变电站雷击的来源有：一是对变电所设备的直接雷击；二是架空线路雷电感应过

The sources of lightning strikes in substations are: first, direct lightning strikes to substation equipment; second, lightning waves caused by lightning induced overvoltage and direct lightning strike overvoltage on overhead lines invading substations along the line to prevent direct lightning strikes. The main equipment to prevent direct lightning strikes are lightning rods and lightning conductors; second, lightning waves invade electrical equipment and the main equipment inside buildings along the route are lightning arresters, etc. There are single, multiple, equal height, and unequal height arresters; third, valve arresters and metal Oxide arrester.

The sources of substation lightning strikes are: First, the direct lightning strike of the substation equipment, and second, the lightning induction voltage and direct lightning strike over voltage formed by the lightning wave along the way to invade the substation, to prevent direct lightning strikes. The main equipment to prevent direct lightning strikes is lightning rod and lightning line, the second is lightning waves intrusion into electrical equipment and the main equipment inside buildings along the line is lightning protection, there are single, many, equal high, not equal high lightning protection, third is valve lightning and metal oxide lightning protection.

The sources of lightning stroke in substation include: first, direct lightning stroke on substation equipment; second, lightning wave formed by lightning induced overvoltage and direct lightning overvoltage of overhead line intrudes into substation along the line to prevent direct lightning stroke. The main equipment to prevent direct lightning stroke is lightning rod and lightning wire; the second is lightning wave intrusion into electrical equipment and the main equipment inside buildings along the line is lightning arrester, including single, multiple, equal and unequal height lightning arresters; the third is valve type lightning arrester and metal oxide lightning arrester.<br>
