Abstract

1281299 Arc extinguishing in switches BROWN BOVERI & CIE AG 2 July 1970 [2 July 1969] 32244/70 Heading H1N An arc chamber comprises two flat perforated inner walls 1, 2, e.g. of a ceramic filter material, inclined together along the direction of travel of the arc and having outer walls 6, 7 forming wedge-shaped clearances 4, 5 which are subdivided by vertical webs (8). An imperforated slab (17), Fig. 4 (not shown) may be inserted at the top of the chamber so as to form a truncated cone with the inclined walls. The base of the chamber may also be perforated allowing fresh air to be drawn-in from the base as well as through the perforated end-wall 13.
