摘　　要：对典型棒-板间隙在不同间距、不同淋雨工况下,开展了正极性直流和工频电压下的放电试验研究。结果表明,与标准气象条件相比,淋雨条件将降低棒-板空气间隙的正极性直流击穿电压值和工频击穿电压值。可为超高压、特高压输电线路塔窗空气间隙的工程选择提供试验依据。To study the discharge performance of typical rod-plate gap under different gap and rain conditions, several experiments of standard operation wave and lightning wave were carried out. Different with standard meteorological conditions, the DC and AC positive will breakdown voltage of rod-plane air gap decreases under rain conditions. In the construction of EHV or UHV transmis- sion line tower, this paper can provide test basis for the select of tower window air gap.
