowline.

Best, the described heat radiation oil pipe of final stage is horizontal straight tube, only as the pipeline collecting the rear transformer oil of cooling.

Described heat radiation oil pipe outside is provided with wire netting, plays the effect of security protection.

Beneficial effect: compared with prior art, the utility model has the advantages that: 1, lowered the temperature by conducting heat around the heat radiation oil pipe and air that are wrapped in transformer body by the transformer oil of high temperature in fuel tank, increases the contact area with air, improves radiating effect; 2, adopt multistage heat radiation oil pipe to introduce the transformer oil of high temperature simultaneously, and be pooled to final stage by every grade through cooled transformer oil and flow back to fuel tank again, the heat radiation of heat radiation oil pipe at different levels can not be bothered mutually, thus fast cooling, improve radiating effect; 3, arranging heat radiation vitta structure makes transformer oil lean on free gravity to flow, and mobility is excellent, improves radiating effect.

Fig. 2 is the left view omissive representation of Fig. 1;

Fig. 3 is final stage heat radiation oil pipe is the utility model structural front view of horizontal straight tube.

Embodiment

Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, these embodiments should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.

As illustrated in the accompanying drawings from 1 to 3, a kind of heat abstractor of transformer, comprises main oil inlet pipe 1, main flowline 2, heat radiation oil pipe 3, fuel tank 4, flowline 5, wire netting 6.

Heat radiation oil pipe 3 has many, and every root is one-level, and single heat radiation oil pipe 3 is the curved pipe of symmetrical connection, fixes around being wrapped in transformer body both sides.The Gao Dian position, two ends 7 of curved pipe is the height point entrance location connecting main oil inlet pipe 1, middle low dot location 8 is the low spot exit position connecting a flowline 5, be communicated with by a flowline 5 between the heat radiation oil pipe 3 of adjacent two-stage, the heat radiation oil pipe 3 of final stage connects main flowline 2, and main oil inlet pipe 1, main flowline 2 are connected into fuel tank 4.

Heat radiation oil pipe 3 outside is also provided with wire netting 6 safety protection functions.

The transformer oil of high temperature passes through main oil inlet pipe from fuel tank, flow into the heat radiation oil pipe of every grade, flow voluntarily to low from high wherein, the heat radiation oil pipe of final stage is finally pooled to from a flowline, temperature to be fallen apart in surrounding air thus cooling by transformer oil in flow process, and the oil of cooling flows back to fuel tank by the main flowline be connected with the heat radiation oil pipe of final stage again.

As shown in Figure 3, the heat radiation oil pipe 3 of final stage can also adopt horizontal straight tube, it does not have dividing of height, can not be connected with main oil inlet pipe, and only dispel the heat with upper level between oil pipe and be communicated with flowline, and be connected with main flowline, so that cooled transformer oil is pooled to after this can flow back to fuel tank smoothly, keep pipeline unimpeded.

The utility model improves radiating effect, control transformer temperature rise is mainly realized by following principle: 1, lowered the temperature by conducting heat around the heat radiation oil pipe and air that are wrapped in transformer body by the transformer oil of high temperature in fuel tank, increases and needs the transformer oil of cooling down and the contact area of air; 2, adopt multistage heat radiation oil pipe to introduce the transformer oil of high temperature simultaneously, and be pooled to final stage by every grade through cooled transformer oil and flow back to fuel tank again, the heat radiation of heat radiation oil pipe at different levels can not be bothered mutually, thus fast cooling; 3, arranging heat radiation vitta structure makes transformer oil lean on free gravity to flow, and mobility is excellent.
