摘要/Abstract

摘要： 针对陕西地区配电线路避雷器防雷效果不理想这一现状，提出一种多腔室雷击闪络限制器。该装置防雷性能优异，采用吹弧原理，熄弧能力强。经过试验，确定其串联级数为26级，电极直径8 mm，电极间隙1 mm，主间隙距离取45 mm时能可靠动作。工频湿耐受电压、50%雷电冲击动作电压、雷电冲击伏秒特性以及工频续流遮断能力均满足标准要求。装置在陕西地区典型线路上运行良好，防雷效果优异。

关键词: 防雷装置, 工频续流, 配电线路, 雷击闪络限制器, 防雷性能

Abstract: Based on the operation situation of the lightning arresters commonly used in Shaanxi Province, a lightning arrester with multi-short-gaps is developed, which has excellent ability in extinguishing arc. It is determined through testing that the lightning arrester can act reliably with parameters of 26 in series number, 8 mm in electrode diameter, 1 mm in electrode gap clearance and 45 mm in main gap clearance; and the power frequency wet withstand voltage, the 50% lightning impulse withstand voltage, the volt-second characteristics of lightning impulse and the current cut-down ability all meet the requirements of standard. The newly developed lightning arrester operates well in typical lines in Shaanxi Province with good lightning protection performance.

Key words: lightning protection equipment, continuous current, distribution line, lightning arrester, lightning protection performance
