Product Overview: The rail transit three-phase dry-type transformer is key for converter power supply. In rail's electrical ecosystem, it offers stable energy for train power and safety, backing rail transit's efficient and safe running. Specific Introduction: 1.High-Permeability Material Effect: High-perm. silicon steel sheets are significant in converter power supply. They guide magnetic flux well, cut excitation current, boost power factor, optimize energy quality, slash harmonic interference, ensure rail equipment's stable and efficient running, and adapt to complex and changeable work. 2.Heat Dissipation & Reliability Upgrade: Good heat dissipation design means low temperature rise. In rail's vibration, it still dissipates heat efficiently, shields insulation material performance. With flame-retardant and three-proof treatment, it toughens transformer reliability and durability, cuts maintenance times, and ensures long-term stable operation. 3.Low Magnetic Leakage: Low magnetic leakage design curbs interference to nearby equipment, enhancing system compatibility. It has three-proof and flame-retardant materials, works in rail's humidity, dust, and heat. The PT100 eases temperature monitoring and maintenance management, ensuring reliable operation. Operation Environment A) Altitude: Not exceeding 1000m, shall be derating used if above 1000m; B) Ambient Temperature: -25℃~55℃. C) Relative Humidity: ≤95%; D) As to the installation site, to make sure no bad effect on transformer insulation, chemical deposition, dust, and other explosive or erosive medium. E) The supply voltage approximates sinusoidal wave, and the three-phase voltage is relatively balanced.
