摘　　要：据欧美国家每年对电气事故的统计,电弧事故占70%,这其中造成永久伤害20%以上。成千上万的工作人员面临着电弧事故的潜在危害,可能引起严重甚至致命的后果,并且由于对此危害的疏忽而导致2度、3度烧伤事故正在不断增加。近年来,我国对电弧事故造成的人员伤害、经济损失、社会影响越来越来重视,加快弧闪风险评估工作的执行,加大防护装备的投入,正在逐步推进安全管控的落实。文章阐述了弧闪评估的意义和必要性,对弧闪的成因及危害和分析计算方法进行了介绍,并对预防方法进行讨论,增强电气作业人员的安全意识,进而提升电气操作的安全度。According to the annual statistics of electrical accidents in European and American countries,electric arc accidents account for 70%,of which more than 20%of permanent injuries are caused.Thousands of workers are faced with the potential hazards of arc accidents,which may cause serious or even fatal consequences,and the number of second and third degree burn accidents is increasing due to the negligence of this hazard.In recent years,more and more attention has been paid to the personal injury,economic loss and social impact caused by arc accidents in China.The implementation of arc flashover risk assessment has been accelerated,the investment in protective equipment has been increased,and the implementation of safety control has been gradually promoted.This paper expounds the significance and necessity of arc flashover assessment,introduces the causes and hazards of arc flashover and the analysis and calculation methods,and discusses the prevention methods,so as to enhance the safety awareness of electrical operators and improve the safety degree of electrical operation.
