A QUENCHING CHAMBER FOR A CIRCUIT INTERRUPTER

摘要

The present invention relates to a quenching chamber (4) for a circuit interrupter (1) comprising a space (6), and at least two waiis (5) at least partially enclosing the space and positioned on opposite sides of the space. The chamber is configured to comprise, in the space, a switch having a fixed contact (2) and a movable contact (3). Each wall comprises one or more levels (a) of wall units (9), whereby the wall unit within one level extend over a width (w) along a first axis (x) and extend along a part or whole length (I) along a second axis (y) being perpendicular to the first axis, and whereby each wall unit comprises quenching material. The wall units on opposite sides of the space within the same level comprise quenching material having different quenching capabilities. The invention also relates to new combinations of quenching material and use thereof.
