Title: Innovations of Jacques Olifant
Introduction
Jacques Olifant is a notable inventor based in Nanterre, France. He has made significant contributions to the field of electrical devices, holding a total of 11 patents. His work focuses on enhancing the functionality and safety of electrical systems.
Latest Patents
One of his latest patents is an electrical device with double AC breaking contacts. This device features two breaking areas formed at each side of a contact bridge carrying main contacts. These contacts can be separated from fixed contacts located in the breaking areas, which are fixed to main conductors. The main conductors have shaped extensions in the break areas that cooperate with shaped extensions associated with arc collection parts positioned nearby. The design encourages a specific direction of arc migration relative to arcs created when the movable contacts are separated from the fixed contacts. Additionally, magnetic fields are utilized in each breaking area to control arc migration.
Another significant patent is the contactor-circuit breaker. This device houses power poles and an electromagnet that activates the moving contacts in contactor mode. It includes a fixed magnetic circuit, a moving magnetic circuit, and a coil whose electric supply is controlled by a switch. The device also features at least one current sensor that controls a releasing electromagnet. Notably, the activating and releasing electromagnets are constituted by a single electromagnet, which enhances efficiency.
