What is an electrified railway, an explanation of an electrified railway

To put it bluntly, an electrified railway is a railway that provides the operating conditions for electric locomotives.

The electrified railway is to supply power locomotives, and it is also to maintain the power supply equipment of the entire railway.

Hello, kiss <>

Railway electrification is engaged in locomotive testing, operation, maintenance and other work. Electrified railways, referred to as electrified railways, refer to railways that can run with electric power trains, because the lines of such railways need to be equipped with corresponding electrification equipment to provide power guarantee for the trains. The electrified railway technology major cultivates senior application-oriented technical talents with basic knowledge of electric locomotive crew and maintenance and basic car resistance skills.

There are two training directions in this major: electric locomotive and railway power supply. Cultivate professional talents with solid theoretical basic knowledge and strong practical work.

Explanation of electrified railways: modern railways that use electric locomotives as the traction power of trains. It is characterized by fast running speed, large transportation capacity, and no air pollution, which is suitable for use in areas with busy transportation, large road slopes and long tunnels. The world's first electrified railway was built in May 1879 in Berlin, Germany.

China's first electrified Senshu railway was the Baoji-Fengzhou section of the Baocheng Line, which was completed in August 1961.

Word decomposition Explanation of electricity Commonly known as electricity. Qing Youyang's "The Legend of the Female Thief": "Gu Huang Village Yedian, the twilight is miserable, there is no way to get rid of its danger, the atrium vibrates, like touching electricity, and the ears tremble and laugh.

Twenty Years of Witnessing the Strange Status Quo Chapter 97: "Foreigners often say that there is no thunder, but it is just an accidental touch of electricity. Interpretation of the railway A type of travel passage or track, made of steel rails, which were previously made of wood, but are now usually made of steel, usually made of two lines of rails connected to each other, forming a permanent road for vehicles to travel; A road with two or more tracks laid in this form is explained in detail as a "road".

There are rails for the train.

Railway electrification refers to the railway that can run with electric power trains, and it is named because the corresponding electrification equipment is required along the lines of this type of railway to provide power guarantee for the trains.

Electrified railways came about with the advent of electric locomotives, because electric locomotives do not carry their own energy, and they need the power supply system along the railway to continuously transmit electrical energy to drive the vehicles. Because electric locomotives have a stronger capacity advantage than diesel locomotives, the transportation capacity of electrified railways at the same scale far exceeds that of non-electrified railways, and has become the mainstream type of modern railways.

Electrified railways are widely used in the construction of high-speed railways and urban rail transit, and many non-electrified railways have also been upgraded and upgraded. However, the construction of electrified railways is demanding and difficult, and it is not suitable for some special geographical environments, so electrified railways cannot completely replace non-electrified railways.

The components of an electrified railway include:

1. Traction power supply system: It is the core of the electrified railway, providing DC or AC power. In addition to the construction of the power grid, the power supply system must also transmit its power to the railway line and ensure the quality and stability of the power.

2. Overhead line system: It is an elevated line facility on both sides of the railway line, which transmits the electric energy from the power supply system to locomotives and vehicles. Overhead lines generally use flat wires, which are suspended on both sides of the railway line by steel rods, ears, load-bearing cables and other brackets.

3. Power supply system: including catenary, insulators, ground or wires, cables and protection devices and other equipment, which are connected to form an overhead line system.

4. Traction substation: It is an important facility of the electrified railway, which converts the received alternating current or direct current into the voltage, current and frequency and other parameters on the catenary according to the needs for the locomotive traction facilities. Traction substations are generally built in the middle of overhead lines.

5. Locomotives and vehicles: In the operation of electrified railways, locomotives and vehicles use the power provided by the traction power supply system as a power source to complete the transportation of goods or personnel. In order to adapt to the use of electrified railways, locomotives and vehicles need to modify their internal electrical devices to better adapt to the power needs of the catenary.

Advantages of electrified railways

1. Increase the gravitational force of the traction: the electrified railway adopts electric traction locomotives and vehicles, which are more efficient than the fuel power drive of traditional locomotives, and the traction is more powerful for large-scale transportation of vehicles.

2. Reduce pollution: Electricity, as the power of electrified railways, reduces the amount of exhaust gas emitted by locomotives and vehicles during operation, reduces air pollution, and makes railway operation more environmentally friendly.

3. Improve transportation efficiency: Electrified railways have high operating efficiency and fast speed, which can reduce the duration and improve transportation efficiency. Moreover, multi-lane and multi-line railways are also one of the characteristics of electrified railways, which can make multiple trains run on one line at the same time, improve the utilization rate of the line, and reduce time-consuming.

4. Improve safety: The traction power supply of the electrified railway is transmitted to the locomotive and vehicle through the overhead line, which can make the fire hazard caused by other types such as exhaust pipe, oil leakage of the transmission system, and flying coal dust during the operation of the railway, and also reduce the potential safety hazard of the slag mass during driving.

Electrified railways have the advantages and functions of higher traction, lower environmental pollution, efficient and fast transportation, safety and reliability, etc., so they have been widely used and promoted in modern railway transportation.

Summary. Qinqin, electrified railway, referred to as electrified railway, refers to the railway that can run with electric power trains, because the lines of this kind of railway need to be equipped with corresponding electrification equipment to provide power guarantee for the train.

The construction of electrified railways in China began after the founding of the People's Republic of China. On August 15, 1961, China's first electrified railway was built in the newly built Baoji to Fengzhou section of the Baocheng Line; The total length is 91 km. In the 70s of the 20th century, in order to speed up the construction of the southwest, the electrification project of each section of the Baocheng Line from Fengzhou to Chengdu was restarted, and on July 1, 1975, the 676km Baocheng Railway was completed and opened to traffic.

Its completion has had a significant impact on the history of railway construction in China. In September 1975, the section from Xiangfan to Ankang, in March 1978 from Shijiazhuang to Yangquan, and in May of the same year, the section from Baoji to Tianshui was also started. In the past, construction was only carried out in one section of one line, but now, construction is carried out on several lines at the same time, and the development of the mountain railway to the main trunk line with heavy transportation has begun, and from the single-line electrification to the double-line electrification.

By the end of 1980, 1,680km of electrified railways had been built successively, including the whole line of Baocheng Railway, Yang'an Line, Xiangfan-Ankang section of Xiangyu Line, Shijiazhuang-Yangquan section of Shitai Line, and Baoji-Tianshui section of Baolan Line.
