Title: Innovations by Jacques Joubert
Introduction
Jacques Joubert is a notable inventor based in Montbonnot, France. He has made significant contributions to the field of electrical engineering, particularly in the development of advanced switchgear apparatus. With a total of three patents to his name, Joubert's work reflects a commitment to innovation and safety in electrical systems.
Latest Patents
One of Joubert's latest patents is a very high-speed limiting electrical switchgear apparatus. This invention features a limiting circuit breaker that comprises two separable contacts and a mechanism with energy storage operated by an opening catch. The mechanism drives a movable cage between a closed position and an open position to perform the opening of the contacts. One of the contacts is movable with respect to the cage in the closed position and can thus take a separated position. A Thomson effect electromechanical actuator is provided to drive the movable contact to the separated position. A latch enables the movable contact to be held in the separated position. In the event of a fault requiring a very high-speed response, separation of the contacts is obtained by means of the Thomson effect actuator and is then confirmed by the opening of the mechanism. In other cases, only the mechanism operates to perform the opening.
Another significant patent by Joubert is an electrical switchgear apparatus comprising a plug-in circuit breaker and a device indicating the state of the circuit breaker. This apparatus includes a fixed frame, a circuit breaker movable in the fixed frame between a plugged-out position and a plugged-in position, and a reversible plug-in and plug-out mechanism of the circuit breaker. It also features movable means for detecting an indexed position of the mechanism or of the circuit breaker, linked to a first electrical switch, and a movable means for detecting an indexed position of the main contact means of the circuit breaker linked to a second electrical switch. This innovative design enhances the functionality and safety of electrical switchgear systems.
