摘要:
干式变压器内部温度的准确感知对其绝缘状态评估与运行安全至关重要。针对传统热电偶与红外测温技术存在布设困难、抗干扰能力弱，难以获取绕组内部真实温度等问题。文中设计提出了一种将光纤光栅传感器嵌入在干式变压器内部的测温方法，并开展了相关的温升测量实验，通过实时测量并采集内部多点温度数据，来实现对温度变化特性的分析。实验测试结果表明，绕组内部温升更快、降温更慢，内部与外部存在明显温差，温度演变趋势亦存在差异。与热电偶测温结果相比，光纤光栅技术具有测量精度高、响应速度快、抗电磁干扰能力强等优势，能够为干式变压器热状态评估、散热结构优化及寿命预测提供有效支撑。
Abstract:
The accurate perception of the internal temperature of dry-type transformer is very important for its insulation condition evaluation and operation safety. The traditional thermocouple and infrared temperature measurement technology has the problems of difficult layout, weak anti-interference ability, and difficult to obtain the real temperature inside the winding. In this paper, a temperature measurement method of embedding fiber Bragg grating sensor in the interior of dry-type transformer is proposed, and the related temperature rise measurement experiments are carried out. Through real-time measurement and collection of internal multi-point temperature data, the analysis of temperature change characteristics is realized. The experimental results show that the internal temperature rise of the winding is faster and the cooling is slower, there is a significant temperature difference between the internal and external, and the temperature evolution trend is also different. Compared with the thermocouple temperature measurement results, the fiber bragg grating technology has the advantages of high measurement accuracy, fast response speed and strong anti electromagnetic interference ability, which can provide effective support for the thermal state assessment, heat dissipation structure optimization and life prediction of dry-type transformer.
