FIELD: electrical engineering.
SUBSTANCE: invention relates to arc-quenching chamber for electric arc quenching in an contactor. Chamber comprises arc-quenching device, air blowing device, which blows electric arc in arc-quenching device, and multiple lamella electric arc quenching elements between which flow channels are formed. Flow channels have a dispersion section, sections of adjacent scattering of fluid channels are made with different slopes, so that blown air is deflected by flow channels in different directions. Invention also relates to contactor with such arc-extinguishing chamber.
EFFECT: technical result is prevention of accumulation of electroconductive plasma in arc quenching device, which increases reliability and service life of switching contactor.
