SF6 DENSITY RELAY, MIXED GAS DENSITY RELAY

The sulfur hexafluoride (SF6) density relay is a monitoring and protection device specially used in high-voltage electrical equipment. By monitoring the pressure and temperature of the SF6 gas, it ensures that the gas density inside the equipment remains within a safe range, thereby preventing equipment faults or damage caused by gas leakage or excessively low density. Application Scenarios: Widely used in equipment such as high-voltage circuit breakers and disconnectors to ensure the safety and stability of equipment under high-voltage operation. It is suitable for monitoring SF6 gas sealing systems in substations, power plants, and other high-voltage electrical equipment. This relay can timely prevent accidents from occurring

DIGITAL REMOTE TRANSMISSION DENSITY RELAY

The SF6 digital remote‑transmission density relay is an upgraded version of the conventional SF6 density relay. It integrates digital measurement and remote transmission capabilities, enabling more intelligent monitoring of SF6 gas conditions and transmitting real-time data to a remote monitoring center via data communication technologies. This type of relay is particularly well suited for the intelligent management and remote operation and maintenance of modern power systems. Application scenarios: Power systems—suitable for substations, high‑voltage circuit breakers, gas‑insulated switchgear (GIS), and other applications, providing remote, intelligent monitoring of SF6 density. Smart grids—integrated with smart grid management systems.
