电力变压器绕组热点温度的在线测量对于确保其安全稳定运行具有重要的意义。本文提出一种基于光纤光栅的绕组热点测温方法,首先简要介绍了测温方法的基本原理,之后对测温系统的结构及关键技术进行了讨论,最后针对不同用户的需求,设计了不同的安装结构,进行了实际测试。实测结果表明,系统能够实时测量绕组温度变化,对变压器绝缘状况的评估将提供重要依据。

英文摘要:

The on-line measurement of hot-spot temperature in transformer winding is an effective factor to identify the insulation condition of power transformer. In this paper, a novel temperature measurement method based on fiber grating is presented. The principle is introduced at first, and then the configuration and key problems are discussed. The on-line measurement of novel method is progressed at last. The testing results show that this new method is accurate and reliable. It will provide powerful support for the insulation condition evaluation of power transformer.
