| 摘 要： | 通过归纳真空开关在投切电容器组时发生重燃现象的特点，提出了发生重燃的根本原因是分闸操作中的机械振动引起灭弧室内的微粒释放所造成的，并用微粒击穿理论对真空开关在投切电容器组试验过程中发生的各种现象进行了解释，最后提出了提高真空开关投切电容器组可靠性应采取的措施。

| Abstract: | By summarizing the features of restrike during capacitor switching when using VCB and.analyzing the restrike reasons through different point of view, the real restrike reason is found to be the particulate releasing in the vacuum interrupter for the mechanical vibrate during operating. Using this theory the phenomena encountered during capacitor switching can be interpreted. Moreover, the countermeasures to improve the reliability when using VCB switching capacitor bank are point out. The paper is significant to decrease the restrike ratio of capacitor switching when using VCB. |
