Abstract
An arc chute arrangement for arc quenching in electrical switching device, said arrangement comprising a plurality of deion plates, each said deion plates further comprising a pair of plates having an ablative material sandwiched therebetween; a lining means for holding said deion plates; wherein said deion plates having a chamfered profile at one corner to generate high magnetic field that drive the arc inside arc chute and said chamfered profile arranged alternatively thereby substantially lengthening the arc.
Claims7
An arc chute arrangement for arc quenching in electrical switching device, said arrangement comprising:
- a plurality of deion plates, each said deion plates further comprising at least a pair of plates joined through a resistive element and having an ablative material sandwiched therebetween;
- a lining for holding said deion plates;
- wherein said deion plates are made of same ferromagnetic material or optionally made of different magnetic materials whereby said materials are selected so as to provide substantially high arc running capacity and
- wherein said deion plates comprising chamfered profile at its one corner to generate high magnetic field that drive the arc inside arc chute and said chamfered profile of two consecutive deion plates being arranged in an alternative relationship so that the arc forms a zig zag path resulting in substantially lengthening of the arc.
