Abstract
Official abstract text for this publication.
The invention relates to a single-pole switching unit having a housing comprising a moving contact bridge and a pair of fixed contacts cooperating with said moving contact bridge and respectively connected to a current intake conductor, two electric arc cutoff chambers respectively opening onto an open volume of the moving contact bridge, each cutoff chamber being connected to at least one exhaust channel ( 42 ). The exhaust channel ( 42 ) comprises a rotating gate ( 48 ) designed to be rotated around an axis substantially perpendicular to the exhaust channel ( 42 ) by the passage of switching gases. The rotating gate ( 48 ) comprises an edge ( 54 ) positioned across from an inner wall ( 56 ) of the exhaust channel, in the first obstruction position. The arrangement of the rotating gate ( 48 ) and the inner wall ( 56 ) is such that the distance between said edge ( 54 ) and said inner wall ( 56 ) remains constant and equal to said first distance up to a first threshold value of the angle of rotation of the rotating gate ( 48 ), then increases linearly up to a second rotation angle threshold value corresponding to complete opening of the discharge channel. The invention also relates to a switching unit comprising at least one single-pole switching unit.
First claim
Opening claim text (preview).
