Xuzhou Pengcheng Electric Co., Ltd. dry-type transformer oil-immersed transformer development history

In the past ten years of development, China's power construction has developed rapidly with remarkable achievements. Among them, the installed capacity of power generation has grown at a high speed, the speed of power grid construction has soared, the adjustment of power supply structure has been continuously optimised, the level of technology and equipment has been greatly improved, energy saving, emission reduction and consumption reduction have been remarkable, and the construction of electric power has achieved leapfrog development. This has provided a strong impetus for the stable and rapid development of China's economy and society, and played an important role in supporting and safeguarding the improvement of people's lives.

National Bureau of Statistics data show that from 2007 to 2011, the sales scale of power transformer manufacturing industry has been expanding, sales revenue grew at a rate of more than 13% per year, and the sales revenue reached 178.436 billion yuan in 2011, up 16.53% year-on-year; total profit of 10.214 billion yuan was realised, a year-on-year decrease of 5.43%.

Overall, in 2011, China's power transformer manufacturing industry developed steadily, but profitability declined. For the consideration of the global economic environment, China may increase the proportion of renewable energy in the future. The State Grid and the Southern Grid are researching light DC, which are new trends that will bring new areas of development for the transformer industry.

And the development and use of power transformers in the market more and more widely, in terms of technology and quality of some of these well-known enterprises also stand out for example, an open investment group for many years the company has been committed to the development of the national electrical industry, with many research institutes, universities and international industry giants to establish close co-operation, set up the ‘Shanghai Yikai Electrical Appliance Scientific Research Institute Shanghai Yikai Electric Scientific Research Institute’, specialising in the research and development, production of power transmission and distribution control equipment, high and low voltage electrical components, intelligent electrical products, has developed a variety of high and low voltage electrical components, such as “Intelligent PLC control panel” and “Intelligent complete set of switch total control”, Low-voltage electrical components; and Shenyang Transformer Research Institute, research and development, production of high and low voltage transformer products, has developed the S (B) H15-M, S (B) H16-M amorphous alloy rolled iron core power transformers, SC9, SCB9, SC10, SCB10 series of resin-insulated dry-type transformers, SG10 type H-type insulated dry-type transformers, SGB11-R rolled iron core H-type non-encapsulated coil dry-type power transformers, and SGB11-R rolled iron core dry-type power transformers, and SGB11-R rolled iron core H-type non-encapsulated coil dry-type power transformers. Class non-encapsulated coil dry-type power transformers, 10kV class S9, S11 series oil-immersed power transformers, 35kV class S9-□-□ series oil-immersed power transformers and other series of products and at the same time the development and production of the transformer production of foil-type winding machine, amorphous alloy shear, high and low voltage winding machine and other special machinery and equipment; and the United States General Motors (GE) to create the Asia-Pacific region's largest and most professional marine switchgear and low voltage winding machine; and the General Motors (GE), to create the most professional marine switchgear and low voltage winding machine. In conjunction with General Electric (GE) to build the largest and most professional marine switchgear and low-voltage electrical equipment in the Asia-Pacific region, the company has developed GEA plus2.0, Modula plus, Modula 630k, marine transformers, marine box-type substations, marine electrical automation equipment, tunnel distribution cabinets and other series of products.

Development prospect

1, medium-frequency transformer production, low prices, and export-oriented, exports drive its rapid development. At present, China's electronic system within the enterprise medium frequency transformer industry average price of 0.626 yuan / only, but most of the average ex-factory price of 0.20 ~ 0.30 yuan / only between the high one in 1 yuan / only about.

2, power transformer market demand is strong. Power transformer is a labour-intensive products, and customized production to the user, in recent years the domestic and international market demand is strong, and has become a fast-growing popular products. And India will grow 25%. Communications, computers, consumer electronics is its three main markets, including communications demand growth will play a big role in driving the annual demand for power transformers is now more than ten billion U.S. dollars globally, and to the surface mounting, high power and high-voltage aspects of development.

3, amorphous alloy transformer if you can completely replace the new S9 series of distribution transformers, such as 10kV class distribution transformer annual demand for 50 million kVA calculation, then, a year will be able to save 10 billion kW?h or more. At the same time, can also bring less power plants to build a good environmental benefits, less greenhouse gas emissions into the atmosphere, which will greatly reduce the direct pollution of the environment, making it a new generation of green products worthy of the name. In short, the country in the urban and rural power network system development and transformation, if a large number of three-phase amorphous iron core distribution transformer products, it will ultimately obtain energy saving and environmental protection benefits.
