Three-phase transformer SG-8k

isolationdryfor railway applications

Product Overview: This transformer is a rail transit energy conversion linchpin. It powers frequency converters, crucial for train power, signal, and auxiliaries, aiding safe and orderly rail transit. Specific Introduction: 1.High-Permeability Sheets: These sheets underpin the transformer's efficient running. When powering converters, they promptly answer magnetic field changes, cut magnetic hysteresis loss, speed up energy conversion response and accuracy, and guarantee stable output voltage, meeting rail equipment's strict energy quality specs. 2.Overload Capacity Pledge: It has hefty overload capacity. Its structure and materials endure overload current and vibration shocks in rail transit. When overloaded, it stabilizes output voltage and current via its own mechanism, warding off equipment failures and ensuring train operation's continuity and reliability. 3.Electrical Isolation & Monitoring: The vacuum impregnation nails excellent electrical isolation, barring current leakage and short circuits. The PT100 temperature monitor tracks operating temperature in real-time, easing early anomaly discovery and ensuring the transformer's safe operation in rail's complex EM field. 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.
