It is understood that the current state regulations for the construction of power supply equipment above 100kV must pass the administrative permit of the environmental protection department. The environmental protection inspection indicators mainly include the electric field, magnetic field, radio interference and noise.
The power supply facilities installed in residential areas must be approved by the State Environmental Protection Administration and must meet these standards: the power frequency electric field strength should not exceed 4 kV / m, and the magnetic induction strength should not exceed 0.1 milliTesla. In terms of radio interference, 110KV projects do not exceed 53 dB, and 500KV projects do not exceed 55 dB. The impact of noise does not exceed 55 decibels during the day and 45 decibels at night. As long as these indicators meet the standards, there is no strict requirement on the distance between related equipment and buildings in terms of environmental protection.
However, according to the Ministry of Environmental Protection, China currently has certain requirements for the distance between equipment and buildings. For example, the general 10kv-35kv substation requires that the distance from the residential building to the front is more than 12 meters, and the side is more than 8 meters. For substation construction above 35KV, it is required that the distance from the front of the residential building is more than 15m, and the distance from the side is more than 12m. Box-type substations are more than 5 meters from residential buildings.
