Gaoya dianqi, 2023 金属氧化物压敏电阻（metal oxide varistor,MOV）广泛应用于各种直流断路器中，用于抑制过电压、系统能量耗散与开断电压建立。受目前加工工艺限制，单MOV阀片通流能力有限，故断路器中多采用多柱并联结构。柱间电流分配不均会导致局部阀片超负荷耗能，造成开断失败甚至设备损坏。文中基于实验测量建立了一种直流开断工况下的MOV电气模型，基于该模型提出了MOV阀片均流选配方法。经实验验证，传统基于雷电冲击测试方法选配的MOV在直流开断工况的均流特性不能完全满足要求 ...

Interaction of nanostructured metal overlayers with oxide surfaces
, 2007 Interactions between metals and oxides are key factors to determine the performance of metal/oxide heterojunctions, particularly in nanotechnology, where the miniaturization of devices down to the nanoregime leads to an enormous increase in the density ...

Stability of Metal-Oxide Varistor Characteristics in Exploitation Conditions
Acta Physica Polonica A, 2009 Wide-spread use of metal–oxide varistors for non-linearity over-voltage protection results in a variety of possible working conditions. It is therefore essential to have a thorough insight into their reliability in various exploitation environments.

Processing of zinc oxide varistors : sources of defects and possible measures for their elimination
, 1997 The processing of ZnO varistors primarily follows the conventional ceramic route. A number of dopants are added to zinc oxide powder to prepare the constituent material and some additional finishing operations are performed for securing the varistor ...
