Abstract
The present invention provides an enclosure for housing a circuit breaker therein which utilizes a flange system to prevent enclosure components from separating from each other when an electrical fault occurs therein. The flange system includes flanges, on enclosure walls and doors, which slide into corresponding channels and interlock therein to prevent the components from separating and hot gases from escaping the enclosure when an electrical fault occurs.
Claims14
An enclosure for enclosing a circuit breaker therein, said enclosure comprising:
- a plurality of walls enclosing the circuit breaker therein;
- a flange system disposed on said plurality of walls for interlocking said walls together thereby preventing said walls from separating from each other during an electrical fault within said enclosure, said flange system having flanges that interlock with corresponding channels.
An enclosure for enclosing a circuit breaker therein, said enclosure comprising:
- a plurality of walls;
- a floor panel coupled to said plurality of walls;
- a roof panel coupled to said plurality of walls;
- a venting system having a vent cover capable of opening outwardly to permit escape of built up gasses but remaining closed otherwise in order to prevent ingress of external elements;
- and
- a flange system disposed on said plurality of walls for interlocking said walls together thereby proventing said walls from separating from each other during an electrical fault within said enclosure, said flange system having flanges that interlock with corresponding channels.
An enclosure for enclosing a circuit breaker therein, said enclosure comprising:
- a plurality of walls enclosing the circuit breaker therein;
- a flange system disposed on said plurality of walls for interlocking said walls together thereby preventing said walls from separating from each other during an electrical fault, said flange system further providing a seal for preventing hot arc gasses, which are generated during the electrical fault, from escaping the enclosure at undesired locations;
- and
- a weatherproof vent disposed on at least one of said walls for expelling the hot arc gasses and pressure generated during the electrical fault from said enclosure, said vent prohibits environmental conditions, such as rain and snow, from entering said enclosure.
An enclosure for enclosing a circuit breaker therein, said enclosure comprising:
- a plurality of walls enclosing the circuit breaker therein;
- and
- a flange system disposed on said plurality of walls for interlocking said walls together thereby preventing said walls from separating from each other during an electrical fault within said enclosure;
- wherein said flange system providing a seal thereby preventing arc gasses, which are generated during the electrical fault, substantially escaping said enclosure.
An enclosure for enclosing a circuit breaker therein, said enclosure comprising:
- a plurality of walls;
- a floor panel coupled to said plurality of walls;
- a roof panel coupled to said plurality of walls;
- and
- a venting system having a vent cover capable of opening outwardly to permit escape of built up gasses but remaining closed otherwise in order to prevent an ingress of external elements;
- and
- a flange system disposed on said plurality of walls for interlocking said walls together thereby preventing said walls from separating from each other during an electrical fault within said enclosure, said flange system comprising:
- an L-shaped flange portion disposed on each edge of each of said walls;
- and
- a U-shaped channel defined by said L-shaped flange for accepting a corresponding one of said L-shaped flange portions of a corresponding one of said walls;
- whereby said U-shaped channel of one of said walls accommodates said L-shaped flange of another of said walls.
