摘要

本文的目的是分析用电负荷对用电设备热应力红外热像的影响方式。为了获得可靠的红外调查结果,必须满足几个条件,如确定好校正参数和选择最佳的环境条件进行调查。本文介绍了在采集热图像后对集热器母线系统的电负荷进行校正以确定其热应力的方法。在实验装置上,进行了几次尝试,以确定HV(高压)集电极母线系统的一部分的热应力,该系统具有具有相同电负载的两个分支。

Considerations regarding infrared thermal stresses monitoring of electrical equipment
The paper aim is to analyze the way in which the electrical load influences the infrared thermal images of the thermal stresses of electrical equipment determined by using infrared thermography devices. In order to obtain a reliable result of the infrared investigations several conditions must be accomplished, such as good definition of the correction parameters and choosing the optimal environmental conditions to perform the investigation. The paper presents the way in which it is corrected the electrical load of the collector busbar system after the thermal image was captured in order to determine its thermal stresses. On an experimental setup there were performed several attempts to determine the thermal stress of a portion from a HV (high voltage) collector busbar system which has two ramifications with the same electrical loads.
