Abstract
A compression sealing gasket having a main body of general planar extension, or extending in a plane, including an inner side and an outer side, and end faces, which delimit the gasket along an axis perpendicular to the plane, and connect the inner side and the outer side, made of an elastomer material, the main body having a first extension, along the axis, at least one of the inner side and the outer side being provided with a lip which has a second extension, along the axis perpendicular to the plane, less than the first extension.
Claims15
A sealing system comprising two components of a gas insulated portion of a high or medium voltage apparatus, the gas insulated portion forming part of a switch, or of a circuit-breaker, or of a disconnector, or of a transformer, or of a surge-arresters, or of a gas-insulated line, in which each of the components comprises an end or assembly face that faces the end or assembly face of the other component, at least one of the assembly faces comprising at least one recess and wherein at least one compression sealing gasket is at least partly arranged in the at least one recess and is compressed between the assembling faces of the components, the compression sealing gasket comprising a main body of general planar extension, or extending in a plane, comprising an inner side and an outer side, and end faces, which delimit the gasket along an axis perpendicular to the plane, and connect the inner side and the outer side, made of an elastomer material, the main body having a first extension, along the axis, at least one of the inner side and the outer side being provided with a lip which has a second extension, along the axis perpendicular to the plane, less than the first extension.
A sealing system comprising two components of a gas insulated portion of a high or medium voltage apparatus, the gas insulated portion:
- containing, or being intended to contain, a gas comprising at least:
- heptafluoroisobutyronitrile and/or heptafluoroisopropyl trifluoromethyl ketone (also named 2butanone, 1,1,1,3,4,4,4-heptafluoro-3-(trifluoromethyl)-(CAS No 756-12-7)), possibly mixed with a gas or a dilution gas comprising at least CO2 and/or O2 and/or N2 and/or an oxygenated compound;
- or to a gas comprising at least CO2 and/or O2 and/or N2 and/or an oxygenated compound and/or water vapor;
- and/or the gas insulated portion being surrounded, or being intended to be surrounded by an atmosphere containing some water and/or water vapor;
- in which each of the components comprises an end or assembly face that faces the end or assembly face of the other component, at least one of the assembly faces comprising at least one recess and wherein at least one compression sealing gasket is at least partly arranged in the at least one recess and is compressed between the assembling faces of the components, the compression sealing gasket comprising a main body of general planar extension, or extending in a plane, comprising an inner side and an outer side, and end faces, which delimit the gasket along an axis perpendicular to the plane, and connect the inner side and the outer side, made of an elastomer material, the main body having a first extension, along the axis, at least one of the inner side and the outer side being provided with a lip which has a second extension, along the axis perpendicular to the plane, less than the first extension.
