FIELD: turbines or turbomachines.
SUBSTANCE: group of inventions relates to protection systems for air intakes of gas turbines and to gas turbine plants. Protection system for air intake of gas turbine comprises screen unit (100). Screen unit (100) comprises frame (110, 120, 160) and one or more screen components (130, 140). Carcass (110, 120, 160) has connection part (150) intended for provision of carcass attachment with possibility of disconnection. Screen components (130, 140) are detachably attached to frame (110, 120, 160). Frame contains first frame (110) and second frame (120). First frame (110) is directly attached to connection part (150), and second frame (120) is attached to connection part (150) by means of a set of connection beams (160) thereby providing indirect connection of first and second frames (110, 120) to each other. Screen unit (100) comprises first screen components (130), which are located next to each other and each of which is detachably attached from first frame (110) independently of other components, and second screen components (140), which are located next to each other and each of which is detachably attached to second frame (120) independently of other components. Second screen components (140) are shifted relative to said first screen components (130) both in the transverse direction and in the longitudinal direction. Disclosed is gas-turbine plant.
EFFECT: technical result consists in improvement of maintenance quality of protection system for air intake of gas turbine.
