核电高压开关柜抗震性能分析

Gaoya dianqi, 2019
开关柜的绝缘性能破坏会影响电气设备的正常运行。在核电等特殊领域的高压设备,会受地震影响造成绝缘性破坏继而影响整柜的正常工作,后果十分严重。通过计算和分析,模拟仿真出开关柜整柜在地震作用下的变形有重要意义。文中以Workbench作为仿真平台,采用高性能并行计算机作为计算平台,以振型分解反应谱法为理论基础,对核电1E级F-C交流金属封闭开关设备柜体及主要部件进行了整体抗震分析。评估其整体结构的抗震性能,并且对后续的结构的优化设计提供重要参考。

交流GIS用紧凑型盆式绝缘子沿面绝缘特性研究

Gaoya dianqi
盆式绝缘子作为气体绝缘金属封闭开关设备（GIS）中核心元件，在保证绝缘强度前提下，为了减小设备体积，减少SF6气体使用量，文中以工程实际GIS用盆式绝缘子为研究对象，基于沿面电场优化开展了紧凑型盆式绝缘子方案设计，重点研究了盆子中心导体处倾斜角度、高压屏蔽电极根部到盆子中心导体距离及盆式绝缘子侧壁角度对切向场强的影响。仿真结果表明，紧凑型盆式绝缘子凹、凸侧面切向场强呈现单双峰结构变化，凸侧面最大切向场强大幅上升，整体最大切向场强降低5.5%；中心导体处倾斜角度为6°～8°时，凹面侧最大切向场强取得极小值。
