摘要静电放电现象存在于电雷管的整个生命周期,在制造、装配、运输、勤务处理、贮存及使用过程中,电雷管时刻都面临着静电冲击的危险。静电会造成电雷管的意外发火,引起意外燃烧爆炸事故。本文在前人的基础上,从机理上分析了电雷管的静电安全问题,并着重分析了人体静电对电雷管的危害。介绍了电雷管的典型防静电结构和最常用的防静电设计技术,并针对某小型化敏感型电雷管进行防静电设计,从空气隙泄放,使用绝缘环,涂覆导电胶三个方面进行设计和试验验证,认为对小型化敏感性电雷管而言,进行防静设计,涂碳化硅导电胶是可以优先选用的方法。73511

Title Optimization design of detonator in electro-static sensitivity
Abstract
Electro-static discharge is existed in the whole life cycle of electro-detonator, in process of manufacturing, assembling, transporting, servicing process, storaging and employing, electric-detonator is facing the danger of static shock all the time。 Static may cause the accidental ignition of electro-detonator, leading to the accidental combustion explosion。Based on the predecessors, this paper analyses static problem of electro-detonator from the mechanism, especially the harm of human body static to electro-detonator。This paper introduced typical structure of anti-static electro-detonator and most commonly used technology of anti-static,and provided some anti-static design scheme for a sensitive miniaturized electro-detonato,which contained three aspects, adopting air gap discharge static, using insulation ring, coating conductive adhesive。Tested and validated the three anti-static design scheme, the results showed that coating conductive adhesive was the best way for a sensitive miniaturized electro-detonato to prevent static。
