DEVICE DETECTING HYDROGEN AND MOISTURE DISSOLVED IN DIELECTRIC LIQUIDS Russian patent published in 1999 - IPC

FIELD: analysis of liquids with use of ultrasound. SUBSTANCE: invention can be used to detect hydrogen and moisture in electrical insulating oils. Device detecting hydrogen and moisture has vessel for dielectric liquid, unit measuring concentration of released gas, vacuum pump and ultrasonic radiator with spherical radiating surface. Vessel for liquid is made of two part one being put on radiator. Upper part of vessel is connected with pipe-lines to vacuum pump, multiway cock made with container for calcium hydride and optical dish that is part of unit for selective registration of molecular hydrogen. Additional container for calcium hydride is installed in pipe-line. Device may carry additional ballast vessel connected to optical dish. Ground-in piston can be installed in ballast vessel. Conical screen with central hole can be mounted on connector of upper and lower parts of vessel for dielectric liquid. EFFECT: increased functional reliability of device. 5 cl, 2 dwg
