摘要： The microalloyed martensitic stainless steel grade 403Cb disclosed herein specifies a composition range including a minimum level and a maximum level that improves material properties leading to increased toughness and strength. In addition, a chromium-nickel equivalent balance (CNB) is controlled within a proper level. With increased toughness and strength, the sensitivity to temper brittleness is decreased.

摘要： A nozzle segment (100) includes an inner band (104), an outer band (106), and at least one nozzle vane (102) extending between the inner and outer bands (104, 106). The outer band (106) includes a hook (126) that extends radially outwardly from an outer surface (122). The hook (126) is oriented to couple to a support (17) within different first and second turbine engines (10). The hook (126) extends circumferentially across the outer surface (122) and includes slots (130) defined therein. A first slot (130) includes a first circumferential load surface (132), and a second slot (130) includes a second circumferential load surface (132). When the nozzle segment (100) is coupled within the first turbine engine (10), the first circumferential load surface (132) engages an anti-rotation element (48) while the second circumferential load surface (132) does not engage an anti-rotation element (48). When the nozzle segment (100) is coupled within the second turbine engine (10), the second circumferential load surface (132) engages an anti-rotation element (48) while the first circumferential load surface (132) does not engage an anti-rotation element (48).

摘要： In the field of high voltage direct current (HVDC) power transmission, there is a need for an improved power dissipating converter (30).
A power dissipating converter (30) for use with a power converter (10) configured to convert between AC power and DC power, comprises first and second DC terminals (12, 14) for connection to a DC network (20). The power dissipating converter (30) also includes a converter limb (32) that extends between the first and second DC terminals (12, 14) and which includes first and second limb portions (34, 36) that are separated by a ground terminal (38) for connection to ground (40). Each limb portion (34, 36) includes a chain-link converter (44) which is connected in series with a power dissipating resistor (46). Each chain-link converter (44) includes a plurality of series-connected chain-link modules (48), and each chain-link module (48) includes a plurality of switching elements (50) that are connected in parallel with an energy storage device (52) whereby each chain-link module (48) is selectively operable to provide a voltage source and the corresponding chain-link converter (44) is selectively operable to provide a stepped variable voltage source. The power dissipating converter (30) further includes a controller (70) which is programmed to operate the power dissipating converter (30) in first and second modes, the first mode being an inactive mode in which the power dissipating converter (30) is prevented from exchanging current with a DC network (20) connected in-use to the first and second DC terminals (12, 14) and no power from the DC network (20) is dissipated by either power dissipating resistor (46), and the second mode being an active mode in which the power dissipating converter (30) exchanges a discharge current with the DC network (20) and power from the DC network (20) is dissipated by each power dissipating resistor (46). The controller (70) is further programmed to operate the power dissipating converter (30) in a third mode, the third mode being a balancing mode in which the controller (70) causes a balancing current (I) smaller than the discharge current to flow through each chain-link converter (44).
