description: The work is devoted to the study of tripping ability of the autocompression arc chamber with SF6-insulation. The tasks accomplished in the course of the work: 1. Study of modern high-voltage gas circuit breakers with autocompression arc chamber. 2. Study of advantages and disadvantages of autocompression arc chambersÂ  and ways of their modernization. 3. Carrying out a comparative analysis of tripping capacity for different modernizations of arc chambers. The paper studies the design of autocompression arc chamber of modern gas circuit breaker and ways of its modernization in order to increase the tripping capacity. The influence of pressure and speed of current approach to zero on the tripping capacity on the basis of experimental data has been analyzed. The interaction of 330 kV, 40 kA circuit breaker with the network is investigated. Numerical experiments allowing to estimate the tripping capacity in the modernized arc-quenching device are carried out. The possibility in principle to increase the tripping capacity using the proposed modernization is shown.
