Abstract >Nowadays, ester‐based transformer oil has been an interest in high voltage transformers as an insulating and cooling medium. In‐service transformer oil is subjected to electrical and thermal stresses, leading to degradation process of the oil. In this work, a tapered single mode‐multimode‐single mode (SMS) optical fiber structure was used to detect transformer oil aging based on the change in oil refractive index (RI). An optical sensor was fabricated by splicing technique and chemical etching. For comparison, five samples of transformer ester oils were examined. The results show that high‐level‐aging transformer oil possesses a greater RI than fresh transformer oil. A correlation analysis was conducted among sensor output signal, oil absorption spectrum test, and breakdown voltage test. The performance of the sensor demonstrated good sensitivity and linearity of 20.41?nm/RIU and 95.95%, respectively. The single mode‐multimode‐single mode sensor was easily fabricated, low cost and could be used for real‐time high voltage transformer monitoring. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><abstract type =“main”xml：lang =“en”> <标题类型=“main”>抽象</ title> <P>现在，基于酯类的变压器油是对高压变压器的兴趣作为绝缘和冷却介质。在役变压器油经受电气和热应力，导致油的降解过程。在这项工作中，锥形单模 - 多模 - 单模模式（SMS）光纤结构用于检测基于油折射率（RI）的变化的变压器油老化。通过拼接技术和化学蚀刻制造光学传感器。为了比较，检查了五种变压器酯油样品。结果表明，高级老化变压器油具有比新鲜变压器油更大的RI。传感器输出信号，吸油谱测试和击穿电压测试中进行了相关性分析。传感器的性能分别显示出良好的敏感性和线性，分别为20.41Ω/ rIU和95.95％。单模 - 多模单模传感器易于制造，低成本，可用于实时高压变压器监控。</ p> </摘要> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-24977/'>《Microwave and optical technology letters》</a> <b style="margin: 0 2px;">|</b><span>2020年第2期</span><b style="margin: 0 2px;">|</b><span>共6页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> </p> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zkzz" style="display: none;">展开▼</span> </div> </li> <li> <div style="display: flex;"> <span class="lefttit">作者单位</span> <div style="position: relative;margin-left: 3px;max-width: 639px;"> <div class="threelineshidden zhankaihshouqi" id="fOrgthree"> </div> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zhdw" style="display: none;">展开▼</span> </div> </div> </li> <li > <span class="lefttit">收录信息</span> <span style="width: 86%;vertical-align: text-top;display: inline-block;"></span> </li> <li> <span class="lefttit">原文格式</span> <span>PDF</span> </li> <li> <span class="lefttit">正文语种</span> <span>eng</span> </li> <li> <span class="lefttit">中图分类</span> <span><a href="https://www.zhangqiaokeyan.com/clc/1165.html" title="光学">光学;</a></span> </li> <li class="antistop"> <span class="lefttit">关键词</span> <p style="width: 86%;vertical-align: text-top;"> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=aging measurement&option=203" rel="nofollow">aging measurement;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=chemical etching&option=203" rel="nofollow">chemical etching;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=optical fiber&option=203" rel="nofollow">optical fiber;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=SMS structure&option=203" rel="nofollow">SMS structure;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=transformer oil&option=203" rel="nofollow">transformer oil;</a> </p> <div class="translation"> 机译：老化测量;化学蚀刻;光纤;SMS结构;变压器油;
