多种冲击电流下金属氧化物压敏电阻动态模型准确性分析

Gaoya dianqi
为研究IEEE模型和Pinceti模型对金属氧化物压敏电阻（metal-oxide varistor，MOV）的仿真准确性，以额定电压为150～750 V的6种MOV为对象，理论和试验分析了不同幅值4/10 μs、8/20 μs雷电冲击电流和30/60 μs操作冲击电流下的残压及吸收能量。结果表明，在IEEE模型参数确定中，随操作冲击电流幅值的增大，非线性电阻参考电压取值增大但电感取值减小；在残压预测中，IEEE模型误差为2.6%，较Pinceti模型误差4.6%更准确；在MOV吸收能量估算中 ...

Partial oxidation of ethane to syngas over nickel-based catalysts modified by alkali metal oxide and rare earth metal oxide

, 1999
The catalytic activity, thermal stability and carbon deposition of various modified NiO/gamma-Al2O3 and unmodified NiO/gamma-Al2O3 catalysts were investigated with a flow reactor, XRD, TG and UVRRS analysis.
