It is recommended to negotiate with the Electric Power Bureau and ask the government to come forward to coordinate interests.
Because according to relevant power facility protection regulations, for a 110 kV substation overhead transmission line, its protection area is 10 meters outside the line. In other words, as long as it is 10 meters away from the wire In places where the safety of electromagnetic radiation is guaranteed. For 220 kV and 500 kV power transmission and transformation system wires, the protection areas are 15 meters and 20 meters respectively.
About the safety distance of outdoor box-type substations
The safety distance is stipulated in this way. The safety distance for 6KV is 0.7 meters, and 0.4KV is the low-voltage side. It does not require contact. The so-called The safe distance is the minimum distance between the human body and the electrified body. I see in your picture that the distance between the transformer room and the building is 0.8 meters, and the distance from the transformer inside is further, which is enough in terms of safety distance. But what you said Electromagnetic interference depends on whether the substation room screen is good or not. Speaking of noise, it will definitely have an impact. The following are the safety distances for other voltage levels for reference, unit (KV)
10KV and below 0.7 meters, 35KV 1.0 meters, 110KV 1.5 meters, 220 KV 3.0 meters, 330 KV 4.0 meters, 500KV 5.0 meters
What is the radiation distance of the substation
To understand the impact of electromagnetic radiation on To influence the human body, we must first have a scientific and objective understanding of electromagnetic radiation. The electromagnetic radiation from transmission lines and substations belongs to extremely low frequency (50HZ, also called power frequency) electromagnetic radiation, which is a different type from other high-frequency radiation (such as mobile phones). Moreover, the electromagnetic radiation generated during power transmission will attenuate sharply as the distance increases. Therefore, the health of workers who have been on duty in substations and power plants for a long time will not be affected by electromagnetic radiation while working at a safe distance from electric shock. According to national requirements, power transmission and transformation projects have undergone environmental assessment and approval by the environmental protection department to ensure that electromagnetic radiation has no adverse effects on the public
Building buildings under high-voltage lines is prohibited, as there are relevant regulations on planning and power facility protection.
The wires on the roofs of these residential buildings are all 110,000-volt high-voltage wires, which produce strong radiation and are harmful to the human body. In addition, because the voltage is as high as 110,000 volts and the wire equipment may malfunction, the source of the "harmful theory" and "harmless theory" of high-voltage wires in buildings
Foreign experts concluded from the perspective of epidemiological investigation that " "Harmful" conclusion;
Domestic experts came to the conclusion of "Harmless" from an electrical point of view.
2. Who has the greatest impact of high-voltage lines?
It has a greater impact on children and less on adults.
3. What is the impact of high-voltage lines?
British epidemiological investigators concluded that the incidence rate of leukemia in children living with electromagnetic radiation is one in 700, which is higher than the incidence rate (one in 1,400) of children living in areas without electromagnetic radiation. Out twice.
The Swedish National Council for Industrial and Technological Development concluded: 1. Children under the age of 15 who are exposed to an environment with an average magnetic induction intensity greater than 0.2 microtesla are more than 2.7 times more likely to develop leukemia than ordinary children; 2. If the magnetic sensitivity is greater than 0.3 micro Tesla, it is 3.8 times.
The conclusion of the California Health Science Evaluation Agency: "Electromagnetic fields can, to a certain extent, increase the risk of childhood leukemia, adult malignant brain tumors, amyotrophic lateral sclerosis, miscarriage, etc., and may cause Suicide and adult leukemia. ”
4. How do high voltage lines affect people? Its safety index value?
High current is transmitted in high-voltage lines, and the magnetic field generated by the large current has an impact on human health.
British experts believe that the safe value of the magnetic field generated by high-voltage lines is 0.4 microtesla (μt). Above this value, children will be at risk of illness.
5. What is the safe distance of high-voltage lines?
The electromagnetic radiation intensity of a 220 kV high-voltage line within a range of 100 meters exceeds 0.4 microtesla;
The electromagnetic radiation intensity of a 132 kV high-voltage line within a range of tens of meters Exceeding 0.4 microtesla;
The electromagnetic radiation intensity of 11-66 kV high-voltage lines within a range of more than ten meters exceeds 0.4 microtesla;
High-voltage lines buried underground The intensity of electromagnetic radiation exceeds 0.4 microtesla only within a few meters.
6. my country's high-voltage line construction standards are far from meeting safety requirements
my country's standards stipulate that high-voltage line construction standards are met if the magnetic induction intensity is less than 100 microtesla.
7. The impact of high-voltage lines on real estate has already appeared
Owners have discovered that the impact of high-voltage lines on real estate has already begun. 1. The rental prices of houses near high-voltage lines have dropped; 2. The sale of second-hand houses has also been affected. High-voltage lines have devalued the houses that have been worked hard for a lifetime;
Developers have also found that sales of houses near high-voltage lines are not going well. The safe distance from it outdoors shall not be less than 8 meters.
