The Future Of Dry-type Transformers

With the promotion and application of Dry Type Transformer, its manufacturing technology has also made great progress. It can be predicted that the future dry-type transformers will be further developed in the following aspects:
⑴ Energy saving and low noise: With the introduction of new low-consumption silicon steel sheets, foil winding structures, stepped core joints, environmental protection requirements, in-depth noise research, and computer optimization design and other new materials, new processes, and new technologies, the future dry-type transformers will be more energy-saving and quieter.
⑵ High reliability: Improving product quality and reliability will be people's unremitting pursuit.
⑶ Environmental protection characteristics certification: Based on the European standard HD464, the research and certification of the weather resistance (C0, C1, C2), environmental resistance (E0, E1, E2) and fire resistance (F0, F1, F2) characteristics of dry-type transformers are carried out.
⑷ Large capacity: From 50~2500kVA distribution transformers to 10000~20000kVA/35kV power transformers. With the continuous increase of urban power load, urban network regional substations are getting deeper and deeper into urban central areas, residential areas, large factories and mines and other load centers. 35kV large-capacity community center power supply transformers will be widely used.
⑸ Multifunctional combination: From a single transformer to a multifunctional combined transformer with air cooling, protective housing, temperature computer interface, zero-sequence transformer, power metering, enclosed busbar and side outlet. It can be predicted that the distribution transformers in the 21st century will be resin-insulated dry transformers with superior performance, low noise and energy saving.
