Dianci bileiqi, 2011 复合绝缘子的结构特点以及安装环境导致其电位分布不均匀,两端金具附近具有强电场区。随着电压等级和复合绝缘子结构高度的增大,这种现象愈加严重。强电场将导致外绝缘介质和金具表面发生电晕放电,降低绝缘子的运行寿命,对电力安全运行造成严重威胁。笔者通过对110 kV、220 kV的普通伞型与特殊伞型4种复合绝缘子的电场对比计算表明,绝缘子伞裙结构对其表面电场分布影响较小。

A novel numerical comparator based on single electron devices(一种新型的单电子数值比较器)
Zhejiang Daxue xuebao. Lixue ban, 2010 基于单电子晶体管的I-V特性,在构建反相器的基础上,推出了或非门及与或非逻辑门,并最终实现了一种新型的2位单电子数值比较器,利用SPICE模拟器验证了电路设计的正确性.该比较器结合了单电子晶体管与MOS管的优点.分析结果表明：与仅由单电子晶体管实现的比较器相比,电路的驱动能力提高的同时减少至少12个晶体管；与具有相同逻辑结构的CMOS实现的电路相比,该新型比较器使用了简单的单电子器件,使得电路的结构尺寸得到了极大的缩小,电路的功耗仅在10-10 W数量级上,为将来超大规模集成电路进一步微型化奠定了基础.

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Titanium (Ti)–steel composite joints are prone to the formation of compounds such as TiC, TiFe, and TiFe2 during solid‐phase bonding. This phenomenon leads to premature failure and significantly reduces the bonding quality of the joints. However, the fracture behavior of the joint influenced by these compounds, particularly on the initiation ...

Gaoya dianqi, 2023 GIS局部放电是造成绝缘材料劣化、电气设备故障的主要原因，检测GIS腔体内部的局部放电情况，有助于保证电力系统的安全可靠运行。然而在实际工程中，GIS内部结构较为复杂，不同弯角和绝缘子结构必然会对电磁波和光信号的传播特性产生一定的影响。文中根据252 kV GIS的结构尺寸，建立仿真模型，研究不同距离、不同弯角结构、不同绝缘子下电磁波和光信号传播特性的差异，得到电磁波和光信号在设备腔体内部的变化规律。仿真结果表明，随着与放电源距离的增大，电磁波信号在400 mm以外电场强度幅值近似呈线性衰减趋势 ...
