A system for an electric machine (10, 12) may include a fixture (162) including a fixture base (168) defining a first fixture tooth (172, 172a). A fastening void (178, 178a) is defined by the first fixture tooth. The fastening void may extend into the fixture base. A stator winding (22) defines an opening (206) therethrough. A coil carrier (164) defines a carrier body (190) and is configured to operably couple the stator winding to the fixture base.

The disclosure provides a system and method for separation and use of nitrogen from inlet air or flue gas, e.g., in a gas turbine (GT) engine (100). A system according to the disclosure includes a nitrogen separator (170) coupled to an ambient environment and configured to separate the ambient air into a nitrogen rich stream and a nitrogen reduced stream. A first conduit (124) is coupled to the nitrogen separator and configured to transmit the nitrogen reduced stream to an inlet of a GT engine. The nitrogen separator alternately can remove nitrogen from a flue gas.

Devices, systems, and methods for energy storage control cabinets supplying power to electrical devices may include an energy storage control cabinet with an uninterruptible power supply (UPS) including a battery backup and that receives a power supplied to the energy storage control cabinet; and one or more electrical control components powered by current from the UPS, each using two or fewer power conversions in the energy storage control cabinet of the power supplied to the energy storage control cabinet.

A system (10) includes an inlet portion (42) of a gas turbine system (18). The inlet portion (42) includes an inlet casing (110). The inlet casing (110) includes an inlet casing portion (118) and an additional inlet casing portion (116) removably coupled to the inlet casing portion (118). The inlet portion (42) also includes a bearing housing (112) having a bearing housing portion (152) disposed between the inlet casing portion (118) and the additional inlet casing portion (116). The bearing housing portion (152) is removably coupled to the inlet casing portion (118), and the bearing housing (112) is configured to house a bearing (158, 160) configured to at least partially support a rotor (60). The inlet portion (42) also includes a reinforcement assembly (114) extending axially between a surface (348) of the bearing housing portion (152) and a surface (172) of the additional inlet casing portion (116). The reinforcement assembly (114) is configured to transfer a rotor axial load from the bearing housing portion (152) to the additional inlet casing portion (116).

A battery energy storage system (BESS) control cabinet includes one or more electrical components powered by a power supply to the BESS control cabinet; and a universal power input front end separating the power supply from the one or more electrical components and able to convert, using a transformer, a power transformer, or an isolation transformer, the power supply from any voltage outside of an operating voltage of the one or more electrical components to the operating voltage of the one or more electrical components.

Described herein are compositions, and more particularly to alloy compositions and articles formed with the alloy compositions. The alloy compositions are broadly applicable in applications requiring alloys with at least one of improved hardness stability, improved Charpy performance, and improved creep strength at higher operating temperatures.

The present invention relates to a medium- or high-voltage circuit breaker (10) comprising a first electric arcing contact (11) and a second electric arcing contact (12) that are axially movable relative to each other between an open position, where the arcing contacts are separated, and a closed position, where the arcing contacts (11, 12) are in contact. The circuit breaker (10) includes an auxiliary nozzle (22) made of a fluorocarbon polymer or of polyethylene, polyamide, polyimide, polyketone, polyacetal, polysulfone, polysulfur, which is connected to a support member (20) via a threaded connection (24). To prevent loosening caused by operational vibrations or shockwaves during arcing events, the threaded connection is equipped with an anti-loosening mechanism. Various embodiments of the anti-loosening means (25) are disclosed, including a compressible annular member (27) that increases friction between threads, spring-loaded pins (32) interacting with contour pockets (36), elastic ratchets (39) engaging with recesses (41), and an annular brim (47) cooperating with an annular protrusion (45). These mechanisms ensure that the auxiliary nozzle (22) remains securely attached to the support member (20) in a screw-in position, while allowing for easy assembly. The invention provides a robust, reliable connection between the auxiliary nozzle (22) and the support member (20), enhancing the performance and durability of the circuit breaker (10) under high mechanical and thermal stress conditions.
