| Abstract: | Lightning activities are frequent in hilly areas and does great detriment to the safe operation of 35 kV overhead lines.The 35 kV overhead lines in Guangdong is frequently suffered lightning strike.On the basis of collecting extensive materials of the line,this paper analyzes the reason of frequent lightning strike and proposes to use shunt gap as the lightning protection.This paper also analyzes feasibility for the shunt gap measure and designs the structural sizes of shunt gap.Lightning impulse tests are performed to shunt gap test object to find the distance between two balls,calculating the influence on lightning trip-out rate after using shunt gap,and finding that the influence is acceptable. |
