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
l Sub-ppm detection limit
l 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.
l High anti-interference performance, electromagnetic compatibility performance meets gb/t17626 and iec61000 standards
l Provide two levels of alarm function, alarm signal can be transmitted remotely
l Open database for access to power system LAN
l 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.
l 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.
l 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.
l 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.
l Support iec 61850 communication standard, optical fiber or twisted pair optional
l High degree of system integration, optional with core ground current and ambient temperature and humidity monitoring function
l Double-circuit multi-mode constant temperature control, temperature control accuracy of ± 0.1℃, equipment equipped with automatic constant temperature industrial air conditioner
l Functional interface circuit adopts optocoupler isolation design to further improve system anti-interference performance
l Full digital, remote data transmission, control and parameter settings with Ethernet
