Tower head of direct-current three-loop crossing tower
The invention provides a direct-current three-loop crossing tower head which is arranged at the top end of a tower body and comprises an octagonal tower window, a pair of first cross arms and a pair of second cross arms. First rod units inclined downwards are arranged in the middle of the first cross arm, and the two first rod units are symmetrically arranged; the end parts of the first cross arm are respectively provided with a ground wire suspension point; the first rod units of the first cross arm are respectively provided with a first loop wire suspension point; the vertical symmetry axis of the octagonal tower window is provided with second loop wire suspension points which are distributed up and down; the end parts of the second cross arms are respectively provided with a third loop wire suspension point; according to the tower head, the three-circuit direct-current power transmission lines are designed to be arranged in an upper-layer triangular mode and a lower-layer triangular mode, compared with a traditional three-circuit direct-current vertical line hanging mode, the height of the tower head of the crossing tower is reduced through staggered arrangement of wire hanging points, and therefore the lightning protection performance and stability of the crossing tower are improved.
本发明提供一种直流三回路跨越塔塔头，设置在塔身顶端，包括八边形塔窗、一对第一横担和一对第二横担；第一横担中部设有向下倾斜的第一杆单元，且两个第一杆单元对称设置；第一横担的端部分别设有地线悬挂点；第一横担的第一杆单元分别设有第一回路导线悬挂点；八边形塔窗的竖直对称轴上设有呈上下分布的第二回路导线悬挂点；第二横担的端部分别设有第三回路导线悬挂点；该塔头将三回直流输电线路设计为上、下两层三角形排列，相比于传统三回直流垂直挂线方式，该设计通过导线悬挂点的交错排列，降低了跨越塔塔头高度，从而提高跨越塔的防雷性能以及稳定性。
