      一滴水飘不起纸片,大海上能航行轮船和军舰;一棵孤树不顶用,一片树林挡狂风……这就是团队精神重要性力量的直观表现,这也是我所理解的团队精神,也是团队精神重要之所在。
       Can not slip a drop of water, the ocean sailing ships and warships; A solitary tree ever working, a piece of wood block wind... This is the team spirit importance intuitive performance of power, this is what I understand team spirit and team spirit also important.
        五防闭锁用微机存储标准票系统,微机可能调出错误的操作票,而使用微机防误闭锁装置填写的倒闸操作票是通过操作人员在微机屏幕系统图上逐项点击操作后生成的,微机内的系统图始终与现场实际相符,实际上就相当于操作人用大脑指挥微机填写操作票,同时它还有五防功能做为防误保护。 电气闭锁与微机防误闭锁相联合诚然微机防误闭锁解决了电气闭锁的两大缺点,其防误成果也不错,然而一旦微机防误发生故障时,完全依靠微机防误的隔离开关就不了防误闭锁功能,这就是微机防误的一大弊病。解决该问题的办法就是将电气闭锁和微机防误相结合,对隔离开关进行防误闭锁。这种闭锁方法即使在防误微机故障时,电气闭锁仍起作用,防误操作方面的可靠性就相当高了。但这种方法的缺陷和电气闭锁的毛病一样,就是当电气闭锁回路接点接触不良引起故障时,远方解除闭锁无奈实现
        Use computer storage standard ticket system, the microcomputer may bring up the wrong operation, and microcomputer using lock fill out pour brake operation is by operating personnel in computer screen system item by item, click on the graph generated after operation, microcomputer in the system diagram is always consistent with actual, in fact is the equivalent of people in the brain command microcomputer operation ticket, at the same time it also has five functions as a protection against false proof. Microcomputer electric locking and blocking associated microcomputer admittedly atresia solves the electric lock two big shortcomings, its anti false results is good also, microcomputer, however once a failure occurs, the microcomputer depend entirely on the isolation switch is not the function of anti false atresia, microcomputer that is a big drawback. Solution to the problem is the combined microcomputer electric locking and isolating switch for anti lock by mistake. This method even in atresia error protected computer failure, electrical lockout still play a role, prevent wrong operation in terms of reliability was quite high. But the defect of this method, and problems with electric lock, is when the electric locking circuit contact caused by poor contact failure, distant remove locking implementation
       电气闭锁在无人值班站的运行操作方面可靠性不高。由于该闭锁原理是在隔离开关(刀闸)的电动操作回路中串联了若干帮助接点,当其中某一个接点接触不良就会引起全体回路故障,使正常操作无法实现,特别在变电站无人值班时,要进行远方解锁是无法实现的。另外,螺杆泵,当电动操作回路的其它设备有故障时,巡检职员要进行就地手动操作时就不闭锁限度了,所以电气闭锁只在电动操作时起作用,其闭锁牢靠性也不高。
       Electric locking in the unattended station operation reliability is not high. Breaker is due to the blocking principle in isolating switch (the) series electric circuits of several help contact, when a bad contact contact will cause the circuit failure, make normal operation cannot be achieved, especially in unattended substation, to unlock is not far away. Additionally, screw pump, when the electric circuit operation of other equipment is faulty, inspection staff for local manual operation is not locking limit, so the electric lock only works when electric operation, its blocking solid sex is not high also.
