Abstract:

In this paper,the ideal mathematical calculation model of the impact bouncing time is established,based on the dynamic analysis of the impact bouncing process of the moving contact of the closing vacuum contactor.According to the design and test data,the maximum impact bouncing time is calculated and compared,which verifies the validity and accuracy of the theoretical model.The influence of the change of relevant independent variables to the impact bouncing time is analysed quantitatively.

Key words: vacuum contactor, dynamic analysis, impact bounce time, moving contact
