摘要： The circuit breaker system contains a plurality of phase conductors, a circuit breaker having a plurality of breaker poles, and a short-circuit link having a star point and a plurality of link conductors combined at the star point. Each of the phase conductors is electrically conductively connected to in each case one of the breaker poles and each link conductor is electrically conductively connected to in each case one of the phase conductors in each case one of several first disconnectors to which short-circuit current can be applied. In order to avoid expenditure on assembly and downtimes of the circuit breaker system when carrying out simulation experiments with the aid of the short-circuit link, the circuit breaker system contains a second disconnector which, when closed, electrically conductively connects the star point to ground and which is opened when a short-circuit current is applied to the short-circuit current link.

摘要： A solenoid-driven automatic bus transfer switch may automatically transfer one or more electrical loads from a first power source to a second power source, or vice versa, in the event of a power failure or other casualty that affects either power source. The transfer switch may be operated in response to the energization of a solenoid coil, which causes a main shaft having a transfer element to rotate from being in contact with the first power source to being in contact with the second power source. The transfer element may be spring-mounted to the shaft, which ensures that a sufficient electrical contact exists between the surfaces of the transfer element and the respective leads of the first and second power sources, regardless of any wear or degradation that may be experienced at any of the surfaces.

摘要： A three-positions disconnector comprising, for each phase an insulating casing which comprises a first and a second cavity separated by an insulated partition wall, a through hole being present in said partition wall between said first and second cavity. The first cavity houses: a first fixed contact electrically connected to a corresponding branch conductor (of a bus-bar system; at least a portion of a movable contact pivotally mounted on a support positioned in the first cavity and electrically connected to a first electrical terminal positioned in said second cavity. The disconnector further comprises, for each phase, a second fixed contact suitable for ground connection. Also, the disconnector comprises an operating mechanism and a kinematical chain linking the movable contact with the operating mechanism; the movable contact is movable between a first position in which it is coupled to the first fixed contact, a second position in which it is isolated from both the first and second fixed contacts, and a third position in which it coupled to the second fixed contact.

摘要： A transfer switch that includes output contacts, primary input contacts, secondary input contacts and a switch stack. The switch stack alternately connects the output contacts to the primary input contacts and the secondary input contacts via at least one conductive path. The transfer switch further includes at least one flux barrier that is at least partially positioned near the conductive path to minimize magnetic interaction with the conductive path as current travels through the switch stack.

The adjoining shaft segments are joined to each other by a respective coupling element, each coupling element including two tab-shaped parts joined to each other by a support shaft. Each tab-shaped part supports at least two first connecting pins on a side facing away from the support shaft and extending in an axial direction. The shaft segments each include recesses a side facing the coupling element, the recesses for receiving the connecting pins. A support, or bearing, for supporting the support shaft is provided in the arcing chamber housing in a transition area between adjacent arcing chambers.
