Dianci bileiqi, 2014 为了研究垂直接地体发生故障后对暂态接地阻抗的影响,笔者以接地体表面有细缝和局部腐蚀两种状态模拟故障接地体。运用时域有限差分（FDTD）法,通过Matlab编程实现对垂直接地体发生不同故障类型和故障点到接地体入地端的距离与暂态接地阻抗的变化规律的分析。分析结果表明:垂直接地体表面有细缝和局部腐蚀时暂态阻抗大于正常时的值;故障点和垂直接地体入地端之间的距离与暂态阻抗值的变化量成反比关系;在雷电流快速泄流的过程中故障接地体暂态阻抗的变化最显著。研究结论为防雷接地设计,接地体腐蚀状态检测提供了理论依据和实践参考。

Gender Dimensions of Support for Local Policy: Resident, Policymaker, and Policy Gender
Policy Studies Journal, EarlyView.ABSTRACT There is a well‐established triadic relationship between satisfaction with public services, trust in leaders, and policy support in developed democracies. This study takes a novel approach by considering how gender is associated with the strength and direction of these connections, an element underexplored in the literature.

Dianci bileiqi, 2017 利用CDEGS仿真计算了典型杆塔接地网的接地电阻,首先对比了柔性石墨接地体与圆钢、锰铜在工频接地及冲击接地性能的区别,结果表明,柔性石墨接地体的工频接地电阻略高于圆钢,但由于其非磁性,较弱的趋肤效应使其冲击接地电阻低于圆钢,因此,柔性石墨接地体具有良好的防雷接地特性。然后,以广东佛山典型输电线路中柔性石墨接地体示范应用工程为例,介绍了有关柔性石墨接地体的实际工程施工工艺及技术,为其他类似的工程及试验提供参考依据。

Dianci bileiqi, 2020 目前在输电线路杆塔接地网中应用广泛的接地材料包括镀锌扁钢、锰铜等传统金属材料,但在高频电流条件下传统金属接地体存在明显的集肤效应,进而影响其散流特性,新兴的非金属石墨复合接地材料因其"导电不导磁"的特性有效改善了上述问题。针对石墨复合接地体的结构进行优化进而制备了扩径石墨复合接地体,利用有限元仿真分析其集肤效应,并采用CDEGS软件仿真分析传统金属接地体、实心石墨复合接地体及扩径石墨复合接地体在不同频率、不同土壤情况、不同直径条件下的散流特性。研究结果表明,在高频高阻条件下 ...

Dianci bileiqi, 2023 山区输电线路杆塔所处位置通常土壤电阻率高且空间有限，故散流效果差，降阻比较困难。针对这些问题，本研究使用CDEGS软件设计了立体均压环结构接地体，在不同激励电流类型、土壤电阻率、接地体深度和水平射线长度情况下，进行了冲击特性的分析。仿真结果表明：在工频电流和雷电流作用下，该接地体都能够具有良好的均压和散流效果。相同土壤电阻率下，立体均压环接地体冲击接地电阻比传统圆环形接地体冲击接地电阻至少可较低8.9%,最大跨步电压至少可降低16.0%,在高土壤电阻率下，降低幅度增大 ...
