Amorphous alloy transformer performance requirements

Now widely used in the new S9-type distribution transformers, magnetic materials used in its core is usually cold-rolled silicon steel 30Z140 high permeability, high saturation flux density than the amorphous alloy, product design selected flux density usually between 1.65 ~ 1.75T. This is the amorphous alloy core distribution transformers than the new S9 type distribution transformers a major no-load loss is low. Table 1 is a three-phase amorphous alloy core distribution transformers with new S9-type distribution transformer load loss value comparison. Amorphous alloys and new S9-type distribution transformer load loss value is relatively foil winding machine

Amorphous alloy transformers effect

Three-phase amorphous alloy core distribution transformers, compared with the new S9-type distribution transformers, the annual electric energy savings are considerable.

To 800kVA, for example, △ P0 is 1.05kW; load loss values of the two types of distribution transformers are the same, then △ Pk = 0,, a product can be calculated to reduce annual energy consumption is:

△Ws=8760(1.05+0.62×0)=9198kW?h

By calculating the specifications of the product shows that the energy saving effect of three-phase amorphous alloy core distribution transformers series of unusual. Because the tank has designed, fully sealed structure, so that the oil inside the transformer and the outside air is not in contact, to prevent oxidation of the oil to extend the life of the product, users can save maintenance costs.

Prospects amorphous alloy transformer

If we can completely replace the amorphous alloy transformer S9 series of new distribution transformers, distribution transformers of 10kV time as the annual demand by 50 million kVA calculation, then, a year can be energy-saving 10 billion kW? H or more. At the same time, reduce the construction of the power plant can also bring good environmental benefits, fewer emissions of greenhouse gases into the atmosphere, it would greatly reduce direct pollution of the environment, making it truly a new generation of green products. In short, the national power grid system in urban and rural development and transformation, if a lot to promote the use of the three-phase amorphous core distribution transformers, which eventually will get benefits of energy saving and environmental protection in two ways.
