Product Description

Application

Dry-type transformers are widely used in local lighting,high-rise buildings,airports,terminals,CNC machinery
equipment and other places,simply dry-type transformer refers to the core and winding is not immersed in the
insulation oil transformer.Cooling is divided into natural air cooling(AN) and forced air cooling(AF).When natural
air cooling,the transformer can be rated capacity under long-term continuous operaton.Forced air cooling,the
transformer ouput capacity can be increased by 50%.Applicable to intermittent overload operation,or
emergency overload operation.

Structure features:

1.Security,fire proof,pollution-free,can be directly run on the load center;
2.Using the domestic advanced technology,high mechanical strength,high anti short-circuit ability,small partial
discharge,thermal stability,gigh reliability,long service life;
3.Low loss,low noise,energy-saving effect is obvious,maintenance-free;
4.Good cooling performance,strong overload capacity,forced air cooling can increase the running capacity;
5.Moisture-proof performance good,adapt to high humidity and other harsh environments;
6.Dry-type transformers can be equipped with a complete temperature detection and protection system.Using
intelligent signal temperature control system,can automatically detect and tour display three-phase windings
of their working temperature,can automatically start,stop the fan,and alarm,trip and other functional settings;
7.Small size,light weight,small footprints,low installation costs

Temperature control system:

The safe operation of dry-type transformer and its life depends largely on the reliability of transformer winding
insulation safety.

Cooling method:

Dry-type transformer cooling method is divided into national air cooling(AN) and forced air cooling(AF).With
natural air cooling,the transformer can be long-term continuous operation under rated capacity.Forced air
cooling,the transformer ouput capacity can be increased by 50%.It is suitable for intermittent overload operation
or emergency overload operation.Because when overload the load loss and impedance voltage increase
greatly,it is in non-economic running state,so it should not make it run continuously for a long time.

Technical parameters:

1.The frequency of use:50/60HZ;
2.No-load current:<4%;
3.Compression strength:20000 v/min No breadown;Test equipment:YZ1802 pressure tester(20ma)
4.Isolation grade:F(can be customized)
5.Insulation resistance:≤2M ohm test equipment:ZC25B a 4 megaohmmeter<1000V);
6.Connection mode:Y/Y,⊿/Y0,Yo/⊿,self-coupling(optional)
7.I00K;The coil allows temperature rise;
8.Cooling method;Natureal air cooling or temperature control automatic cooling
9.Noise coefficient: ≤30dB.
