摘要
针对110kV同塔双回线路一回运行、一回停运,检修人员对感应电压和感应电流危害认识不足的问题,以某次感应电致死事故为原型,量化分析了110kV线路典型设计方案下人体触电时承受的感应电压和感应电流。在分析人体电阻以及人体伤害与感应电压、感应电流和持续时间关系基础上,研究了检修人员受感应电伤害风险与线路长度、运行线路潮流的关系。研究成果对于提升现场操作人员的安全意识,减少安全生产事故具有重要意义。
Aiming at the problem that maintenance personnel lack of knowledge about induced voltage and induced current on the non - energized line while another line is energized in 110 kV double - circuit transmission lines, the quantitative analysis of induced voltage and induced current bore by human body when getting an electric shock is carried out based on the typical 110 kV line design. Based on the analysis of human body resistance and the relationship between harms to human body, the induced voltage and induced current and their duration, the relationship between the risk of injury by induced electricity, line length and line flow of energized line is studied. The research results are of great significance to improve the safety conscious-ness of operators and reduce production safety accidents.
