METHOD OF MANUALLY DECOCKING A DOUBLE-LATCHING MECHANISM OF A HIGH-VOLTAGE OR MEDIUM-VOLTAGE ELECTRICAL CONTROL APPARATUS, AND ASSOCIATED CONTROL

摘要

The invention relates to a novel high-voltage or medium-voltage electrical control apparatus (5) provided with at least one switch, comprising: a double-latching mechanism; and retractable mechanical connection means, which can be moved between a deployed position in which it connects an element (50) of the double-latching mechanism with an element (3) of an apparatus mechanically connected permanently to the switch in the installed configuration of the apparatus and a retracted position in which it disconnects them. According to the invention, a cover for the interface with the outside and a button (52) placed so as to project outwardly from the cover are provided, whereby, by pulling said button, a drive shaft is moved translationally from its deployed position to its retracted position, thus accomplishing the mechanical disconnection.
