Abstract
A lightning protection gap with a discharge counter comprises a gap high-voltage electrode, a gap grounding electrode, the discharge counter, a discharge counter driving device, connecting hardware, fixing parts and other accessories. The lightning protection gap with the discharge counter is designed according to frequent lightning stroke discharge accidents on power transmission lines. A lightning stroke discharge passage is formed between the gap high-voltage electrode and the gap grounding electrode, lightning stroke flashes over along the gap, transfers and dredges a power frequency electric arc root to be apart from an insulator end, an insulator and the power transmission line are not damaged, and reclosing of a switch can be successful, so that flashover of the lightning stroke becomes an instantaneous fault and normal power supply of a power grid is ensured. The discharge counter driving device on the gap high-voltage electrode or the gap grounding electrode drives the discharge counter connected with the discharge counter driving device to record lightning stroke discharge times, and accordingly lightning stroke discharge cases on the line are monitored. The lightning protection gap with the discharge counter can not only effectively solve the problem of lightning stroke discharge on the power transmission lines, but also monitor discharge times, and is practical and economical.
