Abstract:

Traditional ring main unit is not intelligent, lack of equipment operation status information and low operation as well as maintenance efficiency. In order to solve these problems, a new generation of intensive intelligent ring main unit for intelligent operation and maintenance is studied. The intelligent construction design scheme of ring main unit is formed. Specifically, the SF₆ gas insulation ring main unit is divided into a sensing layer, a device layer, and a terminal layer in an architectural manner. Data streams are defined for each layer and combined with the Internet of things communication technology. In the horizontal direction, the intra-layer data interaction between devices is realized, and in the vertical direction, the inter-layer intelligent collaboration among sensors, primary devices, terminals, and master stations is realized. In this way, the various information of the ring network cabinet is integrated to the maximum extent. It provides technical support for advanced applications such as state monitoring,operation control, fault prediction, and intelligent operation as well as maintenance of the ring main unit.

Key words: Intelligent operation and maintenance, intension, intelligent ring main unit, condition monitoring
