Abstract: A method for operating a drive of a vacuum interrupter in opening mode includes: dividing an opening movement of at least one movable contact into serial phases, an opening phase, and an isolating phase, driven in at least two different velocities. In the opening phase a velocity of the opening movement is lower than in the isolating phase.

Abstract: A CutOut, comprising a first electrical connection rod; a second electrical connection rod; a first contact; a second contact; and a fuse wire; wherein the first contact is mounted to the first electrical connection rod; wherein the second contact is mounted to the second electrical connection rod; wherein when a current below a threshold levels flows through the vacuum-based fuse—CutOut or no current flows through the vacuum-based fuse—CutOut the vacuum-based fuse—CutOut is configured to hold the first contact a fixed distance from the second contact and the fuse wire is configured to electrical connect the first electrical connection rod to the second electrical connection rod; and wherein when a current at or above the threshold flows through the vacuum-based fuse—CutOut the fuse wire is configured to electrically disconnect the first electrical connection rod from the second electrical connection rod.

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 method for operating a drive of a vacuum interrupter in opening modus includes: dividing an opening movement of at least one movable contact into serial phases, an opening phase, and an isolating phase, driven in at least two different velocities. In the opening phase a velocity of the opening movement is lower than in the isolating phase.
