Overcapacity, hidden quality, scattered industries have become the industry can not be ignored throughout the transformer industry, the plight of how to break the dilemma has been a common reflection of the industry, the issue of national energy-saving emission reduction policies may be in difficult times Transformer industry to provide an exit.
China's "12th Five-Year Plan for Energy Saving and Emission Reduction" requires that power transformer losses should be reduced during the 12th Five-Year Plan, including 10% -13% reduction in no-load loss and 17% -19% reduction in load loss. At present, High-power distribution transformers have not met the development trend of the industry, facing the technical upgrading, upgrading needs, the future will gradually be energy saving, material saving, environmental protection, low noise transformer replaced.
From the perspective of the development of energy-saving transformer technology, China's transformers experienced several series of alternative processes such as S7, S8, S9, S10 and S11. At present, it seems that in the transformation of the national urban network and rural power grids, large quantities of S13 and SH15, the load loss is 50% ~ 80% lower than that of the S9 transformer.However, the S9 type products are still being used in large areas in many areas, and some S7 type products are still used even in remote areas.
On the one hand, in the promotion of energy-saving transformer products, the price is still the main factor that affects the popularization and promotion of energy-saving transformers because the selling price of products is higher than that of traditional transformers. The reason for the high prices caused by the high price of new materials. On the other hand, the current market situation of energy-saving distribution transformers is fragmented. Coupled with the low barriers to entry, the mixed enterprise, the lack of definition and standards, technological bottlenecks, high prices and inadequate subsidies, the promotion of energy-saving transformers in China is slow.
At present, the biggest problem plaguing the transformer manufacturing enterprises is the lack of a uniform definition of energy-saving transformers and standards, coupled with short running time, there are some controversy and users can not fully accept the doubt, such as amorphous alloy distribution transformers after the operation of functional stability Poor sex, short circuit resistance, noise and loss increase. In addition to the most critical technical aspects, testing standards and testing techniques lag behind product development, and there is a lack of product performance evaluation, rating system and tools that reflect different design levels and manufacturing processes.
Should be said that energy-saving transformer is the trend of the times, China is also improving energy-saving transformer standards to further standardize the industry market, in addition to energy efficiency standards and subsidies, but also in business models, technological breakthroughs, the use of new materials such as policy overweight , To promote large-scale application of energy-saving transformers.
