    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.

    摘要: The present invention provides a simple, reliable, comprehensive electrical phase and amplitude fault detection and response system. The system includes means for detecting any of various electrical faults, such as impermissibly low voltage levels, impermissibly high voltage levels, phase dropouts, single-phasing, phase reversals, and/or total power loss. Further, the invention provides both fault detection and response customized to the plant equipment, providing power cut-off an appropriate time after a given fault is detected, and preventing premature power restoration when the line power has not been fully returned to normal. The system provides the fault detection and response functions without the need for electrical power of its own, avoiding dependence on line voltage, batteries or back-up generators. This functioning independent of the presence of electrical power is enabled through use of a pneumatic arrangement for interrupting power to plant equipment.

    摘要: A power circuit breaker has a novel trip valve on the pneumatic operating mechanism for reducing air consumption of the breaker pneumatic operating mechanism. The novel trip valve includes the addition of a valve stem extension to the trip valve shaft disposed in a sliding fit with an exhaust port to the trip valve actuating cylinder which together provide for quick elimination of compressed air from the trip valve actuating cylinder at a predetermined time during the operation of the breaker mechanism. Positive positioning of the breaker contact and rapid closing of the trip valve at a predetermined time is effectuated, thereby reducing air consumption while providing a fail-safe air cushion to the driving piston of the pneumatic mechanism to insure positive positioning of the breaker contacts.

    摘要: A step-switching arrangement for changing the taps on a transformer winding without interrupting the flow of current from the winding to a load line includes a precontact switch and a current-limiting resistance connected in a series circuit extending from the transformer tap changing contacts to the load line, this circuit being paralleled by a circuit containing a changeover switch and vacuum switch connected in series and also extending from the tap-changing contacts to the load line. A circulating current through the switches and resistance and part of the transformer winding occurs during a change in taps, and this circulating current is interrupted by opening the contacts of the vacuum switch. All of the switches are actuated by hydraulic motors of the linear type, the motors being supplied from hydraulic pumps of the linear type which are operated in synchronism with the tap-changing mechanism so as to obtain the necessary operating sequence for the various switches in changing over from one tap to another.

    摘要: An electrical switching system of the type which includes a main power switching point, an auxiliary switching point connected in parallel with the main switching point through a secondary circuit which includes a series resistance, and a voltageisolating switching point connected in series with the main switching point. Upon application of a switching-on order, current is caused to flow only through the secondary path containing the series-connected auxiliary switching point and resistance, and also the voltage-isolating switching point which is now closed in order to test the condition of the circuit. If the current flow is abnormally high, the auxiliary switching point is opened and the voltage-isolating switching point is reopened. Thus, there is no current flow through the main power switching point during the test period and this main switching point closes to complete the switching-on order only in the event that the current flow in the circuit is normal.
