description: This work is devoted to the methods of switching AC and DC circuits by switching devices based on power semiconductor technology, including the hybrid principle â a combination of contactless and contact devices. The tasks that were solved in the course of the study: 1. Review and analysis of existing solutions in the field of switching AC and DC nonâcontact and combined (hybrid) circuit breakers. 2. Calculation of shortâcircuit currents in the network before and after modernization 3. Derivation of the dependence of the shortâcircuit current on the resistance TOU 4. Selection of the main elements of TOU 5. Evaluation of the economic efficiency of TOU As a result of the work, it was shown that it is possible to increase the switching capacity of standard medium voltage switches by forcibly extinguishing the arc when part of the current is diverted to a shunt circuit formed by a thyristor bipolar switch.
