description: Subject of graduate qualification work: "SF6 circuit breaker 63 kA for compensated line 750 kV". The tasks that were solved during the research: 1. Analysis of the requirements for 750 kV,63kA the gas circuit breaker. 2.Â  Arc-quenching device for an ultrahigh-voltage SF6 circuit breaker. 3. Analysis of the influence of the switched resistance on the aperiodic component of the current when the SF6 circuit breaker is opened. 4. Analysis of the contact system (systems of main and arcing contacts). 5. Analysis of the main parameters of the drive device of the SF6 circuit breaker. High voltage SF6 circuit breaker 750 kV, 63kA are analyzed. The theoretical and experimental results obtained from investigations of factors caused failures of SF6 circuit breakers occurred in switching compensated 750 kV overhead power lines are presented. Recommendations are suggested for preventing failures caused by the inability of the SF6 circuit breaker pole to interrupt current that does not cross zero for a long period of time due to the presence of large aperiodic component in it.
