0 引言 红外技术是研究红外辐射的产生、传递、转换、探测并实现在实际工作中应用的一门科学技术。红外技术的原理是基于自然界一切温度高于绝对零度的物体都在不断地、自发地辐射出红外线,也就是说,自然界中的一切物体都存在着一种与人眼能辨别的反射图形十分相似的热辐射图形。因此,可以通过红外技术把这种物体上存在的热辐射图形转变为人眼可见的热图像。近几十年来,红外技术在许多领域得到了越来越广泛的应用。在电力系统,主要通过红外测温仪测量电力设备
0 Introduction Infrared technology is to study the production of infrared radiation, transmission, conversion, detection and implementation of a practical application of science and technology. Infrared technology is based on the principle that all objects in the world whose temperature is higher than absolute zero are continuously and spontaneously radiate infrared rays. That is to say, all objects in nature have a reflection pattern that is similar to the human eye Thermal radiation pattern. Therefore, the thermal radiation patterns present on such objects can be transformed into the thermal images visible to the human eye by infrared technology. In recent decades, infrared technology has been more and more widely used in many fields. In power systems, power equipment is measured primarily by infrared thermometers
