Description

A kind of transformer room of heat pipe heat radiation

Technical field

The utility model relates to a kind of transformer room of heat pipe heat radiation, belongs 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/T15164-1994 " 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 be adopt natural draft, with heat radiations such as forced ventilation device, water-cooling apparatus, indoor refrigerating plant, top set formula tank mountings.These heat abstractors all exist not enough under certain condition; Devices such as forced ventilation, water cooling and indoor refrigeration all need to consume the more energy, but also produce noise; Difficulty satisfies the heat radiation requirement of underground transformer room or airtight transformer room to adopt natural draft to dispel the heat, and 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 abstractor, 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 abstractor 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 purpose of this utility model is in order to overcome the shortcoming of existing transformer room's heat radiation equipment therefor, a kind of transformer room that utilizes heat pipe heat radiation to be provided.

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.

The technical solution of the utility model is: a kind of transformer room of heat pipe heat radiation, be characterized in, the transformer room that transformer or reactor are housed is equipped with at least one group of heat pipe of being made up of endotherm section, radiating segment and adiabatic section, described every group of heat pipe 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, be sent to radiating segment and be dispersed in the outdoor air naturally.Described every group of heat pipe is made up of at least one heat pipe.

Have at least the endotherm section of one group of heat pipe to be inserted in the oil in the oil tank of transformer in the described heat pipe heat or be inserted in the liquid of the heat accumulator that soaks transformer, absorb heat or the heat in the absorbing sets heat channel liquid in the transformer oil and be sent to radiating segment by heat pipe and be 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, radiating segment heat pipe addition water is drenched cooling device or forced air cooling device.

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 transformer room of heat pipe heat radiation, especially underground airtight transformer room heat pipe heat radiation, 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.
