During routine inspections at substations, how can small sulfur hexafluoride gas leaks be quickly pinpointed? This is an on-site issue that many technical engineers care about. The DRD-8800 quantitative gas leak detector, based on dual infrared spectroscopy technology, provides a quantitative solution for gas leak detection in power equipment.
The instrument uses dual infrared spectroscopy technology, with a sensitivity of 1 ppm and an accuracy of ±8%. A built-in microprocessor monitors the sensor head and battery voltage in real time, with up to 4,000 samples per second, and can promptly compensate for signal fluctuations even when they are very small, helping to detect abnormalities at the early stage of a leak.
The instrument has high power supply voltage stability, low temperature rise, low heat loss, and good thermal stability. This design helps reduce measurement deviation caused by temperature drift during long periods of continuous operation, making it suitable for high-load on-site use.
It is suitable for leak detection of SF6 circuit breakers, GIS switchgear, instrument transformers, and other equipment in power systems, and can also be used for routine inspection and maintenance of gas-insulated switchgear. Technical engineers can use its quantitative function to assess concentration trends in suspected leak areas and assist in formulating maintenance strategies.
After power-on, preheating is required and the battery voltage indication should be observed, and the sensor head filter should be cleaned regularly. In heavily polluted environments, it is recommended to shorten the calibration cycle to maintain the reference value of the measurement results.
