热核聚变实验堆中超导母线绝缘层的红外热波检测
Infrared thermal wave imaging for inspecting the insulation layer of superconducting busbar in thermonuclear experimental reactor
摘要
Abstract
This work aims at developing a thermal wave imaging method for testing the insulation layer of superconducting busbar in thermonuclear experimental reactor. In the paper, a film bag filled with hot water is used to heat the sample surface. The approxi- mate theoretical model of transient heat conduction under an instantaneous cylindrical surface source in cylindrical structure is given. Through simulation and analysis of the theoretical model, it is found that differential processing of the thermal cooling signals can improve the signal contrast between defects and non-defects areas. Compared with the flash pulse excitation method, the contact excitation method can detect deep defects.关键词
