Abstract (en)
[origin: WO02097839A1] A control for at least one vacuum breaker gap on a high voltage switchgear is disclosed, whereby at least one ohmic control resistance (3, 4, 11, 12, 13, 23, 24, 25, 26, 27, 28, 33, 34) is arranged in parallel with the vacuum breaker gap (1, 8, 9, 10, 17, 18, 19, 31, 32). Said at least one ohmic control resistance is arranged concentrically around the vacuum breaker chamber (38, 39, 40) and is mechanically and electrically coupled thereto.
