Abstract
Inside a sealed enclosure (10) filled with sulphur hexafluoride there are housed main contacts (17,19) and an auxiliary circuit comprising two vacuum cartridges (20,21) electrically connected in series with each other and in parallel with the main contacts. The vacuum cartridges (20,21) are operated by a single mechanism to open and close simultaneously and serial connection enables the voltage withstand to be increased. The invention can be applied to medium or high voltage gas-insulated installations or substations.
