Patent number: 8658932Abstract: A device for detecting vacuum loss in a vacuum breaking apparatus that includes an enclosure having a first part at least partially of insulating material, closed at its opposite ends by end-plates, and housing fixed and mobile electrodes. A second part of the enclosure is insulating material at least partially around the first part, this second part is an over-molding of electrically grounded conductive shielding at least a part of its outer surface. This first strip of over-molding faces both the first part and one of the electrodes, thereby providing two capacitances in series, namely, a vacuum capacitance between the electrode and the inner surface of the first part, and a solid capacitance between the inner surface of the first part and the first strip, and means for measuring change of current value in the first strip, which corresponds to a vacuum loss inside a vacuum breaking apparatus.Type: GrantFiled: November 14, 2011Date of Patent: February 25, 2014Assignee: Schneider Electric Industries SASInventors: Hans Schellekens, Serge Olive, Jean Pierre Gauthier

Patent number: 6762388Abstract: The present invention relates to a vacuum cartridge for an electrical protection apparatus such as a switch or a circuit breaker, said cartridge comprising an enclosure of substantially cylindrical shape closed by two end plates, two contacts extending axially inside the enclosure, at least one whereof, called the movable contact, is connected to an operating mechanism and is mounted sliding between a closed position of the contacts enabling the current to flow and a position wherein the contacts are separated and form an electric arc between them, and a means for producing an axial magnetic field in the arc formation zone. This cartridge comprises at least one conducting shield fitted around the periphery of at least one of the contacts, said shield being shaped and arranged in such a way as to withstand the electric field arising from the recovery voltage imposed by the power system after breaking and to thus considerably reduce the electric field at the edge of said contact.Type: GrantFiled: June 10, 2003Date of Patent: July 13, 2004Assignee: Schneider Electric Industries SASInventors: Hans Schellekens, Serge Olive

Patent number: 6541726Abstract: A vacuum cartridge, in particular for an electrical protection apparatus such as a switch or circuit breaker, comprising an enclosure of appreciably cylindrical shape closed by two end-plates, two contacts extending axially inside the enclosure, at least one of which contacts called the movable contact is connected to an operating mechanism and is slidingly mounted between a closed position of the contacts corresponding to a rest position of the apparatus and a position in which the arcing contacts are separated and form an electric arc between them, separation of the contacts resulting in breaking of the electrical circuit, and a means for producing an axial magnetic field for diffusion of the arc in the arc formation area. The cartridge comprises means for speeding up cooling of the contact material in liquid form flowing on the contact surface of said arcing contacts during breaking.Type: GrantFiled: April 10, 2001Date of Patent: April 1, 2003Assignee: Schneider Electric Industries SAInventors: Hans Schellekens, Denis Giraud, Serge Olive, Christophe Arnaud

Patent number: 4737607Abstract: An electrical circuit breaker with self-expansion and rotating arc insulated with SF6 comprises a fixed arcing contact secured to the front face of a magnetic blow-out coil.An electrode is electrically insulated from the fixed arcing contact and covers the front face being connected to the opposite end of the coil by a branch circuit. The electrode is arranged to pick up a fraction of the arcing current, so that the magnetic field generated in the breaking zone by the coil remains appreciably constant when the value of the short-circuit current exceeds a predetermined threshold.Type: GrantFiled: March 18, 1987Date of Patent: April 12, 1988Assignee: Merlin GerinInventors: Georges Bernard, Pierre Leclercq, Serge Olive

Patent number: 4424428Abstract: The invention concerns a rotating arc switch using a permanent magnet (38) arc blow-out. The permanent magnet is housed inside the fixed contact (16) and is thermally and electrically isolated from it by an insulating layer (46). The permanent magnet (38) is placed against the annular contact (36) surface, very close to the breaking zone, and has a cavity (40) opposite the central opening of the annular surface (36). The magnetic blow-out is combined with a pneumatic blow out by escape of the warmed gases towards an expansion chamber (36).Type: GrantFiled: April 2, 1981Date of Patent: January 3, 1984Assignee: Merlin Gerin S.A.Inventors: Georges Bernard, Serge Olive, Francesco Scarponi
