Transformer energy efficiency level.

make a task request

A few days ago, Guo Zhenyan, vice president of China Electrical Equipment Industry Association and director of Beijing Institute of Electrical Technology and Economics of Machinery Industry, introduced the main tasks and measures for implementing the "Plan" in detail.

Guo Zhenyan said that the "Plan" aims to increase the application ratio of high-efficiency distribution transformers on the user side. High energy consumption distribution transformers of S9 and below models with operating time of more than 15 years.

Make full use of the financial subsidy policy to promote the promotion of high-efficiency distribution transformers. Continue to implement the policy of promoting financial subsidy for high-efficiency distribution transformers of the energy-saving and benefiting project. According to the already released GB20052-2013 "Three-phase Distribution Transformer Energy Efficiency Limits and Energy Efficiency Grades" and other energy efficiency standards for distribution transformers to be revised and formulated, expand the promotion scope of high-efficiency distribution transformers and increase financial subsidies for high-efficiency distribution transformers . Encourage all local government departments to introduce differentiated energy-saving products Huimin project distribution transformer promotion subsidy policy, and further accelerate the promotion of the use of high-efficiency distribution transformers.

Encourage distribution transformer enterprises to achieve technological innovation. Implement a series of standards related to distribution transformers, and prohibit distribution transformer companies from producing high-energy-consuming distribution transformers with energy efficiency levels lower than three. Introduce the distribution transformer technology innovation incentive policy, give policy incentives and market priority promotion and use encouragement to high-performance distribution transformers that master the core technology intellectual property rights, promote manufacturing enterprises to enhance technological innovation and research and development capabilities, strengthen the improvement of enterprise process manufacturing level, cultivate A group of large-scale backbone enterprises with large scale, good benefits and high market share.

Develop a recommended catalog of high-efficiency distribution transformers. Set the access conditions for the recommended catalog of high-efficiency distribution transformer products, and actively guide users to choose reliable and efficient distribution transformers through the recommended catalog to achieve two-way incentives for users and manufacturers. At the same time, strengthen inspection and testing, certification evaluation, quality supervision and energy efficiency review, and ensure that all new high-efficiency distribution transformer products meet the energy efficiency standards of high-efficiency distribution transformers through the management of energy efficiency grades of distribution transformers.

Gradually improve the elimination mechanism. First, in accordance with the new energy efficiency standards for distribution transformers, formulate the "Retirement Catalog for High Energy-consuming and Backward Electromechanical Equipment (Products)" (the fourth batch), and replace the S10, SC(B)9 and S9 series with high no-load loss and large load loss. Distribution transformers are included in the phase-out list. Second, according to the "Energy Conservation Law of the People's Republic of China" and the "Twelfth Five-Year Plan" Comprehensive Work Plan for Energy Conservation and Emission Reduction by the State Council, the elimination of high-energy-consuming distribution transformers is an important way to save energy and reduce consumption. Users and other relevant units should formulate a work plan that suits their actual situation as soon as possible and report to the Ministry of Industry and Information Technology for recordation and organize their implementation. The third is to combine the elimination of high-energy-consuming distribution transformers with the goals and tasks of the global CDM (Clean Development Plan) project, and give priority to launching assistance plans in the power, steel, manufacturing, chemical, metallurgical, building materials and other industries to promote independent installation by enterprises. High-efficiency distribution transformers replace existing high-energy-consuming distribution transformers to achieve energy conservation and emission reduction.

Reasonably formulate a roadmap for elimination. Make full use of administrative, market, economic and other means to promote the gradual withdrawal of backward and inefficient distribution transformers from the application market. By the end of 2014, complete the list of S7 series and below and all kinds of old products that have been in operation for more than 20 years in the Ministry of Industry and Information Technology's "High-energy-consuming and backward electromechanical equipment (products) elimination catalog" (the first batch). The task of eliminating distribution transformers; before 2015, complete the elimination of high-energy-consuming S7 series and SC(B)8 series distribution transformers; before 2016, complete the elimination of S9 series distribution transformers that have been connected to the grid for 15 years or more Task. Encourage enterprises to take the initiative to eliminate high-energy-consuming distribution transformers with a running time of more than 10 years or more.

Establish a recycling mechanism for obsolete transformers. Formulate the classification standards, scrap standards, recycling and dismantling technical specifications for the elimination of distribution transformers; support the establishment of large-scale and standardized recycling bases for waste distribution transformers in various provinces and cities. Encourage a group of enterprises specializing in the recycling, dismantling and reuse of transformers, and promote the fixed-point recycling compensation mechanism for the elimination of waste distribution transformers.

Improve the supervision system for the recycling of waste transformer materials. Strictly control the rational reuse of waste materials eliminated from old transformers to ensure that they no longer directly enter the transformer manufacturing process. Reliable silicon steel sheets are used on small reactor cores without energy consumption requirements; insulating oil is recycled and used in other industrial fields after reprocessing; relatively precious metal raw materials such as magnet wires and foils are handed over to electromagnetic It can be reasonably offset by the processing and manufacturing plants of wire or foil, or directly applied to other industrial fields that require copper.

Establish a management mechanism for decreasing energy consumption as soon as possible

According to Guo Zhenyan, an energy consumption reduction management mechanism should be established as soon as possible to promote the energy efficiency improvement of distribution transformers.

Guo Zhenyan said that the proposal of the "Plan" is to adopt different energy consumption reduction management methods for power grid companies and industrial enterprises according to the different users of distribution transformers, and establish a long-term mechanism for energy efficiency improvement. Power grid enterprises use the comprehensive line loss of the distribution network that decreases year by year as the main assessment index; industrial users take the power consumption per unit product as the main assessment index. When setting the energy consumption reduction target, according to the power grid company's distribution network loss index and the average power consumption level of various industries and enterprises in the previous year, the next year's reduction target will be implemented according to the overall target yearly to ensure the feasibility of the reduction target.

Its goals are: to solve the bottleneck problem affecting the production of high-efficiency distribution transformers, promote the upgrading of the distribution transformer industry, and enhance the industrialization capacity of high-efficiency distribution transformers.
