鲁能奥特(http://www.lnat.com.cn/)不断的吸取别人的经验,教育员工团结向上,教会我们不但要团结和自己意见相同的人,而且要善于团结那些和自己意见不同的人,还要善于团结那些反对自己并且已被实践证明是犯了错误的人。
Luneng otter continue to learn from the experience of others, education staff unity upward, teach us not only to unity and their views of the same person, but also be good at uniting those people who disagree with, but also good at uniting those who oppose themselves and have been proved to be wrong.
       随着计算机及网络通信技术的发展,变电所自动化技术对电气五防闭锁系统的要求进一步提高,传统电气防误五防闭锁方式已不能满足要求,而作为变电所自动化运用发展方向的微机五防系统,在功能上还有待进一步完善和提高。从目前的运行情况来看,程序锁在使用中所暴露的问题是:①某些程序锁功能简单,只能在较简单的接线方式下采用,由于不具备横向闭锁功能,在复杂的接线方式下根本不能采用;②具有较灵活闭锁方式的程序锁虽然能满足复杂的接线,但在闭锁方案中必须设置母线倒排锁,使得操作过程十分复杂;③在大容量的变电站中,隔离开关分合闸采用按钮控制电动机正反转,而程序锁对按钮无法进行程序控制;④程序锁也需要众多的程序钥匙,由于安装不规范、生产工艺及材料差等问题,使程序锁易被氧化锈蚀、发生卡涩,致使一定时间内失去闭锁功能;⑤倒闸操作中,分、合两个位置的精度无法保证;⑥程序锁使用时,必须从头开始,中间不能间断。所以程序锁现在已不采用。
         With the development of computer and network communication technology, automation technology for electrical five anti-lock system requirements to further improve the substation, the traditional electrical anti-misoperation five anti blocking methods can not meet the requirements, as the computer substation automation application development direction of the five prevention system, the function needs to be further perfected and improved. Judging from the present situation, the program lock exposed problems in use are: ① some program lock function is simple, can only be used in the connection mode is simple, because do not have the transverse locking function, simply can not be used in the wiring complex; ② has a flexible locking mode program lock can meet the complex wiring, but must be set bus inverted locked in the locking scheme, the operation process is very complex; in the substation capacity, isolating switch closing the button control motor, and the program lock on button cannot be programmed control; the program lock also need many of the program key, because the problem is not installed specification, production process and material etc., make the program lock is easy to be oxidation corrosion occurs, jam, resulting in a certain time to lose lock function; the switching operation, divided, two position accuracy cannot be guaranteed; the program lock when in use, must start from scratch, not interrupted. So the program lock is not used.
        团结一致,同心同德,任何强大的敌人,任何困难的环境,都会向我们投降。
        Solidarity, be of one heart and one mind, any powerful enemy, any difficulty, we will surrender to.
