How far should the agricultural transformer be from the residential building

According to the regulations of the Ministry of Construction of the People's Republic of China (GB50053 94), the distance between the outer profile of the transformer and the outer wall of the building should be greater than or equal to 5m.

Because electromagnetic radiation is aimed at microwaves with very small wavelengths, but the frequency of the transmission line is 50 Hz, and the electromagnetic wave is up to 6,000 kilometers, even if it is an ultra-high voltage line of 500 kV, it will not produce a strong magnetic field. Otherwise, the energy loss through radiation would be astronomical. In addition, the test data showed that the magnetic field level of the transmission line from 5 meters to 10 meters did not exceed 10 microtesla (the unit of intensity).

Only one turned on hair dryer produces one-seventh of the magnetic field.

1. One-fifth of the electric blanket. In 1995, the WHO also launched the "EMF" 10-year international research program to study low-frequency electromagnetism such as high-voltage lines, but so far it has not been found to have any definite hazards. Electromagnetic experts say the result does not mean that there is some kind of unknowable hazard in the magnetic field of high-voltage wires, but rather that there is "no harm".

The limits on electric and magnetic fields in China are stricter than those in developed countries such as the United Kingdom and Germany. In the United States, for example, in 1992 the limit was expanded from 100 microtesla to 900 microtesla. The domestic limit has always been no higher than 100 microtesla.

So, there's no need to worry too much about electromagnetism at all.

Summary. Rural transformers are generally semi-open-air small substations, with a general voltage of less than 10,000 volts, and at least 5 meters away from residential buildings is a safe range.

If it is a rural area to change the line, the compensation for cutting down trees will be paid by the village or the power station.

Article 10: Power Line Protection Zone: (1) Overhead Power Line Protection Zone:

The area in which the wire edge extends horizontally to the outside and is perpendicular to the ground to form two parallel planes, and the extension distance of the side line at all levels of voltage wire refers to the general area is as follows: 1-10 kV - 5 m 35-110 kV - 10 m 154-330 kV - 15 m 500 kV - 20 m In densely populated areas such as factories and mines, towns, etc., the area of the overhead power line protection zone can be slightly smaller than the above provisions. However, the distance of the extension of the edge of the voltage wire at all levels should not be less than the sum of the horizontal distance of the wire edge after the maximum calculated sag and the maximum calculated wind deviation and the safe distance from the building after the wind deviation.

How far away should the large ones be.

China Southern Power Grid. Hello, the distance between the large outdoor oil-immersed transformer and the house should be kept at least 10 meters.

Thank you. Hello, you're welcome to contact me at any time if you have any questions.

Is there a blessing to be by the house?

Hello, not much radiation.

There will be an electromagnetic field around the transformer, because the electric field itself is not harmful, and the relative character has an effect on electromagnetic radiation, and the impact of a transformer on the human body is not as large as the electromagnetic radiation generated by the electrical appliances in your imitation home. Regardless of whether it is a high volt or a low volt voltage swing residue, the power frequency electromagnetic field strength generated is very low, accounting for only 1 10 or less of the limit that may affect the human body. The maximum civil transformer is 10,000 volts.

Only high-frequency electromagnetic radiation can cause harm to human health, and the 50 Hz power frequency electromagnetic field of power facilities is not harmful to human health. So don't worry.

Hope mine is helpful to you, feel free to contact me if you have any other questions.

Summary. The construction of rural transformers should be 3 meters away from private houses. According to the Manual of Electrical Design of Electric Power Engineering, the distance between 10 kV electrical equipment and the building is at least 3 meters. Therefore, the transformer is 3 meters away from the house and meets the safety standards.

35-110 kV - 10 m 154-330 kV - 15 m 500 kV - 20 m.

Summary. Hello, the construction of rural transformers should be 3 meters away from private houses, according to the "Electric Power Engineering Electrical Design Manual", 10 thousand volt electrical equipment from the building is at least 3 meters. Therefore, the transformer is 3 meters away from the house and meets the safety standards.

Dear, hello shed trembling talk, your hole in this question by me to help you answer, is answering for you, please wait a while, don't be too anxious, I hope my chain touch answer can help you, solve your troubles, I wish you a happy life, good health.

Hello, the construction of transformer in Nongsheng Chain Village should be 3 meters away from the house, according to the provisions of the "Electric Power Engineering Electrical Design Manual", the distance between the electrical equipment of 10,000 banquet molds and the building is at least 3 meters. Therefore, the transformer is 3 meters away from the house and meets the safety standards.

In rural areas and near residential buildings, transformers equipped with a voltage level of 10 thousand volts are generally equipped. According to the standard, the transformer is safe beyond the meter of the house, but from the above case, the actual distance is 4 meters, which is greater than the standard safe distance. So, when you have doubts:

Is there a transformer downstairs in the community too close?You might as well estimate it based on the above criteria. In fact, in the actual construction and installation process of power facilities, the distance from the power equipment to the building will only be longer than the specified standard safety distance, please rest assured!

Of course, if you have electrical equipment first, and then build a house in the surrounding area, please also pay attention to the safety distance when building a house!

The safety distance of the transformer from the residential area is greater than three meters, in fact, it is installed as much as possible more than ten meters, if the distance is insufficient or the high-altitude feelings are complicated, it can be designed as an indoor transformer.
