摘要:EAST(Experimental Advanced Super-conducting Tokamak)低温系统是 EAST 托卡马克的重要
子系统之一,氦透平膨胀机又是氦低温系统的核心部件,其性能的好坏直接影响其所在低温系统的性能,
所以在没有实际应用低温系统之前,有必要对其性能进行实际工况的测试,这就需要一个可以满足测试的
测试平台。本文主要论述了,氦透平膨胀机测试平台的设计过程,搭建过程及在此测试平台上氦透平膨胀
机实际工况测试过程。测试结果表明该试验平台可以满足对多种结构型的氦透平膨胀机进行测试且运行效
果良好。

Abstracts: The cryogenic system is one of the most important subsystems of EAST(Experimental
Advanced Super-conducting Tokamak) helium turbine is the core part of helium cryogenic
system,the character of the helium turbine is influence the cryogenic system’character. Before
the the helium is used,a testing is needed. The designing and the building process of the helium
turbine testing platform are given, The testing process and the operational experience are also
present in this testing platform can meet the testing need and the testing results
are good.
Key words:helium turbines;EAST cryogenic system;testing plant;design and testing.
