Energy-saving transformer development policy support

Energy-saving transformers have very prominent advantages in terms of technical performance. China is currently vigorously promoting the popularization stage, but it is not optimistic about market acceptance.

Power transformers are the key electrical equipment for power transmission. Transformer losses account for 30% to 40% of the power grid losses, while all transformers in China account for more than 3% of the national power generation. Therefore, the state has been focusing on energy saving and consumption reduction of transformers and has been vigorously promoting energy conservation and emission reduction.

As early as August 21, 2012, the State Council issued a detailed draft of the “12th Five-Year Plan for Energy Conservation and Emission Reduction”, which clarified the specific goals and investment plans for energy conservation and emission reduction during the “Twelfth Five-Year Plan” period, and called for “Twelve Five Years”. Reduce power transformer losses during the period, in which the no-load loss is reduced by 10% to 13% and the load loss is reduced by 17% to 19%.

On November 6, 2012, the Ministry of Finance, the National Development and Reform Commission, and the Ministry of Industry and Information Technology issued Cai Jianjian [2012] No. 854 to issue the Implementation Rules for the Promotion of Energy-Saving Products Huimin Engineering High-Efficiency Energy-Saving Distribution Transformers. The “Implementation Rules” divides the scope and conditions of promotion products, promotion of enterprise conditions, promotion deadlines, promotion and subsidy standards, promotion qualification applications, subsidy fund applications and disbursement, and penalties. The promotion product is a three-phase 10 kV application pressure level. Non-excitation regulator, energy efficiency grade 2 and above, rated capacity of 30 kVA to 1600 kVA oil-immersed type and rated capacity of 30 kVA to 2500 kVA dry type transformer.

In fact, the transformer energy efficiency standard is one of the focuses of power standardization work. In 2005, the power industry introduced a guideline for the economic evaluation of industry-standard distribution transformer energy efficiency technologies, which played a positive role in promoting the replacement of old transformers and lowering of energy efficiency. Fortunately, the current energy efficiency standard for 10-kilovolt three-phase distribution transformers has been submitted for approval; the guidelines for the economic evaluation of energy-saving technologies for distribution transformers have been implemented since July 1 this year; the design guidelines for transformers' environmental awareness since June 1 this year. Implementation.
