摘　　要：针对大型地下变电站空间相对狭窄的特点,提出交流耐压试验配合灵敏局放测量的地下变电站GIS现场绝缘试验方案,其中GIS耐压试验采用SF6气体绝缘的试验电抗器实现.试验表明,该方案可行性强、有效性高,适合在大型地下变电站中现场推广应用.On account of the relatively narrow space of underground substations,a test scheme which includes AC withstand voltage test and high sensitivity measurement of partial discharge is proposed in this paper.SF6 insulated reactor is applied in GIS withstand voltage test.Test results show that the test scheme has highly feasibility and effectiveness.It is suitable to apply in underground substation tests.
