| 摘 要： | 本文研究气体绝缘变电所的过电压。对某些典型接线的GIS变电所的雷电过电压,文章采用电磁暂态计算程序进行了计算。在计算的基础上提出限制这些过电压以及绝缘配合的一些初步建议。有一种类型的过电压可能是对GIS来说要求更为严格的,即在主回路中操作引起的某些高频操作过电压。对GIS的保护来说,氧化锌避雷器比带间隙避雷器被认为更有效。

Overvoltages and Insulation Coordination of GIS Substations |
| |
| Abstract: | This paper deals with overvoltages induced in the gas insulated substation (GIS),For lightning overvoltages in the typical GIS substations,the paper gives the detailed results calculated by Electromagnetic Trasients Program.On the base of the calculation some suggestions for protection from these overvoltages and insulation co-ordination are proposed.There is a kind of overvoltages which may be rather critcal for GIS,that is the switching surges with high frepuency produced by operation in the main circuit.zinc-Oxide arresters have been found more effective than conventional surge arresters. |
