Technical Field

[0002] An overvoltage protector is an advanced protective device that limits lightning overvoltage and operating overvoltage. It is a relatively advanced protective device, mainly used to protect the insulation of electrical equipment such as generators, transformers, switches, busbars, and motors from overvoltage damage. It is equivalent to the high-voltage form of a surge protector and is a partial substitute for a lightning arrester. Its function is equivalent to a lightning arrester, but it is different from traditional lightning arresters. The line-type overvoltage protector is used to protect distribution network (insulation) lines, effectively preventing lightning strikes and line breaks and various overvoltage hazards and tripping. The existing overvoltage protector is complicated to install and requires quick installation. The gap between the insulators also needs to be adjusted during installation. When there is a lightning overvoltage, the gap breaks down first, which can protect the insulator string from lightning damage. Utility Model Content
