Abstract
Housings for gas in a gas insulated switchgear (GIS) system is provided. The housing includes a pressure relief mechanism incorporated into the housing. The pressure relief mechanism includes a portion of the housing having a first thickness, different from a second thickness of a remaining portion of the housing, the first thickness being less than the second thickness. The pressure relief mechanism is configured to rupture at predetermined overpressure conditions to vent bi-products of an arc fault in the GIS system.
Claims20
A housing for gas in a gas insulated switchgear (GIS) system, the housing comprising a pressure relief mechanism incorporated into the housing,
- wherein the pressure relief mechanism includes a portion of the housing having a first thickness, different from a second thickness of a remaining portion of the housing, the first thickness being less than the second thickness;
- and,
- wherein the pressure relief mechanism is configured to rupture at predetermined overpressure conditions to vent hi-products of an arc fault in the GIS system.
A pressure relief mechanism for a housing of a gas-filled switchgear in a gas insulated switchgear (GIS) system, the pressure relief mechanism comprising a portion of the housing having a first thickness, different from a second thickness of a remaining portion of the housing, the first thickness being less than the second thickness and the pressure relief mechanism being configured to rupture at predetermined overpressure conditions to vent bi-products of an arc fault in the GIS system,
- wherein the pressure relief mechanism is present on one of an interior and an exterior of the housing.
(canceled).
A gas insulated switchgear (GIS) comprising:
- a gas filled housing including a pressure relief mechanism incorporated into the housing,
- wherein the pressure relief mechanism includes a portion of the housing having a first thickness, different from a second thickness of a remaining portion of the housing, the first thickness being less than the second thickness;
- and
- wherein the pressure relief mechanism is configured to rupture at predetermined overpressure conditions to vent bi-products of an arc fault in a GIS system.
