| Abstract: | In this paper a new style bipolar axial magnetic field electrode structure used in vacuum interrupter is presented, which results symmetric alternating axial magnetic field distributing intensively and evenly between the electrodes. Thus, no slots on the electrode are needed, and the structure strength of the whole electrode are increased. Replacement of solid block iron core by stromatolithic iron core reduces the eddy current and the lag time of the axial magnetic field behind the arc current. The result of test shows that this electrode structure can reduce the arc voltage and increase interrupting current capacity of vacuum interrupter. |
