摘要
Abstract
As a new channelizing type protective manner, the parallel protective gap can provide effective protection for insulator string to achieve more reliable reclosing. The current researches on the parallel protective gap in China are focused on moving characteristic of arc and shape of the gap, but few researches are concerned with the characteristics of the gap and the relationship between arc on the gap and insulator. The authors conducted a number of tests to investigate protective property of the gap to insulator , and suggested that the distance between two electrodes of the gap be large than 90% of insulator string's structural height, and the distance between the gap and insulator string be sufficient for achieving effective anti-lightning protection of insulator string.关键词
