摘要

Abstract >It is crucial for cast resin transformer to detect void and delamination existing in the cast resin because these defects reduce insulation performance of cast resin equipment. Furthermore, defects are likely to be mixed in cast resin because of several surface boundaries between resin and conductor. It is considered that detecting partial discharge (PD) is effective to diagnose equipment of power equipment. However, it is reported that withstand lightning impulse voltage test may give influence on AC partial discharge test, especially partial discharge inception voltage. This paper deals with accumulated charge in a void under AC voltage to investigate the effect of the impulse voltage prestress on subsequent AC PD characteristics in cast resin transformer. AC PD characteristics were compared before and after impulse application. In addition, recovery of PD characteristics was measured to investigate charge decay. As a result, the mechanism of prestress effect is revealed and surface charge density is estimated quantitatively in cast resin transformer. </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>对于铸造树脂变压器来检测存在于铸树脂中的空隙和分层是至关重要的，因为这些缺陷降低了铸造树脂设备的绝缘性能。此外，由于树脂和导体之间的几个表面边界，可能在铸树脂中混合缺陷。考虑到检测局部放电（PD）可有效地诊断电力设备的设备。然而，据报道，耐力脉冲电压测试可能会影响交流局部放电测试，尤其是局部放电初始电压。本文涉及在交流电压下的空隙中的累计电荷，研究脉冲电压预应力对铸造树脂变压器中随后的AC PD特性的影响。在脉冲应用之前和之后比较AC PD特性。此外，测量PD特性的回收以研究电荷衰减。结果，揭示了预应力效应的机制，并在铸造树脂变压器中定量估计表面电荷密度。</ 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-22399/'>《Electrical engineering in Japan》</a> <b style="margin: 0 2px;">|</b><span>2019年第2期</span><b style="margin: 0 2px;">|</b><span>共7页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Maruyama Hirofumi&option=202" target="_blank" rel="nofollow">Maruyama Hirofumi;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Matsuo Kensuke&option=202" target="_blank" rel="nofollow">Matsuo Kensuke;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Kozako Masahiro&option=202" target="_blank" rel="nofollow">Kozako Masahiro;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Hikita Masayuki&option=202" target="_blank" rel="nofollow">Hikita Masayuki;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Iida Kazuo&option=202" target="_blank" rel="nofollow">Iida Kazuo;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Umemura Tokihiro&option=202" target="_blank" rel="nofollow">Umemura Tokihiro;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Nakamura Yusuke&option=202" target="_blank" rel="nofollow">Nakamura Yusuke;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Nakamae Tetsuo&option=202" target="_blank" rel="nofollow">Nakamae Tetsuo;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Maeda Teruhiko&option=202" target="_blank" rel="nofollow">Maeda Teruhiko;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Higashiyama Masakazu&option=202" target="_blank" rel="nofollow">Higashiyama Masakazu;</a> </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"> <p>Kyushu Institute of Technology;</p> <p>Kyushu Institute of Technology;</p> <p>Kyushu Institute of Technology;</p> <p>Kyushu Institute of Technology;</p> <p>Mie University;</p> <p>Mie University;</p> <p>Power and Industrial Systems Research and Development CenterTOSHIBA Co.
