| 摘 要： | 传统上采用Bobbin探头进行凝汽器传热管涡流检测时存在管板盲区问题。基于传热管管板区涡流检测需求，研究了CXB型阵列探头在此领域的应用。通过设计制作凝汽器模拟管板，开展了试验研究。试验发现，CXB探头能够有效解决涡流检测中Bobbin探头在传热管管板区存在的盲区问题。同时，试验解决了CXB探头对于缺陷的定量评定难题。最后给出了现场检测中的实际应用结果。

| Abstract: | Bobbin probes are used to inspect tubes of the condenser,but the inspection is subjected with the blind area problem near the tube sheet.Based on this inspection requirement,the application of CXB(Circ X+ Bobbin probe,a kind of array probe) on eddy current inspection of tube sheet area is under discussed.Experiment results by mockup show that CXB is capable of solving blind area problems encountered in tube sheet area with bobbin technique.In addition,the problem of CXB quantitative evaluation of defects is... |
