Safe distance refers to a certain safe distance between charged body and the ground, between charged body and other facilities and equipment, and between charged body and charged body.

The purpose of setting a safe distance is to prevent the human body from touching or approaching the charged body and causing electric shock accidents; Prevent vehicles or other objects from colliding or getting too close to charged objects to cause accidents; Prevent electrical short circuit accidents, overvoltage discharge and fire accidents; Simple operation.

Extended data:

The minimum distance between people and charged bodies, charged bodies and charged bodies, charged bodies and the ground (water surface), charged bodies and other facilities is also called safe clear distance and safe spacing.

The safety distance shall ensure that flashover discharge does not occur under the action of various possible maximum working voltage or overvoltage, and also ensure the absolute safety of the staff during the inspection, operation, maintenance and overhaul of electrical equipment.

Various safety distances are stipulated in relevant laws and regulations promulgated by the state. When the actual distance is greater than the safe distance, the human body and equipment are safe.

Safe distance is not only used to prevent human body from touching or getting too close to charged bodies and getting an electric shock, but also used to prevent vehicles from colliding with other objects or getting too close to charged bodies, causing discharge and short circuit between charged bodies and causing fire and electrical accidents. Safety distance is divided into line safety distance, power transformation and distribution equipment safety distance and maintenance safety distance.
