ARC CONTROL CHAMBER Russian patent published in 2009 - IPC H01H9/34 H01H33/08 

FIELD: electrical engineering.

SUBSTANCE: chamber comprises two isolated LH and RH sets of metal plates separated by air gap. It comprises also first group of RH and LH sets of insulating plates separated by air gap. Note here that metal plates seat in symmetry with the axis passing between LH and RH sets of aforesaid plates, the upper LH and RH plates being interconnected by current conducting bus. In compliance with this invention, second group of LH and RH sets of plates are additionally introduced. Note here that LH and RH sets of insulating plates of first and second group are jointed to LH and RH sets of metal plates to make air gaps aligned and allowing formation of two-way through cooling channels perpendicular to electric arc.

EFFECT: intensive arc cooling, higher efficiency of suppressing induction currents.
