110 kV三相共罐GIS避雷器相间电磁耦合对电位及电场分布的影响
Dianci bileiqi, 2022 随着110 kV三相共罐GIS避雷器的小型化，结构更加紧凑，导致三相间电磁耦合更加紧密，造成对GIS避雷器内部电位分布和电场分布不可忽视的影响。本研究采用有限元计算软件COMSOL建立了110 kV三相共罐GIS避雷器的电场仿真模型，研究了三相电阻片芯体的电位分布、电场分布。分析了铝垫块布置位置、上端盖罩入深度、三相芯体间距以及三相芯体瞬态电压相位对避雷器电位分布和最大电场强度的影响。研究结果表明：铝垫块布置位置、上端盖罩入深度和三相芯体间距对避雷器电阻片电位分布均有影响 ...

Enhanced Microwave Attenuation via Coupled Ni3ZnC0.7/Ni3InC0.5 Heterogeneous Interfaces
Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT The growing complexity of electromagnetic environments places increasingly stringent demands on microwave absorbers, particularly regarding broadband attenuation, impedance matching in ultrathin configurations, and structural stability. Herein, we propose a dual nonstoichiometric carbide synergistic regulation strategy, in which Ni3ZnC0.7 and ...

Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT Defect engineering plays a crucial role in regulating the active sites and reaction pathways of nanozymes. In this work, oxygen vacancies (Vo) were successfully introduced and stably regulated in ternary CoFeMo layered double hydroxide (CFM LDHs) via a microwave‐assisted hydrothermal strategy, leading to the construction of oxygen‐vacancy‐rich

带电更换1000 kV耐张绝缘子时的工器具和人体电场分布研究
Gaoya dianqi, 2021 利用组合工器具带电更换1 000 kV耐张绝缘子会改变绝缘子串的电压分布、影响带电工作人员体表电场分布,为分析绝缘子串不同位置进行更换作业时的整体电压和电场分布规律,文中根据实际1 000 kV耐张塔输电线路建立了三维模型,利用有限元法进行电场仿真分析;并使用子模型法重点分析了组合工具在不同位置时工具本体的最大电场值,以及人体在不同位置使用组合工具时的体表场强分布。分析结果表明,组合工具越靠近导线端,对绝缘子的电位分布及人体电场分布的影响越大,与没有组合工具短接绝缘子时进行比较,从铁塔端到靠近导线端 ...

Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT The lack of diverse active sites in single‐component catalysts inevitably leads to a competitive adsorption dilemma between 5‐hydroxymethylfurfural (HMF) and OH−, impeding the kinetics of electrocatalytic oxidation of HMF (EC‐HMFOR). Herein, we deliver an interfacial engineering strategy by constructing a rare‐earth metal oxide heterostructure

Gaoya dianqi, 2009 针对800 kV氧化锌避雷器(MOA)的电位分布,笔者从数值仿真和试验两个方面进行分析。首先,采用有限元法及ANSYS分析了无并联电容时800 kV MOA的电位分布,得到了所有氧化锌组件(MOR)的电压偏差和每单元内MOR所占电压的百分比,并同时求出各法兰之间的部分电容和对地电容。并联电容后将MOA的"静电场"问题转化为"电路"问题,用节点电压法求出并联电容后的电位分布和MOR的电压偏差。接下来,采用自行研制的光纤测量系统对800 kV MOA的电位分布进行了实测,得出了流过MOR的电流分布曲线 ...

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Aqueous Zn‐ion batteries (AZIBs) are expected to become one of the most promising candidates for large‐scale energy storage, but are impeded by uncontrollable dendrite growth and parasitic reactions. In this study, we propose a simple mechanical shot‐peening (SP) approach for restructuring commercial Zn foils into highly exposed (002)‐textured

Gaoya dianqi, 2010 采用有限元数值分析法,针对750 kV交流输电线路绝缘子片数及均压环配置,对绝缘子串电位分布进行了计算分析,比较了均压环均压深度、环径、管径及绝缘件介电常数对绝缘子电位分布的影响;对典型配置绝缘子"I"串进行了电位分布的测量研究,并将试验和计算的结果进行了对比分析。研究表明,均压环均压深度及环径对绝缘子电位分布影响较大,均压环管径及绝缘件介电常数对电位分布影响不明显;试验与计算的绝缘子最高分布电压百分比基本一致。
