KMJ100 SF6 Gas Density Gauge Relay
The KMJ-type SF6 Gas Density Relay is a crucial device used for monitoring the density of SF6 gas in sealed electrical equipment. It ensures the safe and normal operation of equipment by providing real-time density measurements. Below are its main features and functions:
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.
