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.
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.
Solidarity, be of one heart and one mind, any powerful enemy, any difficulty, we will surrender to.
