Is it harmful to have a substation next to a building?

First, the distance of 200 meters is no problem, but tell the child not to play nearby.

Clause. 2. The radiation of the substation belongs to the power frequency electromagnetic radiation of very low frequency.

There is no scientific evidence to prove that the power frequency electromagnetic fields generated by power supply lines and substation equipment are harmful to the human body. What is harmful to humans is ionizing radiation.

Clause. 3. Although electromagnetic radiation is not too harmful, it is necessary to make relevant provisions on the four major contents of electric field, magnetic field, radio interference and noise.

Clause. Fourth, China currently has certain requirements for the distance between substations and buildings. For example, the general 10kv-35kv substation requires the front to be more than 12 meters away from the residential house and the side to be more than 8 meters; The construction of substations above 35kV requires that the front side is more than 15 meters away from the residential house and the side is more than 12 meters; Box-type substation.

More than 5 meters away from residential houses.

No.

The first is the problem of noise, the transformer will emit humming low-frequency noise when it is running, and the sound will be made when large vehicles enter and exit when the equipment is overhauled, followed by the problem of light pollution, for the sake of safety, the lights need to be turned on 24 hours a day in the substation, similar to the light source of the searchlight, if the place of residence is close to the substation, during the night, this light may affect sleep, and it is best to choose thickened curtains for the windows on the side facing the substation.

The substation is infrastructure, if it has been built, it will not be moved, and it will continue to expand and upgrade, so what we can do is to pay attention to whether the distance between it and the real estate is safe enough, and it is required to be more than 15 meters away from the front of the residential house and more than 12 meters from the side.

Summary. Hello, it is a pleasure to serve you. Theoretically speaking, there is a certain harm, but in real life there is not much harm, because you live indoors, and the voltage is outside, and there is a wall to separate, is it harmful that the substation is next to the building?

You're just keeping your eyes peeled and glad to serve you. Theoretically speaking, there is a certain harm, but in real life there is not much harm, because you live indoors, and the voltage is outside, and there is a wall to separate, the radiation of the substation belongs to the extremely low frequency of power frequency electromagnetic radiation. There is no scientific evidence to prove that the power frequency caused by power supply lines and substation equipment is harmful to the human body.

At present, China has certain requirements for the distance between the substation and the building. For example, the general 10kv-35kv substation requires the front to be more than 12 meters away from the resident's state, and the side is more than 8 meters away; The construction of substations above 35kV requires that the front side is more than 15 meters away from the residential house and the side is more than 12 meters; The box-type transformer is more than 5 meters away from residential houses.

There is a substation next to the building at home, will this be harmful?

The common frequency of power equipment in 220kV and 110kV substations is 50 Hz. It produces a very low frequency electromagnetic field, which cannot transmit energy in space in the form of electromagnetic waves, so the actual impact of the substation on the surrounding area is mainly based on electromagnetic induction effect, rather than electromagnetic radiation.

In fact, electromagnetic induction is something we experience personally every winter. For example, the static electricity generated when taking off sweaters in a dry environment, and the energy of electromagnetic induction in the substation is small, so its impact is negligible.

But there are still some hazards associated with living near substations. The first is the issue of lighting, for safety reasons, the substation is on 24 hours a day, and the surrounding residents may be affected by it.

The second is the problem of noise, the sound of transformers running, the sound of large machinery and vehicles entering and leaving, and the imperfect noise reduction materials of substations, many residents may be overwhelmed. In this regard, there are some institutions that are developing some noise reduction materials and possibilities.

There are also reasons for operational safety, accidents may occur in high-load machines, but accidents will be effectively suppressed due to the open ground. If you live around the substation, you can report any abnormal situation to the relevant departments as soon as possible.

At present, the state stipulates that the construction of power supply facilities above 100kV must pass the administrative license of the environmental protection department. Among them, the environmental protection inspection indicators mainly include electric field, magnetic field, radio interference and noise.

The power supply facilities set up in residential areas must meet these standards in order to pass the environmental protection administrative license: the power frequency electric field strength does not exceed 4,000 volt meters; The intensity of magnetic induction does not exceed 0 1 millitesla; In terms of radio interference, the 110kV project does not exceed 53 decibels, and the 500kV project does not exceed 55 decibels; The noise impact should not exceed 55 decibels during the day and 45 decibels at night.

As long as these indicators meet the standards, there are no strict requirements for the distance between the relevant equipment and the building in terms of environmental protection.

However, according to the environmental protection department, China currently has certain requirements for the distance between equipment and buildings. For example, the general 10kv-35kv substation requires the front to be more than 12 meters away from the residential house and the side to be more than 8 meters; The construction of substations above 35kV requires that the front side is more than 15 meters away from the residential house and the side is more than 12 meters; The box-type substation is more than 5 meters away from the residential house.

There is danger. The substation is a place where the voltage is extremely high, so if the family building is next to the substation, there is a risk of electric shock on a rainy day.

If there is a leak, it can be dangerous, especially if there is a heavy rainfall, and the place is quite unsafe. If you can, don't buy this house, and if you do, ask the property if you can coordinate it.

Hello, how many units are you on the first floor? Is the substation box in the middle of the building? Or both? Thank you.

It should be a box-type substation that gives electricity to your residential complex, and there is no problem.

There is a safe distance to keep a distance and the harm is minimal.

It's not very dangerous, just a little bit of radiation.

The substation has no impact on the residence. Because the substation is a power-frequency electromagnetic field, there is no electromagnetic radiation, even if it is higher than 500 kV around the power transmission and transformation equipment, only extremely low-frequency electromagnetic fields are generated, not electromagnetic radiation. Know.

Harm to people in substations:

1. It has a great impact on children and teenagers, and has little impact on adults, because children are in the growth period, and all aspects of physiology are immature. Therefore, friends with children at home should avoid letting children near the substation while maintaining the above safe distance.

2. Regulations on radiation management of substations.

According to the national measures for the management of electromagnetic radiation, more than 100 thousand volts are electromagnetic strong radiation projects, and Article 20 stipulates that in which section of the area where large-scale electromagnetic radiation equipment or high-frequency equipment is used is concentrated, according to the requirements of environmental protection and urban planning, no sensitive buildings such as residential houses and kindergartens shall be built in the planning restriction area. <>
