In order to effectively prevent the misoperation caused by the electrical devices of the personal and major equipment accident, as early as in the last century in the early 90, the State Power Authority proposed electrical equipment "five protection" requirements and the unlocking key management system, and to form regulations provisions of the electrical misoperation of management, operation, design and use of the principle of. According to this stipulation, the design of anti misoperation device should follow the principle is: where possible due to high voltage electrical equipment malfunction, shall be installed security error device and error proof electric locking of the corresponding loop. The past can not be achieved can be achieved or anti error function is very difficult to achieve, can be said to be a misoperation prevention technology of electrical equipment of the latest technology and pentium. But the microcomputer five protection system vulnerabilities and its fatal weakness is that, the anti function to manipulate the logic as the core, for the error touch no and vote manipulation (mainly the inspection staff) are likely to stop.
The unlocking key management system for you to solve the problem of electric anti maloperation, Shandong Luneng technology limited company is the most reliable option!
