POLYPHASE CIRCUIT INTERRUPTER OF THE FLUID BLAST PUFFER-TYPE

摘要

A polyphase puffer-type circuit interrupter with a plurality of pole units in which a blast of gas is generated within a puffer mechanism to extinguish the established arc. The gas under pressure flows out of a blast orifice and escapes in a downstream compartment. All downstream compartments of the different pole units communicate with each other so as to increase the flow of the blast gas.
