Open triangular three-dimensional coil core will become a new favorite of high-efficiency distribution transformer
When you or your company's boss are still struggling with the energy efficiency standard of the upper triangle three-dimensional coil transformer or the upper amorphous alloy transformer project, the open triangle three-dimensional coil transformer has passed the technical certification of the State Grid, and the breakthrough in the manufacture of new oriented silicon steel materials in China and the revolutionary innovative technology in the processing of the open triangle three-dimensional coil core are on the way. At the forefront of the world. These new products and technologies will certainly play an important role in the international competition of China's power industry and transformer industry. New technologies and technologies will promote the rapid development of China's transformer industry and play an important role in energy saving and consumption reduction.
Distribution transformer energy efficiency promotion plan has been issued and implemented. How to speed up the development and application of high-efficiency and energy-saving distribution transformers has become the focus of attention of the entire transformer industry. Recently, we have seen a large number of transformer enterprises and even some listed companies report and criticize the quality of transformers because they have been listed as poor suppliers by the State Grid, including in recent years, flaunting performance surpassing. The amorphous alloy transformers of all kinds of silicon steel transformers are not immune to the strict control of transformer standards in the national power grid. The quality problems caused by the defects of amorphous tape in terms of noise, brittleness, core fragments, surface smoothness, sudden short circuit and short-circuit resistance appear explosively, which leads to the re-examination of the end-users and departments that initially vigorously promoted amorphous alloy transformers. The misunderstanding of amorphous alloy transformer which was exaggerated in the past and brought about by amorphous alloy transformer's awareness and cost performance ratio has now become a negative impact. As another key raw material for transformer manufacturing, oriented silicon steel has seen breakthroughs in technology of domestic high quality oriented silicon steel, especially Baosteel, and some brands have reached the international advanced level. Some silicon steel processing equipment, core manufacturing enterprises and transformer manufacturing enterprises are pushing the new technology of silicon steel core processing for transformer products to the market, leading the world. At the Symposium on the Development of New Technologies (Products) for Transformer Unit Components and Materials held in Beijing in June this year, an open triangular three-dimensional winding core transformer (which we have the right to name first) attracted everyone's attention. The product has passed various reviews and has been unanimously praised and recognized by experts. This new product and technology will surely promote China's electric power industry and change. Voltage transformer industry plays an important role in international competition. New technology and new technology will promote the rapid development of China's transformer industry and play an important role in energy saving and consumption reduction. So, what is an open triangular three-dimensional core winding transformer? What advantages does it have in energy saving and production technology? Please follow me to uncover its mystery.
Open triangular three-dimensional coiled core transformer is based on closed three-dimensional coiled core to optimize and improve the structure of coiled core. The structure of the transformer perfectly integrates the traditional laminated core transformer and closed three-dimensional coiled core transformer. Compared with traditional laminated core transformer, the loss is lower, the cost is more advantageous, and the production process is simpler than closed three-dimensional coiled core transformer. The requirement of equipment is lower, which can easily meet the loss standard of S13 transformer grade 1 energy efficiency. It fully conforms to the national general idea of energy saving, green and environmental protection. Open triangular three-dimensional coil core transformer is an energy-saving transformer. It creatively innovates the traditional processing technology of silicon steel, integrates the shearing process into one, and reserves for the assembly of transformer coils. Convenient space makes the product performance more optimized. It can advance the production line circle and assemble quickly. The three independent geometric cores are actually composed of six groups of folding cores. Because the processing technology produces less stress on silicon steel, the core performance is better.
Folding R-shaped, elliptical, polygon and three-dimensional triangular cores are usually installed vertically.
Open triangular three-dimensional coiled core transformer has remarkable power saving effect, greatly reduced noise, stronger heat dissipation and overload capacity, compact structure and small volume, etc. It is especially remarkable for dry distribution transformers.
Open triangular three-dimensional coiled core transformer is the first one both at home and abroad. After nearly ten years of research and development, domestic enterprises have obtained nearly 30 national patents. This product solves a large number of technological problems in the production of traditional coiled core transformer. It combines traditional stacked core transformer with closed three-dimensional coiled core transformer, and has simple process and loss. It has the characteristics of low consumption, low cost, low noise, good electrical performance, simple repair and maintenance. Its technical parameters all meet the requirements of national standards and national energy-saving products. It has met the needs of mass production and has a very high application value.
However, such a good technology, although has passed the national technical certification, because its special processing technology has not yet determined a model standard, such as "three-dimensional coil core transformer" in its model letter RL, such as S13-MRL-100/10, SCB11-RL-1000/10, where R means coil core, L means three-dimensional structure. Although the open triangular three-dimensional coil core has the appearance of coil core, its core technology is not coiled, but through folding and shearing to obtain stereotyping, so it is not appropriate to use core technology as product type to characterize it as coil core, so this aspect still depends on the experts of transformer industry to have a voice to name it. I believe that in the near future, the open triangular three-dimensional coil core transformer will have a resounding name and standard code number active in the transformer field in China and even in the world.
In 2013, the General Administration of Quality Supervision and Inspection and the State Standards Committee jointly issued the national standard "Energy Efficiency Limited Value and Energy Efficiency Grade of Three-phase Distribution Transformer", which puts forward higher requirements for the energy efficiency index of distribution transformer. In 2015, with the release and implementation of the Energy Efficiency Promotion Plan for Distribution Transformers (2015-2017) of the Ministry of Industry and Information Technology, the General Administration of Quality Supervision and Inspection and the National Development and Reform Commission, China's energy-saving transformers entered a new era of large-scale application. The plan proposes to improve the construction of high-efficiency distribution transformer matching system, develop high-efficiency distribution transformer manufacturing and application demonstration, and enhance high-efficiency distribution transformers. Voltage transformer industrialization ability, from raw materials, technology, energy-saving technology and other aspects to promote the promotion and application of energy-saving transformers. Promoted by these policies, the open triangular three-dimensional coiled core transformer will surely make great progress in the process of distribution transformer industry in China.
