Description
Technical field
The present invention relates to a kind of heat dissipating method of transformer room, belong to the power station technology field.
Background technology
In urban electricity supply, because security needs, many transformers or reactor all are mounted in indoor (in the building).In recent years, because the demand that urban look is beautified, reduced ambient noise and isolates electromagnetic radiation, transformer and reactor are arranged in the basement, in the especially underground confined chamber, become the part of underground substation.Can produce a large amount of heats because transformer is in service, 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 increase, and cause increasing of transformer oil and winding temperature rise, influence the useful life of transformer, therefore the heat that transformer will be produced is from indoor, particularly be dispersed in the basement outdoor, to reduce indoor environment temperature and to ensure the safe operation of transformer.Present existing transformer room heat dissipating method has: natural draft heat radiation, forced ventilation heat radiation, water cooling, indoor refrigeration, the heat radiation of top set formula fuel tank etc.These heat dissipating methods all exist not enough under certain condition; Forced ventilation heat radiation, water cooling, indoor refrigeration need consumes energy or water source, and produce noise; The natural draft heat radiation is difficult satisfies the heat radiation requirement of underground transformer room or airtight transformer room, and simultaneously, the existence of ventilation and heat window is unfavorable for noise and electromagnetic radiation that isolating transformer produces, also causes the water inlet of subway transformer chamber easily.
Top set formula fuel tank heat dissipating method, transformer places indoor, and the heat radiation fuel tank places top layer outside the transformer room, carries out the transformer oil cycle heat exchange by oil pump.The main deficiency of this heat dissipating method is, the fuel tank oil pressure is big, seepage oil easily, and fuel tank requirement of strength height is with oily many costs height; Oil pump has noise, power consumption, influence heat radiation during damage; Airtight indoor environment temperature is still higher; Outdoor have a heat radiation fuel tank, is unfavorable for fire safety etc.
Summary of the invention
The objective of the invention is provides a kind of heat dissipating method that utilizes the transformer room of hot pipe technique, especially underground airtight transformer room in order to overcome the shortcoming of the used heat dissipating method in existing transformer room.
The heat pipe that is used to dispel the heat is the very high pipe of pyroconductivity, is commonly called as Super-conductive conduit.In sealed at both ends and evacuated pipe, inject an amount of hydraulic fluid, as acetone, ethanol, pure water etc., the liquid that is under the vacuum condition is vaporizated into steam from the endotherm section heat absorption, and heat release was condensed into liquid after steam arrived at the far-end radiating segment at a high speed, and the liquid of condensation prolongs tube wall and is back to endotherm section; Heat pipe is exactly evaporation heat absorption and the condensation heat release that utilizes low boiling hydraulic fluid in the vacuum, and is more than and so forth, with huge heat by the pipeline of small bore very, by the endotherm section efficient transfer to radiating segment.25 millimeters of diameters, the heat pipe that length is 1～10 meter, its heat conduction power can reach 1～10 kilowatt.
Technical scheme of the present invention is: a kind of heat dissipating method of transformer room, be characterized in, at least one group of heat pipe of being made up of endotherm section, radiating segment and adiabatic section is deep in the transformer room that transformer or reactor are housed by outdoor, wherein endotherm section places indoor, radiating segment places outdoor, the adiabatic section places part through walls, by airborne heat in the endotherm section absorption chamber, is sent to radiating segment and is dispersed in the outdoor air naturally.
Described every group of heat pipe is made up of at least one heat pipe.
The endotherm section of described at least one group of heat pipe is inserted in the interior oil of oil tank of transformer or is inserted in the liquid of the heat accumulator that soaks transformer, and absorbing heat and be sent to radiating segment by heat pipe is dispersed in the outdoor air.Described heat accumulator can be a plurality of little heat accumulator that is installed in the oil tank of transformer side.Heat pipe heat radiation ability in inserting transformer oil is enough, or the heat pipe heat radiation ability in the thermal-arrest tank liquor inserted can be saved the described heat pipe that room air is dispelled the heat when enough.
Heat pipe to the room air heat absorption fills low-temperature working liquid, and the effective operating temperature range of air heat absorption heat pipe is 0 ℃～80 ℃; Heat pipe to transformer oil and the heat absorption of thermal-arrest tank liquor fills the normal temperature working solution, and effective operating temperature range of oil heat absorption heat pipe is 40 ℃～160 ℃.
When needing further to increase outdoor heat pipe heat radiation ability, adopt radiating segment heat pipe water is drenched cooling or adopts the forced air cooling method.
When the transformer room is basement, can contain soil horizon on the basement top wall, transformer room's top wall and soil horizon are passed in described heat pipe adiabatic section.
Utilize the heat dissipating method of the transformer room of hot pipe technique, especially underground airtight transformer room, its beneficial effect is, outdoor radiator does not have oiling, and safety is fire prevention easily, and the transformer indoor environment temperature is low, the personnel's of being beneficial to inspection of entering the room, to transformer heat radiation cooling fully, use oily cost low less, need not oil pump, energy isolating transformer noise and electromagnetic radiation in the time of energy savings improve environment and beautify the environment.
