Prediction on electrical insulation synergistic effect of gas mixture based on dimer microscopic descriptors

AIP Advances
Buffer gas is often mixed with insulation gas to reduce the greenhouse gas consumption. Mixing of different gases could lead to the synergistic effect of electrical insulation strength. In a previous effort, breakdown experiments were used for buffer gas

C₄F₇N/CO₂环保型气体操作冲击绝缘特性研究

Gaoya dianqi, 2021
SF6是当前在气体绝缘设备中应用最广泛的绝缘气体,其全球增温潜势极大,C4F7N/CO2混合气体因为是一种极具发展前景的可代替SF6的环境友好型气体倍受关注。目前针对C4F7N/CO2混合气体在实际应用场景中的操作冲击绝缘特性研究较少,文中实验中搭建了操作冲击绝缘试验平台,研究了不同气压下3种C4F7N气体摩尔比例的C4F7N/CO2中252 kV电压等级GIL的操作冲击绝缘特性,并设置0.5 MPa SF6作为对照组。分析放电数据发现:在同一C4F7N/CO2气体压力下 ...

环保型C4F7N混合气体生物安全性及应用可行性评估

Gaoya dianqi, 2023
近年来，以全氟异丁腈(C4F7N)为核心的环保绝缘气体凭借优良的电气性能获得了广泛关注。尽管C4F7N在新一代气体绝缘设备中获得了初步应用，但是评估C4F7N的职业及环境健康暴露风险是确保其大规模安全应用的前提。文中通过亚急性吸入毒性试验(28天)、延长一代生殖毒性试验和骨髓嗜多染红细胞微核试验，综合评估了C4F7N混合气体的生物安全性及应用可行性。试验结果表明，大鼠亚急性吸入C4F7N气体后观察到的无可见有害作用水平(NOAEL)为3 693μL·L-1，靶器官主要为肺脏；C4F7N气体对孕鼠母体 ...

切向电场主导下C₄F₇N/CO₂混合气体中环氧复合材料表面电荷积聚特性及机理研究

Gaoya dianqi, 2023
气固界面的电荷积聚问题是诱发沿面闪络的重要原因，而当前C4F7N/CO2混合气体中电荷积聚特性的相关研究还不够充分。为研究C4F7N/CO2混合气体中表面电荷积聚特性及机理，本文通过指型电极构建极不均匀电场，测量了环氧复合材料在C4F7N/CO2混合气体中的表面电荷分布特性；进一步的，为理清表面电荷来源及迁移特性，测量了冲击电压下C4F7N/CO2混合气体中材料表面电位，比较了附加背板电极前后的表面电荷分布。研究表明，C4F7N/CO2混合气体与SF6中表面电位分布形态相似 ...
