Abstract (en)
The present invention relates to high-voltage electrical switchgear, of the type comprising an enclosure (1); at least one switching mechanism (8, 9) for operating switching means (4, 5), which allow performing breaking, connection, isolation and/or earthing functions; intensity and/or voltage measuring means (6, 7), as well as at least one control/protection device for activating the at least one switching mechanism (8, 9); the present invention fundamentally standing out in that the operation of the switching means (4, 5) depends on the reading of the measuring means (6, 7), such that at least one switching mechanism (8, 9) operates the opening of the switch-disconnector (5) in the case of currents equal to or less than the nominal current, whereas it operates the opening of the circuit breaker (4) before the opening of the switch-disconnector (5) in the case of currents greater than the nominal current.
