During normal opening or short-circuit interruption, the moving , causing it to separate from the fixed . Due to the special design of the moving and fixed , an axial magnetic field is generated between them. This field controls the arc, causing it to burn uniformly and move across the .
When the arc current naturally passes through zero, the remaining ions, electrons, and metal vapor, under the influence of the electromagnetic field, quickly recombine or condense on the .
The dielectric strength across the interrupter gap is rapidly restored, thereby extinguishing the arc and achieving the purpose of interruption.
