| Abstract: | In paper basic processes and mechanism of arc restrike is illustrated, and the great influence of electric-field distribution is explained to solve the problem of arc restrike. An electrostatic field calculation method is proposed, which can be used to analyze and predict arc restrike phenomenon and its position. With the help of this method, arc restrike can be controlled to improve DC-CB’s capability and reliability. |
