INSTALLATION FOR ELECTROTHERMOVACUUM RECOVERY AND REPAIR OF INSULATION OF ELECTRICAL PRODUCTS Russian patent published in 2002 - IPC

FIELD: electrical engineering. SUBSTANCE: groups of parallel vessels communicating with the atmosphere are connected to a vacuum pump through pipe-lines provided with shut-off devices. Quick-acting vacuum valves and the receiver of the first autoclave and varnish accumulator, the second autoclave and the reservoir for aqueous solution of carbon dioxide connected to a cylinder with carbon dioxide used in the installation are used as quick-acting shut-off devices. The upper parts of the first autoclave, varnish accumulator, second autoclave, reservoir for aqueous solution of carbon dioxide communicate with the atmosphere through shut-off devices. The lower parts of the varnish accumulator, reservoir for aqueous solution of carbon dioxide communicate with the atmosphere through the shut-off devices. The lower parts of the first autoclave, varnish accumulator, second autoclave and reservoir for aqueous solution of carbon dioxide are interconnected in pairs through the shut-off devices, quick-acting vacuum valves are used as shut-off devices. The installation is designed for realization of two independent production processes: impregnation and drying of insulation, break-down of insulation of electrical products, for example, stators of electric motors. EFFECT: enhanced capacity and economical efficiency of the installation due to the reduced loss of time for realization of the recovery work, and enhanced quality of insulation. 5 cl, 1 dwg
