Product description Wireless remote SF6 gas density relay (WINFOSS-D6XR) is mainly used to monitor the density of SF6 gas in sealed containers. It is mostly used in high-voltage electrical equipment with SF6 gas as the insulating medium, and is suitable for outdoor working environments. The density relay has two or three groups of contacts (defined according to different needs), which can send out alarm and lock control signals, and have indication display. SF6 gas density relay can be filled with silicone oil to improve shock and shock resistance. With the development of unattended substations in the direction of networking and digitization and the requirements for telemetry and remote signaling, it is of great practical significance to realize online monitoring of SF6 gas density in substations with Internet of Things technology.

The SF6 gas density relay with wireless remote transmission function sends the collected data monitoring data to the on-site monitoring unit through wired 4-20mA or RS485; the on-site monitoring unit uploads the collected SF6 density meter data to the main control unit through the wireless LORA network. The main control unit stores, displays and processes the received data; when the high-voltage electrical equipment leaks SF6 gas, the data processing server can immediately indicate the pressure or density changes caused by the leak, and give an early warning signal to prompt maintenance personnel to perform system maintenance. The historical measurement data of SF6 density stored on the main control unit can be queried by the staff and the remote management system.
