摘要： A diagnostic system for monitoring a mechanical trip mechanism of a circuit interrupter provides advanced diagnostics. The trip mechanism comprises a D-shaft that is actuated by the trip unit, an operating mechanism that is actuated by the D-shaft, and a pole shaft that is actuated by the operating mechanism to physically separate the separable contacts. During every opening operation, the diagnostic system determines how much time elapses between the D-shaft beginning to move to its open position and the pole shaft reaching its open position, in order to detect degradation of the trip mechanism as early as possible. This ensures that suboptimal performance is detected even if the trip mechanism is meeting the minimum requirements for acceptable performance. A user is notified once the performance has degraded to a level that is considered concerning before the trip mechanism fails altogether, saving significant time and resources and preventing more widespread damage.

摘要： An acoustic sensing system for detecting movement of an ultra-fast actuator in a hybrid circuit interrupter is disclosed. The system comprises a number of acoustic sensors structured to perform active or passive position sensing. For active sensing, the sensors emit sound waves toward a number of targeted portions of the actuator moving assembly and detect the positions of the targets based on acoustic signals reflected back to the sensors by the targets. For passive sensing, the sensors detect acoustic wavelets generated as a result of the moving assembly components moving during opening and closing operations. Acoustic signals can propagate through air or solids and thus the sensors can be mounted in a variety of locations within the circuit interrupter. Acoustic sensors are particularly well-suited for the circuit interrupter environment, as they are resilient to the environmental and external factors, such as dust, that can affect the performance of non-acoustic sensors.

摘要： A vacuum circuit interrupter integrates a solenoid core within the vacuum chamber for opening the separable contacts under non-fault conditions, using less space than if the solenoid were disposed in series with a high speed actuator. The interrupter includes an iron core, a steel seat with a trough, and a solenoid coil seated in the trough. The steel seat has a central opening through which the movable conductor passes. The iron core is fixed to a portion of the movable conductor so as to laterally surround the movable conductor within the vacuum chamber. The steel seat is structured such that, when the separable contacts are closed and a user provides an activating current to the solenoid coil, the magnetic field generated around the coil magnetizes the steel seat. When the steel seat is magnetized, it attracts the iron core, causing the movable conductor to separate from the stationary conductor.
