Research on intelligent GIS on-line status monitoring

With the development of the work that “constructing strong intelligent power grid”, intelligent substation system become into the main develop direction. This paper mainly takes research on the on-line monitoring technology about GIS breaker mechanical properties, partial discharge and SF6 gas pressure. By analyzing various on-line monitoring technologies and contrasting the advantages and disadvantages of them, the paper summarize the monitoring technology suitable for GIS equipment and put forward the viewpoint that the integrated design of the traditional high voltage switch equipment and intelligent elements should give first place to the primary equipment. This paper proposes the monitoring technology suitable for GIS based on keeping the primary equipment safe and reliable. The research would provide reference and basis for the subsequent development of intelligent GIS on-line monitoring system.
