Introduction to Power Trains, What is the Power Source of Trains?

The "power train" formed by Yan Zhilin and You Qiuxing has always allowed Taiwan's ** workers to see a positive and inspiring force. Their civilian down-to-earth style, working hard to win the applause and attention they deserve, has created a sincere and vibrant prototype for the Taiwanese music scene and the Asian music industry. Since their debut in 1997, their method of winning the support of fans has been the most direct and laborious way, singing live from place to place, shouting hard sentence by sentence.

Every time a new ** is born, there are nearly 100 singing activities that are closest to the fans, and the super popularity charm of the power train is accumulated bit by bit. In 1999, Power Train embarked on an Asian tour. The power train standing on the world stage is not only the pride of the aborigines, but also the pride of the Taiwanese people.

At the same time, the power train will also launch the latest**"Betrayal Love Song", which was collected as early as the beginning of 1998, and the production period lasted for half a year, making "Betrayal Love Song" full of possibilities on **, and it is also the most content-rich one since the power train became famous. After getting acquainted with the sound of this super-heavy firepower duo, "Love Song of Betrayal" began to let fans know the more different possibilities of the power train, so ** in it, not only includes the genre with live explosive power, but also the lyrical, blues, lyrical rock, nostalgic dance music and heavy metal ** nature. It will definitely amaze the fans and appreciate the most complete ** style of the power train.

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

1.In the past, trains were pulled by diesel locomotives, and only locomotives were used.

There is power, and it burns diesel. Today's EMUs.

So much so that the high-speed rail has been fully electrified, and each carriage of the EMU has power, which is powered by the high-voltage catenary erected above the track, and the "pantograph" on the top of the locomotive introduces the power into the high-power motor in the car, 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.

Yes, the direct current then passes through the traction inverter.

Converted into three-phase alternating current with variable frequency and variable voltage.

It is sent to the traction motor to convert the electrical energy 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.

Trains are divided into three categories: electric locomotives, diesel locomotives, and steam locomotives.

The original trains were pulled by ropes or horses. By the 19th century, most trains were pulled by steam locomotives. After the 1940s, steam locomotives were gradually replaced by diesel locomotives, which were cleaner and required less labour, and later electric locomotives and EMUs appeared.

The initial investment in electrified railways is significant, but the operating costs are the lowest per mile. Therefore, only high-traffic lines are suitable for electrification. Electrified trains may use overhead cables or third rails for electricity.

The efficiency of the power locomotive is calculated by dividing the unit kilowatt (kW) by the weight metric ton (ton) that can be towed, which is called the traction capacity ratio, and the steam locomotive has the lowest efficiency, followed by the diesel locomotive (the electric transmission is more efficient than the hydraulic transmission), and the electric locomotive or electric combination is relatively more economical. This is because no additional kinetic energy is required to pull the engine that generates power.

The traction kinetic energy ratio from small platoon to large is: (passenger aircraft, motorcycles, general family cars, trucks running on highways, agricultural tractors, trailers,) steam locomotives, diesel hydraulic transmission locomotives, diesel-electric transmission locomotives, electric locomotives, diesel EMUs, high-speed rail EMUs, electric EMUs (passenger ferries, fishing boats, oil tankers).
