摘要
研究表明,虽然SF_6—CO_2混合气体在均匀电场中的击穿强度稍逊于同样混合比的SF_6—N_2混合气体,但在不均匀电场中的击穿强度、特别是在雷电冲击电压下的击穿强度,却优于SF_6—N_2.此外,SF_6—CO_2在气膜复合绝缘中的局部放电特性也优于SF_6—N_2混合气体.
Although the breakdown strength of the SF6-CO2 gas mixture is slightly lower than that of the corresponding SF6-N2 gas mixture in a uniform field, it is superior to the SF6-N2 in non -uniform fields especially under lightning impulses. Furthermore, the SF6-CO2 gas mixture is superior to the SF6-N2 mix-ture in respect of partial discharge characteristics in the gas/film insulation.
