Policy helps the transformer market usher in spring

Amorphous alloy transformer leader Zhixin Electric announced on May 6 that the company had won the bid of the State Grid Corporation of China distribution equipment and the Jiangsu Electric Power Company’s new residential area for distribution and distribution materials, totaling approximately 1.11 billion yuan. According to industry analysts, at present, under the backdrop of the state's efforts to promote energy conservation and emission reduction, both State Grid and China Southern Power Grid have replaced energy-saving transformers as a major measure to reduce power grid losses, which has brought many market opportunities to energy-saving transformer manufacturers. Even for the entire energy-saving transformer market has a guiding and remodeling role.

An expert in the energy-saving potential of transformers National Transmission and Distribution Technology Network said that transformers are the key electrical equipment for power transmission. Because of the large number of transformers, the power consumed by the transformer itself is also considerable. Relevant data show that, at present, all the transformers in China consume 3% to 10% of the electricity generated in the country. In the loss of distribution network, transformer losses account for 40% to 60%. The potential for energy saving is huge.

In accordance with the requirements of the “12th Five-year Plan for Energy Saving and Emission Reduction”, during the 12th Five-Year Plan period, the loss of power transformers will be reduced. The no-load loss will be reduced by 10%-13%, and the load loss will be reduced by 17%-19%. Therefore, the high-energy operation on the network is required. The replacement of energy-efficient products by consumption transformers has become an industry trend.

It is understood that energy-saving distribution transformers include amorphous alloy core transformers, capacity transformers, etc. Such as amorphous alloy transformer, is an energy-saving transformer developed in the 70s of last century. Due to the use of a new amorphous alloy of soft magnetic material, the performance of amorphous alloy transformers surpasses that of conventional silicon steel transformers. It is estimated that the amorphous alloy transformer will reduce the no-load loss by 80% compared with the traditional silicon steel transformer, and the no-load current will drop by about 85%. This is an ideal distribution transformer with good energy-saving effect, but it does not have the price and raw material supply. Advantage.

The market is still not fully activated. Industry sources have told reporters that the current energy distribution transformer market in China is scattered, coupled with low industry barriers, uneven business, lack of identification and standards, and inadequate technological innovation and other factors, leading to slow promotion of energy-saving transformers.

According to reports, China's transformers have undergone several series of alternative processes such as S7, S8, S9, S10, and S11. As early as the mid-1980s, the Chinese government made mandatory use of the S7 series of low-loss distribution transformers to eliminate the JB1300-73 and JB500-64 standard high-energy-consuming transformers that were operating on the grid at the time. Since 1998, the urban and rural power grids have been transformed throughout the country, and the S7 series of distribution transformers have been used instead of the S7 series. In recent years, S13 and S15 products have begun to be used in large quantities in the transformation of national urban networks and rural power grids, and their no-load losses have been reduced by 50%-80% compared with S9-type transformers.
