界面电荷注入与积聚行为对直流GIS/GIL绝缘子沿面电场的影响分析
Gaoya dianqi, 2021 气体绝缘组合电器(gas insulated switchgear,GIS)和气体绝缘金属封闭输电线路(gas insulated metalenclosed transmission line,GIL)运行电流大,设备内部存在明显的温度梯度分布,造成高压电极附近电荷的注入与迁移加剧,导致绝缘子内空间及表面电荷的积聚,畸变电场,容易诱发沿面闪络故障。为此文中建立了电—热耦合应力下直流盆式绝缘子内的电荷注入与积聚模型,研究了考虑电荷注入和迁移特性的绝缘子空间电荷及表面电荷积聚情况 ...

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT NiTi shape memory alloys (SMAs) show excellent performance in vibration damping and corrosion resistance. However, due to low hardness and lack of self‐lubrication, they suffer severe friction and wear during service. Although various strategies including doping and heterostructure design have been proposed, the effects are unsatisfactory.
