       任何事物都是依据其自身的客观规律循序渐进地发展的,技术的发展一般遵循需求提高,再需求—再提高的规律,需求不止发展也就永远不会停滞。微机防误操作系统技术的发展也不例外。所谓“离线” 操作模式,是指在操作过程中电脑钥匙与主控系统之间没有通讯联系,此种模式下电脑钥匙只能顺序执行预存的操作票。由于离线模式而导致微机防误装置失去防护效果,发生误操作事故的例子很多,比如某电厂对一条热备用线路转停电检修操作时,在运行人员前往现场操作的过程中由于二次的原因断路器重合,而运行人员未能及时接到通知,仍然用电脑钥匙按预存的操作票打开线路侧刀闸的防误锁具,然后拉开刀闸,造成一起带负荷拉刀闸事故。某变电站执行某线路停电检修操作时,运行人员持电脑钥匙接通电气锁回路并断开断路器,然后用电脑钥匙打开线路侧刀闸的防误锁具,拉开刀闸,却造成一起带负荷拉刀闸事故,事后分析原因是由于断路器的触头没有完全脱开造成的。
       Everything is according to its own objective law step by step development, the development of the technology generally follow the demand increase, demand again - to improve and demand more than the development also will never halt. Microcomputer five anti blocking the development of technology is no exception. So-called "offline" operation mode "refers to a computer in the process of operation keys and there is no communication between main control system, this kind of mode computer keys can only be executed sequentially deposited operation ticket. Due to offline mode lose protection, computerized anti-malfunction device misoperation accident of many examples, such as a power plant to turn a hot standby line outage maintenance operation, in the process of operation personnel to site operation due to the cause of the secondary circuit breaker reclosing, the operation personnel failed to received notice, still use computer keys by persisting in the operation ticket open circuit breaker side to prevent false lock, then away breaker, breaker belt load pull the accident cause. A substation performs a line outage overhaul operation, operators of a computer key through to electric lock loop and disconnect circuit breaker, breaker then used computer keys to open the line side to prevent false lock, open knife switches, a breaker belt load pull the accident is caused, after analysis of the reason is caused by circuit breaker contact not fully release.
