Description
Technical field
The utility model relates to the aeration-cooling technology of transformer and reactor, particularly relates to a kind of transformer reactance device ventilation unit.
Technical background
Along with fast development of national economy, China is increasing to the demand of electric power and power equipment, and the requirement of falling this section consumption is also more and more higher.Transformer and reactor are as main power equipment, and output constantly increases.How to reduce the loss of transformer and reactor, more and more be subjected to people's attention.Because the copper loss W=I of transformer and reactor
2R.Wherein, I is an electric current, and R is a coil resistance.Resistance raises with temperature and increases, so, reduce the copper loss that coil temperature can reduce transformer and reactor effectively.
Summary of the invention
The purpose of this utility model is to provide a kind of can improve air blast transformer or reactor radiating efficiency, reduces the transformer reactance device ventilation unit of coil temperature.
For achieving the above object, the utility model transformer reactance device ventilation unit comprises that the upper end that is sleeved on the fuselage periphery has the cabinet that air outlet, lower end have air inlet, is equipped with the air channel dividing plate of one or more layers middle part perforate between fuselage and cabinet.So design can prevent that littler fuselage and the cabinet clearance channel of cooling air selection resistance that enters from the air port from flowing to air outlet, makes cooling blast flow through fuselage by force, fully carries out heat exchange with fuselage.Be applied to air blast transformer or reactor, have and to significantly improve radiating efficiency, reduce the advantage of coil temperature.
As optimization, described air channel dividing plate is 2 layers that distribute up and down.So design is simple in structure, convenient being suitable for.
As optimization, ventilation gap is all arranged between one deck air channel dividing plate and cabinet and the fuselage below wherein, above ventilation gap is arranged between the insulating cylinder of one deck air channel dividing plate and fuselage.So design, can be on fuselage the reasonable distribution cooling air quantity, avoid bottom cold wind too much, upper strata cold wind is very few.
As optimization, above assemblage gap is arranged between one deck air channel dividing plate and the cabinet.Make things convenient for installation and maintenance.
As optimization, above one deck air channel dividing plate the sagging soft cord of nature is installed at the assemblage gap place.Described soft cord preferably polytetrafluoroethylene Polypropylence Sheet.When motor exhaust was worked, suction picked up the plastics cord, and the air-flow utilance has been improved in space around blocking.Assemblage gap mainly is for the lead-in wire folder is installed.
Be that example is described further below with the transformer, all structures are suitable for too for reactor.
Between cabinet and transformer, add two-layer dividing plate:
1. according to common way, transformer is placed in the cabinet, and during the blower fan air draft at cabinet top, owing to do not adopt the sealing measure, a large amount of cryogenic gases directly flow to the top from the passage on transformer fuselage next door and drained, and do not play the effect of cooling transformer.Cause radiating efficiency lower.After increasing air channel, upper strata dividing plate, cold air is forced to import dividing plate middle part perforate, improved the utilance of cold air.
2. according to common way, the transformer bottom is because nearer from blower fan, and air themperature is lower simultaneously, and the coil radiating condition is good, and temperature is lower.And the transformer middle and upper part, owing to air themperature has raise, and away from hair-dryer, air turbulence, radiating condition is relatively poor, temperature drift.Increase lower floor's air channel dividing plate, a part of cold air is diverted to coil top, also improved the state of air-flow simultaneously, improve the efficient of heat radiation.
The utility model transformer reactance device ventilation unit is applicable to single-column and three posts and multicolumn transformer and reactor, in requisition for opening one, three or more hole.In the practical operation, according to installation requirement, should be lead-in wire, associated components slot millings such as folder.For the ease of installing, above one deck air channel dividing plate around and also can reserve the space of 20mm between the cabinet to 100mm, fix four narrow plastics cords, because size reduces, and is easy for installation, when motor exhaust is worked, suction picks up soft cord, and the air-flow utilance has been improved in space around blocking.Circularhole diameter Φ in the middle of the dividing plate of top one deck air channel can press 80% to 120% of external insulation bucket diameter according to designing requirement and change.If inner coil temperature drift in the design, Φ reduces, and then increases on the contrary.Top one deck air channel dividing plate is regulated in 0 to 20% coil height scope apart from a apart from coil top.Circularhole diameter Φ in the middle of the dividing plate of following one deck air channel can press 100% to 120% of external insulation bucket diameter according to designing requirement and change.Following one deck air channel dividing plate is regulated in 50% to 75% coil height scope apart from the distance h of coil bottom; Slit between following one deck air channel dividing plate and the casing is regulated in 1% to 30% scope of casing length and width.Concrete size is adjusted according to the coil temperature distribution curve.
After adopting technique scheme, the utility model transformer reactance device ventilation unit has only increased several air channel dividing plates, has simple in structurely, can effectively improve the radiating efficiency of coil, can reduce the advantage of coil temperature rise significantly.
