Abstract
An arc flash management system including a cabinet having multiple walls surrounding electrical equipment capable of producing arc flash, at least one aperture within one of the walls, and an arc exhaust attachment emanating from at least one of the apertures for directing possible arc flash away from the cabinet.
Claims20
An arc flash management system, comprising:
- a cabinet having multiple walls, the cabinet surrounding electrical equipment capable of producing an arc flash, wherein at least one wall of the cabinet comprises at least one aperture;
- an arc exhaust attachment emanating from the at least one aperture, the arc exhaust attachment configured to direct the arc flash, when produced, away from the cabinet;
- and
- a cap installed in the arc exhaust attachment, the cap configured to prevent pollutants from entering the cabinet and to indicate if the arc flash has occurred.
1 more element
An apparatus for directing an arc flash comprising:
- an arc exhaust attachment including a threadable coupling for coupling the arc exhaust attachment to an electrical cabinet;
- a plurality of filters located within the arc exhaust attachment, the plurality of filters configured to prevent pollutants from entering the electrical cabinet and to diffuse arc flashes emanating from the electrical cabinet;
- and
- a cap installed in the arc exhaust attachment, the cap configured to prevent pollutants from entering the cabinet and to indicate if the arc flash has occurred,
- wherein the plurality of filters include a metal material, and
- wherein the arc exhaust attachment includes a first portion directed in a first direction, and a second portion directed in a second direction, wherein the first direction is perpendicular to the second direction.
3 more elements
A method of controlling an arc flash comprising:
- installing an arc exhaust attachment within an aperture of a cabinet surrounding electrical equipment capable of producing the arc flash;
- operating the electrical equipment in a way that produces the arc flash;
- dissipating energy stored in the arc flash by a filter housed within the arc exhaust attachment;
- and
- moving, by the arc flash, a cap installed in the arc exhaust attachment from a first position to a second position to indicate if the arc flash has occurred.
2 more elements
An arc flash management system, comprising:
- a cabinet having multiple walls, the cabinet surrounding electrical equipment capable of producing an arc flash, wherein at least one wall of the cabinet comprises at least one aperture;
- an arc exhaust attachment emanating from the at least one aperture for directing the arc flash, when produced, away from the cabinet;
- and
- a plurality of filters arranged in series and housed within the arc exhaust attachment, the plurality of filters configured to prevent pollutants from entering the cabinet and to diffuse arc flashes,
- wherein the plurality of filters progress from more coarse to more fine in a direction from the aperture to an outlet of the arc exhaust attachment.
2 more elements
An arc flash management system, comprising:
- a cabinet having multiple walls, the cabinet surrounding electrical equipment capable of producing an arc flash, wherein at least one wall of the cabinet comprises at least one aperture;
- and
- an arc exhaust attachment emanating from the at least one aperture for directing the arc flash, when produced, away from the cabinet,
- wherein the arc exhaust attachment includes a first end within the cabinet, and a second end outside of the cabinet, and wherein the second end is open.
