Abstract (en)
A direct-current load-break switch (1) particularly for traction lines, suitable for installations in a metallic cell, with two interruption segments in series, comprising: two fixed contacts (5); a double moving contact (8), which is adapted to engage and disengage with respect to the fixed contacts (5); means for actuating the moving contact (8) which are adapted to move the moving contact (8) so that it engages and disengages the fixed contacts (5); each fixed contact (5) and the corresponding moving contact (8) are provided with an arc quenching horn (6, 10), and a coil provided with a magnetic core (12, 13) is connected electrically between the arc quenching horn (6, 10) (which is insulated) and the fixed contact; one or more arc quenching chambers are further arranged above the interruption segment formed by the arc quenching horns (6, 10).
