Latest Patents

One of his latest patents is a vacuum interrupter with a slow opening solenoid core inside to shorten the length of the conductor assembly. This innovative 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. 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. This magnetization attracts the iron core, causing the movable conductor to separate from the stationary conductor.

Another significant patent is for a multi-part moving shaft assembly for an ultra-high-speed actuator used in a hybrid circuit breaker. This invention decreases separable contact opening time by reducing the number of components that must travel during the initial stage of an opening stroke to achieve an initial gap between the separable contacts. The components that must travel to open the separable contacts are included in only some portions of the movable assembly, rather than all portions. In one embodiment, a split switch shaft coupled to a movable conductor includes a head shaft coupled to a tail shaft using a sliding pin, enabling the head shaft to travel an initial distance while the tail shaft remains stationary, thus achieving an initial gap between the contacts. In another embodiment, the movable conductor assembly is coupled to hydraulics, allowing it to travel an initial distance at high speeds before damping by the hydraulic fluid.
