摘　　要：笔者针对复合绝缘子的运行现状,提出了基于多光谱法的联合检测技术,将可见光检测、红外检测、紫外检测技术有效结合。文中对于可见光检测、红外检测和紫外检测的原理分别进行了论述,对三者的优缺点进行了比较,从应用环境要求、检测仪器要求、重点检测部位、检测评估方法和缺陷处理方法等5个方面对多光谱法的应用进行了研究。多光谱法在500 kV交流输电线路和±660 kV直流输电线路的成功应用表明,多光谱法易对绝缘子进行带电检测,能够及时发现复合绝缘子缺陷,便于开展大面积的巡检。In this paper,considering the operating status of composite insulators,multi-spectral detection technology is proposed,which combined visible light detection,infrared detection and UV detection technology effectively. Principles of the three are discussed separately,when advantages and disadvantages are compared. Application environmental demands,instrument performance,focused detection part,assessment method and defect treatment method are also studied. Furthermore,applications in 500 kV AC transmission line and ±660 kV DC transmission line are studied in this paper,which indicate that multi-spectral detection is a effective way to detect defects in line composite insulators,so as to avoid malfunction occurrence.
