PANELBOARD POWER BUS WITH ARC TRANSFER FOR PASSIVE ARC CONTROL

摘要

Methods and systems for limiting damage caused by arcs in bus stacks provide an arc transfer feature on each side of the bus stack. The arc transfer feature captures any arcs forming near busbar connection points and transfers the arc away from the busbar connection points to the interior of the bus stack. Phase barriers along the length of the interior of the bus stack then direct the arcs toward the end of the bus stack. At the end of the bus stack, a bus end interrupter receives and extinguishes the arcs.
