Product Details

Dry type transformer

SCB Dry Type power transformer


The reel core fully sealed distribution transformer is a new generation of low noise and low loss transformer developed in recent years. Its iron core has no joint, greatly reduces the no-load loss and no-load current, reduces the no-load current by 60%~80%, the high and low coils are continuously coiled on the core column, the winding is tight, the concentricity is good, and the product is enhanced more. Anti-theft performance. The noise decreased by more than 10 decibels. The temperature rise is low 16-20K. Because of the continuous winding of iron core (cross section is pure circle), the orientation loss of silicon steel sheet is fully utilized, and the no-load loss is reduced by 20%~30%.

 

The low voltage winding with capacity in the 630~2500kVA enclosure is made of cylinder or spiral structure with high mechanical strength and balanced ampere distribution. The product has good short circuit resistance.


The positioning structure is added to the body so that it does not produce displacement during the transportation process, and all fasteners are equipped with fastener nuts to ensure that the fasteners are not loose during the long run of the product and meet the requirements of the non core lifting.


The product surface is painted, primed and topcoat after degreasing, rust removing and phosphating. It can meet the special requirements of metallurgy, petrochemical system and wet dirty area.This series of products has beautiful appearance, small size, and can reduce the installation area. It is an ideal free maintenance quality product.


Structural Characteristics:

Cast-foil Coil:

Adopting the entire section of copper foil, together with the F-class turn insulation, low voltage winding is wound by the special low-voltage foil winding machine. The foil coil resolves such understanding problems as large short-circuit stress, uneven ampere turn, poor heat dissipation, existing the winding spiral angle as well as unsteady manual welding quality due to low voltage and large current coil winding products. At the same time, the winding end in our company is treated with resin potting, solidification to make shape, moisture-proof and anti-fouling, the lead copper platoon is automatically welded by argon arc welding.

 

Temperature Control Device:

the transformer adopts BWDK series of signal thermometer. The temperature components, are embedded in the upper half of the low-voltage coil, can automatically detect and dynamically display the work humidity of phase coils and also have the functions of over-temperature alarm and trip.

Product details

 

 

Low loss:the product no-load loss is 20% lower than the Sc (B) 11 type product with an

excellent energysaving effect, economic efficient operation and without maintenance.

Low noise:the product noise level is 10-15 db lower than the existing professional standard

JB/T10088- 2004Sound Level of 6- -220KV Transformer

Low partial discharge:resin mixture adopts foreign leading-edge mixing method and film type

vacuumdeaerator to evenly mix the mixture and remove the bubble in the bottom part of mixture.

The product hasa low partial discharge which can be controlled at 5PC. Both high voltage and low

voltage coils can bepoured in vacuum pressure so as to enable a encapsulating of resin insulation

and immersion amonglayers and inter-tums. The poured part has a compact solidity staicture with

anti-flaming, anti explosionand environmental protection features.
Glass fiber and other raw materials of winding coil have self- extinguishing property and will not

producearc due to short circuit. Resin will not produce harmful gas under high temperature.

SCOPE of application

 

None of the dry-type transformers we see today are installed in a separate, tightly enclosed room, as in

the oil-immersed type, but only in a relatively dry and clean room. In addition to this, it is also very convenient

to transport or carry, no matter what kind of transport vehicles, trains, cars or other non-motor vehicles can be,

but it is best to keep the car dry, clean and the product itself in good packaging. Practice has proved that really

good products will always be more and more marketable. As dry-type transformers have very good fire-proof

performance and are easy to install and maintain, they are also used more and more widely Especially in the

modern commercial downtown, residential areas, hospitals, airports, stations, subways, theaters, schools,

public places and other places with high requirements on fire protection.
