特高压GIL现场交接验收与机械缺陷检测平台的设计与实现

open access: yesGaoya dianqi
为了探索适合特高压GIL设备的现场交接验收及机械缺陷检测方法,文中对传统GIL设备交接验收时的交流耐压试验、投运前绝缘性能考核试验及局部放电试验进行了改进,采用与振动检测法相结合的方式。在此基础上研制了GIL综合试验与机械缺陷检测分析平台,并融合了出厂试验数据、历史运行数据、常规检测数据及改进后的交接试验数据进行多源多参量分析。解决了传统方法无法判别GIL设备微小机械缺陷的问题,使运维人员能够更加全面的掌握GIL设备的状态。现场应用实例表明,该平台能切实提升特高压GIL设备的现场交接验收效率及规范性 ...

220 kV共箱式GIL壳体电位升高抑制策略研究

open access: yesGaoya dianqi
壳体电位升高是气体绝缘输电线路(GIL)运行的关键问题。当混联输电线路遭受雷击或不对称短路等故障时,三相共箱GIL壳体上将产生显著的感应电势。针对三相共箱GIL壳体电位升高问题,目前缺乏相应的壳体电位升高抑制策略研究。因此文中依托实际工程,建立220 kV三相共箱GIL混联输电线路的等效电路模型,分析不同工况下GIL壳体电位升高的原理及影响因素,从而提出了壳体电位升高抑制策略,并通过电磁暂态仿真进行了验证。研究表明:发生单相接地短路故障时,壳体电位提升最大;当存在雷电侵入波 ...
