    摘要: A high tension circuit-breaker has an insulating case filled with a dielectric gas such as SF.sub.6. A high capacitance capacitor and at least a varistor are electrically interconnected in parallel and are connected to a first terminal. The capacitor and varistor are associated with an insertion mechanism which momentarily inserts the capacitor and varistor in parallel with the arcing contacts during circuit-breaker disengagement or engagement. The insulating case is extended by at least one conductive case housing both the capacitor and at least part of the varistor.

    摘要: A high-voltage circuit-breaker has an interrupting chamber comprising a gas-tight cylindrical casing filled with a gas having good insulative properties such as sulfur hexafluoride. The casing contains a fixed permanent contact, a fixed arc contact and a mobile assembly comprising permanent contacts and arc contacts and associated with a gas blast assembly. The chamber also contains a carbon-based resistor having a resistance of approximately 500 ohms connected in parallel with the circuit-breaker contacts when the arc contacts are opened by an auxiliary switch. This resistor is connected in series with an arrangement of varistors, the resulting combination being disposed inside the casing and connected in series with the auxiliary switch. Opening of the auxiliary switch is effected by opening of the circuit-breaker. The volume of the resistor is greater than that of the arrangement of varistors by a factor of at least five.

    摘要: The gas-insulated line comprises a conductor (1A) disposed inside a case (3A) filled with a dielectric gas under pressure. A power capacitor (5) is electrically connected to the conductor while being disposed inside a compartment (3P) secured to the case (3A) and filled with a dielectric gas under pressure. The dielectric gas present in the compartment (3P) provides electrical insulation for the compartment relative to the power capacitor (5). In this way, electrical insulation of the gas-insulated line between the conductor (1A) and the case (3A) is maintained inside the compartment (3P) in which the power capacitor (5) and the conductor (1A) are electrically interconnected. This results in the gas-insulated line of the invention retaining small bulk and the ability to be used on the ground or buried.
