20100220417 | COMPACT DISCONNECTOR CIRCUIT-BREAKER FOR AN ALTERNATOR - An alternator disconnector circuit-breaker of the invention presents a compact structure. The axes of opening/closure of the change-over first switch ( | 09-02-2010 |
20100220418 | ALTERNATOR CIRCUIT-BREAKER WITH AN INSERTED RESISTANCE - An alternator disconnector circuit-breaker of the invention presents a resistance ( | 09-02-2010 |
20120199322 | COOLING METHOD AND DEVICE FOR COOLING A MEDIUM-VOLTAGE ELECTRICAL INSTALLATION IN A PROTECTIVE SHEATH - A device including a phase-change heat-transfer fluid cooling mechanism to cool a sheath in which is placed switchgear such as a circuit breaker. An evaporator is thus created which is connected to condensers that are placed on a roof of the sheath. The device can be for application to a medium-voltage high-current electrical installation. The device requires little maintenance and only consumes a reduced amount of energy, or even no energy. | 08-09-2012 |
20120204590 | COOLING DEVICE FOR COOLING MEDIUM-VOLTAGE SWITCHGEAR BY MEANS OF LIVE HEAT PIPES - A cooling device including an evaporator operating with a phase-change heat-transfer fluid surrounding electrical switchgear operating at high voltage and connected to one or more condensers placed on a roof of a sheath in which the electrical switchgear is placed. The condensers are supported in this location by insulating elements that include side partitions that are to the side relative to a box, placed above the sheath and/or a central portion of the roof of the sheath. The cooling device consumes very little energy and does not require an electrically insulated cooling system to be designed and can be used, for example, for application to medium-voltage generator circuit breakers. | 08-16-2012 |
20120205074 | COOLING DEVICE FOR COOLING MEDIUM-VOLTAGE APPARATUS USING INSULATED HEAT PIPES - The cooling device is suitable for fitting to existing installations, without redesigning them. It consists in using heat pipes ( | 08-16-2012 |
20120206863 | COOLING METHOD FOR COOLING MEDIUM-VOLTAGE ELECTRICAL SWITCHGEAR USING INTEGRATED HEAT PIPES, AND A SYSTEM USING SAID METHOD - The method of the invention makes it possible to cool electrical switchgear operating at medium voltage and high current, such as a circuit breaker. The method consists in inserting serially two heat pipes ( | 08-16-2012 |
20150014279 | Device For Protection Against Particles Generated By An Electric Switching Arc - A protection device for providing protection against the particles generated by an electric arc when a first electrically conductive part and a second electrically conductive part of an electrical connection unit are separated from each other, the protection device including at least one protection element disposed in the proximity of the place at which the first part and the second part separate in order to form a shield against the particles. | 01-15-2015 |
