, Metal-encased, pressurized-gas-insulated high-voltage switchgear with a measuring transducer

摘要

To install a measurement transducer (3), whose secondary system is arranged on a tube (5), in the encapsulation housing (1) of a pressurised-gas-insulated high-tension switch gear installation with a centrally located conductor (2), the encapsulation housing (1) has a wall (13) directed radially inwards and attachment straps (15), located opposite it at a plurality of points on the circumference. A slanting plane (14) is provided in the wall (13). The protective electrodes (8) laterally bounding the tube (5) of the measurement transducer (3) are provided at the same points in each case with perforations (10) which project above the back (12) of the measurement transducer (3). A spacer bolt (17) is in each case screwed into the attachment straps (15) of the encapsulation housing (1), which spacer bolt passes through the perforations (10) on both end faces (6, 7) of the measurement transducer (3), and its end (18) presses against the slanting plane (14).
