出了事故,如何分析研究,如何总结经验教训,站在不同角度,追溯不同深度,得出的结论就会相去甚远,付出了“学费”而获得的“效益”也就相差悬殊。这里分析两起事故并略作评价。1 带地线合闸保护线成烧人线1.1 事故经过:1994年4月6日下午3时许,某厂671变电站。运行值班员接班后,312油开关大修负责人提出申请要结束检修工作票,赶上4点的下班车离厂而值班长临时提出要试合一下312油开关上方的母线侧3121刀闸,看看该刀闸贴合情况。于是,值班长在没有拆开312油开关与3121刀闸之间的接地保护线的情况下,擅自摘下了3121刀闸操作把柄上的“已接地”警告牌和挂锁,取下闭锁插销,进行了3121刀闸的合闸操作。只听“轰”的一声响,强烈的弧光迎面扑向蹲在312油开关前的大修负责人和实习值班员,二人当即被弧光灼伤。1.2 原因分析:1.2.1 违背了《工作票制度》中“若扩大工作任务,必须由工作负责人通过工作许可人,在工作票上增填工作项目”之规章,临时轻易增加工作内容,擅自操作,违反基本原则错误地带地线合3121刀
The accident, how to analyze the research, how to summarize the experience and lessons, from different perspectives, tracing different depths, the conclusions will be far cry from the “tuition” and obtain the “benefits” will be the difference Disparities. Analyze two accidents here and comment slightly. 1 with the ground to close the protection line into a singer 1.1 Accident after: April 6, 1994 at 3 pm, a plant 671 substation. After the shift attendant on duty, 312 oil switch overhaul responsible person to apply for an overhaul work ticket to catch the 4 o’clock off the bus and the squadron temporarily proposed to test together 312 oil switch above the bus side 3121 knife gate, see Look at the knife fit situation. Thus, the squad leader removed the “ground” warning pad and the padlock on the 3121 knife gate handle and removed the lock without disconnecting the ground protection cable between the 312 oil switch and the 3121 blade Latches, 3121 knife gate closing operation. Just listen to the sound of “boom”, a strong arc toward the squatting 312 oil switch before the overhaul charge and internship attendant, two were immediately burned by the arc. 1.2 Analysis of reasons: 1.2.1 violates the “work ticket system” in the “work to expand the task, the work director must work through the work permit, work on the work ticket to fill in the” rules, temporary and easily increase the work content , Unauthorized operation, in violation of the basic principles of error with the ground wire together 3121 knife
