The SF6 micro water density online monitoring system is a key research and development project established by our company in accordance with the development requirements of the national smart grid. This series of products adopts advanced measurement and perception technology and backend computer technology. The system is compact and has a small appearance, which can achieve high-precision measurement, post-processing by the computer, massive historical data storage function, and is suitable for online monitoring of SF6 gas micro water, density, and temperature in SF6 circuit breakers, GIS, HGIS, GIL and other equipment of various voltage levels. It achieves advanced dynamic monitoring such as no emissions, environmental protection, safety, real-time, and remote monitoring to meet the needs of power distribution automation and equipment status maintenance.
system architecture
The system consists of a process layer, an interval layer, and a station control layer. The process layer includes density transmitters (for measuring temperature, density, and temperature functions) and micro water density transmitters (for measuring micro water, density, and temperature functions). The interval layer is the micro water density online monitoring device (system host), and the station control layer is the background monitoring software. The system host and transmitter are connected by cables. The sampling pool inside the transmitter also adopts internal circulation technology, which can measure real-time parameters such as micro water, density, and temperature of SF6 in the equipment, achieve real-time display, and communicate and exchange data with the system host. After extracting data from various transmitters in a time-sharing manner, the system host uploads the data to the backend computer for processing, and can also accept instructions from the backend to achieve real-time sampling and other actions.
