摘要： A medium voltage circuit switch or breaker includes: at least one movable contact; a fixed contact; and a mechanical or magnetical drive system, which moves the at least one movable contact to a closed or opened position by a movement of a rod and/or a lever. The mechanical or magnetical drive system is linked to a switching generating signal. The mechanical or magnetical drive system includes at least one pyrotechnical actuator or gas generator. The pyrotechnical actuator or the gas generator is linkable to the switching generating signal of the mechanical or magnetical drive system.

摘要： A contact assembly for connecting electrically and mechanically a first terminal of a first apparatus to a second terminal of a second apparatus, wherein at least one of the first and the second apparatus is movable with respect to the other along a connection/disconnection direction, includes: a plurality of electrically conducting contact-finger-elements, each including a main contact portion configured for engaging the second terminal and an auxiliary contact portion for engaging the first terminal, wherein the finger-contact-elements are supported by a support frame of the contact assembly connectable to the first terminal or are configured for being directly connectable and supportable by the first terminal; one or more spring elements configured for acting on the contact-finger-elements so to urge the main contact portions against the second terminal when the first and the second apparatus are connected. The main contact portions of at least two of the plurality of contact-finger-elements are shifted one relative to the other in such a manner so to engage the second terminal in subsequent moments when the first apparatus is being connected to the second apparatus by a relative movement thereof along the connection/disconnection direction.

摘要： An apparatus comprises a switchgear having at least one couple of stationary conducting terminals and a switching device, such as a circuit breaker, having at least one couple of corresponding movable conducting terminals. The switching device is movable with respect to the switchgear along a connection/disconnection direction 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. The apparatus further comprises 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: when the switching device is approaching the connection position moving along said connection/disconnection direction, the vibration-limiting device does not interfere with the other of the one movable conducting terminal or the one corresponding stationary conducting terminal; when the switching device is in the connection position, in case of vibrations of the one movable conducting terminal transversal to said connection/disconnection direction, the vibration-limiting device interferes with the other of the one movable conducting terminal or the one corresponding stationary conducting terminal so to limit the vibrations amplitude.

摘要： 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.
