Technology:
The DK-200F oil gas analyzer can realize gas analysis in multi-component oil, and the high-sensitivity measurement of short-path optical path can be realized by Finnish interference company's photoacoustic spectroscopy technology. Ultra-high sensitivity based enhanced cantilever beam Optical microphone technology enables linear dynamic range ratios up to 5 steps. Ultra-high sensitivity is achieved with 7 optical narrow-band filters. Extremely narrow optical filtering removes background gas interference; multiple spectral regions can be beneficial The smallest cross-sensitivity. The multi-gas analyzer is based on infrared photoacoustic spectroscopy technology. It has a pulsed infrared light source and passes through a narrow-band optical filter to form seven spectral bands in the mid-infrared region for gas analysis.
Characteristic:
Sub-ppm detection limit
The oil and gas separation speed is fast, and special environmental adaptation technology is adopted to eliminate the influence of temperature and humidity changes on the gas distribution coefficient.
High anti-interference performance, electromagnetic compatibility performance meets gb/t17626 and iec61000 standards
Provide two levels of alarm function, alarm signal can be transmitted remotely
Open database for access to power system LAN
Faster analysis cycle with a minimum monitoring period of 10 minutes, which can be set by the user. The recommended detection period is 12 hours.
The system has a secondary gas threshold alarm and a growth rate alarm function, and the alarm concentration and growth rate can be set arbitrarily.
Equipped with an expert system for judging latent faults, the latest fault diagnosis technology uses the iec60599 standard and the improved fuzzy three-ratio method, David triangle, cubic graphic method and other methods.
It has historical data trend graph query, report format display and printing function, which is convenient for longitudinal comparison of monitoring data to analyze transformer operation and fault development trend.
