description: Theme of final qualification work: "Development of a methodology for calculating the contact system of a vacuum circuit breaker 10kV, 1600A." In this work, we analyzed the design of a vacuum circuit breaker with a voltage of 10 kV and a current of 1600 A; The disadvantages of this switching device are shown; transition resistance is considered. The results of numerical simulation of the transition resistance are presented. The work was carried out using the COMSOL MULTIPHYSICS software package and the Autocad design system, where the model and its elements were developed, as well as the processes of the contact system of a vacuum circuit breaker with a voltage of 10 kV and a current of 1600 A. As a result, a calculation method was developed that allows one to determine the value of the transition resistance at the ends of the contacts of a given switching apparatus, limiting its switching resource and service life. The dependences of the transition resistance on such parameters as: contact pressing, the average height of the micro points at the ends of the contacts and their average slope are shown. Interfaces for the distribution of electrical potential and conductivity at the switch contacts are given.
