Passive arc management system with a flue chamber

摘要

In an electrical distribution cabinet a mechanism providing quick, reliable, passive arc blast control has a flue chamber surrounding the likely arc site such as an electrical connection point. The flue chamber provides a flue channel which lengthens the arc and attenuates the current and temperature until the arc is extinguished. Preferably, the flue chamber and channel are formed of opposable open-faced polyhedral structures, one fitting inside the other. The mechanism is particularly suited for draw-out circuit breaker connections in a switch gear cabinet.

主权项

1. An arc management system with a passive arc attenuator, comprising:
a) electrical equipment having exposed electrical conductors; b) a cabinet separating the electrical equipment from an outside environment; c) a flue chamber within the cabinet and surrounding the electrical conductors, the flue chamber having a flue channel formed therein for the attenuation of an arc therein.
