The development trend of dry-type transformers in China
Release time: 2017-05-09 Clicks: 1330 times
The continuous development and innovation of dry-type transformers in China and a large number of popularization and application, the domestic design and manufacturing technology has reached the world-class level, and future dry-type transformers are expected to further develop. 1. Multi-field development: mainly from distribution transformers, to multi-purpose and multi-field developments such as power plant excitation, plant use, rail transit traction rectification, high-current electric furnaces, nuclear power plants, marine applications, and oil production platforms. 2. Multi-material, multi-type epoxy resin vacuum casting <0> occupies the world's leading market situation. Many companies have done some product development for NomexH-class insulation, amorphous alloys and other new materials and processes, obtained a lot of data and experience, and will do in-depth research and development in many fields. And the new development of material science and manufacturing technology in the future will certainly provide new opportunities and open up a new era for the development of transformer design and manufacturing technology. 3. High reliability China has produced tens of thousands of dry-type transformers, which are used in various fields, key projects, and major projects. The requirements for product reliability are self-evident. Do a lot of basic research on electromagnetic field theory and its calculation, casting process, hot-spot temperature rise, partial discharge mechanism, quality assurance system, reliability engineering, etc., actively perform reliability certification, and further improve the reliability of dry-type transformers. It will be people The unremitting pursuit is also a long-term issue for dry change design manufacturers.
