KMJ100 SF6 Gas Density Gauge Relay

Main features and functions of KMJ100 SF6 gas density gauge relay

1. Real-time Monitoring and Display
Density Monitoring: The KMJ relay continuously monitors the SF6 gas density within a sealed container, ensuring that the gas remains within a safe range.
On-site Display: It provides a clear, on-site display of the current gas density, allowing operators to quickly assess the status of the equipment.
2. Automatic Alarm and Control Functions
Alarm Contact: When the gas density reaches a pre-set threshold, the relay’s contact mechanism immediately triggers an alarm, indicating potential leakage or other issues.
Control Signal: The relay also outputs a control signal that can work in conjunction with other devices, enabling protective operations such as power disconnection or switching to backup systems, preventing equipment failure.
3. Wide Application Range
Applicable Equipment: The KMJ-type SF6 Gas Density Relay is suitable for a variety of SF6-insulated electrical equipment, such as gas-insulated switchgear (GIS), circuit breakers, pole-mounted switches, transformers, and instrument transformers.
Smart Substation Upgrades: It provides intelligent solutions for both newly constructed substations and retrofitting existing substations, enhancing operational efficiency and safety.
4. Design Advantages
High Reliability: The relay is designed with excellent anti-interference capabilities and long service life, ensuring stable operation even in harsh environments.
Sealed Construction: It features a fully sealed design, preventing external environmental factors from affecting the SF6 gas density measurement.
High Accuracy: Equipped with a high-precision gas density sensor, the relay accurately detects and reflects changes in gas density.
5. Safety Assurance
Leakage Prevention: By continuously monitoring and triggering alarms, the relay can detect SF6 gas leaks in time, preventing electrical faults caused by insufficient gas levels.
High Protection Level: The relay typically has a high protection rating, shielding it from dust, moisture, and other environmental factors.
6. Ease of Maintenance and Operation
The relay is designed to be simple to operate, maintain, and replace, reducing maintenance costs and labor intensity.
