Tóm tắt:

he vacuum contact pair located in interruption chamber (The vacuum contact pair) is the corecomponent ofswitchgearsused in mining power systems. The design and evaluation process of thevacuum contact pair are often influenced by empirical parameters. With the advancement of moderntechnology, the application of numerical simulation tools in vacuum contact pair designhas significantlyimproved reliability and shortened the design time. This paper presents the analysis and design of avacuum contact pair using the finite element method (FEM) implemented in ANSYS software.Experimental validation was conducted on a physical prototype to verify the theoretical results. Thefindings of this study provide a solid scientific basis for domestic manufacturers to develop and producevacuumswitchgears, contributing to the replacement of imported equipment for mining power systems.
