400mva 220 (230) Kv Oil-Immersed Three Phase Double Winding Power Transformer with off-Load Tap Changer

Product overview

The transformer can transform the voltage of the power network into the voltage needed by the system or load to realize the transmission and distribution of electric energy. Amorphous alloy transformer, as a kind of new energy saving technology power distribution equipment, energy saving effect mainly comes from the adoption of a new type of ferrous amorphous alloy material with excellent soft magnetic properties. Sbh15-m series products comply with the national standard Gb1094power transformer and GB/T25446-2010 oil-immersed amorphous alloy core distribution transformer technical parameters and requirements

Product features

1. Amorphous alloy is a new type of strip. Amorphous alloy material does not have crystal structure

2. A type of energy-saving transformer can be produced by using this material as core, the no-load loss is more than 75% lower than the current S11 distribution transformer. The iron core is a rolled iron core structure with three-phase five        

   column type and rectangular section

3. The coil is rectangular, and the high voltage is wound with enamelled acetal wire, while the low voltage is wound with flat wire or copper foil, to increase the ability of the transformer to withstand short circuit

4. The transformer connection group adopts DYN11 to avoid the influence of high-order harmonics, strong resistance to unbalanced load, and significantly improve the power supply quality.

5. The transformer adopts vacuum oil injection, which can completely eliminate the air bubbles in the coil and ensure the stable nsulation performance

6. The oil storage tank is cancelled, and the oil pipe is replaced by the corrugated or plate radiator as the cooling element. The oil tank has an air cushion, Which can be compressed with the volume expansion of the transformer oi
