Passive arc management system with a flue chamber
ActiveUS20130279083A1Total current dropReduce heatNon-enclosed substationsSwitchgear arrangementsElectricityElectrical connection
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.
