What is the power of the Harmony EMU provided

Electricity. CRRC Zhuzhou Motor provided the YQ-625 traction motor and TBQ55-6300 25 traction main transformer for the "CR400AF", and the operation of the YQ-625 traction main transformer was in good condition, and the operation assessment of 600,000 kilometers was completed without failure.

On October 26, 2016, the EMU completed the last day of passenger operation on the Shenyang-Dalian Expressway Line, marking the official completion of all the tests of the "CR400AF" Chinese standard EMU from July 24, with a cumulative mileage of 600,000 kilometers.

In the test, the YQ-625 traction motor independently developed by CRRC Zhuzhou Motor and the bid-winning dynamic traction transformer were installed on the "CR400AF", which not only helped the EMU run out of the "world new speed", but also used the most reliable product quality, the strongest technical strength and the most stable power output.

Electricity, there is a powered carriage in the carriage, so that the total power increases, there will be high speed. EMU is a unit that combines a powered power car and a non-powered car according to predetermined parameters, and is a passenger train equipped with modern service facilities that can be driven at both ends.

There are two kinds of traction power distribution mode of EMU, one is called power dispersion, the other is called power concentration, and the advantage of power dispersion electric unit is that the power unit is distributed in different positions of the train, which can achieve greater traction force and flexible marshalling.

Because there are many wheelsets using power braking, the braking efficiency is high, and the speed regulation performance is good, and the braking deceleration is large, which is suitable for the line with more speed limit sections. In addition, the failure of the traction power of one EMU in the train has little impact on the traction index of the whole train.

Electricity. EMUs, basically the "Harmony" EMUs seen in China are electric, only the Harmony Great Wall of the S2 line in the suburbs of Beijing is an exception, it is an internal combustion EMU.

Harmony EMU is an electric EMU, the electric EMU relies on the external transmission of electric energy, the electric energy comes from the ordinary power plant, and then through the substation voltage transformation to the catenary (see a lot of poles on the side of the railway, the above is the catenary), the pantograph of the locomotive is in contact with the catenary, so as to lead the power into the locomotive, and then through the transformer, the rectification is sent to the traction motor traction EMU to drive.

Electricity, Harmony is an electric unit.

The Harmony is a power-dispersed train group, which is divided into an EMU (M) and a trailer (T), and the EMU has power when it is running. The grouping method is as follows:

CHR1B power configuration: 4 (2m + 1t) + 2 (1m + 1t);

CHR2 power configuration: 4m+4t;

CHR2B power configuration: 8m+8t;

CHR5 power configuration: (3M+1T)+(2M+2T).

Electricity, each carriage has a power drive, hence the name EMU.

The front end of the Type 2 is all powerless, and the other models don't know much about it.

The power unit is dispersed on each carriage to make it both traction and passenger, and such a passenger car is called an EMU. The EMU is a group of several self-powered vehicles and several unpowered vehicles. Powered vehicles are called bullet trains, and unpowered vehicles are called trailer groups.

EMU technology originated from the subway and is a power dispersion technology. Under normal circumstances, the ordinary trains we take rely on locomotives to pull them, and the carriages themselves do not have power, which is a power concentration technology. The train that adopts the "EMU", the carriage itself also has power, and when it runs, it is not only driven by the locomotive, but also the carriage will "run by itself", so that the power is dispersed and the effect of high speed can be achieved.

The advantages of EMUs are:

The EMU has cabs at both ends, so there is no need to unhook the locomotive at one end and then move it to the other end when the train turns around, which greatly speeds up the operation. At the same time, it also reduces the workload of vehicle maintenance personnel and improves safety. (The locomotive can also be operated by pushing and pulling to achieve the same effect).

EMUs can be easily combined to train different lengths and shortages. In some places, EMUs will be formed into a train first, and then split into several sections at the station on the way, and drive to different destinations.

1. Electric EMUs refer to EMUs that drive traction motors through catenary or power rail power supply, and are subdivided into two categories: DC electric units and AC electric units. Electric multiple units are a special type of electric locomotive that runs in electrified railways.

2. Diesel EMU is a kind of power distributed railway vehicle driven by diesel engine. Compared with the centralized power of railway vehicles, it has better acceleration and deceleration performance, more average weight distribution, and lower loss to rail.

The power of the EMU train is the locomotive, as the saying goes, "the train runs fast because of the headband". Of course, the front of the EMU is powered by electricity. Nowadays, many trains rely on electricity, depending on what trains run and where, and there are very few oil-burning trains, mainly concentrated in short-distance or remote areas.

Hello landlord! The power of the ordinary train** is the main locomotive from this train, that is, the locomotive, if it is pulled by a diesel locomotive, it relies on burning coal to provide energy, and if it is an electric locomotive traction, it is powered by the pantograph on the locomotive as an energy source. The power supply method of bullet train and high-speed rail is the same as that of electric locomotive, I hope my answer can help you!

EMUs are powered by electricity.

But there are also diesel motor vehicle groups.

Other trains also rely on electricity, and a small number rely on internal combustion engines...

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

1.In the past, trains were pulled by diesel locomotives, and only the locomotive was powered, and diesel fuel was burned. Today's EMUs and even high-speed railways have been fully electrified, and each carriage of the EMU has power, which is powered by a high-voltage catenary erected above the track, and the "pantograph" on the top of the locomotive will introduce the power into the high-power motor in the car, which converts the electric energy into power and pushes the train forward.

2.The top of each EMU is equipped with a pantograph, and the pantograph receives electric energy from the catenary, such as C pantograph receives high-voltage alternating current from the catenary, and is reduced to a lower alternating current through the main transformer installed on the undercarriage, and the alternating current after the step-down is converted into direct current through the converter on the grid side, and the direct current is then converted into a three-phase alternating current of variable frequency and variable voltage by the traction inverter and sent to the traction motor, and the electric energy is converted into the mechanical energy of the traction train. The electric unit adopts the composite braking mode, the EMU adopts electric braking, and the trailer adopts air braking; The electric braking of the motor vehicle takes precedence, and when the electric braking in the low-speed area stops working or when the electric braking fails, the insufficient part is supplemented by the air braking.

3.The particularity of high-speed rail: its speed is 350 kilometers, drilling holes in the mountains, building bridges on the road, completely detached from the ground, not affected by the nature of the ground, and not affected by the complex human and animal tracks, 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 the cement pier, so that it is foolproof.

EMUs include diesel EMUs and electric EMUs1.The power of diesel multiple units is a diesel engine2.Electric EMUs rely on external transmission of electrical energy, and the electrical energy comes from ordinary power plants.

The concept of EMU is to change the power unit of the train from one to many, like the power centralized EMU Shenzhou, the two ends are the locomotives and the middle is the unpowered carriage, so that the traction required for starting is dispersed without a large starting torque, and the overall braking reaction time of the train is shorter than that of ordinary trains.

Shenzhen Pingdi, Zhenqin Company, what is the power pack producing.

I don't know if you want to get a general idea or if you want to learn more. Let me briefly introduce it, its main circuit is as follows: overhead line - roof pantograph - transformer - vacuum circuit breaker - high-voltage isolation switch - voltage transformer - current transformer - single-phase converter - three-phase squirrel cage motor - speed sensor.

At present, EMUs of 300km and above are divided into eight trains, with a total of two pantographs, a vacuum circuit breaker and a high-voltage isolation switch, two traction converters, and eight motors.

The auxiliary power supply system is powered by the auxiliary main winding, which is more complex and involves a lot of power electronics technology.
