【摘要】：在陽江核電1號機1000MW級半速核電機組上,國內(nèi)首次采用了一種汽輪發(fā)電機組基礎和凝汽器雙彈簧支撐系統(tǒng)。闡述了其汽輪發(fā)電機組基礎和凝汽器支撐設計方案及負荷分配,介紹了基礎彈簧和凝汽器彈簧的布置、結(jié)構(gòu)和釋放方法。凝汽器彈簧釋放和基礎彈簧釋放貫穿汽輪發(fā)電機組的安裝主線,為了保證凝汽器彈簧和基礎彈簧之間準確的負荷分配,協(xié)調(diào)釋放兩個支撐系統(tǒng)非常關(guān)鍵。首次系統(tǒng)性、完整地歸納總結(jié)并提出了凝汽器彈簧和基礎彈簧協(xié)調(diào)釋放邏輯,明確了彈簧首次釋放的先決條件以及安裝調(diào)試階段與啟停機過程中重新鎖固和再釋放的時機,并指出了相關(guān)工藝過程的注意事項,為CPR1000、華龍一號、AP1000等同類型機組安裝提供借鑒和指導,是對這種核電汽輪發(fā)電機組雙彈簧支撐技術(shù)推廣應用的重要技術(shù)補充。
[Abstract]:On the 1000MW half speed nuclear power unit of No. 1 nuclear power unit of Yangjiang Nuclear Power Plant, a kind of turbogenerator unit foundation and double spring support system of condenser are adopted for the first time in China. The design scheme and load distribution of the foundation and condenser support of the turbine generator set are described. The arrangement, structure and release method of the base spring and condenser spring are introduced. Condenser spring release and base spring release run through the main installation line of turbine generator set. In order to ensure accurate load distribution between condenser spring and base spring, the coordinated release of two supporting systems is very important. The coordinated release logic between condenser spring and base spring is summarized and put forward systematically for the first time, and the precondition of the first release of spring and the opportunity of re-locking and rereleasing during installation and commissioning are defined. The paper also points out the matters needing attention in the relevant technological process, which provides reference and guidance for the installation of the same type units such as CPR1000 and Hualong No. 1 AP1000, and is an important technical supplement for the popularization and application of the dual-spring support technology for this type of nuclear power turbine-generator set.
