energy efficiency improvement plan for distribution transformers

(year)

in order to implement the energy conservation law of the people's Republic of China and the implementation plan of major energy-saving technology and equipment industrialization project (fghz [2014] No. 2423), accelerate the development, promotion and application of efficient distribution transformers, comprehensively improve the energy efficiency level of distribution transformers and promote the upgrading of industrial structure of distribution transformers, the Ministry of industry and information technology AQSIQ and the national development and Reform Commission decided to organize the implementation of the national energy efficiency improvement plan for distribution transformers

I. necessity of implementing the energy efficiency improvement plan of distribution transformer

distribution transformer refers to the power transformer with operating voltage grade of kV and capacity of 6300 KVA and below, which directly supplies power to end users. It is widely used in end energy consumption fields such as industry, agriculture and urban communities. By the end of 2013, the total number of distribution transformers in operation in China was about 15.3 million, with a total capacity of about 4.8 billion kVA. Among them, the number of distribution transformers operated and managed by the power company is about 8.6 million, and that operated and managed by other enterprises is about 6.7 million

according to statistics, the loss of power transmission and distribution in China accounts for about 6.6% of the national power generation, of which the loss of distribution transformer accounts for%. Based on the national power generation of 5.32 trillion kwh in 2013, the power loss of distribution transformers in China is about 170 billion kwh, which is equivalent to 1.7 times of the annual power generation of the Three Gorges power station in 2013 (about 100 billion KWH). The power loss is very serious

as an important measure of energy conservation and emission reduction, many countries in the world have issued policies to improve the energy efficiency of distribution transformers. The United States launched the energy efficiency star transformer program as early as 1998, the European Union implemented the distribution transformer promotion partnership program in 2005, and Japan began to implement the transformer energy efficiency leader program in 2006

in recent years, China has also issued a number of policies to promote the application and industrial development of high-efficiency distribution transformers. In 2012, the State Council issued the 12th Five Year Plan for energy conservation and emission reduction, which clearly requires to reduce the loss of power transformers during the 12th Five Year Plan period, including no-load loss and load loss. In 2013, AQSIQ and the National Standards Commission jointly issued the national standard limited values and energy efficiency grades of three-phase distribution transformers (GB), which put forward higher requirements for the energy efficiency indicators of distribution transformers. Driven by these policies, China's distribution transformer industry has developed to a certain extent, and the output of high-efficiency distribution transformers (distribution transformers with energy efficiency of grade 2 and above specified in GB) has increased, but the overall energy efficiency level is still low. Up to now, the proportion of high-efficiency distribution transformers in the operation of distribution transformers in China is less than 8.5%, and the proportion of high-efficiency distribution transformers in the new volume is only 12%. The industrial development is relatively backward, and the energy-saving potential is huge

by formulating and implementing the energy efficiency improvement plan of distribution transformer, accelerating the popularization and application of high-efficiency distribution transformer and comprehensively improving the operation energy efficiency level of distribution transformer in China, it is of great significance to reduce the power loss of distribution transformer, promote the development of distribution transformer industry and promote industrial energy conservation and consumption reduction
