Abstract

A transformer heat pipe heat dissipation device comprises: the transformer oil tank is characterized in that a heat pipe element is inserted on the wall of the oil tank or the oil tank cover, a condensing section of the heat pipe element is provided with fins, and the heat pipe element can also be inserted into the oil tank of the independent heat dissipation device of the transformer. The heat pipe element can rapidly transfer heat in the oil tank to keep the oil temperature stable, thereby achieving the purposes of improving output and prolonging the service life.

Description

The heat-pipe radiating apparatus of transformer
The present invention relates to a kind of heat-pipe radiating apparatus of transformer.
The type of cooling of transformer mainly contains following several both at home and abroad at present: the cooling of (1) oil immersed type natural air; (2) oil immersed type air cooling; (3) forced oil circulation water-cooling but; (4) forced oil-circulation air cooling; (5) forced oil-circulation guiding cooling; (6) internal water cooling but; (7) evaporative cooling.Above-mentioned these types of cooling all have certain limit, have limited bigger capacity of transformer and more high-tension realization, because inventory charge, operation is complicated, condition influence such as temperature control and cooling difficulty development of electric power industry.
The objective of the invention is to utilize advanced hot pipe technique, design a kind of heat-pipe radiating apparatus of transformer.
Heat pipe is a kind of heat transfer element with high thermal conductivity, and it is than high times of the capacity of heat transmission of the best metallic conductor, even tens times, it has the thermal transmission coefficient height, the adaptive temperature scope is wide, and transfer of heat is big, simple structure, be suitable for strengthening heat-transfer surface, safe and reliable, do not need to safeguard, do not need power, the pressure loss is little, advantages such as long service life.This heat-pipe radiating apparatus is contained in does not need power on the transformer, can automatically insulating oil temperature in the transformer be kept stable, thereby make transformer stable operation, but full load or overburden operation and do not influence transformer useful life has good fail safe, reliability, automaticity and economic worth.
The heat-pipe radiating apparatus of transformer is the improvement to existing common transformer, it comprises oil tank of transformer, conservator is housed on fuel tank, fuel tank cap is housed on the fuel tank, low tension terminal and high tension terminal are housed on fuel tank cap, coil and iron core are housed in the fuel tank, insulating oil also is housed in the case, it is characterized in that on oil tank wall or on the fuel tank cap heat-pipe elements is inserted in the insulating oil, this heat-pipe elements can be rapidly conducts the heat of insulating oil in the fuel tank to keep insulating oil temperature to stablize, condensation segment at heat-pipe elements is equipped with fin, to accelerate cooling rate, also this heat-pipe elements can be inserted in the fuel tank of independent heat abstractor of transformer.
The present invention and existing its advantage of transformer comparison are:
1. conductive coefficient height, the conductive coefficient of other type of cooling of heat-pipe elements heat conduction cooling raio is high 10 times;
2. heat-transfer rate is fast, fast about 50 times than other medium heat conduction speed of the heat-transfer rates of heat pipe;
Therefore 3. the adaptive temperature scope is wide, and 50~300 ℃ of its adaptive temperature scopes can be made the transformer of the big voltage of big capacity;
4. simple structure is easy for installation, and element is installed easily, does not need special connection;
5. safe and reliable, do not need to safeguard.Heat-pipe elements is not as long as the just heat conduction rapidly of contact thermal source produces any side effect;
6. do not need outer power, the pressure loss is little, energy savings;
7. long service life, heat pipe useful life and transformer are synchronous useful life, are generally about 20 years.
8. improve and exert oneself, owing to control automatically, adjusting heat up, it exerts oneself 20~26% than the raising of same specification transformer.
Description of drawings:
Fig. 1 is the transformer device structure schematic diagram that has heat-pipe radiating apparatus
Fig. 2 is the heat-pipe radiating apparatus of transformer.
Number in the figure: 1. oil tank of transformer; 2. insulating oil; 3. conservator; 4. low tension terminal; 5. high tension terminal; 6. heat-pipe elements; 7. iron-core coil; 8. fuel tank cap; 9. the fuel tank of the independent heat abstractor of transformer.
Below in conjunction with accompanying drawing embodiment of the present invention are described further:
The transformer (see figure 1) of transformer heat-pipe radiating apparatus of the present invention comprises: oil tank of transformer 1, on fuel tank, be provided with conservator 3, fuel tank cap 8 is arranged on fuel tank 1, low tension terminal 4 and high tension terminal 5 are housed on this case lid 8, coil and iron core 7 and insulating oil 2 are housed in this fuel tank, it is characterized in that being inserted with on this fuel tank 1 wall or on fuel tank cap 8 in the heat-pipe elements 6 insertion insulating oils 2, on the condensation segment of heat-pipe elements 6, fin is housed, heat-pipe elements 6 can pass the heat in the insulating oil rapidly, oil is warm to be stablized to keep, thereby improves exerting oneself of transformer.The condensation of this heat-pipe elements can be taked natural cooling simultaneously and force cooling, to accelerate the cooling rate of insulating oil.Also this heat-pipe elements 6 can be inserted (see figure 2) in the fuel tank 9 of independent heat abstractor of transformers.This kind heat-pipe radiating apparatus also can be used on other electric equipment of needs coolings such as appliance switch, compensator.
