摘　　要：紧凑型线路施工和普通输电线路一样 ,在紧线观测弛度中总是存在误差 ,三相导线弛度不可能完全一致 ,安装相间间隔棒后 ,在安装点使其三相间距相等 ,必然导致各相导线荷载、张力、弛度发生变化 ,达到新的平衡。文章探讨了紧凑型线路安装相间间隔棒后的导线荷载分配量、导线张力、弛度的计算方法。The construction of compact-type transmission line is the same as construction of conventional lines.The errors always occur in observing the sag during line tensioning and the sags of conductors in three phases can not be completely identical.After installation of phase to phase spacers the equal distance among three phases at the installing point will certainly result in variation of load,tension and sag of each phase conductor to reach the new balance.The paper discusses the calculation method for conductor load distribution,tension and sag after installation of phase to phase spacers on compact type transmission lines.
