FIELD: electrical and radio engineering; one-sided switchgear and control gear with vacuum circuit breakers. SUBSTANCE: proposed installation has cabinet accommodating monoblock that integrates vacuum circuit breaker and vacuum chambers, as well as ground disconnecting switch with movable contacts. This monoblock can be removed from cabinet upon grounding cables without de- energizing collecting buses. Axes of collecting buses, those of vacuum chambers and of contacts of ground disconnecting switches are disposed not in lines but in triangle in three relatively perpendicular spatial directions. EFFECT: facilitated maintenance and repairs of switchgear and control gear. 5 cl, 11 dwg
