Abstract

AN ELECTRICAL CIRCUIT BREAKER (10) COMPRISES AN ENCLOSURE (12) FILLED WITH AN INSULATING FLUID. WITHIN THE ENCLOSURE (12) IS A PAIR OF OPPOSING CONTACTS (14 & 16) ONE OF WHICH IS FIXED AND THE OTHER MOVES AXIALLY RELATIVE THERETO. WHEN THE CONTACTS (14 & 16) ARE SEPARATED AN ARC IS DRAWN BETWEEN THEM. THE ARC IS ROTATED BY A MAGNETIC FIELD GENERATED BY COIL (18). A SHIELD (20) PREVENTS THE ARC SHORT CIRCUITING THE COIL (18) BUT ALSO TRAPS IONISED GAS PARTICLES AND METALLIC VAPOURS. TO PREVENT THE IONISED GAS AND VAPOURS BUILDING UP A FLOW OF PURGING GAS IS DIRECTED THROUGH CHANNELS (26 & 28) TO REGION A. THE PURGING FLOW OF GAS FLUSHES OUT THIS REGION TO PREVENT RE-ESTABLISHMENT OF THE ARC. THE MOST ILLUSTRATIVE DRAWING IS
