| Abstract: | Suppose that the potential on the electrodes is asymmetric and the voltage on the floating shield is unknown with the consideration of the influence of the ions on the electrode surface,the electric field distribution in the high voltage vacuum interuupter is calculated and analyzed with finite element method,thus the conclusion is drawn that the serious asymmetry of the electric field distribution in the vacuum interrupter has affected the electrical strength and the interrupting performance of the interrupter.Furthermore the proposal is advanced to make electric field distribute more uniformly or symmetricly. |
