description: The aim of the work is to study the thermal regime of the contact system of a vacuum circuit breaker 10 kV-20 kA/2000 A with a radial magnetic field in the nominal operating mode.In the course of the work, the designs of existing vacuum switches, the arc extinguishing chamber, the principles of its operation, the physical processes of arc extinguishing and vacuum switches were also considered. The diameter of the contact system that we will model is calculated. When considering the options of materials used for the construction of vacuum circuit breaker contact systems, a choice of materials and dimensions of the arc extinguishing chamber design was made. The types of contact systems with radial and axial magnetic fields are considered. A mathematical model has been created in the s&lt;&gt; environment. The electrothermal processes in the vacuum circuit breaker are calculated. A study of the temperature distributions of the contact system at different coefficients of thermal conductivity has been carried out. The calculation of capacities at various coefficients of thermal conductivity is made.Based on the data obtained, a radiator was designed to provide the heat sink we need and the necessary power removal from the contacts Â in environment.
