Product Description

SCB13 Dry type transformer

·Product introduction

Compared with model scb12 epoxy resin cast three-phase dry-type transformer, model scb13 dry-type transformer is a new upgrading generation product. Its no-load loss reduces by 5% compared with model scb12, showing significant energy-saving effect. Meanwhile, it is safe, fire-retardant, pollution-free, maintenance free and easy installation. With good moisture-proof performance, it can restart without pre-drying after shutdown. This model shows low loss, low partial discharge and low noise. Under forced air cooling, it can operate at 120% of rated load. Perfect temperature protection and control system provides reliable guarantee for the safe operation of the transformer.

·Structural features

1. Low partial discharge:

Adoption of leading mixing method and the membrane-type vacuum deaerator makes the mixture material evenly and eliminates the bubbles at the bottom of the mixture. The product demonstrates low partial discharge and can be controlled at 5pc. Both high voltage coil and the low voltage coil can be casted under vacuum pressure, which generates encapsulation of resin insulation with characteristics of flame retardant, explosion-proof and environment protection.

 

2. Raw materials of winding coil such as glass fiber have self extinguishing property, which will not produce arc when short circuit. The resin will not produce harmful gases at high temperature.

 

3. High mechanical strength: the resin with filler produces small difference of expansion coefficient in the casting body , small curing shrinkage rate , small internal stress, and high hardness of the solidified object . In the epoxy resin coating on the inner and outer surfaces of the high and low pressure coils, there are preformed reinforced materials, which have similar dense structure as the reinforced concrete, so mechanical strength of the casting body of this technique is greater than pure epoxy resin, and can withstand electrodynamic action under sudden short-circuit meanwhile without damage .

 

4. Low loss and energy-saving: The adoption of isotropic soft magnetic material generates low magnetization power, high electrical resistivity and low eddy current consumption.
