Abstract
An arrangement for testing metal-clad, high-voltage installations includes an equipment unit having a separate encapsulation for accommodating the apparatus for making the tests. The separate encapsulation can be flanged as a unit to the installation to be tested. The arrangement is particularly suited for detecting partial discharges in metal-clad, high-voltage installations which are filled with an insulating gas, such as sulfur hexafluoride.
Claims6
An arrangement for making tests on a metal-clad, high-voltage installation filled with insulating gas, particularly tests for detecting partial discharges, comprising a flange formed on the metal enclosure of the installation and defining an access opening in the same;
- an equipment unit having a metal encapsulation for accommodating the apparatus for making the tests, said metal encapsulation having a flange for removably engaging said flange of the metal enclosure of the installation;
- and, cover means for covering said access opening when said equipment unit is not attached to the metal enclosure of the installation.
An arrangement for making tests on a metal-clad, high-voltage installation filled with insulating gas, particularly tests for detecting partial discharges, comprising structure means defining an access opening formed on the metal enclosure of the installation;
- and, an equipment unit having a metal encapsulation for accommodating the apparatus for making the tests, said encapsulation having a flange for removably engaging said structure means of the metal enclosure of the installation and said encapsulation being made up of a plurality of individual housing elements one adjacent the other for accommodating respective components of the apparatus, each of said housing elements having respective longitudinal flanged ends for mutually connecting each two mutually adjacent ones of said housing elements, a first one of said housing elements being adjacent the metal enclosure of the installation, the component contained therein being voltage feed-in means for supplying voltage to the installation when conducting the tests thereon;
- a second one of said housing elements being disposed away from said first housing element, the component contained in said second housing element being coupling means for coupling an instrument to the installation for measuring the partial discharges;
- and a third one of said housing elements being disposed intermediate said first and second housing elements, the component contained in said third housing element being a grounding-disconnect switch for grounding said coupling means and disconnecting the same from the installation.
