摘　　要：潜供电弧的自灭时间决定单相重合闸的重合时间和成功率,潜供电弧自灭特性的研究是保证单相重合成功的关键技术。特高压输电线路潜供电弧试验室模拟试验是行之有效的研究方法,根据特高压回路设计可能的潜供电流和恢复电压值,采用试验室单相等价回路进行了相应风速、电压梯度、潜供电流值的无补偿、正常补偿和过补偿情况下的102组(共计2 013次)潜供电弧模拟试验,深入研究了特高压输电线路潜供电弧自灭特性,其结果为确定断路器单相重合闸时间整定值的设计规范提供了科学依据。The auto-reclosing time and the success rate of the single-phase auto-reclosing operation are determined by the extinguishing time of the secondary arc. The extinction characteristic research of the secondary arc is the key technology to guarantee the success of the auto-reclosing operation. Laboratory simulation is an effective method to research the extinction characteristic of secondary arc in ultra high voltage （UHV） transmission lines. According to the secondary arc and the recovery voltage value of the UHV transmission lines, a total of 102 groups amounted to 2013 times of secondary arc simulation experiments with different wind speeds, voltage gradients and secondary arc currents were conducted under compensation-free, normal compensation and compensation conditions. Secondary arc extinction characteristics on UHV transmission lines were investigated, and the results provided a scientific basis for stipulating the design specification of circuit breakers＂ rcclosing time.
