Abstract: An arc mitigation apparatus includes an arc mitigation device and a solar cell. The arc mitigation device is configured to be mounted to a low-, medium-, or high-voltage switchgear. The arc mitigation device is configured to stop or limit current flow within at least one part of the low-, medium-, or high-switchgear when activated. The solar-cell is configured to be located within a compartment of the low-, medium-, or high-voltage switchgear. The solar-cell is configured to cause the arc mitigation device to activate due to radiation from an electrical arc of the switchgear impinging upon the solar-cell.

Abstract: A three-position disconnector switch includes a platform, a power in contact, a power out contact, an earthing contact, and a piston. In a first position, the piston contacts the power out contact and the power in contact. In a second position, the piston contacts the power out contact. In a third position, the piston contacts the power out contact and the earthing contact. The piston moves along an axis to transition between the different switch positions. The power in contact is mounted to the platform, the power out contact is mounted to the platform, and the earthing contact is mounted to the platform.

Abstract: A three-position disconnector switch includes an earthing contact, a power out contact, a power in contact, a piston, and a threaded rod. A length of the piston is such that in a first switch position an outer surface of a wall of the piston makes an electrical contact between the power out contact and the power in contact. The length of the piston is such that in a second switch position the outer surface of the wall of the piston does not make an electrical contact with either the earthing contact or the power in contact. The length of the piston is such that in a third switch position the outer surface of wall of the piston makes an electrical contact between the earthing contact and the power out contact. The piston includes an inner threaded section configured to engage with the threaded rod.

Abstract: 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.

Abstract: A vacuum interrupter includes: one movable contact fixed on a movable contact stem; and one fixed contact with a fixed contact stem. The fixed contact and the movable contact are located in a electrically insulating tube, which is vacuumtightly closed by metal lids at boths sides. The fixed contact stem is placed vacuumtightly on one of the metal lids, and the movable contact stem is guided trough an opening of the opposite metal lid via an axially extendable vacuumtight bellow. In order to create a twist protection of the movable contact stem, a ring disc shaped plastic part with a central opening, through which the movable contact stem is guided, is connected externally to the vacuum interrupter such that inner spanner flats inside the opening complementarily fit closely to external spanner flats of the movable contact stem.

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.
