Can you live under high-voltage lines?

don't live, the electromagnetic field is very harmful, the lowest point of the high-voltage line is not less than 6 meters from the ground, and if there is a house, the distance will be reduced, which is easy to cause discharge, which is quite dangerous. Besides, it is expressly forbidden to store sundries under high-voltage lines.

No, according to the Detailed Rules for the Implementation of the Regulations on the Protection of Electronic Facilities, when calculating the maximum wind deflection of the conductor, the horizontal safe distance from the building is as follows:

1 meter below 1 kV;

1kV-1kV is 1.5m;

35kV is 3m;

66kV-11kV is 4m;

154kV-22kV is 5m;

33kV is 6m;

5kV is 8.5 meters.

as mentioned above, the safe distance between 5,-volt high-voltage lines and houses should not be less than 8.5 meters from the perspective of power safety; From the perspective of electromagnetic radiation, it shall not be less than 15m. If it is a 7,-volt high-voltage line, it is farther away from the safe distance of houses.

For the sake of safety, it is better to stay away from high pressure [cool drag] [cool drag] [cool drag ]

According to my knowledge, this question can be answered from both practical and scientific aspects.

In reality, high-voltage lines will still cause obstacles, such as the obstacles caused by towers to traffic, the impact of high-voltage lines on the beautiful environment and so on. It can be said that if you can choose, avoid high-voltage lines, and avoid them if you can, especially for buying real estate, building houses for self-occupation, planting tall trees and so on. This is easy to understand, so I won't discuss it.

Many people talk about the color change of high-voltage lines, and even feel fear when they see them. This fear stems from our lack of understanding of high-voltage lines. Scientifically speaking, as long as it is outside the specified distance, high-voltage lines have no influence on people's safety and health.

when it comes to science, we can discuss it in depth and dispel unnecessary doubts.

(1) Many people are worried about the so-called electromagnetic radiation. Electromagnetic radiation refers to the phenomenon that energy propagates through space in the form of electromagnetic waves. Electromagnetic radiation is divided into polar electromagnetic radiation, radio frequency electromagnetic radiation and power frequency electromagnetic radiation. Electromagnetic radiation can only be generated by high-frequency electromagnetic waves, such as high-frequency equipment such as launch pads and medical CT machines, and the frequency is generally as high as thousands or even tens of millions of megahertz. When the frequency of electromagnetic wave is low, energy can only spread by means of conductors (such as transmission lines), and will not overflow.

however, even if the voltage level is higher, the frequency of power facilities is only 5 Hz, and the wavelength is very long, which is a kind of power frequency electromagnetic radiation, which is the same as that of electric light bulbs used at home, and it cannot produce effective electromagnetic radiation to the surrounding environment at all.

objectively speaking, if electromagnetic radiation is harmful to human body, it is better to worry more about electromagnetic radiation generated by mobile phones than about high-voltage lines. In comparison, the radiation effect produced by the latter is more than a thousand times. It can be asserted that there is no commonly understood electromagnetic radiation problem in high-voltage lines.

(2) The second scientific concept is the influence of power frequency electric field. According to the national standard, the electric field intensity does not exceed 4 kV/m, and the magnetic induction intensity does not exceed 1 micro Tesla. The phenomenon that lighting tubes are lit in the environment of EHV substation seems horrible, but on the other hand, the operating personnel on duty in the substation have worked in this environment for decades all the year round, which proves that at least it has little impact on human body. More importantly, the magnitude of the power frequency electric field has a great relationship with the distance. When it is 5 meters away from the high-voltage line, the magnitude of the electric field and magnetic field is basically the intrinsic value of the environment, and it will not be greater than the electric field and magnetic field when the household appliances are working. (3) The high-voltage line has a concept of safe distance. Many people don't understand this concept, or even have never heard of it, but many people have an intuitive feeling, that is, don't go near high-voltage lines. This feeling is right. Being close to high-voltage lines or high-voltage equipment is sometimes devastating to the human body, so the electric power management department in some areas will hang the slogan "3 meters discharge" on the high-voltage line towers to warn people. High voltage discharge is electric energy differential discharge. As long as the voltage is high enough, electric energy can be released through air, which seems to be an insulating medium, thus causing harm to people or things. So if you pay enough attention to the news, you will find that some people were injured by high-voltage lines while fishing, and some people climbed the high-voltage line tower and were electrocuted into a fireball.

So, let's answer the question of whether we can live under high-voltage lines. As said at the beginning of the article, avoid it if you can. I put forward this conclusion more about personal injury than electromagnetic radiation that many people are worried about. We should remind ourselves more, educate our children not to approach near high-voltage lines, and put an end to seemingly harmless behaviors such as flying kites and throwing fish near high-voltage lines.

If you think that many high-voltage lines in rural areas are built on farmland, you will know that they are definitely uninhabitable. Many rivers with high-voltage lines will put up signs, which are dangerous for high voltage and prohibit fishing.

I can't live. The electromagnetic field around the high-voltage line is particularly strong, which will have adverse effects on people for a long time. The house with good feng shui is not built under the high-voltage line!

it is uninhabitable under high-voltage lines, and there will be radiation.

Safety standard for electromagnetic radiation

The allowable radiation intensity standard of environmental electromagnetic waves is divided into two levels, with the threshold value of electromagnetic wave radiation intensity and its frequency band characteristics that may cause potential adverse effects on human body as the boundary.

The first-class standard

is a safe area, which refers to an area where all people (including infants, pregnant women, the elderly, the sick and the disabled) who live, work and live for a long time under the electromagnetic wave intensity of this environment will not be adversely affected; Newly built, rebuilt or expanded transmitting antennas such as radio stations, TV stations and radar stations must meet the requirements of "first-class standards" in their residential coverage areas.

2 The secondary standard

is the middle area, which refers to the area where all people who live, work and live for a long time (including infants, pregnant women, the elderly, the sick and the disabled) may cause potential adverse reactions under the electromagnetic wave intensity of this environment; Factories and institutions can be built in this area, but when residential buildings, schools, hospitals and sanatoriums are allowed to be built, appropriate protective measures must be taken.

areas exceeding the second-class standard may have harmful effects on human body; This area can be used for greening or planting crops, but it is forbidden to build residential buildings and all public facilities where people often move, such as institutions, factories, shops and theaters; If these buildings already exist in this area, measures should be taken or the radiation time should be limited.

legal standards are also stipulated by the electric industry.

as long as the safe distance between the voltage level and this part can be ensured.

Personally, I suggest that people should not live under the high-voltage line. Are you kidding? Do you know how much current it can generate? There are tens of thousands of volts, and some of them are hundreds of millions of volts. If something goes wrong at all, there is nothing to live in. This is a hidden danger that threatens people's lives and property, and we must resolutely put an end to it.
