INSULATION ARRESTER Russian patent published in 2015 - IPC H01B17/00 

FIELD: electricity.

SUBSTANCE: at the impact of atmospheric overvoltage on an insulation arrester at first the air spark gap is broken between the lower feed electrode (13) and the lower vertical tap (8) of the lower fin (15), and then spark gaps are broken between intermediate electrodes of single tubular chambers (5). Then the air spark gap is broken between the upper feed electrode (12) and the upper vertical tap (7) of the upper fin (14) and spark gaps of the single tubular chambers (5), in the latter electric spark channels occur between the intermediate electrodes. When an electric spark channel is expanded high pressure is generated, and under the impact of this pressure they are blown through nozzles (6) outside to the air surrounding the fin (4). In water trapped by a circular groove and through radial channels and supplied to inner cavities of the single chambers (5) electric sparks generate the occurrence of burst waves and hydrodynamic flows, which impact on the electric spark channels between the intermediate electrodes.

EFFECT: increasing the efficiency of the insulation arrester.
