Gaoya dianqi, 2013 为改善架空输电线路下方工频电场分布,在线路下方架设屏蔽线。考虑线路档距、弧垂等因素的影响,建立高压架空输电线路工频电场三维仿真计算模型,研究架设屏蔽线改善高压输电线路下方工频电场的效果,分析讨论了屏蔽线架设高度、横向位置、间距、根数等对线路下方及表面工频电场影响的规律和特征。结果表明:架设屏蔽线能够有效改善导线下方空间工频电场;屏蔽线架设高度、横向位置对屏蔽效果影响明显,存在最佳布置位置;屏蔽线间距对其屏蔽效果有一定影响;屏蔽线根数越多,效果越好,但逐渐趋于平缓;架设屏蔽线会增大分裂导线表面电场强度。

Filling Uniformity of AgNPs in EMI Shielding Patch Regulated by Surface Morphology
Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Silver nanoparticles (AgNPs) are extensively employed for electromagnetic interference (EMI) shielding owing to their remarkable conductivity, and are commonly incorporated into polymer matrices. Therefore, the uniformity of the AgNP distribution within the polymer matrix is a crucial factor that affects the EMI shielding performance.

Gaoya dianqi, 2019 采用Ansys软件计算分析了采用单屏蔽和双屏蔽结构的两种550kV SF6充气套管的电场分布。分析表明,采用单屏蔽结构的与采用双屏蔽结构的550 kV SF6充气套管,均符合设计要求。经绝缘试验验证,两种结构设计的套管均通过了试验。但双屏蔽结构的SF6充气套管,结构较复杂,性价比不及单屏蔽结构的SF6充气套管。

Gaoya dianqi, 2020 电缆传输线模型具有广泛的应用场景,比如电磁暂态仿真、电缆局部放电诊断等。电缆的传输线参数受到电缆接地金属屏蔽层结构的影响。为了分析这种影响,研究了3种屏蔽结构:①整层接地铜屏蔽;②多股铜导线构成的接地屏蔽;③多股铜导线和铅层构成的双层接地屏蔽结构。首先构建了前两种屏蔽结构电缆的二维模型,有限元仿真获得的传输线参数和实测结果的对比验证了仿真的正确性,在此基础上对比分析了3种屏蔽结构对传输线参数的影响。为了解决二维模型无法表征多股铜导线螺旋结构的问题,针对多股铜导线屏蔽电缆构建了三维模型 ...
