1 10 What is the safe distance of the high-voltage line?

According to geomantic omen, it has influence within the range of 100 meters. Your distance is fine. \ r \ Scientifically speaking, the substation is 5 meters. \ r \ According to the relevant regulations on the protection of power facilities, for an overhead transmission line of 1 10 kV substation, the protection area is10m outside the line, in other words, as long as it is away from the power line10m, the protection areas are/for 220kV and 500kV transmission and transformation system conductors respectively. \r\n \ r \ The safety distance of outdoor box-type substation is specified as follows: 6KV is 0.7m, and 0.4KV is the low voltage side, as long as it is not touched. The so-called safe distance is the minimum distance between human body and charged body. I think your picture shows that the distance between the transformer room and the building is 0.8m, which is farther from the transformer inside. Safe distance is enough. However, the electromagnetic interference you mentioned depends on the quality of the screen wall of the substation. When it comes to noise, it must have an impact. The following are the safe distances for other voltage levels for reference, and the units are (KV)\r\n 10KV and below 0.7m, 35KV 1.0,1/kloc-0. 330KV4.0, 500KV5.0 \ r \ nWhat is the radiation distance of substation \ r \ nTo understand the influence of electromagnetic radiation on human body, we must first have a scientific and objective understanding of electromagnetic radiation. The electromagnetic radiation of transmission lines and substations belongs to extremely low frequency (50HZ, also known as power frequency) electromagnetic radiation, which is different from other high frequency radiation (such as mobile phones). Moreover, the electromagnetic radiation generated in the process of power transmission will drop sharply with the increase of distance. Therefore, the workers who are on duty in substations and power plants for a long time will not be affected by electromagnetic radiation when they work outside the safe distance of electric shock. According to the national requirements, all power transmission and transformation projects have been evaluated and approved by the environmental protection department to ensure that electromagnetic radiation has no adverse effects on the public. \ r \ It is forbidden to build under high-voltage lines. The wires on the roofs of these residents have relevant regulations on the planning and protection of power facilities, all of which are 1 10000 volts, which will produce strong radiation and be harmful to human health. In addition, because the voltage is as high as 1 10000 volts, the conductor equipment may fail, and the source \ r \ n \ r \ foreign experts come to the conclusion from the perspective of epidemiological investigation, which is harmful; \ r \ Domestic experts have concluded that it is "harmless" from an electrical point of view. \r\n\r\n2. Who is most affected by high-voltage lines \r\nChildren are greatly affected, but adults are not. \r\n\r\n3. What is the impact of high-voltage lines? \ r \ Conclusion of British epidemiologists: The incidence of leukemia in children living in electromagnetic radiation environment is one in 700, which is twice as high as that in children living in non-electromagnetic radiation environment (1400). \ r \ n \ r \ Conclusion of Swedish National Committee for Industry and Technology Development: 1 and 1.5 years old children are more than 2.7 times more likely to develop leukemia if they are exposed to an environment with an average magnetic induction intensity greater than 0.2 microtesla; 2. If the magnetic induction is greater than 0.3 micro Tesla, it is 3.8 times. \ r \ n \ r \ The conclusion of California Health Science Assessment Agency: "Electromagnetic field can increase the risk of childhood leukemia, adult malignant brain tumor, amyotrophic lateral sclerosis, abortion and so on. To some extent, this may lead to suicide and adult leukemia. " \r\n\r\n4。 What effect does high-voltage line have on people? What is its safety index value? \ r \ n \ r \ High-voltage lines transmit large current, and the magnetic field generated by the large current has an impact on people's health. \ r \ n \ r \ British experts believe that the safe value of magnetic field generated by high-voltage lines is 0.4 micro Tesla (μt), above which children will face the risk of illness. \r\n\r\n5。 What is the safe distance of the high-voltage line? \r\n220 kV high-voltage line 100 meter, the electromagnetic radiation intensity exceeds 0.4 micro Tesla; \ r \ n 132kV high-voltage line has an electromagnetic radiation intensity exceeding 0.4 micro Tesla within several tens of meters; \r\n 1 1-66 kV high-voltage lines have an electromagnetic radiation intensity exceeding 0.4 microtesla within a range of more than ten meters; \ r \ The electromagnetic radiation intensity of high-voltage lines buried in the ground only exceeds 0.4 micro Tesla within a few meters. \r\n\r\n6。 China's high-voltage line construction standards are far from meeting the safety requirements. \ r \ According to Chinese standards, the construction standard of high-voltage lines can be met if the magnetic induction intensity is lower than 100 micro Tesla. \r\n\r\n7。 The impact of high-voltage lines on real estate has already appeared \ r \ People have found that the impact of high-voltage lines on real estate has begun, 1 and the rental price of houses near high-voltage lines has dropped; 2. The sale of second-hand houses next to high-voltage lines is also affected. High-voltage lines make the house that has worked hard for a lifetime face depreciation; \ r \ Developers also found that the sales of houses near high-voltage lines were not smooth. The safe distance between outdoor and it shall not be less than 8 meters.
