Defect analysis of traditional lightning arrester and fuse split type and a new lightning protection fuse combination device

Bin Liu, Cunjin Wei, Feng Zhao, Kaixuan Zhai, Linsheng Ma

Abstract

The traditional lightning arrester and fuse are installed separately with double cross arms, which has high installation material cost, long working time at height, and too many installation nodes are not conducive to later maintenance. The lightning protection fuse combination device shares an insulating base between the lightning arrester and the fuse, saving 1/2 of the material cost and installation time. A new type of thermal loss of excitation disconnector is built in the arrester part of the combined device, which can safely separate the aging arrester from operation, so that the arrester can be maintenance-free and live replacement.
