摘要：During the operation of the substation, the operation and maintenance personnel in the station need to perform electrical switching operations. In the event of accident, it will often result in personal injury or death, equipment damage or power outages, and even major accidents such as grid collapse, directly affecting the company's social image and economic benefits. The generation and development of the microcomputer "five-prevention" system is to reduce the probability of accidents caused by misoperations, and even to avoid misoperation. It has three main advantages, including a high degree of intelligence, complete functions, and simple operation. Its operation steps have very strict requirements, due to the natural environment, human error, the failure of the anti-misoperations device itself, the "five-prevention" system to go empty, and other factors, causing the five-prevention system to malfunction. In view of the above problems, this program studies the problem of overhaul prevention in this mode, and provides targeted solutions to improve the locking and control functions of substation maintenance operations, increase the safety control of the operating electrical secondary equipment, the safety control of the isolation equipment, the safety control of the maintenance equipment, and the equipment status information comparison, etc. In combination with the business process and system application of the maintenance work, the original anti-misopration safety control system will become a standardized, informational, Platform-based maintenance control system throughout the whole process of the maintenance work.
