Abstract

The measuring device is intended for a metal-enclosed, gas-insulated high-voltage installation. It contains at least one sensor (10, 11), arranged in an enclosure tube (3) of the metal enclosure which is filled with insulating gas, and at least one electronic evaluation device (23, 23'), which processes output signals of the sensor (10, 11). The evaluation device (23, 23') and a plug-and-socket device (28, 28') connecting the evaluation device to an output of the sensor (10, 11) are arranged in a two-part metal housing. One part of this housing is formed by a hollow metal flange (26), integrally formed on the outer surface of the enclosure tube (3), and the region of the enclosure tube (3) rimmed by the hollow flange (26). The other part of the housing is a housing element (27) which is depressed in the shape of a trough and is fastened to the hollow metal flange (26) of the enclosure tube (3) by its edge, which delimits the trough opening. This measuring device is distinguished by a compact design and, because of the local control, by a high measuring accuracy and a high operational reliability.
