Latest Patents

Osawa holds a patent for a "Method of current interruption using puffer type gas circuit breaker with combined-action of cylinder and piston." This invention features a puffer type gas circuit breaker that incorporates a piston connected to a center shaft via a link mechanism. During the initial stage of the interruption operation, the link mechanism drives both the puffer cylinder and the piston in the interruption direction while maintaining a nearly constant distance between them. This design ensures that even if a pressure rise occurs in the compression chamber due to the heat of an arc generated during the opening between the fixed and movable arc contacts, it does not counteract the operator's actions. At the final stage of the interruption operation, where the fixed arc contact is removed from the throat of an insulating nozzle, the link mechanism drives the piston in an almost stopped status.
