I.Overview
HZZQ-2300 automatic insulating oil gas evolution tester conforms to the standard ASTM D2300, GB/T11142-89 "Determination of gas evolution properties of insulating oil under electric field and ionization" standard (also in line with national industry NB/SH/T0810-2010 " Determination of gas evolution properties of insulating oil under the action of electric field and ionization "Standard), a method for measuring the tendency of insulating oil to release and absorb gas under the action of an electric field strong enough to cause discharge at the junction of oil and gas.
The instrument adopts MCS-51 series single chip microcomputer as the system control core, and the configuration of 7-inch 256-color intelligent color screen display and screen touch keys ensures the advanced nature and reliability of the whole machine; Chinese LCD display, man-machine menu-type dialogue, wizard operation. The measurement process is all completed automatically, that is, automatic constant temperature oil bath at 80 °C, automatic hydrogen charging, automatic opening and closing of the straight valve; automatic measurement of gas evolution after 10 minutes of power on and 50 minutes of power on, and automatically calculate the gas evolution G value of the sample;G=(B60-B10)×1000/50; (See GB/T11142-89 standard); The instrument uses infrared optical fiber optical cable sensing technology to detect the flowing liquid level to ensure the accuracy and precision of the measurement. It is characterized by reliable operation, simple operation and high precision. It is widely used in petrochemical, electric power, railway, scientific research and other departments. It is an indispensable equipment for oil analysis and quality inspection.
