摘要: A switching device for fast disconnection of short-circuit currents includes a switching bridge with a movable contacting element and a fixed contacting element. The switching bridge is operable in a closed state, in which the movable contacting element is in contact with the fixed contacting element, and an open state, in which the movable contacting element is spaced apart from the fixed contacting element. The switching device further includes an electromagnetic switching drive with a coil for generating a magnetic field and a magnet anchor, a guide sleeve to guide the movement of the magnet anchor in the magnetic field of the coil, a pyrotechnic propellant charge located in the cavity, and a supporting device for supporting the guide sleeve. The magnet anchor is arranged within the guide sleeve such that a cavity is formed below the magnet anchor.

摘要: The present disclosure discloses a liquid arc extinguish chamber for direct current breaking. The liquid arc extinguish chamber for direct current breaking includes a cavity, a fixed contact and a moving contact. A liquid medium is sealed in the cavity. The fixed contact is hermetically fixed in the cavity. One end of the fixed contact is fixed in the cavity, and the other end of the fixed contact is connected with an outlet terminal A1. The moving contact is movably sealed in the cavity. One end of the moving contact may adjacently abut against or be in contact with the fixed contact, and the other end of the moving contact is connected with an outlet terminal A2.

摘要: A circuit breaker, comprising an enclosure comprising: —at least two arcing contacts that are movable axially relative to each other, between an open position of the circuit breaker in which the arcing contacts are separated from each other and a closed position of the circuit breaker in which the arcing contacts are in contact with each other; and —a gas inlet configured to blow an arc-control gas in order to interrupt an electric arc that is likely to form during movement of the arcing contacts from the closed position to the open position of the circuit breaker, wherein the arc-control gas comprises at least 80% of carbon dioxide; wherein the enclosure further comprises a catalytic material, which converts carbon monoxide that forms after ionization of the carbon dioxide during arcing, into carbon dioxide, said catalytic material comprising ceria and a precious metal.

摘要: The present invention relates to a device for interrupting non-short circuit currents only, and in particular relates to a disconnector, more particularly high voltage disconnector, or to an earthing switch, more particularly make-proof earthing switch, and further relates to a low voltage circuit breaker. The device comprises at least two contacts movable in relation to each other between a closed state and an open state and defining an arcing region, in which an arc is generated during a current interrupting operation and in which an arc-quenching medium comprising an organofluorine compound is present. According to the application, a counter-arcing component is allocated to the arcing region, the counter-arcing component being designed for counteracting the generation of an arc and/or being designed for supporting the extinction of an arc.

摘要: A circuit breaker system has an SF6 tank having a wall, and an SF6 heating system. The SF6 heating system includes a heater disposed externally of the tank, and a radiator disposed on the wall inside the SF6 tank. The radiator is thermally coupled to the heater via the wall. The heating system is constructed to conduct heat from the heater through the wall to the radiator. The radiator is constructed to radiate the heat to the SF6 in the tank. A circuit breaker system has an SF6 tank having a wall, and a particle trap. The particle trap has a spar extending radially inward from the wall and a wing extending outward from each side of the spar. Each wing is spaced apart from the wall and forms a region having no electric field at the bottom of the tank adjacent the spar.

摘要: The conduction breaking device includes a conductive body, a fixed blade, an arc-extinguishing chamber, a gas generator, a cutting member, and a cutting delaying portion. The fixed blade and the arc-extinguishing chamber are located on one side of the cuttable portion with respect to a thickness direction of the cuttable portion in the conductive body. The gas generator is located on the opposite side of the cuttable portion with respect to the thickness direction. The cutting member is arranged between the cuttable portion and the gas generator and includes a movable blade. The cutting delaying portion is provided at the movable blade and configured to allow a part of an area of the cuttable portion that is, in the width direction, closer to the center than the edges are to the center to be cut after the other parts are cut.
