Abstract (en)
[origin: EP0678886A1] The medium or high tension circuit breaker comprises an envelope filled with dielectric gas, and a cut-off chamber (30) containing metal plates (14) for splitting up the electric arc into a number of smaller elementary arcs under the action of a magnetic field. The chamber includes a helicoidal insulating ramp (13) wound about a central generator axis (13a). This ramp is arranged around the internal edge of the chamber about a central conducting electrode (12). The metal plates are arranged along the length of the ramp, around and spaced from the central conducting electrode. <IMAGE>
