Abstract:
A locking device of a reversible plug-in and disconnection mechanism designed to be driven by a removable operating part, for a switchgear apparatus with disconnection by extraction designed to be placed in several states, the device comprising:a main locking catch comprising a mobile element able to assume a closed position for preventing the operating part from being fitted and an open position for enabling the operating part to be fitted;a first operating means for operating said main locking catch and to which one or more of said states of the switchgear apparatus are associated, said first operating means capable of assuming a state in which the first operating means determines if the apparatus is not in one of said associated states and in which the first operating means prevents the mobile element of the main locking catch from moving to its closed position when the apparatus is not in one of said states, wherein the first operating means may move in reversible manner from its active state to a passive state in which the first operative means cannot prevent the main locking catch mobile part from moving to its closed position; andan operating mode selector comprising a selection part able to move reversibly from a first position in which the selection part maintains the first operating means in its active state throughout a plug-in and disconnection cycle, to a second position in which the selection part maintains the first operating means in its passive state throughout the plug-in and disconnection cycle.
