Title: The Innovations of Michel Berthet
Introduction
Michel Berthet is a notable inventor based in Gif sur Yvette, France. He has made significant contributions to the field of superconducting rotary electrical machines, holding a total of three patents. His work focuses on enhancing the efficiency and functionality of electrical machines through innovative designs.
Latest Patents
One of Berthet's latest patents is a current lead-in device for superconducting rotary electrical machines. This invention features a copper tube with a superconducting conductor fastened to a portion of its length. The entire length of the tube is equipped with copper cooling plates, which block the bore of the tube, allowing only a small hole for the passage of gaseous or hypercritical helium. This current lead is particularly applicable to the generation of electric power using cryoalternators. Another significant patent is for a rotating machine that utilizes a cooling fluid supplied by a rotating seal. This design ensures the circulation of a low-temperature cooling fluid through a closed loop circuit, employing a 'bayonet' type inner rotating seal with a very small radial gap. Longitudinal and radial piping within the rotor allows for internal circulation of the cooling fluid by thermal siphon effect, even in the absence of positive circulation.
Career Highlights
Throughout his career, Michel Berthet has worked with prominent companies such as Electricité De France - Service National and Société Générale De Constructions Électriques Et Mécaniques Alsthom S.A. His experience in these organizations has contributed to his expertise in electrical engineering and innovation.
