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。

温度对SF₆/CF₄混合气体尖板放电特性的影响

Gaoya dianqi
气体绝缘电气设备使用SF6/CF4混合气体可以避免SF6气体液化，适合在极寒地区应用。为获得设备内部存在尖端放电缺陷时SF6/CF4混合气体的绝缘性能受温度的影响，采用尖板电极模拟缺陷尖端放电，开展SF6/CF4混合气体在0.1~0.7 MPa气压范围和-50~20 ℃温度范围的工频放电实验。结果表明，不同温度下SF6/CF4混合气体的击穿电压随气压升高均出现先升高—再降低—再升高的驼峰趋势；但随着温度降低，驼峰峰值处的击穿电压随温度降低出现降低趋势，而在非驼峰峰值处的击穿电压随温度降低而基本不变 ...

基于可调谐激光技术的C₄F₇N气体中微水含量检测装置的研制

Gaoya dianqi
C4F7N气体是一种代替SF6的新型电气设备环保绝缘气体。C4F7N气体作为绝缘气体在高压设备中使用时，与SF6设备具有类似的问题，气体的质量影响着设备的正常运行。尤其当C4F7N气体中水分含量超标时，极易引起设备放电降低设备绝缘性能等问题的出现。因此研发针对使用C4F7N气体的运维检测设备就显得尤为重要。文中主要研究可调谐激光红外吸收光谱法对C4F7N中微水含量的定量检测技术。研究了可调谐激光的光谱理论、谐波检测原理和水分的红外吸收特性，介绍了在C4F7N为背景气体的情况下对微水检测精度的影响 ...
