Abstract: An on-load tap-changer of a tap-changing transformer has a switch. The switch has: a take-off contact; a primary fixed contact; and a contact unit. The contact unit has a moving contact, a first arcing contact and a second arcing contact. These contacts are pivotable about a pivot axis during a switchover process such that the contacts assume a first position, in which they make contact with the take-off contact and the primary fixed contact, and a second position, in which they are separated from the take-off contact and the primary fixed contact. The second arcing contact assumes the first position before the first arcing contact when switching over from the second position to the first position and leaves the first position after the first arcing contact when switching over from the first position to the second position.

Abstract: A medium voltage switching pole includes: a fixed contact of a vacuum interrupter; a movable contact of the vacuum interrupter; a piston; at least one electrical contact; a first terminal; and a second terminal. The fixed contact is fixedly connected to the first terminal. The movable contact is fixedly connected to the piston. The piston moves within the second terminal along an axis. The at least one electrical contact makes an electrical connection between the piston and the second terminal. An outer surface of the piston and an inner surface of the second terminal are arranged such that: when in an open configuration the fixed contact and movable contact are separated, at least one first radial line perpendicular to the axis extends through locations of the at least one electrical contact, and a first distance along the at least one first radial line extends from the outer surface.

Abstract: A vacuum circuit breaker 10 comprising a vacuum interrupter 12 coupled between upper 18 and lower 20 terminals and being operable to make or break an electrical connection between the upper and lower terminals. The circuit breaker has a body 22 formed from electrically insulating material, the vacuum interrupter being located in an internal chamber of the body. The lower terminal 20 comprises a hollow body 26 that forms part of the internal chamber and which is shaped and dimensioned to allow the vacuum interrupter 12 to pass through it. An electrical connector device 50 has a movable part 52 that is connected to the movable contact and an annular fixed part 54 that is connected to the lower terminal 20. The movable part 52 is connected to the first part 54 by flexible connectors 56, and has a socket (58) for engaging an electrical connector 60 of the vacuum interrupter 12. A pulling rod 16 is coupled to the movable contact via the electrical connector 60.

Abstract: The present disclosure provides a conductive member for a circuit breaker high voltage portion conductor assembly, the conductive member including a body with a transfer portion and a coupling portion. The body transfer portion has an electro-thermally efficient contour. That is, the body transfer portion has an electrically efficient contour and a thermally efficient contour. The body transfer portion includes a number of slots defining fins. In this configuration, the body transfer portion distributes current generally evenly across a cross-sectional area of the conductive member body. Further, the fins provide heat dissipation via convection.
