摘　　要：反常的温度分布往往能反映设备的非正常运行状态。红外图像为有效测量物体的温度及相对温度分布提供了便捷的途径。本文分别从理论和实验上分析与验证了太阳光伏阵列在正常光照、遮挡、故障以及典型负载、开路、短路等情况下的温度变化及相应的红外图像,为进一步在大面积的太阳光伏利用中实现非接触式的在线检测与故障分析提供依据。Anomalous temperature distributions are often an indication of atypical behavior in a device under investigation. Infrared cameras provide a convenient effective method for measuring both absolute and relative temperatures distributions of an object. The temperature changes and infrared images corresponding of photovoltaic array working at typical load, open-circuit and short-circuit under normal solar illumination, shadow and breakdown condition were analyzed and tested theoretically and experimentally, respectively. This work provides scientific basis for subsequent non-contact on-line detection and fault analysis in abundant application of photovoltaic array.
