description: This work is devoted to the development of a mathematical model of the breaking capacity of auto-generating arc extinguishing devices of a high-voltage switch. Tasks that were solved during the study: 1. Study of the interaction of 220 kV, 50 kA high-voltage switches with the network. 2. Creation of a mathematical model of an auto-generating arc extinguishing device. 3. Validation of the model. A mathematical model of an auto-generating arc extinguishing device was created to simulate the processes occurring in the shutdown arc, taking into account the deformation of the flow part of the arc extinguishing device. The empirical coefficients of the model were determined based on a comparison of calculated and experimental data. As a result of modeling, fields of parameters characterizing the process of restoring the strength of the contact gap were obtained. The evaluation of the shut-off ability of the arc extinguishing device and changes in the geometry of the flow part was carried out. In the end, assumptions were introduced about the switching resource of the switch.
