Abstract (en)
[origin: CA2080517A1] 13 ELECTRICAL CIRCUIT BREAKER WITH TWO VACUUM CARTRIDGES IN SERIES Inside a sealed enclosure (10) filled with sulphur hexafluoride there are housed main contacts (17,19) and parallel with the latter an auxiliary circuit comprising two vacuum cartridges (20,21) electrically connected in series. The 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 gasinsulated installations or substations. Refer to figure 1.
