摘要

热成像检查是一种非侵入性、非破坏性的过程，用于电力系统设施。大多数不在可见光范围内的温度特征可以用热成像仪测量，从而可以搜索瓷绝缘体的热行为。过热可以帮助发现问题，涉及绝缘体的正确操作。红外热像仪测温的精度受热像仪上设置的发射率参数的影响。实验研究了相机与绝缘体之间的距离和角度对相机发射率参数选择的影响。

Porcelain Insulator Inspection Using Infrared Thermography

Inspection with thermography is a non-invasive, non-destructive process used in Power Systems facilities. Most temperature signatures that are not in the visible light range can be measured using thermal cameras, thus enabling the search of thermal behavior of porcelain insulators. Overheating can help to detect problems, concerning the proper operation of insulators. The precision of temperature measurement using an infrared camera is influenced by the value of emissivity parameter that is set on camera. In the present study the influence of distance and angle between the camera and the insulator on emissivity parameter value selection in camera is examined experimentally.
