Technical Field

[0001] The present invention relates to the technical field of substations, and in particular to a substation early warning system based on Internet management. Background Art

[0002] Substation is a device used to convert high voltage electricity into low voltage electricity, and is usually used in power systems in cities or industrial areas. Substations are mainly used for the transmission and distribution of electric energy. They can convert electricity from high voltage transmission lines into low voltage and connect it to different power consumption areas. As an important part of the power system, the safe operation of substations is crucial to ensuring the stability and reliability of the entire power grid.

[0003] During the long-term operation of the substation, various faults are prone to occur in the electrical equipment and lines in the substation over time, affecting the safe use of the substation. Therefore, it is necessary to detect the substation to find safety hazards in time;

[0004] However, the current monitoring of substations mainly relies on manual inspections, which is not only time-sensitive, but also difficult to ensure the comprehensiveness and effectiveness of monitoring. It is easy to make mistakes and miss inspections, and it is impossible to monitor safety hazards in time and eliminate them in time. There are limitations, which is not conducive to ensuring the safe and effective operation of substations. With the development of the times and the rise of the Internet, we have provided a new way to solve the above problems.
