Definitions
- At least one protection component provided with connection means to the electrical installation
- Another object of the invention is to propose a new device for protecting electrical installations against overvoltages which is particularly robust and resistant.
- a means for disconnecting the protection component with respect to the electrical installation adapted to ensure the disconnection of the latter at the connection means, and capable of moving from a closed position to a closed position; opening position by creating an interstitial space between the disconnecting means and the connecting means, characterized in that it comprises anti-recoil means adapted to prevent the disconnection means from returning to its closed position when the latter separates the connection means from an isolation distance greater than a predetermined threshold distance.
- the disconnection means 30 is formed by an electrically conductive elastic disconnecting disc 31 (for example made of metal) which, in the closed position, is prestressed, that is to say advantageously welded in stress on the connection means 20, specifically on the electrode 21, preferably using a heat-fusible seal (not shown).
- an electrically conductive elastic disconnecting disc 31 for example made of metal which, in the closed position, is prestressed, that is to say advantageously welded in stress on the connection means 20, specifically on the electrode 21, preferably using a heat-fusible seal (not shown).
- the anti-recoil means 50 thus make it possible to prevent the disconnection means 30, and in particular the elastic disconnection blade 31, from going back when the optimum isolation distance is reached.
- the anti-recoil means 50 also make it possible to limit the phenomenon of oscillation of the elastic disconnection blade 31.
- the anti-recoil means 50 comprise a movable member 51 adapted to move under the control of the opening movement of the disconnection means 30.
- the movable element 51 is preferably designed to come, in its operative position, in active support against the disconnection means 30 when the predetermined threshold distance d is reached ( Figure 1).
- the movable element 51 comes, in its operative position, to be positioned at least partly in the path of the disconnection means 30, thus forming an obstacle against the latter and preventing the disconnecting means 30 to go back to the connection means 20, in particular to the electrode 21, once the predetermined threshold distance has been reached.
- the protection device 1 advantageously comprises an additional locking means 56 adapted to cooperate with the anti-recoil means 50 so as to immobilize the disconnection means 30 in its open position, as shown in Figures 1 and 4.
- the elastic disconnection blade 31 is subjected, in its closed position, to an intrinsic elastic return force F '(FIG. 3) tending to return it to its open position illustrated in FIG. recess 50 are then designed to oppose the movement of the elastic disconnection blade 31 in a direction F "( Figure 4) substantially opposed to the intrinsic elastic return force F ', when the predetermined threshold distance d is reached.
