In the current development situation in my country, dry-type transformers account for an average of about 15%-20% in large and medium-sized cities, and about 50% in cities such as Beijing, Shanghai, Guangzhou, and Shenzhen. The application of dry-type transformers in the power grid is relatively small. Therefore, as a whole, dry-type transformers account for between 10-15% of transformer applications.
Although my country's market share is relatively low, with its own excellent application conditions and performance, the proportion of dry-type transformers in the total output of transformers will increase to a certain extent. It is estimated that by 2020, my country's dry-transformation market share will reach about 50%, which is equivalent to the current proportion of developed countries. Therefore, my country's dry-transformation market still has a long way to go.
my country's dry transformation technology has reached the world's advanced level
According to the "2013-2017 China Dry-Type Transformer Industry Market Demand Forecast and Investment Strategic Planning Analysis Report" of the Prospective Industry Research Institute, there are four types of dry-type transformers: epoxy resin casting, filler casting, wrapping, and immersion. At present, open-ventilated H-class dry-type transformers are widely used in Europe and the United States. They are a new type of H-class dry transformer developed after absorbing the characteristics of the wrap-around structure on the basis of the impregnated type and using Nomex paper. Not yet promoted.
At present, the domestic dry-type distribution transformers with the largest short-circuit test capacity are 2500kVA, 10/0.4kV; the dry-type power transformers with the largest short-circuit test capacity are 16000kVA, 35/10kV.
In 2012, the output of dry-type transformers in my country was 186,071,900 kVA, which is one of the countries with the largest production and sales of dry-type transformers in the world. Dry-type transformers are now widely used in almost all electrical applications such as power stations, factories, and hospitals. With the promotion and application of SC(B)9 series with low noise (distribution transformer noise below 2500kVA has been controlled within 50dB) and energy saving (no-load loss reduced by 25%), the performance indicators and manufacturing of dry-type transformers in China The technology has reached the world's advanced level.
Although the development of dry-type transformers in our country is still very long, under the guidance and development of policies and technologies, dry-type transformers will surely expand the market and gradually have a place in the international market.
