摘　　要：研制了一种具有对称结构的单微隙放电管 ,研究了它的电特性。结果表明这种对称微隙放电管的耐冲击电流能力大于 15 0 0 A、极间电容小于 1p F、冲击击穿电压约 40 0 V。它可以克服非对称单微隙放电管在直流击穿电压对称性和稳定性方面的缺陷。In Chinese A symmetrical single microgap surge absorber is presented Its characteristics are measured The results indicated that the symmetry and stability of DC spark over voltage are excellent The impulse discharge current is more than 1 500 A, the electrostatic capacitance is less than 1 pF and the impulse spark over voltage is about 400 V (6 refs )
