国际上基于数值仿真计算金属氧化物避雷器的研究进展

Dianci bileiqi, 2018
系统综述了基于数值仿真计算技术在金属氧化物避雷器（metal-oxide surge arresters,MOA）研究中的应用发展。共分3个方面:1)基于等效电路模型的数值仿真计算;2)基于电、机械与热的两或多物理量（场）耦合的金属氧化物电阻片（metal-oxide surge varistor,MOV）数值仿真计算;3)整只MOA的电场、温度场或多物理场耦合的数值仿真计算。对于MOV的建模和仿真计算,将来主要的努力方向是改进数学计算模型,以便可以描述ZnO晶界与时间和温度相关的特性 ...

DC-SSCB Snubber for Electric Propulsion Ships With Effective Surge Voltage Reduction and Fast Dissipation of Fault Current Energy

IEEE Access
This paper proposes a snubber circuit for SSCB that performs voltage clamping operation in two stages to reduce surge voltage. The surge voltage is suppressed in the first stage using a MOV with low operating initiation and clamping voltages.
