Abstract: PROBLEM TO BE SOLVED: To provide a disconnector which has a high dielectric strength, and can be simply and inexpensively manufactured in small size. SOLUTION: The disconnector provides two insulated contacts (2) disposed in a conductive capsule container (1) filled with essentially insulating gas, and an insulated finger (3) movable between the insulated contacts. An insulating coating (7) is formed in the capsule container and has a protrusion (8) protruding toward the inner. The insulating coating prevents a spark generated in the disconnector from flashing over the capsule container (1) when the disconnector is opened. Another protrusion (9) prevents the spark from propagating toward the insulated contacts (2).

Abstract: The disconnector essentially comprises two isolating contacts (2), which are arranged in electrically conductive encapsulation (1) filled with insulating gas, and an isolating contact finger (3) arranged such that it can be moved between them. An insulation coating (7) is applied to the inside of the encapsulation (1) and has projections (8) pointing inward.The insulation coating prevents a disconnector spark (5), whose production cannot be avoided when the disconnector is opened, from flashing over onto the encapsulation (1). Furthermore, additional projections (9) prevent the spark from propagating in the direction of the isolating contacts (2).
