    摘要： In an embodiment, a system includes: a casing for surrounding at least a portion of a rotor, and enclosing a volume of a cooling gas thereabout, the casing including a plurality of static seals; an end housing at each end of the casing, each end housing including a seal system through which the rotor extends, wherein a portion of cooling gas escapes from the casing to at least one seal area; and a source of cooling gas fluidly coupled to the casing by a cooling gas regulator. The system may further include: a scavenging system coupled to each end housing for removing a gas mixture therefrom including a portion of escaping cooling gas; a sensor for determining a purity of the cooling gas in the casing; and a static seal leak detector that generates an alarm indicative of a leak in at least one of the plurality of static seals.
