Copper-plated round wire manufacturers explain lightning protection measures:
According to different protection objects, appropriate safety protection measures should be taken for direct lightning strikes, inductive lightning, and lightning wave intrusion.
(1) Protection against direct lightning: mainly to install lightning protection pins, lightning protection lines, lightning protection nets, lightning protection belts, lightning arresters and other protective measures. It is required that the grounding resistance does not exceed 10 ohms. It is strictly forbidden to erect communication lines, broadcasting lines or other electrical lines on structures equipped with lightning rods and lightning protection lines; since the lightning receptors, down conductors and grounding devices subjected to lightning strikes exhibit high impact voltage, Spark discharge (lightning strike) may occur with adjacent conductors, so there should be sufficient safety distance.
(2) Protection against inductive lightning strikes: Inductive lightning strikes, also known as lightning induction, refer to the fact that the metal conductor near the space thundercloud is charged by the action of electrostatic induction. When the lightning strike occurs, the induced overvoltage on the metal conductor is discharged to the earth. The phenomenon of lightning strikes formed. The precautionary measures are mainly to properly ground the metal roof, metal equipment in the building, all pipelines, structural steel bars, etc., to eliminate the impact of induced lightning strikes.
(3) Protection against lightning wave intrusion: refers to the high-voltage shock wave of direct lightning strike or inductive lightning intrusion along overhead lines or metal pipelines, which accounts for a considerable proportion of lightning hazards. The main protection methods are: adding a tubular or valve type arrester to the overhead line, and grounding the metal pipe at multiple points.
(4) Protection of ball mines: At present, due to the mechanism of the occurrence of ball mines, there is no clear protection method. Generally, the method of lightning arrester or full shielding is used for protection.
