With the dry-type transformers in our continuous innovation and to promote a large number of applications, the domestic design and manufacturing technology has reached world-class level, the dry-type transformers in the future is expected to be further developed.
1, energy saving and low noise
Our loss and noise studies and energy conservation and environmental protection transformer manufacturing, already has a relatively high level. However, energy-saving and environmental protection is the eternal subject of research and development by the transformer, there are many issues worthy of study. Low loss silicon steel, stairs Diego core seams, foil winding structure, the depth of the noise studies, environmental requirements, computer optimization design of new materials, new technology, and the introduction of new technology and its development, will allow future dry the transformer more energy efficient more quiet.
2, high reliability
China has now produced tens of thousands of dry-type transformers, running in all fields, the key projects, major projects, product reliability requirements is self-evident. Electromagnetic field theory and its calculation, the casting process, hot temperature, Bureau put the mechanism of quality assurance system, reliability engineering and other aspects of a lot of basic research, actively reliability certification, and further improve the reliability of dry-type transformers will be The relentless pursuit of the people, but also dry change the topic of long-term design manufacturer.
3, the environmental characteristics of certification
In recent years, there are a few dry change enterprises through the ISO14000 environmental certification. IEC and European standards HD464, carry out dry-type transformers withstand thermal shock resistance, and the ability to adapt to the environment, fire resistance testing and certification. Epoxy resin casting dry-type transformers (CRDT) or Varnish Impregnated Dry Type Transformer (OVDT) in the research, development, and practice, have a lot of work to be done.
4, large capacity
Distribution transformer capacity is usually below 2,500 kVA. Currently, R & D and production of dry-type transformers as the main. With the city electricity load increasing, the city network of regional substations deeper and deeper into the urban centers, residential areas, large and medium-sized factories, mines and other load centers, regional power supply 35kV high-capacity dry-type power transformers is widely available. At present, China has produced a the 35kV, 16,000 kVA and 20,000 kVA large capacity dry change (several MR switch OLTC) If the project requires it, you can also design and manufacture a variety of larger capacity range of dry-type transformers. 5, multi-functional combination and intelligent
Only with a single substation transformer with forced air cooling, protective housing, power metering, enclosed bus, a variety of low-voltage lateral outlet, multifunction computer interface development of modular transformers, to the introduction of of TTU intelligent terminal data processing, state control, status display function, so the transformer to become a multi-functional intelligent electrical equipment at any time in the best run state. With the continuous development of information technology, the transformer will further accelerate the development of intelligent process.
6, multi-field development
From the main distribution transformers, the excitation to the power plant, the plant with rail transit traction rectifier current electric furnace, nuclear power plants, marine, oil platforms with multi-purpose multi-field development.
7, multi-material, multi-species
Epoxy resin vacuum casting dry-type transformers occupy a dominant global market situation. The NomexH level insulation, amorphous alloys, such as new materials, new technology, many companies have done some product development, and get a lot of data and experience, and to do in-depth research and development in many fields. The new development of future materials science, manufacturing process will certainly provide new opportunities for transformer design and manufacturing technology development, a new era.
