Directly affect the reliability of distribution system power supply.Therefore, it is necessary to the lightning surges of centering press-fitting network system, and protection to be taken to arrange
It applies.
Series gap arrester is installed on overhead transmission line road, can be struck by lightning in route or insulator chain flashover
When effectively release overvoltage and the calcination of protecting insulator chain from electrical discharge arc.Normal tape arrester with series gaps can have
The overvoltage of effect attracted on route, punctures the air gap, and overvoltage is imported the earth.But this arrester is deposited and not caned oneself
The dynamic electric arc and series gap of extinguishing is apart from unfixed problem.
When discharging gap and can not automatic distinguishing because breakdown the air gap caused by power frequency continued flow electric arc, only and automatically
Reclosing device is used cooperatively, and could obtain preferable lightning protection effect.But due to needing to wait breaker actuation, cause to go here and there
The arc extinction time is longer on connection gap, and the overvoltage on route is released to the earth every time, may all make fitting by electric arc
It burns, conducting wire can be even blown when situation is serious.
