摘要
简述了气体绝缘金属封闭开关设备(GIS)中暂态地电位升高(TGPR)产生的原理及其等值计算模型。利用电磁暂态程序(EMTP)计算了金属氧化物避雷器(MOA)对GIS中快速暂态过电压(VFTO)和暂态地电位升高(TGPR)的抑制效果。仿真计算结果表明,MOA不仅可以抑制VFTO,而且也可较有效地抑制TGPR。
The principle and equivalent computhag model of TGPR were described in the paper. Using Electro-magnetic Transient Program （EMTP）, the suppressions of VFTO and TGPR by using metal-oxide arrester （MOA） were computed. It shows that MOA can suppress not only VFTO, but also TGPR effectively.
