Electric power knowledge Substation safety knowledge Electric power knowledge In recent years, urban electricity consumption has continued to increase significantly. However, according to power supply requirements, a large substation can only cover about 1 to 20 square kilometers (equivalent to a power supply range of 0.56 km to 3 km). Therefore, with the development of the city, the improvement of power supply reliability and power quality requirements, the newly built substation can only transmit power to the nearby residents' homes and meet the residents' electricity needs if they enter the residential area. Since most of the substations are built in residential areas, many residents have asked whether the magnetic field of the substation will radiate to the human body.
The urban substation can be an indoor substation. Since the electromagnetic field has been greatly shielded by the wall, the electromagnetic field outside the indoor substation is very small. Adopt SF6 gas-insulated fully enclosed electrical (GIS) equipment. Since GIS uses an insulating medium between high-voltage equipment, and because its exterior is sealed by metal, it is like a protective cover for high-voltage equipment, which effectively controls the electromagnetic field intensity generated by high-voltage equipment.
The double-circuit or multi-circuit erection technology on the same tower is beneficial to reduce the impact of transmission lines on the environment. The substation is equipped with various sensitive and fast safety automatic protection devices, which can instantly remove the fault, ensure the safety of the power grid, and will not affect the surrounding of the substation.
