What Is Tank-type SF6 Relay?

The sealed tank SF6 relay is a critical device designed specifically for monitoring the density of SF6 gas in sealed containers, primarily used in high-voltage electrical equipment, especially those utilizing SF6 gas as an insulating medium. Its specialized design allows it to function in harsh outdoor environments, ensuring efficient operation of equipment under various conditions.

Key Role of SF6 Relay

In medium and high-voltage systems, gas density is a crucial operational parameter. The SF6 relay monitors the density of SF6 gas within sealed containers, ensuring it remains within specified requirements. Failure to meet these requirements jeopardizes operational safety. Even in extreme conditions, this relay reliably emits warning signals, prompting maintenance personnel to take necessary actions.

Application in Medium and High-Voltage Switchgear

SF6 relays find widespread use in medium and high-voltage switchgear, ensuring appropriate gas density during operation.

Monitoring SF6 Tank Gas Density

Specifically designed for enclosed SF6 tank monitoring, accurately detecting gas density to prevent safety hazards caused by leaks.

Application in Ring Main Units

SF6 relays also play a crucial role in ring main units, ensuring equipment reliability in complex environments.

Unaffected by Atmospheric Pressure and Altitude

Designed to operate in various environments, the SF6 relay remains unaffected by atmospheric pressure and altitude, enhancing product reliability.

No Recalibration Needed

This feature reduces maintenance costs while ensuring high precision even after prolonged use.

Fully Welded Seal with Automatic Temperature Compensation Function

The instrument employs a fully welded seal with temperature compensation, ensuring accurate density information across different temperatures.

Efficient Application of Temperature Compensation Principle in SF6 Relay

The SF6 relay utilizes a temperature compensation principle based on the nonlinear variation of SF6 gas molecular equations. This model guarantees excellent accuracy and temperature compensation, leveraging the characteristics of SF6 gas to provide precise density information under various working conditions. Through compensation systems, the relay maintains stable signal output despite pressure changes induced by temperature fluctuations, effectively preventing false alarms.

The application and design of sealed tank high and medium-voltage SF6 relays fully demonstrate their criticality and reliability in power systems. By effectively monitoring SF6 gas density, equipment can efficiently operate under various complex and unforeseen circumstances. This advanced technology provides robust security and stability for power system operation.
