The invention discloses a low-voltage through-flow module for a 1000MW-grade nuclear power unit, relates to the low-voltage through-flow module for the nuclear power unit, and aims to solve the problems of high flow loss and low flow efficiency of an existing low-voltage through-flow module. Each stage of stationary blade group comprises multiple stationary blades with the same specification; the blade heights of the stationary blades in the eleven stages of stationary blade groups are sequentially increased; each stage of moving blade group comprises multiple moving blades with the same specification; the blade heights of the moving blades in the eleven stages of moving blade groups are sequentially increased; the stationary blades in each stage of stationary blade group are assembled on a partition plate of the low-voltage through-flow module according to the blade height increasing sequence; the moving blades in each stage of moving blade group are assembled on a rotor of the low-voltage through-flow module according to the blade height increasing sequence; the stationary blades in each stage of stationary blade group and the moving blades in each stage of moving blade group are arranged in a staggered manner; and the blade heights of the moving blades in each stage of moving blade group is higher than the blade heights of the stationary blades in the same stage of stationary blade group and lower than the blade heights of the stationary blades in the higher stage of stationary blade group.
Description
technical field [0001] The invention relates to a low-voltage flow-through module of a nuclear power unit. Background technique [0002] Compared with other energy sources, nuclear power has the unique advantage of zero carbon emissions in the production process. Therefore, vigorously developing nuclear power is one of the preferred solutions to solve my country's huge energy demand and environmental governance problems. Due to its own mechanism, the existing low-pressure flow-through modules used in nuclear power have high flow loss and low flow efficiency. Contents of the invention [0003] The purpose of the present invention is to provide a low-pressure flow module for 1000MW class nuclear power units in order to overcome the problems of high flow loss and low flow efficiency caused by the existing low-voltage flow-through module used in nuclear power due to its own mechanism . [0004] A low-pressure through-flow module for a 1000MW class nuclear power unit of the p...
