The high-speed rail will not have to be built not far from the high-voltage line, and the high-speed rail will be repaired according to his route and needs, and it has nothing to do with the distance of the high-voltage line.
-
The high-voltage line is a dedicated line for transporting electricity, factory electricity, civil electricity, street lamps in the streets and alleys, all of which are transported by high-voltage lines, so high-voltage lines are not far from high-speed railways, but there must be high-voltage lines where there are high-speed rails, because high-speed railways need high-voltage electricity.
-
High-speed rail will be built not far from the high-voltage line, which is not necessarily, this is because the high-voltage line is used to transmit electricity, so the high-speed rail will not be repaired far from the high-voltage line.
-
The high-voltage line is not far away, and the high-speed rail will not necessarily be built, because there are many high-voltage lines that are civilian, and the power supply of factories, and have nothing to do with high-speed rail.
-
This is not necessarily, the primary task of the high-voltage line is to transmit electricity and solve the problem of people's daily electricity!
As for high-speed rail, the operation of high-speed rail requires high-voltage electricity, and all high-speed rail must have high-voltage lines!
On the other hand, if there is a high-voltage line, a high-speed rail must be built, which is not true!
-
High-voltage lines are not necessarily related to high-speed rail.
The main task of high-voltage lines is to transmit electricity over long distances. And not just for high-speed rail.
Many high-voltage lines are far from the city, in the mountains.
-
Not necessarily, there are many places with high-voltage lines, and not every place will build high-speed rail.
-
Not necessarily, there are a lot of high-voltage lines, and they don't necessarily have to build high-speed rail.
-
There is not necessarily a high-voltage line and there is a high-speed rail, but the high-speed rail is inseparable from the high-voltage circuit.
-
Not necessarily. Because the high-speed rail was designed according to the road map.
-
That's not always accurate. High-voltage lines are transmission lines, and high-speed rail are two different things.
-
No. 1. High-speed rail is for the country's transportation construction, to enhance the transportation and development of all parts of the country, and to promote economic exchanges.
2. High-voltage lines are also divided into (10kv, 35kv, 110kv, 220kv, 500kv, 750kv) according to the voltage level, and most of the lines are built by the power grid company in order to reduce the loss in the process of long-distance power transmission.
There is no inevitable causal relationship between the high-speed rail and the high-voltage line, so the relationship that the high-speed rail will be built not far from the high-voltage line cannot be established.
-
It is the high-speed rail that needs to be built around the high-voltage line. Because the operation of high-speed rail needs to be charged, the high-voltage line is to meet the energy supplement of high-speed rail operation.

From a circuit point of view, high-speed rail adopts the AT (autotransformer) power supply method. High-speed rail can run by relying on the traction power supply system to provide power to high-speed trains。Traction power supply is the primary load of the power system, with the exception of Germany, where the high-speed rail grid is independent of the German national grid.
Therefore, the high-speed rail traction power supply system includes overhead catenary, traction substation, and return loop.
The special equipment of AT power supply mode mainly includes a forward feeder erected parallel to the catenary and a low-impedance autotransformer set at certain intervals. The forward feeder is the path for the traction load to return to the substation, and its allowable ampacity should be equivalent to the allowable ampacity of the catenary. Autotransformer.
The ratio of turns of the primary and secondary windings is 2:1, one end is connected to the catenary, the other end is connected to the feeder, and the middle point is connected to the neutral point of the rail or choke transformer.
Characteristics of AT power supply mode
1. The power transmission voltage of the electric traction substation is 1 times higher than the working voltage of the electric locomotive, and the current in the traction network is only 1 2 of the current of the electric locomotive, so that the energy consumption and voltage loss of the traction network are reduced, and the power supply quality is improved.
2. The current in the catenary of AT1-AT3 is equal to the current of the forward feeder, and the direction is opposite, and the interference to the communication line cancels each other; The current I1 and I2 values in the catenary of AT3-AT4 are related to the position of the locomotive, but in opposite directions. Therefore, the AT power supply mode can greatly reduce the interference of the traction load to the communication line.
The above content refers to Encyclopedia - Electric Traction AT Power Supply Mode.

It is the catenary of the electric locomotive, with a voltage of 10,000 volts, which is used to supply power to the electric locomotive and EMU!!
A catenary is a special form of transmission line erected along the railway line to supply power to electric locomotives. It is composed of several parts: contact suspension, support device, positioning device, pillar and foundation.
The voltage level of China's catenary: power frequency single-phase AC system: 25kV catenary is responsible for the important task of directly transmitting the electric energy obtained from the traction substation to the electric locomotive. Therefore, the quality and working condition of the catenary will directly affect the transportation capacity of the electrified railway.
Domestic high-speed railways basically use electric EMUs, so domestic high-speed railways have catenary.

High-speed rail is an electric locomotive that requires electricity.

The International Health Organization (WHO) has confirmed that the power-frequency electromagnetic field generated by high-voltage transmission is a suspected carcinogen in humans. A large number of studies have also demonstrated the dispersion of power frequency electromagnetic fields and some other human diseases, such as neurological diseases. Residents, especially children and the elderly, are more sensitive to power-frequency electromagnetic fields and are more vulnerable.
Scientific research has also shown that the probability of leukemia and cancer in the range of 40 meters to 300 meters around the 220kV high-voltage line is several times that of other regions, and electromagnetic radiation can also cause miscarriage in pregnant women, fetal malformations and cardiovascular diseases, which is extremely harmful to people.
There are serious hazards within 6 meters of the 10,000-volt high-voltage line, 6 meters to 36 meters are more harmful, and more than 36 meters are less harmful and can be ignored;

The bird is both feet on a wire, the potential of the high-voltage wire is very high, but the potential of the transmission line at this end is about the same as the potential at that end, the voltage added to the two ends of the wire in the transmission line is not large, so as to ensure that the electrical energy is rarely lost on the wire, with the wire as a resistance, because the wire is hundreds of kilometers or even thousands of kilometers long, and the voltage added at both ends of the wire is hundreds of volts, calculate the distance of the bird's feet, the potential difference between the bird's feet can electrocute an ant has to put a question mark, we say that the high-voltage electricity is tens of thousands of volts that is the potential of the wireWhy are people electrocuted? Standing on the iron tower, the iron tower is connected to the ground, so it is like connecting people and the ground, and the electric potential of the ground is zero. Then the potential difference between the wire and the ground is the potential of the wire, isn't it normal to electrocute people? >>>More
At present, there are two kinds of high-voltage lines, one is only a few hundred euros, and the other is more than 10k euros. The automobile high-voltage wire, also known as the high-voltage ignition coil or high-voltage bag, is used to amplify the 12V voltage provided by the battery to 30000V, and release it through the central electrode and side electrode of the spark plug, thereby igniting the mixture. >>>More
