Safety distance of prefabricated substation

Box-type substation is also called prefabricated substation. It is a kind of high-voltage switchgear, distribution transformer and low-voltage power distribution device. It is a factory-prefabricated indoor and outdoor compact power distribution equipment arranged according to a certain wiring plan. It combines the functions of transformer step-down and low-voltage power distribution organically. At the same time, it is installed in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, anti-theft, heat-insulating, fully enclosed, and movable steel structure box. It is especially suitable for urban network construction and transformation. It is a rising one after civil substations. A brand new substation. So what is the safe distance of the box-type substation?

According to the "Safety Regulations" data, the safety distance of each voltage level is: 500kv, 5 meters; 220kv, 3 meters; 110kv, 1.5 meters; 35kv, 1 meter; 10kv, 0.7 meters. As long as this distance is ensured, you will not get an electric shock first. Secondly, with regard to electromagnetic wave radiation, power transmission and distribution are all low frequency of 50HZ, and low frequency electromagnetic waves are released, and high frequency electromagnetic waves are really harmful to the human body. Like the water ripples caused by stones, electromagnetic waves will gradually weaken with the propagation distance. The outdoor box-type substation itself emits low-frequency electromagnetic waves, which are easy to weaken with distance and naturally cause less damage. So as long as you are not close to the outdoor box-type substation or open the door of the box-type substation without authorization, you will not cause any harm to your health.
