High -voltage lines usually refer to transmission lines with voltage above 10kV (including 10kV).The voltage levels of domestic high -voltage lines are generally divided into: 35kV, 110kV, 220kV, 330kV, 500KV, 750KV, etc.110kV and 330kV are mostly used in the northern region.Generally known as the transmission voltage below 220 kV is called high voltage transmission, the transmission voltage from 330 to 750 kV is called ultra -high voltage transmission, and transmission voltage of more than 1,000 kV is called UHV transmission.
High -voltage line protection plan
The purpose of the high -voltage line protection solution: For any project, there will be a certain purpose, and the high -voltage line protection is also a purpose.Its main purpose is to ensure the normal transportation of the power supply and not bring dangerous threats to others.And when designing the scheme, you also need to pay attention to the method of the scheme, such as elevated wires or deep -buried wires, and so on.Basis of high -voltage line protection solutions: For high -voltage line protection solutions, the construction basis is very important. It can be said that it has certain guiding significance for the entire construction.For the basis, sometimes there will be related power design institutes to formulate related formulation.Construction of high -voltage line protection schemes: For the construction unit in the plan, choose the designated department, or a power company with relevant qualifications to carry out construction.For some other engineering companies that do not have power -related qualifications, they must not bear this project.Acceptance of high -voltage line protection schemes: The acceptance can be selected for third parties for acceptance. The standards for acceptance are related to the formulation of the power department.Because the power department has professional skills and knowledge, related experience is also very rich.
The impact of high -voltage lines on houses
First, it is likely to be one of the causes of leukemia.Medical research has proved that in the environment of high -electromagnetic radiation for a long time, blood, lymph fluid and cell original primary quality will change.After research, Italian experts believe that more than 400 children in the country suffer from leukemia each year. The main reason is that it is too close to the high -voltage wire, which has been severely polluted by electromagnetic pollution.2. Can induce cancer and accelerate the proliferation of cancer cells in the human body.Electromagnetic radiation pollution can affect the human bodys circulatory system, immune, reproduction and metabolic functions. It will also induce cancer and accelerate the proliferation of cancer cells in the human body.Swiss research materials pointed out that residents who surrounded by high -voltage lines have a probability of 7.4 times higher than ordinary people.The results of the sampling tests made by some patients with electromagnetic radiation injuries in the U.S. Cancer Medical Foundation in the United States showed that the growth rate of cancer cells working near high -voltage lines is 24 times faster than the average person.Third, the reproductive system that affects people is mainly manifested as a reduction in mens quality, natural abortion and fetal malformations in pregnant women.Fourth, it can lead to childrens intelligence.According to the latest survey, 350,000 of the 20 million children born in my country each year are defective, of which 250,000 are intellectual disability. Some experts believe that electromagnetic radiation is also one of the factors affecting factors.The World Health Organization believes that the electromagnetic radiation of computers, televisions, and mobile phones has a adverse effect on the fetus.
High -pressure line safety distance
The height of the low -voltage line through the safety of the residential area is above six meters, and it is absolutely not below five meters in non -residential areas.Compared with the low -voltage line, the mid -voltage line should be higher than its certain limit.It is mainly to say that the safety distance of the high-voltage line is 4 meters away from the voltage below one kilo, and the voltage height increases the safety distance. In short, the safety distance range of the high-voltage line is between 4-15 meters.
