    摘要： Disclosed is a gas insulated switchgear constituted such that electrical contacts are placed inside a sealed vessel filled with an arc extinguishing gas, and when electrical current passes, the electrical contacts are held in contact and pass electricity, and when the current is interrupted, the electrical contacts are separated and an arc discharge is produced in the arc extinguishing gas, and the current is interrupted by extinguishing this arc. The arc extinguishing gas is a mixed gas, the main constituents of which are N2 gas and CH4 gas, and the CH4 content is at least 30%. Alternatively, the arc extinguishing gas is a mixed gas, the main constituents of which are CO2 gas and CH4 gas, and the CH4 content is at least 5%.

    摘要： This electrical switchgear has an interrupting chamber enclosing an interrupting gas (G) substantially devoid of SF6 and of CF4, and a first arcing contact (10) and a second arcing contact (18), the two arcing contacts moving causes an electric arc (26) to strike, while at least one irradiation wall (22) is provided that is suitable for being reached by the electric arc. At least two component materials that are part of at least one element selected from the interrupting gas, the first and second arcing contacts, and the or each irradiation wall, are suitable for decomposing under the effect of the electric arc, so as to form decomposed species (e1, e2) suitable for combining in the interrupting chamber, in order to form at least one new gaseous species (G1), before the electric arc is extinguished, the dielectric properties of said at least one new gaseous species being superior to the dielectric properties of said interrupting gas (G).

    摘要： An electrical switch for efficient, high continuous current carrying operation, with at least one movable contact for effecting current interruption. The ambient pressure within the volume defined by the electrical switch body is maintained at or is reducible during contact opening to between 10.sup.-1 to 10.sup.2 Torr to minimize contact erosion. A preferred electrical switch is a hermetically sealed, low voltage d.c., device for shunting an electrolyte cell. The sealed switch module has a reduced pressure atmosphere of inert fill gas at a pressure of from 10.sup.-1 to 10.sup.2 Torr.

    摘要： Carbon formation on voltage breakdown and sparking, and consequent carbon deposits on insulators and other surfaces, is suppressed in dielectric gases of halogenated alkanes by adding SF.sub.6 and/or CO.sub.2 to the halogenated alkane to form a gaseous dielectric mixture. Moreover, certain of the gaseous dielectric mixtures evidence unexpectedly high dielectric breakdown voltages. The gaseous dielectric mixtures are useful in high voltage coaxial lines, in transformers, in minisubstations, and the like.
