Description

Technical Field

[0001] The utility model relates to a power grid device, in particular to a handheld one-key safety measure verification instrument for intelligent substations. Background Art

[0002] Regular maintenance of substations is one of the important measures to ensure the power supply security and reliability of the power system. In order to consider multiple factors such as safety, equipment operation status, and operation efficiency, the safety measure ticket, as an effective means, has been used in the power industry for decades. In traditional substations, secondary circuits and pressure plates are mostly physical devices, and the disconnection status of the circuits is clearly shown through physical disconnection points. According to the principle of electrical breakpoints, operation and maintenance personnel only need to confirm whether these physical disconnection points exist to ensure that the equipment outlets will not malfunction during maintenance, thus maintaining system safety.

[0003] With the continuous progress of power system technology, the wide application of intelligent substations has gradually replaced traditional substations. Intelligent substations have now become an important part of the Chinese power grid. Different from traditional substations, the secondary circuits of intelligent substations are no longer displayed in the form of physical circuits, but transmit secondary information through optical fibers, soft pressure plates, and hard pressure plates. This information is stored in the standard configuration description file (SCD file) and data interaction is carried out through network communication. This design makes it difficult to intuitively present the information of the secondary circuit to operation and maintenance personnel, increasing the difficulty of maintenance management and bringing more potential safety hazards. In actual operation, the maintenance of secondary circuits in intelligent substations faces new challenges. Although the degree of intelligence has increased, many operation and maintenance personnel still rely on traditional operation modes when performing maintenance tasks. They need to manually analyze the on-site equipment operation status and operation methods first, then compile safety measure tickets, then turn on and off the corresponding soft and hard pressure plates on the protection devices one by one, and finally confirm the correctness of each operation. The whole process relies heavily on the technical level and experience of operators, with high manual operation risks and unpredictability. Moreover, it can handle the maintenance of a single secondary device, but for the situation of simultaneously maintaining multiple secondary devices, only relying on the method of manually issuing tickets based on experience, neither safety nor efficiency can be guaranteed. With the virtualization of the secondary circuit information in intelligent substations, the interconnection relationship between secondary devices is more complex and numerous, and it is difficult to isolate devices during the operation and maintenance or fault analysis of secondary devices, thus increasing the operation and maintenance difficulty of operation and maintenance personnel.

[0004] Therefore, it is necessary to introduce more intelligent maintenance means to ensure that the technical potential of intelligent substations is maximally exerted and further improve the safety and operation efficiency of the power system. Content of the Utility Model
