    摘要: A fixation system in use for medium or high voltage switching poles, insulators, circuit breakers, or general devices includes: an insulating housing provided with holes, in which screws are screwed into, in order to fix the device on a support, or a further housing. Inner surfaces of the holes are covered with a conductive layer or layers covering the inner surfaces at least partly. The conductive layers extend toward outside the holes. The conductive layers are conductively connected or connectable to ground potential.

    摘要: An earthing module for a switchgear includes: a cylinder; a piston; a stored energy unit; and at least one photovoltaic cell. The cylinder connects to a part of a switchgear at earth potential. The piston moves within the cylinder from a standby position to a released position along an axis of the cylinder. When in the released position, the piston is in electrical connection with the cylinder. The stored energy unit is located within or associated with the earthing module such that activation of the stored energy unit moves the piston from the standby position to the released position. One or more of the at least one photovoltaic cell activates the stored energy unit based on radiation from an electrical arc of the switchgear impinging upon the one or more of the at least one photovoltaic cell.

    摘要: A short circuit current detection device for a medium voltage or high voltage switchgear includes: a reed contact; and a holder for holding the reed contact, the holder being mountable with a defined orientation to a conductor of the switchgear. At a location where the holder is mounted, the conductor has a longitudinal axis. The conductor enables a current to flow through the conductor in a direction of the longitudinal axis. The holder positions the reed contact with respect to the longitudinal axis such that when a magnitude of the current flow through the conductor exceeds a threshold current value the reed contact closes.

    摘要: The invention relates to a medium voltage switching apparatus. The medium voltage switching apparatus includes one or more electric poles, each electrically coupleable with a corresponding electric line; for each electric pole, a fixed contact and a movable contact, the movable contact being reversibly movable between a decoupled position from the fixed contact and a coupled position with the fixed contact, the movable contact moving from the decoupled position to the coupled position during an closing manoeuvre of the switching apparatus and moving from the coupled position to the decoupled position during an opening manoeuvre of the switching apparatus; and actuating means adapted to actuate the movable contacts of the one or more electric poles. A control unit is adapted to select and carry out a selectable control routine in response to receiving an input signal at an input arrangement corresponding to the selectable routine.

    摘要: An electrical connection for medium and high voltage switchgears includes an electrical terminal of a switchgear. An electrical contacting surface of the electrical terminal as first current carrying part is electrically connected with a contacting surface of an external electrical connector part as second current carrying part via a connecting system. The connecting system includes a stretch-bolt function, which is integrated in one of the current carrying parts. The stretch bolt function is provided with a male screw thread at the extending end, which is configured to be screwed into a female threaded hole of the second current carrying part.

    摘要: 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.
