Rail Transit

Rail TransitThe power supply system of rail transit has the characteristics of severe load fluctuations, frequent train starts and stops, concentrated impact loads, and dense rectifier and inverter equipment. During operation, problems such as grid harmonic distortion, reactive power fluctuations, voltage flicker, and surge current impact are prone to occur, which can easily cause power supply instability, equipment overheating loss, protection misoperation, and other hidden dangers, directly affecting the safety, punctuality, and continuous operation of rail transit.
As the key core equipment of the rail transit power supply system, our transformers and reactors rely on strong overload resistance, low loss, high insulation, and anti fatigue characteristics to achieve precise voltage reduction, electrical isolation and rectification adaptation, stable transmission of electrical energy in the power grid, reduce power supply losses and temperature rise risks, and ensure the continuous and reliable operation of the power supply system. Supporting various types of reactors effectively suppresses harmonic interference generated by rectification equipment, limits closing and fault surge currents, balances system reactive power, stabilizes bus voltage, improves voltage flicker and low power factor caused by load fluctuations, purifies power supply waveforms, and enhances grid operation stability.
