Metro rail auxiliary converter

Subway/Light Rail Auxiliary Converter is mainly used in Urban Rail Transit Vehicle Auxiliary Power Supply System, which includes Inverter Unit and Converter Unit to supply power for medium and low voltage electrical equipment of vehicles.

Auxiliary Power Unit

Monorail traffic system is an important part of urban traffic system, which has the advantages of saving floor space and relieving traffic pressure, and has strong adaptability to complex terrain.

Pulling motor

Subway traction motor adopts three-phase rat cage asynchronous electric motor, using frequency conversion and variable voltage speed regulation mode. The traction converter output three-phase AC power to power the stator winding of the traction motor.The rotating magnetic field is generated on the motor stator winding, which cuts the rotor conductor to sense the electromotive force and current. The rotor conductor is exerted by the electromagnetic force under the action of the magnetic field, forming the electromagnetic torque, driving the motor rotation, converting the electric energy into mechanical energy, and driving the train to run.

Metro traction converter

Metro/light rail traction converter is mainly used in the traction system of urban rail transit vehicles. Its principle is to convert the power supply of catenary into the power supply needed by traction motor of vehicles to provide traction force and electric braking force for the whole vehicle.

Energy storage device

La batería y El sistema de gestión desarrollados independientemente por la compañía huashi reemplazaron la batería importada original del proyecto de tranvía Hexi Kirin y reemplazaron la batería con titanato de litio. en comparación con El litio ternario original, la Unidad termostática y la batería están integradas para ahorrar Espacio y reducir El ensamblaje de tornillos, lo que facilita El mantenimiento de la caja y reduce los costos de mantenimiento y El ciclo de respuesta.

Energy storage device

The energy storage device adopts lithium titanate battery, which has good safety, high and low temperature performance, long cycle life and wide working environment temperature range (-20℃~45℃). The battery is cooled by liquid, and the weight of the whole machine is less than 1500kG；. Each internal unit adopts modular design, which is easy to maintain; Communicate with the MVB network of the whole train. At the same time, the control unit of the whole train is provided with the maintenance Ethernet, and the BMS unit is provided with the maintenance CAN network to support the download and maintenance of fault information.

Water Cooling Device

The water-cooling device should be able to cool the temperature of the circulating fluid in the system to below 60℃, so as to ensure that the converter and traction motor can work normally under vehicle operation. The water cooling device shall automatically adjust the fan speed according to the water temperature at the outlet of the heat exchanger, so as to adjust the water supply temperature of the water cooling device. The water-cooling device uploads the running status and alarm information of the water-cooling device to the vehicle master control through communication.
