The impact of high voltage lines on residential buildings

Introduction The scope of influence of high voltage lines on residences. The safety distance for high voltage lines below 1 kV is 4 m; the safety distance for high voltage lines from 1 to 10 kV is 6 m;

The impact of high voltage lines on residential buildings

The safety distance for high voltage lines below 1 kV is 4 m; the safety distance for high voltage lines 1-10 kV is 6 m; the safety distance for high voltage lines 35-110 kV is 8 m; The 220 kV high voltage lines are 10 m long; the safety distance along high voltage lines 350-500 kV is 15 m.

Regulations on the distance between electrical equipment and residential areas

Considering the safety of electricity and the wind deviation of high-voltage lines caused by strong winds. Furthermore, according to the provisions of the “Rules for the application of the Regulations on the protection of electrical installations”:

The protection zone of overhead power lines must be arranged to ensure the safe operation of overhead power lines constructed and to ensure normal power supply for people's life safety zone. In areas ofdensely populated areas such as factories, mines, towns, markets and villages, the protection zone of overhead power lines is the area inside the two parallel lines formed by the sum of the horizontal distance from the edge of the conductor after the calculated maximum wind deflection and the horizontal safety distance of the building after the wind deflection zone.

Therefore, the minimum distance between the line and the ground, under the condition of maximum calculated sag, should not be less than the following values:

First of all, low voltage lines (380 V) crossing residential areas must not be less than 6 m, low voltage lines (380 V) crossing non-residential areas must not be less than 5 m;

Secondly, medium voltage lines (6-10 KV) passing residential areas are not less than 6.5 m, medium voltage lines (6-10 KV) passing through areas non residential are not less than 5 m;

Third, 35 m; -110KV lines crossing residential areas do not measure less than 7 m, 35-110KV lines crossing non-residential areas do not measure less than 6 m and 35-110KV lines crossing areas with traffic difficulties do not measure less of 5.5 m;< /p>

Fourth, the length of 154-220KV lines passing through residential areas should not be less than 7.5 m, the length of 35-110KV lines passing through non-residential areas should not be less than 7.5 m; must not be less than 6.5 m and the length of 35-110KV lines crossing areas with traffic difficulties must not be less than 5.5 m;

Fifth, the length of 330KV lines passing through residential areas should not be less than 8.5m, i.e. a length of 35m; -110KV lines crossing non-residential areas should not be less than 7.5m, and the length of lines 35-110KV crossing areas with traffic difficulties must not be less than 6.5 m.

Be careful to avoid municipal facilities when buying a house

1. Power plant

Common methods of generating electricity include: thermal power, hydropower, wind power, nuclear power generation, and waste incineration power generation . There are several types, and the most likely to be located near residential areas is the waste-to-energy power plant. Incineration of waste will inevitably produce highly toxic gases and dioxin, an internationally recognized carcinogen. However, if (note if) the power plant uses 3T technology, dioxin emissions will be fundamentally lower than the 0.1 ngTEQ required by European standards. requires that it not cause air pollution. Although he is notThere is currently no evidence that cancer patients near waste incineration power plants are directly linked to power plant emissions, home buyers are recommended to keep a distance of more than 300 meters from them .

2. Wastewater treatment plant

Sewage treatment plants have different types and surrounding environments, as well as their safety distances. Not the same either. Newly constructed sewage treatment plants generally adopt an underground green construction model. When completed, there will be no smell or noise, and they are all built underground. For sewage treatment plants built earlier, I cannot say for sure. We still need to review the inspection records from the Environmental Protection Department. It is recommended, when buying a house, to maintain it in good condition.ns 300 meters from the wastewater treatment plant.

3. Gasoline stations and gas stations

At present, unleaded gasoline has been popularized in gas stations, and the natural air circulation and airflow generated by Vehicle traffic will accelerate the diffusion of oil vapors, which are harmful to residents. There will be no danger for local residents, but the impact of dust and noise from passing vehicles must be taken into account.

Finally, it is recommended not to ignore the surrounding sources of pollution when choosing a house, and to try to keep the field of attention within a radius of approximately 1 km around the property. You can walk around the building in the evening, as factories whose emissions do not meet the standard usually choose to discharge their wastewater at night and smell if there is a pungent or strange odor. You should also pay more attention to quality reporting.air, water and others regularly published by the relevant monitoring agencies. If you encounter suspected sources of pollution that you cannot determine, you can contact the environmental protection department for monitoring and confirmation.

The specific standards and amounts of various land acquisition compensation fees are stipulated in the Land Acquisition Compensation and Resettlement Plan approved by the governments of the city ​​and county in accordance with the law on average annual value of production. the three years preceding the expropriation of the land are determined (the relevant land compensation fees, resettlement assistance compensation standard) will be based on the annual statistical report of the most basic unit approved by the local statistics service and on the unit price approved by the departmental price.

If the compensationLand ations and resettlement subsidies paid according to regulations still fail to maintain the original living standards of farmers who are to be resettled, resettlement subsidies can be increased. The compensation standard for land acquisition is based. According to Article 47 of the Land Management Law, if land is expropriated, compensation will be paid based on the original purpose of the expropriated land.

Remarks:

Wind projects Validity period of the approval document is usually 2 years. According to legal regulations and the requirements of the approval document, the construction of the project must start within the validity period of the approval, otherwise the approval document will automatically expire. Although approval of wind projects mayprinciple to be extended, most projects whose construction has not started after the approval deadline encounter serious problems and are recommended to be abandoned. Everyone in the circle discussed that no old project was successfully acquired in the end.

Do not occupy existing forest lands in Class I Protected Forest Lands, Class II Protected Forest Lands and existing forest lands in Class III Protected Forest Lands or above in Forest Areas national keys determined by the Council of State. , except for provincial investment authorities, except for approved wind power projects, the first-level national public welfare forest land will not be occupied.
