ARC CHUTE FOR A CIRCUIT BREAKER, CIRCUIT BREAKER AND METHOD FOR ASSEMBLING AN ARC CHUTE

摘要

An arc chute for a DC circuit breaker comprising at least one stack102, 106 of a plurality of substantially parallel metal plates 104,104a,...;104n,108, 108a, 108n, the at least one stack defining a first axis A in parallel toastacking direction; an arc space 109 adapted to allow an arc to extend alongthefirst axis, wherein a second axis traversing in parallel to the metal platesthe atleast one stack and the arc space 109 substantially orthogonal to the firstaxis.Further, an arc-chute housing 111 having at least one side wall 112, said atleastone side wall being substantially parallel to the second axis, wherein thedistancebetween the at least one sidewall 112 and the metal plates is less than 5mm,inparticular less than 2mm.
