摘　　要：计算了预期接触电压与户内配电箱到插座的配线距离变化之间的关系,以及预期接触电压与入户电表箱到户内配电箱位置的配线距离变化之间的关系,分析了预期接触电压与配线距离间的变化关系,从而探讨住宅建筑中的局部等电位联结的作用局限性。The relationships between the expected contact voltage and the change of wiring distance were calculated from the different indoor distribution box to the socket outlets and from the household meter box to the indoor distribution box. The changing relationship between the prospective touch voltage and wiring distance was analyzed. The effect limitation of local equipotential bonding was discussed in residential building.

关 键 词：住宅建筑 局部等电位联结 预期接触电压 相保阻抗
