Description

A kind of amorphous band 35kV wind-powered electricity generation combined transformer

Technical field

The utility model relates to a kind of amorphous band 35KV wind-powered electricity generation combined transformer, belongs to technical field of electricity.

Background technology

The amorphous alloy core transformer is to use new magnetic material---non-crystaline amorphous metal is made the transformer that iron core forms, it makes the no-load loss of appendiron core transformer (when referring to the transformer secondary output open circuit than silicon steel sheet, in the elementary power loss that records) descend about 80%, no-load current is (during the transformer secondary output open circuit, elementaryly still have certain electric current, this part electric current is called no-load current) descend approximately 85%, be the comparatively ideal distribution transformer of present energy-saving effect.

Amorphous alloy transformer be if can substitute the distribution transforming of new S9 series fully, as 10kV level distribution transformer annual requirement during by 5,000 ten thousand kVA calculating, so, just can economize on electricity more than 10,000,000,000 kWh in 1 year.Simultaneously, also can bring the good environmental benefit of building power plant less, lack, can alleviate direct pollution so widely, make it become genuine Green Product of new generation environment to the airborne release greenhouse gas.

So, can improve utilization ratio of wind energy to a great extent if amorphous alloy transformer is combined with transformer with wind energy turbine set.Because amorphous alloy strips was limited by Hitachi Metals in the past, Hitachi Metals is as the single sourcing of global amorphous alloy strips, is 2.2 ten thousand tons in the production capacity of United States plants, and after 30,000 tons of newly-built projects of Japanese native country were gone into operation, present aggregated capacity was about 5.2 ten thousand tons.Yet Hitachi Metals is in 2.2 ten thousand tons of production capacities of the U.S., and about 8000-10000 ton is exported to China, and all the other products are supplied to other countries such as India, the U.S. and Japan.30,000 tons of production capacities of new enlarging in Japanese native country, about 8000-10000 ton is supplied with India market, supplies with markets such as the Japan and the U.S. for 10,000 tons, and the quantity delivered of newly-increased China mostly is 10,000 tons most.Generally, after the production capacity that Hitachi Metals is 5.2 ten thousand tons discharges fully, ten thousand tons of the about 2.0-2.5 of amorphous alloy strips of supply Chinese market.According to 1 ton of amorphous band produce 315KVA 2-1.5 calculating of 500KVA transformer, the amorphous band that Hitachi Metals is supplied with China amounts to can produce ten thousand of the about 3-4 of amorphous transformer.At present, ten thousand of the annual newly-increased distribution transformer 50-60 of China, annual 350000 in the transformer that upgrades of distribution.If 10% distribution transformer is used non-crystalline material instead, China will be up to more than 6.9 ten thousand tons to the demand of amorphous alloy strips.Only rely on the supply of Hitachi Metals, will there be huge insufficiency of supply-demand in China's amorphous alloy strips.

But because the manufacturing process and the stability of homemade iron core are slightly inadequate, and also do not possess the ability of production 170,213mm width band, so can only lean on the band of import Hitachi, Ltd.
