Abstract: Disclosed herein is a circuit breaker having a closing resistor, which is capable of preventing impact caused when the circuit breaker is opened and closed from being transferred to peripheral structures. The circuit breaker having a closing resistor includes a fixed part having a fixed contact, a movable part having a movable contact, a closing resistor unit connected to the fixed part and having a closing resistor unit contact, a closing resistor movable part connected to the movable part and having a closing resistor movable contact, and a support structure slidably coupled to the closing resistor unit in a direction parallel to a movement direction of the closing resistor movable part, thereby enabling impact and vibration applied to the closing resistor unit to be absorbed by the support structure.

Abstract: A portable load-breaking and pickup apparatus for handling a load associated with a power distribution system is disclosed. The apparatus includes first and second spaced-apart connectors electrically connected by a load break assembly. The load break assembly includes first and second outer contacts configured for mating engagement and configured to provide a low-resistance path between the first and second connectors, and first and second inner contacts configured for mating engagement and configured to provide a high-resistance path between the first and second connectors. The load break assembly transitions from an open position to a closed position in two stages. The two stages include closing the high-resistance path prior to closing the low-resistance path, and closing the low-resistance path after the high-resistance path has been closed.

Abstract: A commutating circuit breaker that progressively inserts increasing resistance into a circuit via physical motion of a shuttle that is linked into the circuit by at least one set of sliding electrical contacts on the shuttle 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. At no point are the sliding stator electrodes separated from the matching stationary stator electrodes so as to generate a powerful arc, which minimizes damage to the sliding stator electrodes. Instead, the current is commutated from one resistive path to the next with small enough changes in resistance at each step that arcing is 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.

Abstract: The invention relates to a tap changer for the interruption-free switchover between winding taps of a tap-changing transformer. Furthermore, the present invention relates to a novel vacuum interrupter which is particularly suitable for such a tap changer. The tap changer according to the invention is based on the general concept of combining in each case one main contact (V1) and one mechanical switching means (U1), connected in series therewith, of a first load branch and an additional resistive contact (V3) of a second load branch in only a single vacuum interrupter (1) with a common housing (5). The vacuum interrupter (1) according to the invention is furthermore based on the general inventive concept of replacing the functionalities of two required vacuum interrupters in accordance with the prior art and an additional mechanical switching means with a single vacuum interrupter (1) according to the invention by virtue of combining the design of a vacuum interrupter (1) with a plurality of moveable contact systems (I, II, III), which are arranged in separate vacuum
