摘　　要：电气化铁路接触网隔离开关引线长度的选取影响线索间电气绝缘距离以及连接、固定处机械荷载性能,传统施工方法依靠经验、手感等容易造成引线长度选取不当,将影响电气化铁路安全稳定运行。本文基于接触网服役特性以及隔离开关、引线安装特征,结合工程环境工况,提出引线长度计算方法、步骤,推导出引线长度计算式,并给出工程计算示例,为电气化铁路接触网隔离开关引线长度的选取提供了详细的理论依据。The selection of lead wire length for OCS disconnector of electrified railway affects the electrical insulation distance between wires and the mechanical load performance of the connection point and fixing point.Traditional construction methods are relying on experience and hand feeling,and liable to cause improper selection of lead wire length,which will affect the safe and stable operation of electrified railway.Based on the service characteristics of OCS and the installation characteristics of disconnectors and lead wires,combined with the engineering environmental conditions,the paper puts forward the method and procedures for calculation of lead wire length,deduces the calculation formula for calculation of lead wire length,and gives an engineering calculation example,which provides a detailed theoretical basis for the selection of lead wire length for OCS disconnectors of electrified railway.
