Description
Technical field
The utility model is related to arc extinguishing thunder resisting equipment technical field, and specially a kind of compression line span center thunderbolt is dodged
Network arc extinguishing lightning protection device.
Background technology
Transmission line of electricity lightning protection is always the important content of power department Thunder Protection, and lightning strike accident is still influence power network peace
One of full key factor.The existing overvoltage protection design specification regulation the air gap S (in terms of m) of China presses formula：S=
0.012l+1 (m) is calculated, and wherein l is span (unit m).This formula is assuming that Tower Surge Impedance feelings are reflected and do not considered to complete bear
Derive and form under condition, draw to be not in the central phenomenon of lightning conducter span of being struck by lightning.But in actual moving process, thunderbolt is lightning-arrest
The counterattack that line span center is caused causes shielding phenomenon to happen occasionally with thunderbolt wire span center, and probability of happening is big, Yi Zao
Cause flashover on the spot and insulator arc-over into transmission line of electricity generation Lightning Over-voltage and cause transmission line of electricity to trip.In recent years, it is defeated
