Abstract: Embodiments described herein relate generally to a current interrupt device (CID) including a frangible bulb that is configured to be thermally triggered. In some embodiments, the CID includes a breaking contact electrically coupled to a fixed contact and held in electrical contact by the frangible bulb. In some embodiments, the frangible bulb is configured to break at a temperature threshold. In some embodiments, the breaking contact is configured to bend, rotate and/or otherwise deform about a hinge point in order to become electrically disconnected from the fixed contact when the frangible bulb breaks. In some embodiments, opening the electrical circuit between the breaking contact and the fixed contact may prevent overcharging, overvoltage conditions, overcurrent conditions, thermal runaway, and/or other catastrophic failure events.

Abstract: A bypass switch includes: a casing; a vacuum interrupter disposed inside the casing, the vacuum interrupter being disposed such that a movable contact is movable to a fixed contact; a first fixing bus-bar fixed to the casing; a second fixing bus-bar fixed to the casing to be spaced apart from the first fixing bus-bar; a moving pusher connected to the movable contact; a drive source installed in the casing, the drive source pushing the moving pusher to a position at which the movable contact and the fixed contact are contacted with each other; and a multi-contactor disposed to be contacted with the moving pusher. Accordingly, the moving pusher can rapidly contact the movable contact with the fixed contact. Further, the moving pusher can be moved with a small external force. Thus, it is possible to minimize the size of the drive source and the power used in the drive source.

Abstract: A conduction breaking device is provided that uses gas from a gas generator to move a cutter block in the thickness direction of a cuttable portion, thereby cutting the cuttable portion between the moving cutter block and a cutting edge portion of a cutting chamber. The cutter block is attached to the cuttable portion such that, before generation of gas by the gas generator, a part of the cutter block is located in the cutting chamber and at a position close to the cutting edge portion in a direction along the surface of the cuttable portion.

Abstract: A switchgear includes a switching device, which is driven by a propellant chemical charge or fast acting switch. The switchgear includes a current or fault current detection unit, and an optical sensor unit for light arc or fault light arc detection, without the need of having an auxiliary voltage applied. In order to reduce the closing time of an earthing switch, the electrical circuit of an inductive current detection unit is electrically connected in series with a light sensing switching path, and a current signal directly ignites the propellant chemical charge or fast acting switch by using a limited electronic device.
