Product Description  

CJY30/9G (p) overhead line electric locomotive, 30 tons of stringing locomotives, stringing variable-frequency adjustable-speed locomotives, variable-frequency adjustable-speed locomotive
30 ton line vvvf locomotive was carefully research the company after many years of practice, successfully developed, its good design, is a practical product, advanced technology, innovative design, the locomotive driver's comfort, safety and reliability, energy efficiency is an ideal product.
JY30/9G (p) frame line type electric locomotive used international advanced of VVVF Exchange frequency transformer adjustable speed technology, will frame line of DC electric through high-power IGBT components inverse becomes frequency can adjustable of three-phase Exchange electric, drive three-phase motor as locomotive power, due to used has VVVF control technology, makes three-phase motor reached and over DC motor of up moving turned moments and traction characteristics, makes locomotive with overload up moving strong powerful. It compared with a conventional DC locomotive, damage control of AC motor, controller, no contacts and no wear, and braking the mechanical energy into electrical energy to give back.
Working principle:
Wiring DC550V power grid through overhead supply inverter, inverter DC needed to reverse motor three-phase AC, three phase alternating current three-phase AC traction motors and motorbikes being driven through gearbox, drive shaft and so on.
