变汽温法测试过桥漏汽量的应用分析

摘要

The paper introduces the principle of steam temperature variation method for measuring labyrinth leakage. An example is giv⁃en for a 315 MW steam turbine, the impact of the various parameter measurements on the test results is calculated and analyzed. The results show that the hot reheat temperature and IP cylinder exhaust temperature have a greater impact.%介绍了变汽温法测试过桥漏汽量的原理和方法，并以某315 MW机组为例，计算分析各测量参数对试验结果的影响。结果表明，再热汽温及中排温度对试验结果影响较大。
