ZnO压敏电阻稳定性的研究

Research on the Stability of ZnO Varistor

本文从含ＴｉＯ２低压压敏材料入手，研究了ＨＮＯ３处理及热处理工艺对ＺｎＯ压敏电阻器性能的影响，并讨论了交流冲击下的电压稳定性。通过处理，其非线性系数α上升，漏电流ＩＬ下降，尤其耐冲击能力大有改观。

With the low voltage ZnO varistor materials contaning TiO 2, the influence of HNO 3 treatment and heat treatment on ZnO varistor properties has been investigated in this paper. After treating, the non linearity coefficient α of ZnO varistor rises and the leakage current decreases,especially, the ability of absorbing surge energy has been improved greatly.
