摘要

The material of hollow conductors in the 600M W stator bar has been studied in many years, but it is rarely to do the stainless steel conductor test and the available data is also not clear. It is significative to do the stator bars temperature measure test. The test can tell us the temperature distribution of the copper conductors on the influence of the large current when we respectively use stainless steel conductors and copper conductors. The test can help us to get the temperature change in the 600MW steam generator stator bars when the generator is running. The test can help us to know the grads and the effect on heat exchange using stainless steel conductors or copper conductors. The paper introduces the main parts of test, such as the design and manufacture of the large current generator, the design and manufacture of the cooling water system, the choice and distribution of temperature measure, the data collection system design, etc. The paper also discusses the experimental method and the difficulty with the existing test equipment under the limited condition, and shows the test methods formulation and implementation. Finally, it is obtained that the different temperature distribution gradient and temperature curve with copper hollow conductors and stainless steel hollow conductors by the test and calculation.
