, 2007 采用固相合成法制备了SnO2掺杂的TiO2基压敏电阻系列样品，并通过XRD和SEM分析，以及I-V曲线测量对材料的结构和电学性能进行了研究。结果表明：SnO2的掺杂抑制了晶粒的生长，晶界相含量增加。电性能测试结果显示，SnO2的掺杂量在0～1.5 mo1％内，击穿场强随SnO2掺杂量的增加单调递增；非线性系数先增加后又减小，掺杂量为0．8 mo1％ 的样品具有最大的非线性系数(α=8.3 ...

Gaoya dianqi为保证特高压直流输电系统安全稳定运行，工程中常在高压直流线路上安装带串联间隙线路避雷器（externally gapped line arrester，EGLA），当线路遭受较强雷击时EGLA的串联间隙被击穿，雷电流通过本体SVU泄放，雷电流过后EGLA需及时、可靠切断续流，恢复高阻状态。因此对EGLA续流特性和动作负荷特性的研究关系到EGLA参数设计和选型配置，具有重要工程意义。但目前鉴于缺乏超、特高压大容量续流实验平台，因此相关研究较少，导致SVU参数确定缺乏依据。文中基于山西晋北—江苏南京±800
