Abstract
The utility model provides an online monitoring system for density and trace moisture of SF6 (sulfur hexafluoride). The system is used for monitoring SF6 in a high-pressure unit and comprises a monitor, a monitor host and an upper PC (personal computer). The system is characterized in that signals output from a detector are transmitted to the monitor host through a RS-485 bus, and signals from the monitor host are transmitted to the upper PC through a wired network or wireless network. Real-time data acquisition and monitoring for moisture content and density of SF6 are achieved.
Description
Technical field
The present invention relates to a kind of industrial generative process monitoring system, especially relate to a kind of SF
6Gas density and little water on-line monitoring system.
Background technology
Being widely used of high-tension apparatus is greatly improved the security of equipment in recent years, SF in the high-tension apparatus
