Intelligent on-load transformers add color to green manufacturing

The intelligent on-load capacity-adjusting transformer is a new type of transformer that integrates energy-saving and environmental protection intelligence. The new type of transformer is in line with the industrial green development plan of the Ministry of Industry and Information Technology (20162020). Green manufacturing industry requires comprehensive utilization of energy-saving and environmental protection equipment resources. As green manufacturing is expected to become a new engine for economic growth, intelligent on-load capacity transformers will also usher in an optimistic market prospect.

    The main features of intelligent on-load capacity-adjusting transformers in terms of energy-saving industrial intelligence and market potential are as follows:

    1. Automatic adjustment according to the size of the capacity, with the advantages of energy saving and emission reduction

    Statistics show that the total power loss of transformers in China is more than 300 billion kWh. It is equivalent to the sum of electricity consumption in three medium-sized provinces, and the power loss of a large number of transformers comes from seasonal changes in rural power distribution, causing serious overload of transformers and large horse-drawn car problems. .

    The intelligent on-load capacity-adjusting transformer can be automatically adjusted according to the capacity, which solves the common problems of overloading and large-scale horse-drawn vehicles. The energy-saving and emission-reducing benefits are taken as an example of the case of Guangdong Power Grid Corporation Qingyuan Qingxin Power Supply Bureau. In 2014, the district's rural electricity consumption in the Qingxin District was about 187.75 million kWh. If the transformers in the Qingxin District were all replaced with intelligent load-carrying transformers, it would save about 18.875 million kWh per 1 kWh of energy saving, saving standard coal. 0.35 kg, carbon dioxide emission reduction of about 0.71 kg, the entire Qingxin District can save about 6,600 tons of standard coal and reduce carbon dioxide emissions by 13,400 tons.

    2. The market has potential

    Although the intelligent load-carrying transformer has a small market share, its market potential is very different from that of many energy-saving products. The intelligent on-load transformer will be welcomed by the market.

There are two problems in rural electricity use. One is that the electricity load varies greatly in different seasons. The second is the surge in electricity consumption during the Spring Festival. For example, during the holidays, especially during the Spring Festival, the number of returnees in rural areas has suddenly increased, and electric heaters such as induction cookers have been installed. Concentrated use, often the highest load exceeds the normal four or five times of the same period of the traditional solution is to replace the larger capacity transformer before the Spring Festival, but after the Spring Festival, the load rate is greatly reduced, a large amount of electrical energy can only be lost in this In this case, replacing the small-capacity transformer again requires a lot of manpower and material resources and increases the safety risk of operation and maintenance. The intelligent on-load capacity-adjusting transformer can solve the two problems in the rural area. Therefore, the local residents of the power sector have demand. The application range of intelligent on-load capacity-adjusting transformers is not only in rural areas, but also in many industrial and mining enterprises, urban residential areas and commercial areas have different power load differences.

    3. Less constraints

    Although many energy-saving products have good market prospects and energy-saving effects, they are difficult to develop rapidly due to factors such as the cost of patented materials, and smart load-carrying transformers do not have these constraints. The patents are domestic enterprises, and many domestic Enterprises can produce marketable products. The power grid company fully cooperates with the network experiment and application. Various technical specifications for intelligent on-load capacity transformers have been introduced one after another. China also has industrial accumulation in power electronics technology, and this product does not need other specials. material.

    4. Have a price comparison advantage

    Compared with ordinary S13 type transformers, the new intelligent load-carrying transformers increase the manufacturing cost by about 20,000 yuan (only the special reference price of a certain model), which is a new marketable product. This price is relatively moderate and reasonable, and users can share energy-saving benefits by saving electricity. Manufacturers can enjoy various national support and incentive policies. Grid companies can save a lot of transformer maintenance and modification costs, and can also reduce the installation of mother and child. The extra cost of the transformer, in addition to the technical part of the product is in the power electronic control system, compared with the traditional manufacturing industry, it has more space to reduce costs after large-scale production.

    5. Have international competitiveness

    On April 12, 2016, the Chinese Academy of Electric Power and other units entrusted the China Machinery Industry Federation to hold an evaluation committee for the research and development of engineering and application of scientific and technological achievements in the key technology series of equipment for load-carrying and regulating voltage distribution transformers in Beijing. The comprehensive performance indicators of the series of load-regulating and regulating distribution transformers have reached the international leading level.

    6. In line with the development direction of smart grid

    The Industrial Green Development Plan (20162020) emphasizes the combination of industry and intelligence, the integration of industry and Internet +, and China's power grid companies are also making efforts to build smart grids. Intelligent on-load capacity-regulating transformers have these characteristics and can be adapted to China. In summary, the products of intelligent and smart grid development, China's green manufacturing industry is welcoming the historical opportunity of a hundred flowers, intelligent load-carrying transformers will become a beautiful spring flower because of the various conditions mentioned above. .
