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： A power circuit breaker has a housing defining a first passage and a cross passage through the housing. A bus bar extends through the cross passage and is configured to transmit electric power and/or break transmission of the electric power through the housing. The bus bar includes at least an input section, a coin or center section, and an output section that are separable from each other. The housing aligns a solenoid piston within the first passage of the housing. The solenoid has a piston with two opposite ends, and one of the ends operates as a plunger to separate the sections of the bus bar when the solenoid is actuated. The plunger moves the coin or center section of the bus bar out of contact with the input section and the output section of the bus bar to break electrical transmission across the bus bar.

摘要： An electromagnetic repulsion actuator for a circuit breaker is provided. The actuator can include a housing; a first fixed electrode having therein an operating space open at both sides; a pair of movable electrodes capable of reciprocally moving and being electrically connected to the first fixed electrode; second fixed electrodes selectively contacting the pair of movable electrodes to be electrically connected thereto, thereby transferring power supplied from a first side to a second side; and actuating coils selectively moving the movable electrodes in a direction of being separated from the second fixed electrodes by generating electromagnetic force from induced current. In the present invention as above, the structure of a circuit breaker is simplified and moving speeds of the movable electrodes are increased since the movable electrodes move by using induced current generated by a close coil and open coils to perform an open operation.

摘要： A commutating circuit breaker that works by progressively inserting increasing resistance into a circuit. This is done via physical motion of a shuttle that is linked into the circuit by at least one set of sliding electrical contacts on the shuttle (“shuttle electrodes”) that connect the power through the moving shuttle to a sequence of different resistive paths with increasing resistance; the motion of the shuttle can be either linear or rotary. A feature of the commutating circuit breaker is that at no point are the shuttle electrodes separated from the matching stationary stator electrodes so as to generate a powerful arc, which minimizes damage to the electrodes. Instead, the current is commutated from one resistive path to the next with small enough changes in resistance at each step that arcing can be suppressed. The variable resistance can either be within the moving shuttle, or the shuttle can comprise a commutating shuttle that moves the current over a series of stationary resistors. In either case, a “soft” opening of the circuit can be accomplished, with low switching transients, provided that the maximum step change of resistance is limited until the current is nearly extinguished. Commutating circuit breakers work equally well for DC or AC power.
