Core advantages
● Inherent safety design
By using an air/epoxy resin composite insulation system, the combustible medium of oil immersed transformers is fundamentally eliminated, and its fire resistance meets the IEC60076-11 standard, especially suitable for secondary power load requirements in densely populated areas.
● Environmental protection throughout the entire lifecycle
The design without mineral oil avoids the risk of soil pollution, and with the application of stepped laminated iron cores and amorphous alloy materials, the no-load loss is reduced by 15% compared to the national standard, and the operating noise meets the residential area limit requirements of GB/T 1094.10-2020.
● Digital operation and maintenance
Integrated PT100 temperature sensor and IoT communication interface, supporting intelligent start stop (± 2 ℃ accuracy) and remote warning of fans, with a typical maintenance cycle extended to over 5 years.
Key Technology Analysis
● Magnetic circuit system: 30ZH120 silicon steel sheet treated with laser irradiation reduces hysteresis loss by 20%;
● Winding process: High voltage coil vacuum pressure impregnation (VPI) treatment, low-voltage copper foil winding certified with F-class insulation;
● Thermal management plan: AN/AF dual-mode cooling system optimized through CFD fluid simulation, with overload capacity up to 1.5 times/2 hours;
● Mechanical protection: The IP23 protection level shell is matched with magnesium aluminum alloy heat dissipation ribs to achieve C4 level anti-corrosion performance.
Scenario based application
Covering scenarios such as urban rail transit (protection level IP54), commercial complexes (fire zone applications), and new energy power stations (35kV direct hanging systems), the capacity gradient configuration supports plug and play deployment, and the photovoltaic adaptation version can withstand 10% harmonic distortion rate.
