Introduction to SF6 Micro Water Density Online Monitoring

To adaptGas insulated high voltage switchgearonline monitoringthe need forBased on online monitoring technology, our company has developed a state maintenance mode that combines fault diagnosis and preventive measures to achieve maximum reliability and reduce cost consumption. Our company has developed a state maintenance mode with independent intellectual property rightsSF₆Gas online monitoring system. This device is capable of long-term online monitoring of circuit breakers with measurement accuracy higher than national standardsSF₆The density, micro water content, temperature, and their changing trends of gases serve the purpose ofSF₆When gas related indicators change, provide a change curve; When the relevant indicators reach the alarm state, the alarm or automatic alarm device will be activated; When the relevant indicators exceed the standard and reach a dangerous situation, an alarm or automatic locking device is activated to prohibit the operation of the circuit breaker, in order to ensure the safety of the equipment and the entire substation system. The above monitoring equipment is equipped withThe RS-485 communication interface can upload monitoring data in real-time to substations, city centers, and even higher-level monitoring centers, truly realizing online monitoring of equipment in substations, especially unmanned stations. At the same time, the monitored changes in various indicators provide effective basis for the maintenance of circuit breakers.
