The Research of the Insulation Coordination of the Transmission Lines with Parallel Gaps in More Thunderstorm Region

Abstract

Parallel gaps, as a new mode of "channel" type lightning protection, can do it with the sub insulator arc distance to effectively protect the insulator, but the corresponding line tripping rate will be affected because of this; Development method based on the leader in this paper the calculation method of the lightning path, the typical used tower of guangzhou trip rate change after the application of parallel gap situation has carried on the analysis, got a short distance and adopt reasonable reinforced insulation, the trip rates did not rise significantly.
