Abstract
Dielectric gas mixture including a binary pair of gases with electric strengths in uniform or quasi-uniform fields which are higher than that for either component of the gases alone. Such binary pairs include (a) SF.sub.6 and CF.sub.3 CFCF.sub.2, (b) SO.sub.2 and CF.sub.3 CFCF.sub.2, and (c) SO.sub.2 and SF.sub.6.
Claims8
A dielectric gas mixture comprising a binary pair of gases selected from the group consisting of (a) SF.sub.6 and CF.sub.3 CFCF.sub.2, (b) SO.sub.2 and CF.sub.3 CFCF.sub.2, and (c) SO.sub.2 and SF.sub.6.
A method for insulating the conductor of an electrical apparatus comprising the step of disposing a dielectric gas mixture adjacent said conductor while it carries an electric current, said gas mixture comprising a binary pair of gases selected from the group consisting of (a) SF.sub.6 and CF.sub.3 CFCF.sub.2, (b) SO.sub.2 and CF.sub.3 CFCF.sub.2, and (c) SO.sub.2 and SF.sub.6.
Electric equipment comprising an electrical conductor and a contained dielectric gas mixture adjacent said conductor, said gas mixture comprising a binary pair of gases selected from the group consisting of (a) SF.sub.6 and CF.sub.3 CFCF.sub.2, (b) SO.sub.2 and CF.sub.3 CFCF.sub.2, and (c) SO.sub.2 and SF.sub.6.
