METHOD FOR TREATING INTERNAL ARCS

摘要

Methods and systems for controlling and limiting the damage caused by arcs in electrical distribution equipment provide a cooling assembly that uses a filter or other porous substrate to absorb the energy from the arc byproducts. The filter-based cooling assembly may be used with a passive arc management device having a chamber sized and shaped to control and/or extinguish arcs and ventilation ports for expelling the arc byproducts into the cooling filter assembly. The filter-based cooling assembly may be installed in line with, at the end of, or as a substitute for, any ventilation conduits or tubes in the arc management device, or in the backplane of the arc management device, or the like, to absorb energy from the arc byproducts, cool them to a safe temperature, and vent them inside the equipment cabinet.

主权项

1. Arc resistant electrical distribution equipment, comprising:
a passive arc management device installed on the electrical distribution equipment; a ventilation port formed in the arc management device and having a size and shape to expel arc byproducts resulting from arcs that occur in the electrical distribution equipment; and a filter housing located on the arc management device, the filter housing having a cooling filter housed therein, the cooling filter positioned to receive the arc byproducts expelled from the ventilation port; wherein the cooling filter has a sufficiently high heat absorption capacity to cool the arc byproducts to a temperature where the arc byproducts can no longer reignite.
