500 kV紧凑型同塔双回输电线路带电作业人体体表电场分布特性研究
Gaoya dianqi, 2017 电场防护是带电作业安全技术研究的重要内容,关系到作业人员的生命安全。文中分析了500 k V紧凑型同塔双回输电线路的结构特点,建立了作业人员体表场强仿真模型,计算了典型工况下不同作业点人员的体表场强分布,同时分析了塔型和线路运行方式对人员体表场强分布的影响。计算结果表明:同一运行方式下,地电位作业时,直线塔作业人员的头部和脚部场强较耐张塔高出约4倍;等电位作业时,耐张塔作业人员的头部场强较直线塔高243.2 k V/m,手部较之高出1.9倍。同一塔型作业时 ...

Gaoya dianqi, 2023 文中基于电磁场基本理论，建立了开关柜工频磁场数学模型，采用有限元法对开关柜的磁感应强度进行了计算，分析了壳体、壳体厚度和磁导率等对开关柜磁感应强度分布和屏蔽效能的影响，并研究了开关柜柜外母排长度对磁感应强度分布的影响，结果表明：开关柜外壳和隔板对工频磁场具有明显的屏蔽作用，增大壳体磁导率和厚度均可提高开关柜整体的屏蔽效能，但当壳体磁导率大于1 000和厚度超过3 mm时，屏蔽效能增长幅度较小；柜外母排长度对开关柜周围磁场分布影响较小，但对柜体顶部磁场分布的影响较大 ...

Conservation Biology, Volume 40, Issue 1, February 2026.Abstract As the global protected area (PA) network expands to meet international targets, it is important to assess whether traditional reliance on public land will suffice for projected PA growth or whether other tenures, such as Indigenous or pastoral lands, may increasingly contribute.

Dianci bileiqi, 2017 盆式绝缘子是GIS设备较为重要的绝缘件,在实际运行中,其绝缘性能与电场分布关系密切。从一起盆式绝缘子事故分析入手,对盆子烧蚀产物和故障气体进行成分分析。分析结果表明:盆子局部高场强导致电弧闪络产生大电流,从而引起盆子表面烧蚀和SF6气体成分变化。基于此,通过理论解析方法从金属屑、金属突出物和绝缘介质内部存在气泡3种绝缘缺陷对局部高场强进行理论解释,并得到其局部场强增强系数。随后建立盆式绝缘子三维电场仿真计算模型,得到其电场分布规律,发现盆式绝缘子表面场强分布不均匀,易在中心导体附近形成局部场强集中 ...

A Mini Review of Scientific Designs of Dynamic Responsive Fluids in Battery Technologies
Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Dynamic responsive fluids are emerging as transformative elements in the evolution of battery technologies, marking a pivotal shift from static passive designs toward systems that actively sense and adapt to their operating environments. By integrating dynamic responsive fluids, batteries can interact with both internal and external stimuli in

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Thermodynamic prediction‐driven phase‐field kinetic simulation, with experimental verification, is utilized to explore the high‐performance cobalt–nickel based (CoNi‐based) superalloys. The roles of aluminum (Al) in microstructural evolution and precipitation kinetics of ordered L12‐γ′ strengthened Co–Ni–xAl superalloys are revealed. The alloy

Dianci bileiqi, 2013 我国冬季混合凇冰灾频繁并严重威胁输电线路安全运行;覆冰后的导线表面会形成雨凇和雾凇的混合体,尖锐的冰柱会畸变冰面电场分布,进而使导线表面场强增大;为研究混合凇覆冰对导线表面场强的影响规律,在小型人工气候室内完成了对LGJ-185/25绞线混合凇覆冰后的参数测量,并根据混合凇形态建立电场分布模型,利用有限元法对导线覆冰后的表面场强进行计算。结果表明:混合凇形成的冰柱尖端会增大导线表面场强;随着覆冰程度的增加,导线表面场强会继续增大但速度却逐渐减慢并最终趋于饱和 ...

Dianci bileiqi, 2023 耐张塔是高海拔地区最为复杂的塔型，其附近电场计算较为困难，给基于电场分析的带电作业进入路径的选取带来较高难度。笔者选取耐张塔作为研究对象，首先仿真分析了作业区域内人体体表电场强度，接着以所受平均最大场强最小以及进入路径最短作为双重优化目标，进行基于遗传算法多目标优化，得到进入路径最优解。然后对该路径下的电位转移电流进行仿真计算，基于结果对安全防护提出要求。考虑到目标作业导线离横担距离小于塔身的这一工况，提出了一种变绳长的等电位进入方法，该法具有作业人员平均体表场强最小，安全性更好的优点。最后开展现场实测，

International Journal of Urban and Regional Research, Volume 50, Issue 1, Page 191-220, January 2026.Abstract Henry George advocated for capturing land value increases for public ends. The active approach of public authorities organizing and financing land development can help capture higher land value increases, as Hartman and Spit indicate. However, this approach hardly happens in developing countries, where the coalition of private developers and ...
