Dry-type Transformer is an Equipment for power transformation.
Dry-type Transformer is a kind of power transformation equipment that does not use insulating oil. It dissipates heat through natural cooling or air cooling. It is mainly used in high-rise buildings, power stations, commercial centers and other places that need fire protection, explosion protection and moisture protection. Its core and winding are not insulated with oil immersion. The shell material includes stainless steel, cold plate or aluminum alloy, which has flame retardant, explosion-proof and maintenance-free characteristics.
Advantages of Dry-Type Transformer：
1. Low loss, good power saving effect, bringing economic benefits in operation.
2. Flame retardant, explosion-proof, pollution-free, maintenance-free, can be dispersedly installed in the load center, reducing investment cost and saving costs.
3. The partial discharge is less than 10PC, the coil does not absorb moisture, dust, high mechanical strength and good reliability.
4. Good short circuit resistance and lightning impact resistance.
5. The shell is made of three materials: stainless steel, cold plate and aluminum alloy. The types are divided into pull-out wind type and heat dissipation type. The inlet and outlet lines can be in and out from the top, in and out from the bottom, and in and out from the bottom.
6. The transformer can be equipped with temperature control and temperature display system according to user needs, and can be used in conjunction with the temperature control system.
Operating Conditions：
1. Altitude does not exceed 1,000 metres.
2. Ambient Temperature
Maximum temperature: +40°C
Maximum daily average temperature: +30°C
Maximum annual average temperature: +20°C
Minimum temperature: -30°C (for outdoor transformers)
Minimum temperature: -5°C (for indoor transformers)
3. Power supply voltage waveform
The power supply voltage waveform should be approximately sinusoidal.
4. Symmetry of multi-phase power supply voltage
The power supply voltage connected to the multi-phase Satons transformer should be approximately symmetrical.
