摘要
为防止雷电火灾,分析了油气区雷电灾害的机理以及常用的防护措施;测量统计了避雷针的电晕电流及避雷针保护区内外地面电场的变化情况,总结出该地区的雷电形成、发展变化规律;研究了地面电场、电晕电流与雷电活动的关系,初步建立雷电多级报警系统,最后确定报警阈值,其中解除雷电报警应低于0.5kV/m。
This paper presents the mechanism of lighting disturbance and the general protection for the lighting fire.The properties of lighting forming and changing are obtained by measuring corona current through the lighting rod and ground electric field inside and out of protection area.The different lightingalarm threshold values are given on the basis of the relations of lighting movements to ground electric field and corona current,and PC based monitoring alarm system is developed.
