An apparatus comprises a switchgear (5) having at least one couple of stationary conducting terminals (6) and a switching device (3), such as a circuit breaker, having at least one couple of corresponding movable conducting terminals (2). The switching device (3) is movable with respect to the switchgear (5) along a connection/disconnection direction (CD) between a connection position, wherein the switching device (3) is electrically and mechanically connected to the switchgear (5) by engagement of the movable conducting terminals (2) with the corresponding stationary contacting terminals (6) by means of contact assemblies (1) coupled either to the movable conducting terminals (2) or to the stationary conducting terminals (6), and a disconnection position, wherein the switching device (3) and the switchgear (5) are electrically and mechanically disconnected. The apparatus further comprises at least one vibration-limiting device (7) integrally coupled to either one movable conducting terminal (2) of said at least one couple of movable conducting terminals or to one corresponding stationary conducting terminal (6) of said at least one couple of stationary conducting terminals and conformed such that: when the switching device (3) is approaching the connection position moving along said connection/disconnection direction (CD), the vibration-limiting device (7) does not interfere with the other of the one movable conducting terminal (2) or the one corresponding stationary conducting terminal (6); when the switching device (3) is in the connection position, in case of vibrations of the one movable conducting terminal (2) transversal to said connection/disconnection direction (CD), the vibration-limiting device (7) interferes with the other of the one movable conducting terminal (2) or the one corresponding stationary conducting terminal (6) so to limit the vibrations amplitude.
An apparatus comprising a switchgear having at least one couple of stationary conducting terminals and a switching device having at least one couple of corresponding movable conducting terminals, wherein the switching device is movable with respect to the switchgear along a connection/disconnection direction (CD) between a connection position, wherein the switching device is electrically and mechanically connected to the switchgear by engagement of the movable conducting terminals with the corresponding stationary contacting terminals by means of contact assemblies coupled either to the movable conducting terminals or to the stationary conducting terminals, and a disconnection position, wherein the switching device and the switchgear are electrically and mechanically disconnected, at least one vibration-limiting device integrally coupled to either one movable conducting terminal of said at least one couple of movable conducting terminals or to one corresponding stationary conducting terminal of said at least one couple of stationary conducting terminals and conformed such that:
A vibration-limiting device integrally couplable to either one movable conducting terminal of at least one couple of movable conducting terminals of a switching device or to one corresponding stationary conducting terminal of at least one couple of stationary conducting terminals of a switchgear, wherein the switching device is movable with respect to the switchgear along a connection/disconnection direction (CD) between a connection position, in which the switching device is electrically and mechanically connected to the switchgear by engagement of the movable contacting terminals with the corresponding stationary contacting terminals by means of respective contact assemblies coupled either to the movable conducting terminals or to the corresponding stationary conducting terminals, and a disconnection position, wherein the switching device and the switchgear are electrically and mechanically disconnected to the switchgear, wherein the vibration-limiting device is conformed such that:
