Abstract

EXTRACTION DEVICE (30) DESIGNED TO EXTRACT A SHORT-CIRCUITING WEDGE (20) INSERTED BETWEEN TWO CONDUCTORS (24 AND 25) TO TAKE AN ELECTROLYSIS CELL (2) OFF LINE. THE EXTRACTION DEVICE (30) INCLUDES A MEANS OF GRIPPING (31) SAID WEDGE AND AT LEAST ONE JACK (32) DIRECTED VERTICALLY AND INCLUDING A BODY (320) AND A PISTON STEM (321). A) SAID BODY (OR STEM) BEING INTERDEPENDENT WITH AT LEAST ONE HORIZONTAL SUPPORT FACE (335) DIRECTED DOWNWARDS AND LAID OUT SO THAT, WHEN SAID EXTRACTION DEVICE IS PLACED ABOVE SAID WEDGE TO EXTRACT IT, THE UPPER HORIZONTAL FACE (240, 250) OF EACH CONDUCTOR (24, 25) IS IN LINE WITH ONE HORIZONTAL SUPPORT FACE (335), B) SAID STEM (OR SAID BODY) BEING CONNECTED TO SAID MEANS OF GRIPPING (31) SAID WEDGE, SO THAT, WHEN SAID JACK (32) IS ACTUATED TO EXTRACT THE WEDGE, SAID JACK EXERTS OPPOSING FORCES ON SAID CONDUCTORS AND SAID WEDGE, TENDING TO SEPARATE THEM.
