2. Automation and Intelligence: Built in microprocessor, automatically controls pressure rise and fall, accurately captures contact movements, records data, and completes verification with one click, greatly improving work efficiency.
3. Portable design: The device has high integration, small size, light weight, and is equipped with long-lasting batteries, making it very suitable for mobile work needs in substations.
4. Comprehensive functions: It usually has functions such as pressure verification, temperature measurement, data storage, and report generation. Some advanced models support wireless communication to achieve remote data management.
5. Safe and efficient: By verifying the normal operation of the density relay, it can timely and accurately reflect the SF6 gas leakage situation, which is a key tool for preventing equipment failures and ensuring the safe and efficient operation and maintenance of the power grid.
Main applications
1. Regular verification: Conduct periodic verification of SF6 equipment density relays in operation according to regulations to ensure the accuracy of their alarm and locking contact action values.
2. Pre commissioning verification of new equipment: Conduct acceptance verification of the density relay of newly commissioned SF6 electrical equipment at the installation site.
3. Fault diagnosis: When the monitoring system sends out density abnormal signals or equipment abnormalities, the density relay is verified to determine whether the equipment is leaking air or the relay is giving a false alarm.
