China Electric successfully enters the polysilicon reduction furnace transformer market

The market needs performance support. For China Electric, which has not previously achieved the market performance of polysilicon reduction furnace transformers, it is certainly difficult to open and occupy this market. However, China Electric Electric used its strength to speak and rely on quality to break through. Recently, 2 sets of polysilicon reducing furnace transformers produced by the epoxy dry-drying division of China Diandian Electric (Jiangsu) Co., Ltd. succeeded in carrying loads at Jiangxi Jingde Semiconductor New Material Co., Ltd. The operation became a sign of China Electric's successful "invasion" into this field.

The energy crisis has exacerbated people's hunger for new energy. As a clean and renewable energy source, solar energy has received more and more attention from people around the world. It has objectively promoted the rapid development of the solar photovoltaic power generation industry, and at the same time, the raw materials in the industry. - The production of polysilicon also produced a great driving effect. The polysilicon production lines that have been launched have also increased the market demand for polysilicon reduction furnace transformers, and Bo Guixiang, deputy general manager of the epoxy dry-drying division of China Electric Power (Jiangsu) Co., Ltd., told reporters that there will be polysilicon reduction furnace transformers around 2007. The bulk demand of the market has experienced the global financial crisis in 2008, and the photovoltaic industry has entered a low point all of a sudden. However, by the second half of 2010, the polysilicon industry became hot and polysilicon production-related industries were started, such as polysilicon reduction furnaces. Transformers, hydrogenation furnace transformers, etc.

To do things early, in the early days, some transformer manufacturers entered the polysilicon reduction furnace transformer market in advance, but there are not many domestic manufacturers that have produced such transformers until now. The reason is that due to the special requirements of such transformers, customers are very concerned with the use of transformers. Baigui Xiang said that polysilicon reduction furnace transformer in the early stage of operation due to the characteristics of polysilicon reduction requires high voltage, low current, to the lower end of the restoration requires low voltage, high current; in the polysilicon reduction process, the reduction furnace temperature inside Keep at about 1100 degrees to ensure the growth requirements of the silicon rod, all this must be achieved by the power conditioning cabinet connected to the reduction furnace. The power supply to the power conditioning cabinet is the transformer; and the silicon rod is very much in the process of reduction of polysilicon. Popping, broken rods, etc. may occur, and the rods are short-circuited to the transformer. Therefore, the ability of the transformer to withstand sudden short circuits is very high. For a transformer, a three-phase load is unbalanced. The situation is very demanding on the transformer. In case of failure, not only the growth of the silicon rod will be affected, but also there is a great danger. "To find customers to communicate, customers will ask, where used your products? This type of transformer, without performance, it is difficult to open up the market."

Difficulties are difficult, but it is undeniable that this is a big market. According to the survey, the number of reduction furnace transformers required by the polysilicon industry in 2011 reached 3,000, and with the development of the solar photovoltaic power generation industry, this market potential is increasing unabated. Do you not look hard at the opportunity to slip away? No, in 2010, China Electric Power Group decided to launch an "attack" in this area and handed over this task to the Epoxy Drying Division of the joint stock company.

Bai Guixiang said that after receiving this task, they did not immediately begin immersive research and development work, but set up a research and development team of polysilicon reduction furnace transformers mainly consisting of senior engineers, R & D team went to a number of polysilicon manufacturers to understand the polysilicon production process , Also to the well-known domestic power supply manufacturers to demodulate the work of the cabinet. “We have learned in detail what problems will occur in the production of polysilicon and how the power conditioning cabinet will operate. What will be the status of the imported polysilicon reduction furnace in actual operation...” After mastering these first-hand information, R&D The personnel are known, "The principles of transformers are the same, and they will never change. The difference is that their operating conditions are not the same as the loads they carry."

After more than a month of efforts, the Epoxy Drying Division came up with a preliminary design plan for polysilicon reduction furnace transformers, which not only fully considers the operating conditions of the transformers, but also affects the impact of the connected equipment such as power conditioning cabinets and reduction furnaces. And improve the design, to avoid other manufacturers in the actual operation of some unsatisfactory places, "such as imported reduction furnace transformer noise is relatively large, the temperature rise is relatively high, high loss and high energy consumption."

Finally, with many years of experience and strength in the production of transformers at Zhongdian Electric, after several communications, the Epoxy Drying Division at the end of last year managed to secure orders for two ZLSCB10-5000/10 polysilicon reduction furnace transformers from Jiangxi Jingxin Company. With the unremitting efforts of all employees in the Epoxy Drying Division, the finished product was delivered to the customer 15 days in advance. The two polysilicon reducing furnace transformers have been operating since May 20th without any quality problems. According to the report from Jiangxi Jingxin Company, compared with the transformers used in the reduction furnaces before, the products of the Epoxy Drying Division have low noise, energy saving, and low temperature rise, reaching the advanced level of the industry.

With these two transformers “heading the line,” the Epoxy Drying Division formally launched a clarion call for the polysilicon reduction furnace transformer market. Bai Xiangxiang also stated that the epoxy dry-energy division's "advancement" of the transformer industry dedicated to photovoltaics is precisely the strategy of implementing the group's "breakthrough development." "Now the conventional transformer market is extremely competitive and the country is in the 12th Five-Year Plan." The plan proposes to vigorously develop emerging industries. These emerging industries contain unlimited business opportunities. If we want to break through the development, we must seek new markets from these new industries, and we must first break through and seize the commanding heights."
