The forced accelerated circulation transformer comprises a transformer oil tank and cooling pipes, wherein an iron core winding is arranged in the transformer oil tank. The forced accelerated circulation transformer is characterized in that the distance between the upper part of the iron core winding and an upper cover of the transformer oil tank is less than one fourth of the height of the transformer oil tank, a transverse partition plate extending inwards is arranged on the side wall of the transformer oil tank, the connection position of the transverse partition plate and the side wall of the transformer oil tank is higher than the top of the iron core winding, an encircled plate of which the lower part is spaced apart from the bottom of the transformer oil tank encircles the winding, the upper-end edge of the encircled plate and the inner edge of the transverse partition plate are connected in a crossed way, channels are formed in the space between the encircled plate and the winding, the encircled plate and the transverse partition plate are both hot poor conductors, the two ports of each cooling pipe are respectively arranged above and below the transverse partition plate and are communicated with the interior of the transformer oil tank, and the cooling pipes are integrally in a G shape. By the forced accelerated circulation transformer, heat dissipation area is large, convective circulation speed is fast, the iron core winding is arranged at a low-temperature oil region, and thus, the transformer is ensured to work in a stable temperature environment.
Description
Technical field
The present invention relates to a kind of power industry equipment transformer, more particularly to a kind of interior isolation runner pressure acceleration circulation
Transformer.
Background technology
China is vast in territory, and power delivery networks gather, and is required to transformer in the end of network to carry out voltage turn
Change.To produce heat in the transformer course of work, temperature is too high to affect the efficiency of voltage conversion, cause the increasing being lost,
So the design of transformer is all paid much attention to heat dispersion, existing transformer is typically all to adopt radiating tube, and radiating tube is upper and lower
Two ends respectively with the upper and lower UNICOM of oil tank of transformer inner space, constitute closed circuit, whole closed circuit is less than
The height of oil tank of transformer, the transformer oil density of different temperatures is different, and the oil temperature of transformer oil is by upper in whole closed circuit
Successively lower downwards, that is, upper strata temperature is higher than lower floor's temperature, and existing transformer core winding and transformer oil box cover
Spacing is less, thus can still have part iron core winding to be immersed in the higher oil reservoir of temperature, affects radiating, affects work effect
Rate, these still await technology solution.
The content of the invention
In order to solve the above problems, the invention provides isolation runner is forced to accelerate circulating transformer in a kind of.
The technical solution used in the present invention is：Isolation runner is forced to accelerate circulating transformer, including transformer oil in a kind of
Case and radiating tube, are provided with iron core winding in oil tank of transformer, it is characterised in that iron core winding top and transformer oil box cover
Spacing is not less than a quarter of oil tank of transformer height, and oil tank of transformer side wall is provided with the diaphragm plate of inside stretching, extension, tabula
Plate, higher than iron core winding top, is provided with bottom and possesses with transformer oil bottom with oil tank of transformer side wall link position around winding
The coaming plate of spacing, coaming plate upper end-face edge crosses with diaphragm plate inward flange and is connected, and spacing is possessed between coaming plate and winding and forms runner, encloses
Plate and diaphragm plate are the non-conductor of heat, and two ports of radiating tube are located at respectively diaphragm plate and join with oil tank of transformer inside up and down
Logical, radiating tube is in integrally G types.
Further, the radiating tube is helix tube.
Further, the coaming plate and diaphragm plate are two-layer, and two-layer compartment possesses spacing, and space is close in the spacing
Envelope space.
Further, the spacing between the coaming plate and winding is 0.5 centimetre to 1.5 centimetres.
The present invention forms a narrowed flow path upwards between coaming plate and iron-core coil, and iron-core coil transfers heat to stream
Transformer oil in road, transformer oil is diminished rapid increase by heat density, and the fluid in runner can quickly substitute, and increases convection current
Speed effectively improves radiating efficiency, while radiating tube of the present invention is G types, anti-upwards again after extending downwardly, length increases radiating surface
Product is increased, and the fluid being back between oil tank of transformer and coaming plate further can radiate by transformer oil box body, coaming plate with
Diaphragm plate is that the non-conductor of heat avoids backflow transformer oil from heating, and makes oil tank of transformer bottom oil temperature minimum, and iron core winding
Below oil tank of transformer upper height a quarter, in relatively low oil temperature region, it is ensured that transformer is in a stable temperature
Work under degree environment.

Fig. 1 is the overall schematic of the embodiment of the present invention one.
Fig. 2 is the cross-sectional schematic of the embodiment of the present invention one.
Reference:1 oil tank of transformer；2 radiating tubes；3 iron core windings；Cover on 4；5 diaphragm plates；6 coaming plates；7 runners.
Specific embodiment
The embodiment of the present invention one as shown in Figure 1, 2, force to accelerate circulating transformer to be provided with transformer oil by the interior isolation runner
Case 1 and radiating tube 2, are provided with the spacing of iron core winding 3, iron core winding top and transformer oil box cover 4 not in oil tank of transformer
Less than a quarter of oil tank of transformer height, top retains high temperature oil and takes space in, and oil tank of transformer side wall is provided with inwardly
The diaphragm plate 5 of stretching, extension, diaphragm plate, higher than iron core winding top, around winding bottom is provided with oil tank of transformer side wall link position
With the coaming plate 6 that transformer oil bottom possesses spacing, coaming plate upper end-face edge crosses with diaphragm plate inward flange and is connected, between coaming plate and winding
Possess spacing and form runner 7, the spacing between coaming plate and winding is 0.5 centimetre to 1.5 centimetres, and coaming plate and diaphragm plate are heat not
Good conductor, such as plastic cement or bakelite, two ports of radiating tube respectively be located at diaphragm plate up and down with oil tank of transformer inside UNICOM, dissipate
Heat pipe is in integrally G types.
The present invention forms a narrowed flow path upwards between coaming plate and iron-core coil, and iron-core coil transfers heat to stream
Transformer oil in road, transformer oil is diminished rapid increase by heat density, and the fluid in runner can quickly substitute, and increases convection current
