FIELD: electrical engineering.
SUBSTANCE: invention relates to outdoor switchgears (OSG) of power plants and can be used on them to supply generated electric power. The outdoor switchgear of the power station, made according to the connected quadrangle diagram, contains five generator-transformer blocks, three lines, a communication autotransformer, twenty switches with a disconnector on one side, as well as normally disconnected twenty-first and twenty-second switches with disconnectors on each side.
EFFECT: reduced frequency of loss of generated and transmitted power in the outdoor switchgear when any circuit breaker fails to trip during a short circuit on any connection or when it fails in the “short circuit in both directions” mode.
