The future of dry-type transformers

With the promotion and application of dry-type transformers, their production and manufacturing technology has also made significant progress. It can be predicted that future dry-type transformers will further develop in the following areas:
⑴ Energy saving and low noise: With the introduction of new low consumption silicon steel sheets, foil winding structures, stepped iron core joints, environmental protection requirements, in-depth noise research, and the use of new materials, processes, and technologies such as computer optimization design, future dry-type transformers will be more energy-efficient and quieter.
⑵ High reliability: Improving product quality and reliability will be people's unremitting pursuit.
⑶ Environmental characteristic certification: Based on the European standard HD464, conduct research and certification on the weather resistance (C0, C1, C2), environmental resistance (E0, E1, E2), and fire resistance (F0, F1, F2) characteristics of dry-type transformers.
⑷ Large capacity: From dry-type transformers mainly used for 50-2500kVA distribution, to 10000-20000kVA/35kV power transformers, with the continuous increase of urban electricity load, urban power grid regional substations are becoming more and more deeply integrated into load centers such as urban centers, residential areas, and large factories and mines. 35kV large capacity community center power transformers will be widely used.
⑸ Multi functional combination: From a single transformer to a multifunctional combination transformer with air cooling, protective shell, temperature computer interface, zero sequence transformer, power metering, enclosed busbar and side outgoing line. It can be predicted that distribution transformers in the 21st century will belong to resin insulated dry-type transformers with superior performance, low noise, and energy saving.
