摘要

根据实体模型

采用有限元分析软件对紧凑运行方式下220 kV金属氧化物避雷器建立3-D模型

进行电位和电场分布计算。计算结果显示

由于阻波器距避雷器较近

使得避雷器对高电位的杂散电容增大

避雷器的电位分布变得更加均匀

因此紧凑环境下只要保证设备之间有足够的安全距离

避雷器在此环境下运行是安全可靠的。

Abstract

Based on the special structure of MOA

a 3-D model of 220 kV MOA under compact operation mode is established.The electric potential and field distribution of MOA was calculated using ANSYS numerical analysis software.The result shows that because of the metal shell of wave trapper is close to MOA

which makes the MOA’s stray capacitance becomes larger

and its electric potential distribution becomes more equalized.For this reason

so long as there has enough safe distance between the equipments.MOA is safe and reliable under this condition.
