| 摘 要： | 针对GIS生产及维修过程中可能存在的固定或自由微粒会使GIS正常运行时局部场强过高而导致耐压水平降低的问题,借助高准确度的ANSYS有限元法软件分别研究了固定微粒在靠近252 KV GIS绝缘子的高压导体上和接地外壳内侧时GIS的电场分布情况,发现两种情况下的电势等值线分布情况变化不大,但电场强度分布情况明显不同,计算结果对研究GIS内部微粒污染所致击穿电压降低及局部放电有一定意义。

| Abstract: | The electric field of 252 kV GIS including fixed particle on high voltage conductor and low-voltage conductor is analyzed by using the finite method and ANSYS.Analysis results show that potential is same,except fixed partial area,but electric field intensity is different under both conditions.These results are of significance for the study on breakdown voltage and partial discharge of GIS. |
