1000 MW汽轮发电机矩形不锈钢空心绞线的涡流检测技术

Eddy Current Testing Technology of the Stainless Steel Hollow Conductor in the 1000 MW Turbine-Generator

介绍了1 000 M W汽轮发电机组矩形不锈钢空心绞线的涡流检测,在分析了不同缺陷大小、形状、检测频率和检测速度下的涡流缺陷信号后,发现了规律,有助于对实际产品的检测。

The eddy current test on the rectangular stainless steel hollow conductor in the 1 000 MW tur-bine-generator was introduced. After the defect signals cor-responding to the different experiment parameters （size ＆shape speed of the defect under different testing speed and frequency） were analyzed, the behavior rule was founded, capable to provide the reference for the actual product test-ing.
