Gaoya dianqi, 2019 随着特高压交流工程建设的不断开展,越来越多特高压变电站将建设在低温地区。由于特高压开关设备普遍采用SF6气体绝缘,在低温地区使用会存在低温液化问题,降低设备运行稳定性,提升电网运行风险,需采取措施提高设备耐受低温能力。基于设备重要性的考虑,对于1 100 kV GIS,宜采用户内布置方式。对于户外使用的1 100 kV出线套管和分支母线可采用降低气压的方法降低气体液化温度。对于其他电压等级的GIS设备,可在设备外壳加装加热装置,按一定程序对设备气室加热,保证绝缘和灭弧介质SF6的状态稳定 ...

Dianci bileiqi, 2016 110 k V气体绝缘变电站（GIS）由于其优异的电气综合性能在国内得到了广泛应用,运行中隔离开关（DS）和断路器（CB）的分合闸操作以及单相接地故障等均可能引起快速暂态过电压（VFTO）,对电力设备造成威胁。以110 k V小型化GIS变电站为计算模型,利用电磁暂态程序（EMTP）对多种接线方式下DS、CB分合闸操作和分支母线单相接地故障产生的VFTO进行三相仿真计算,获得了不同工况下VFTO电压幅值、波形、陡度、频率等特性参数。计算分析了分支母线长度、变压器入口电容等因素对VFTO的影响 ...
