Transformer safety distance Recently in some forums to see everyone in the discussion of these topics, the answer is inconsistent, which caused some people and some of the transformer and the contact with the panic, in fact, we do not panic, today Xiaobian to give you Explain, let everyone take a look!
The safety of the power facilities are generally in order to protect the normal operation of the facilities, so as long as a slight distance can be. Electric power facilities construction planning is in strict accordance with the provisions of the safety distance of the building, so it is safe.
For the protection of the normal operation of the electric power facilities, Article 5 of the Regulations on the Implementation of the Regulations on the Protection of Electric Power Facilities stipulates that the overhead power supply protection zones are necessary to ensure the safe operation of the built-in overhead power lines and to ensure the normal supply of people's lives area. In the densely populated areas such as factories, towns, towns, towns and villages, the overhead power line protection area is the distance between the horizontal distance and the horizontal safety distance of the building after the maximum deviation from the wind area. Voltage level of the wire at all levels in the calculation of the maximum wind deflection of the conductor, the distance from the building safe distance is as follows:
1 kilovolt below 1.0 meters
1-10 kV 1.5 meters
35 kV 3.0 meters
66-110 kV 4.0 meters
154-220 kV 5.0 meters
330 kV 6.0 meters
500 kV 8.5 meters
Electric power facilities construction planning is in strict accordance with the provisions of the safety distance of the building, so it is safe.
In fact, the very low frequency electric field and magnetic field generated by the transformer are in the form of "field", do not form radiation at all, can not radiate energy to the outside, the frequency field, the magnetic field and the high frequency electromagnetic radiation biological mechanism is different Frequency electromagnetic field as the form of electromagnetic waves to form a limited amount of electromagnetic energy radiation or the formation of in vivo capacity absorption, electromagnetic radiation is usually carried out through the antenna outward, and power facilities in the surrounding environment is generated by the power frequency field and the frequency magnetic field, the frequency only 50 Hz, a wavelength of 6000 km, can not be induced in its wavelength range of an orthogonal electric field to form an effective electromagnetic energy radiation
Distance transformer one meter away from the electromagnetic field strength has been very weak, and its own sound fire, explosion, lightning protection and other measures, so do not worry about the transformer location and distance problems, transformer location is mainly due to power supply considerations.
The general safety distance refers to the live or electric wire, according to the relevant provisions of the building and the power line safety distance is as follows:
1, vertical distance: power line voltage level 1kV the following: 2.5 meters: power line voltage level 1-10kV: 3 meters: power line voltage rating 35kV: 4 meters: power line voltage level 60-110kV: 5 meters: power line voltage level 154-220kV: 6 Meter: power line voltage level 330kV: 7 meters
2, the horizontal distance: power line voltage level 1kV the following: 1 meter: power line voltage level 1-10kV: 1.5 meters: power line voltage rating 35kV: 3 meters: power line voltage level 60-110kV: 4 meters: power line voltage level 154-220kV: 5 Meter: power line voltage level 300kV: 6 meters: power line voltage level 500kV: 8 meters. The above provisions are the minimum distance requirement to ensure that the distance from the discharge accident does not occur. In addition, you should also consider the safety distance of electromagnetic radiation, but the safety distance of electromagnetic radiation, there is no corresponding provisions.
