Measuring device for a metal-enclosed, gas-insulated high-voltage installation
First Claim
1. A measuring device for a metal-enclosed, gas-insulated high-voltage installation having at least one Rogovski coil, which is arranged in an enclosure tube, filled with insulating gas, of the metal enclosure and serves to detect the current in a current-carrying conductor led through the enclosure tube, having at least one measuring electrode, which surrounds the conductor and serves to detect the voltage of the conductor, and having at least one electronic evaluation device, which processes output signals of the Rogovski coil and the measuring electrode, wherein the current conductor is rigidly connected to a current-conducting cast armature of an insulator fastened to the enclosure tube.

Abstract
The measuring device is intended for a metal-enclosed, gas-insulated high-voltage installation. It contains at least one Rogovski coil (10), which is arranged in an enclosure tube (3), filled with insulating gas, of the metal enclosure and serves to detect the current in a current-carrying conductor (9), led through the enclosed tube (3), and a measuring electrode (11), which surrounds the conductor (9) and serves to detect the voltage of the conductor (9). The current conductor (9) is rigidly connected to a current-conducting cast armature (13) of an insulator (14) fastened to the enclosure tube (3). In the measuring device according to the invention, a defined field geometry is maintained in the interior of the enclosure tube (3) even over long periods and under changing loads. Consequently, the sensors, in particular the voltage sensor containing the measuring electrode (11), can transmit output signals of high measuring accuracy.
