| 摘 要： | 耦合地线的作用是增大耦合系数,增大雷电流向杆塔两侧的分流,从而提高送电线路的耐雷水平,降低跳闸率。本文推导出具有避雷线及耦合地线的送电线路耐雷水平计算公式,对在实际工程中分析、评价耦合地线在防雷中的作用有着十分重要的意义。

| Abstract: | Coupled ground wires on transmission line increase the coefficient of coupling and branc the lightning current to side poles, so that the bias becomes more lightning-resistant and the specific tripout rates are reduced. A formula is derived in the paper for calculating lightning bearihg capacity of transmission line with lightning-shielding wires and coupled ground-wires. This for mula is very useful in analysing and appraising the actions of coupled ground-wires on pretection of lightning current in practical engineering. |
