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.
Claims12
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 is defined by a portion of the housing for gas in the GIS system having a first thickness, different from a second thickness of a remaining portion of the housing for gas in the GIS system adjacent the pressure relief mechanism, the first thickness being less than the second thickness and the first thickness being uniform throughout the pressure relief mechanism;
- and
- wherein the pressure relief mechanism is configured to rupture at predetermined overpressure conditions to vent bi-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 for the GIS system having a first thickness, different from a second thickness of a remaining portion of the housing of the GIS system adjacent the pressure relief mechanism, the first thickness being less than the second thickness and the first thickness being uniform throughout the pressure relief mechanism;
- wherein the pressure relief mechanism is 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;
- and
- wherein the pressure relief mechanism is integrated with the housing such that the pressure relief mechanism is not installed onto or into the housing.
A gas insulated switchgear (GIS) comprising:
- a gas filled housing including a pressure relief mechanism incorporated into the housing,
- wherein the pressure relief mechanism is defined by a portion of the gas filled housing for the GIS having a first thickness, different from a second thickness of a remaining portion of the gas filled housing of the GIS adjacent the pressure relief mechanism, the first thickness being less than the second thickness and the first thickness being uniform throughout the pressure relief mechanism;
- 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.
