GAS-INSULATED CURRENT TRANSFORMER Russian patent published in 2003 - IPC

Abstract RU 2211499 C2

FIELD: measurement data signal transfer to measuring instruments, protective and control devices. SUBSTANCE: transformer has metal case accommodating primary winding passed through port of secondary winding set enclosed in annular electrostatic shield coupled with grounded tap tube mounted inside insulating cover. Its upper cylindrical metal flange is joined with metal case through flat supporting plate and lower one is installed on supporting base socle. Insulating disks are mounted at metal case sides and each of them carries clamping members for connecting transformer primary winding and terminal lead. Primary-winding electrostatic shield is made in the form of cylinder accommodating a number of cable jumpers, each incorporating primary- winding bundled connecting wires. Each bundle is placed in heat-shrinkage pipe carrying lugs at its ends for connecting cable jumpers to insulating disks disposed in inner drillings of carrying metal flanges. Supporting base mounts insulating plate connected to secondary-winding set wires emerging from grounded tap pipe and has gas filler nipple. Bottom part of metal case carries terminal strip whose slots receive connecting wires of cable jumpers emerging at transformer terminal lead end. EFFECT: enhanced reliability; reduced material input and labor consumption. 20 cl, 15 dwg
