Estudio comparativo de dos métodos de síntesis para la obtención de polvos cerámicos de ZnO - Pr₂O₃ - CoO

Boletín de la Sociedad Española de Cerámica y Vidrio, 2004
Zinc oxide containing rare earth metal and Cobalt oxide are utilized as raw material to make varistors. Some of systems were found to exhibit non-ohmic current-voltaje characteristics and they are applicable not only for low voltaje devices but also for ...

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 ...

The Study of the Electrical Properties of a Single Grain Boundary in Metal Oxide Varistors

, 1989
Small signal AC and DC responses of a single grain boundary in commercial low voltage Metal Oxide Varistor materials were examined. Two electron traps at the depth 0.16 eV and 0.33 eV below the conduction band edge were characterized using Lump Parameter/
