FIELD: electrical engineering.
SUBSTANCE: gas-filled switchgear apparatus contains a grounded gas-filled body, a stationary contact, a movable contact and a receptacle; connected to the cavity formed by the stationary contact inner surface and the movable contact are additional means for delivery of an insulation gas into such cavity; one ensures that the pressure inside the gas-filled body cavity p1 exceeds that in the stationary contact cavity p2 provided the movable is plugged in.
EFFECT: reduction of the apparatus cost and overall dimensions and possibility of per phase control due to manufacture ease improvement.
