SF6 Gas Monitor and Receiver Based on LoRa Wireless Transmission Technology
SF6 (Sulfur Hexafluoride) gas is widely used as an excellent insulating and arc-suppressing medium in medium and high voltage, as well as in high voltage switchgear and GIS. The density index of SF6 gas is crucial to its insulation and arc-suppressing performance.
SF6 Gas State Monitor and Receiver (LS-WC and LS-WT series) are self-developed monitoring products by our company. The monitor can adapt to our full range of transmitters and remote density relays, monitoring SF6 gas pressure, temperature, density, and moisture content in real time. The data is transmitted back to the background system in real time through wireless LoRa data transmission. The background system can perform online monitoring and analysis, and achieve functions such as real-time data query, historical data statistics, pre-set alarm reminders, and data curve query for all data. This system is mainly designed for real-time monitoring of critical equipment such as SF6 gas insulated switchgear, GIS, transformers, a
