Policy support for the development of energy-saving transformers and analysis of market dynamics

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

Power transformer is the key electrical equipment for power transmission, transformer loss accounts for 30% ~ 40% of the power grid loss, and all transformers in China account for more than 3% of the country's power generation. Therefore, the state has been focusing on energy conservation and consumption reduction of transformers, and vigorously promoting energy conservation and emission reduction.

As early as August 21, 2012, the State Council issued a detailed draft of the "Twelfth 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 required the "Twelfth Five-Year Plan" period to reduce the loss of power transformers, including 10% ~ 13% of no-load loss and 17% ~ 19% of load loss.

On November 6, 2012, the Ministry of Finance, the National Development and Reform Commission, and the Ministry of Industry and Information Technology issued the "Implementation Rules for the Promotion of High-efficiency and Energy-saving Distribution Transformers for Energy-saving Products Benefiting the People" with Cai Jian [2012] No. 854. The "implementation rules" are divided into the scope and conditions of the promotion of products, the conditions of the promotion of enterprises, the promotion period, the promotion of subsidy standards, the application for promotion qualifications, the application and allocation of subsidy funds, and penalties 7 parts, and the promotion products are three-phase 10 thousand volt voltage level, non-excitation voltage regulation, energy efficiency level 2 and above, rated capacity of 30 thousand volt amperes ~ 1600 kVA oil-immersed and rated capacity of 30 thousand volt amperes ~ 2500 kVA dry-type transformers.

In fact, transformer energy efficiency standards are one of the key points of power standardization. In 2005, the power industry issued the industry standard distribution transformer energy efficiency technical and economic evaluation guidelines, which played a positive role in promoting the replacement of old transformers and the reduction of energy efficiency. Fortunately, the current energy efficiency standard for 10 thousand volt three-phase distribution transformers has been submitted for approval; The guidelines for the technical and economic evaluation of energy efficiency of distribution transformers were implemented from July 1 last year; The guidelines for environmentally conscious design of transformers have been implemented since June 1 last year.
