Traditional guy towers are mostly suspension cable guy towers, which require the use of suspension insulator strings to hang the conductors to meet different conductor arrangement requirements. The suspension insulator strings are mostly V-shaped, that is, the tops of two suspension insulators are spaced apart and the suspension ends are connected to each other to form a conductor hanging point, making the corridor wide, increasing the floor space of the guy tower, and prone to phase-to-phase flashover under wind deviation conditions.

The first reinforcing plates 231 are connected to the hanging plate 220 and the connecting plate 210 at the same time. The two first reinforcing plates 231 are respectively arranged on the second plate surfaces of the two flat plates 211 and extend along the length direction of the flat plates 211. The plate 231 is perpendicular to the side surface of the hanging plate 220 and the second surface of the flat plate 211. A second reinforcing plate 232 is also connected between the two first reinforcing plates 231, so that the connection between the hanging plate 220 and the connecting plate 210 is more stable, ensuring the overall mechanical strength of the first connecting hardware 20. A construction plate 233 is connected to the plate surface of the second reinforcing plate 232 away from the hanging plate 220.

At the same time, the first reinforcing plate 231, the second reinforcing plate 232 and the construction plate 233 of the same structure are symmetrically arranged on the other side of the hanging plate 220. By arranging reinforcing plates on both sides of the hanging plate 220 and connecting the hanging plate 220 and the flat plate 211 at the same time, the first connecting fitting 20 has a symmetrical structure as a whole, ensuring that the overall structure of the first connecting fitting 20 is stable and the overall force is more reasonable.

当第一连接组件200用于形成中相导线挂接点时，参阅图6，第一连接金具20关于平面P1对称设置，即连接板210、挂线板220、第一加强板231、第二加强板232、施工板233均关于平面P1对称设置，使得横担组件100关于平面P1对称，从而横担组件100挂设导线101后受力均衡，结构稳定，此时平面P1为竖直平面，施工板233沿竖直方向设置便于吊装施工。When the first connecting component 200 is used to form a hanging point for the middle phase conductor, referring to FIG6 , the first connecting fitting 20 is symmetrically arranged about the plane P1, that is, the connecting plate 210, the hanging plate 220, the first reinforcing plate 231, the second reinforcing plate 232, and the construction plate 233 are all symmetrically arranged about the plane P1, so that the cross arm component 100 is symmetrical about the plane P1, so that the cross arm component 100 is subjected to balanced force after hanging the conductor 101, and the structure is stable.

当第一连接组件200用于形成一侧的边相导线挂接点时，参阅图7，第一连接金具20的连接板210关于平面P1对称设置，由于横担组件100自中部向两侧逐渐向上方延伸设置，此时平面P1需与竖直平面呈一定夹角设置使得连接板210中的其中一个平板211高于另一个平板211设置，进而使得第二绝缘子组件1120高于第一绝缘子组件1110设置。第一加强板231、第二加强板232仍关于平面P1对称设置，挂线板220靠近第二绝缘子组件1120一侧的尺寸大于其靠近第一绝缘子组件1110一侧的尺寸，起到加强机械强度的作用，施工板233仍沿竖直方向设置便于吊装施工。When the first connection assembly 200 is used to form a side phase conductor hanging point, refer to FIG7 , the connection plate 210 of the first connection fitting 20 is symmetrically arranged about the plane P1. Since the cross arm assembly 100 is gradually extended upward from the middle to both sides, the plane P1 needs to be arranged at a certain angle with the vertical plane so that one of the flat plates 211 in the connection plate 210 is arranged higher than the other flat plate 211, thereby making the second insulator assembly 1120 higher than the first insulator assembly 1110. The first reinforcement plate 231 and the second reinforcement plate 232 are still symmetrically arranged about the plane P1. The size of the hanging plate 220 near the second insulator assembly 1120 is larger than the size near the first insulator assembly 1110, which plays a role in strengthening the mechanical strength. The construction plate 233 is still arranged in the vertical direction for easy hoisting construction.

其中，相邻两个绝缘子组件110之间的夹角根据实际工程应用中的电气间隙要求设计，且横担组件100中的各个第一连接组件200的连接板210的V形内侧板面的夹角角度可以相同，也可以不同，以适应各个绝缘子组件110之间不同的排布方式。The angle between two adjacent insulator assemblies 110 is designed according to the electrical clearance requirements in actual engineering applications, and the angles of the V-shaped inner plate surfaces of the connecting plates 210 of each first connecting assembly 200 in the cross arm assembly 100 can be the same or different to adapt to each Different arrangements of the insulator assemblies 110 .

In one embodiment, the straight line formed by the first vertex end and the second vertex end is parallel to the horizontal plane. In other embodiments, the straight line formed by the first vertex end and the second vertex end may also form a certain angle with the horizontal plane, which is not limited here.

两个第二绝缘子组件1120的一端通过第一连接组件200与第一绝缘子组件1110固定连接，第一连接组件200上设有挂线金具串，用于挂设导线，即第一绝缘子组件1110的第一顶点端和第二顶点端形成两处挂线点，同时第一绝缘子组件1110的第三顶点端也设有挂线金具串，用于形成一处挂线点，继而第一绝缘子组件1110的三个顶点端形成三处挂线点，用于挂设三相导线。One end of the two second insulator components 1120 is fixedly connected to the first insulator component 1110 through the first connecting component 200. The first connecting component 200 is provided with a hanging wire string for hanging the wire, that is, the first vertex end and the second vertex end of the first insulator component 1110 form two hanging wire points, and the third vertex end of the first insulator component 1110 is also provided with a hanging wire string for forming a hanging wire point, and then the three vertex ends of the first insulator component 1110 form three hanging wire points for hanging three-phase wires.

其中，绝缘子组件110可以包括一个绝缘子，也可以包括若干个相互间隔平行设置的绝缘子，只要使得横担组件100满足挂设导线的受力要求即可。横担组件100可以包括两个直线形的第二绝缘子组件1120和一个三角形的第一绝缘子组件1110，也可以包括其他数量的直线形的绝缘子组件和三角形的绝缘子组件。以及，横担组件100可以设置为一组，也可以沿竖直方向间隔设置为多组，根据输电线路要求进行设计，在此不作限制。例如横担组件沿竖直方向间隔设置为两组，每组横担组件上均形成三处挂线点，从而可以用于挂设双回路三相导线。Among them, the insulator assembly 110 may include one insulator, or may include a plurality of insulators spaced apart and arranged in parallel with each other, as long as the cross-arm assembly 100 meets the force requirements for hanging conductors.

本申请的拉线塔10上的横担组件100通过采用若干依次连接的绝缘子组件110，仅需采用挂线金具串悬挂导线，相比于传统自立铁塔和拉线塔，降低了呼高，解决了相间的风偏闪络问题，且压缩了相间距离，在保持相同的杆塔使用高度情况下，提升了线路的传输效率，改善了受力；同时减小了边相导线与塔身的距离使得塔材、基础及施工成本都降低，增加了边相导线与中相导线的线间距，进而能够降低无线电干扰等因素的影响，压缩输电线路走廊宽度。The cross arm assembly 100 on the guyed tower 10 of the present application adopts a plurality of insulator assemblies 110 connected in sequence, and only needs to adopt a hanging wire string to suspend the conductor. Compared with the traditional self-supporting iron tower and the guyed tower, the height is reduced, the problem of wind deflection flashover between phases is solved, and the phase distance is compressed. While maintaining the same tower height, the transmission efficiency of the line is improved and the stress is improved; at the same time, the distance between the side phase conductor and the tower body is reduced, so that the tower material, foundation and construction costs are reduced, and the line spacing between the side phase conductor and the middle phase conductor is increased, thereby reducing the influence of factors such as radio interference and compressing the width of the transmission line corridor.
