G 146 high-speed train timetable

G 146 high-speed train schedule: there are 10 stations, 15:2 1 departure, and arrive at the station on 2 1:05. The whole journey takes about 5 hours and 44 minutes. The passing stations are Shanghai Hongqiao Railway Station, Changzhou North Railway Station, Nanjing South Railway Station, Bengbu South Railway Station, Xuzhou East Railway Station, Qufu East Railway Station, Jinan West Railway Station, Dezhou East Railway Station, Tianjin South Railway Station and Beijing South Railway Station.

The driving power of high-speed rail comes from high-voltage electricity, and the power supply voltage of high-speed rail is 27.5 kV. This electricity comes from the power grid. After the power plant generates electricity (330, 220 or 1 10kV), it is sent to the railway traction substation through the transmission line, adjusted to the voltage suitable for high-speed rail, then sent to the catenary conductor through the catenary feeder, and then supplied to the train through the catenary.

The power source of high-speed rail is electric traction.

1. In the past, trains were drawn by diesel locomotives. Only locomotives have the power to burn diesel. Today's EMUs and even high-speed trains have been fully electrified. Each car of EMUs has power, which is provided by the high-voltage catenary erected above the track. The power is introduced into the high-power motor at the top of the locomotive, which converts electric energy into power and pushes the train forward.

2. Pantograph is installed at the top of each motor car, and it receives current from catenary to obtain electric energy. For example, the pantograph C receives high-voltage alternating current energy from the catenary, which is reduced to lower alternating current through the main transformer installed on the chassis, and the reduced alternating current is converted into DC energy through the grid-side converter, and then converted into variable-frequency and variable-voltage three-phase alternating current through the traction inverter, which is sent to the traction motor.

Convert electric energy into mechanical energy of traction train. EMU adopts compound braking mode, EMU adopts electric braking and trailer adopts air braking; Priority is given to the electric braking of motor trains. When the electric brake stops working or fails in the low-speed area, the insufficient part is supplemented by air brake.

3. The particularity of the high-speed rail: its speed is 350 kilometers per hour. It drills holes in the mountains and builds bridges along the road, completely leaving the ground, and is not affected by the nature on the ground, nor by the complex human and animal trajectories. It is an independent unit. As long as there is a high-speed rail line, the whole process is isolated, and the line is laid on a concrete pier, which is foolproof.
