Abstract
A self-pressurized arc diverter includes a vessel configured to enclose a fusible member disposed in a conductor and a pressure-activated arc diverter. The pressure-activated arc diverter is configured to provide access to a preferred arc path when actuated by pressure in the vessel caused by an arc that is created when the fusible member opens.
Claims16
An arc resistant apparatus for diverting an uncontrolled arc fault, said arc resistant apparatus comprising:
- a vessel configured to enclose a fusible member spliced into a conductor;
- and a pressure-activated arc diverter configured to divert the uncontrolled arc fault and provide access to a preferred conductive arc path when actuated by pressure in the vessel caused by an arc that is created when the fusible member opens.
An apparatus comprising:
- a vessel configured to enclose a fusible member spliced into a conductor;
- and a pressure-activated arc diverter configured to provide access to a preferred conductive arc path when actuated by pressure in the vessel caused by an arc that is created when the fusible member opens;
- where the vessel comprises a cylindrical insulator tube having end caps through which the conductor passes,
- where the arc diverter comprises at least one slot in the cylindrical insulator tube and an insulating cover on the slot, where the cover is configured to be dislodged from the slot when the insulator tube becomes pressurized by the arc.
An arc resistant bus assembly for diverting an uncontrolled arc fault, said arc resistant bus assembly comprising:
- a bus;
- a preferred arc path component disposed proximate to the bus that provides a conductive ground path;
- a fusible link spliced into the bus, the fusible link configured to conduct a rated current of the bus and to vaporize in response to current above the rated current;
- a vessel enclosing the fusible link;
- and pressure-activated arc diverter configured to divert the uncontrolled arc fault and provide access to a preferred conductive arc path when actuated by pressure in the vessel caused by an arc that is created when the fusible link opens.
A bus assembly comprising:
- a bus;
- a preferred arc path component disposed proximate to the bus that provides a conductive ground path;
- a fusible link spliced into the bus, the fusible link configured to conduct a rated current of the bus and to vaporize in response to current above the rated current;
- a vessel enclosing the fusible link;
- and pressure-activated arc diverter configured to provide access to a preferred arc path when actuated by pressure in the vessel caused by an arc that is created when the fusible link opens,
- where the vessel comprises a cylindrical insulator tube having end caps through which the conductor passes,
- where the arc diverter comprises at least one slot in the insulator tube and an insulating cover on the slot, where the cover is configured to be dislodged from the slot when the insulator tube becomes pressurized by the arc.
