description: This work is devoted to the modernization of an gas-insulated circuit breaker, for the successful switching of shunt reactors and improving the breaking capacity of the circuit breaker. The tasks that were solved during the research: 1. Investigation of the causes of accidents when shunt reactors are switched into the line. 2. The effect of a pre-commutated resistor on the aperiodic component of the current occurring when shunt reactors are switched into the line. 3. Calculation of a pre-commutated resistor, for use in tripping the breaker. 4. Modernization of arc-quenching device. 5. Calculation of the contact system. 6. Calculation of the drive system. In the course of the work it was found that the main cause of accidents in substations is the occurrence of aperiodic component of current, when the shunt reactor in the line, without the possibility of tripping for a long time, which leads to the destruction of gas-insulated circuit breaker. The rating of the pre-switching resistor was calculated, it was also decided to use a pre-switching resistor when the circuit breaker is tripped. Analysis and numerical simulation of the modernized arc-quenching device was carried out, which allowed to increase the speed of the contact system of the circuit breaker, to increase the critical value of pressure when switching off short-circuit currents.
