Description
Technical field
The present invention relates to dry-type power transformer technical field, specially a kind of dry-type power transformer.
Background technology
Power transformer is one of power plant and the capital equipment of electric substation.The effect of transformer be it is various, not only
Can increase voltage electric energy be sent to electricity consumption area, moreover it is possible to voltage be reduced to it is at different levels use voltage, to meet the needs of electricity consumption, become
Depressor is the device for converting alternating voltage, electric current and impedance, when being connected with alternating current in primary coil, in iron core (or magnetic core)
Just exchange flux is generated, makes to induce voltage (or electric current) in secondary coil.Transformer is made of iron core (or magnetic core) and coil,
Coil there are two or more than two windings, wherein connecing the winding of power supply primary coil, remaining winding is secondary coil.
Dry-type power transformer is the very high dry-type transformer of a kind of electrical strength, mechanical strength, high-temperature capability.It is city
The quality product of electric network reconstruction prevents fires especially suitable for requirements such as skyscraper, airport, power station, commercial centers, is explosion-proof, moisture-proof
Important place.Dry-type transformer is widely used in local lighting, skyscraper, airport, the places such as harbour CNC mechanical equipments, letter
Single transformer for saying dry-type transformer just and refer to that iron core and winding are not immersed in insulating oil.The type of cooling is divided into natural air
Cooling (AN) and forced air cooling (AF).When natural air cooling, transformer can under rated capacity long-term continuous operation.Force wind
When cold, transformer output capacity can be improved 50%.Suitable for interrupted running overload or emergent accident running overload；Due to
Load loss and impedance voltage amplification are larger when overload, are in non-economy operating status, therefore should not be at and connect for a long time
Continuous running overload.
The type of power transformer is varied, common are oil-immersed power transformer and dry-type power transformer.Two
Kind is all power transformer, can all have the iron core for making magnetic circuit, make the winding of circuit.And maximum difference is " oily formula " and " dry
Formula ".That is the cooling medium of the two is different, the former is using transformer oil (also having other oil such as β oily certainly) as cooling
And dielectric, the latter are using air or other gases such as SF6 etc. as cooling medium.It is that handle is made of iron core and winding that oil, which becomes,
Device body be placed in the fuel tank that one fills with transformer oil.Dry change is often encapsulated iron core and winding with poured with epoxy resin,
Also have it is a kind of it is present with much be non-encapsulated type, winding impregnates special isolation paint etc. again with special insulating paper, plays anti-
Only winding or iron core make moist.
With the development of Chinese national economy, constantly sound and people's environmental consciousness the enhancing of national environmental protection regulation.It is dry
Formula transformer accelerates in city power distribution transformer portion, and the iron core of dry-type power transformer uses the high-quality crystalline substance of high magnetic conduction
Grain is orientated cold-rolled silicon steel piece, 45 ° of complete tiltedly stepping seams, and iron core uses special square tube pulling plate structure, stem to be tied up using insulating tape
It pricks, iron core surface uses special resin coating with moisture-proof antirust, effectively reduces no-load loss, no-load current and iron core noise,
Meanwhile requirement of the user to dry-type transformer manufacturing firm is also higher and higher.Existing dry-type transformer heat dissipation performance is poor, noise
The shortcomings of big.
