Angular tower for power transmission line in icing area
The invention discloses an angular tower for a power transmission line in an icing area. The angular tower comprises a tower body and a cross arm, wherein the cross arm comprises two cross arm bodieswhich are sequentially and fixedly arranged on the upper section of the tower body from top to bottom, each cross arm body is of a truss structure and comprises a truss girder which forms an airflow loop and a reinforcing rod, the truss girders are sequentially connected end to end to form an isosceles trapezoid, and the reinforcing rods are fixedly arranged between the bottom edges and the waistsof the isosceles trapezoid; and the truss girders are hollow pipes, fan for forming airflow circulation and electric heating wires for heating gas are arranged inside the truss girders, and insulating outer layers are arranged on the surfaces of the truss girders. When the angular tower operates in the extremely cold icing area, ice on the cross arm can be effectively removed in time, the mechanical load of the cross arm is reduced, the ice flashover and lightning stroke prevention capacity of the iron tower is improved, and the safe, stable and energy-saving operation of a power transmissionsystem is guaranteed.
本发明公开了一种用于覆冰区输电线路的转角铁塔，包括塔身和横担，所述横担包括两个由上至下依次固定设置在塔身上段的横担体，所述横担体为桁架结构包括形成气流回路的桁架梁及加强杆，所述桁架梁首尾顺次连接形成等腰梯形，所述加强杆固定设置于等腰梯形的底边与腰之间；所述桁架梁为中空管，内部设置有形成气流循环的风机及对气体进行加热的电热丝，所述桁架梁表面上设置有绝缘外层。本发明在极寒覆冰区运行时可以及时有效地去除横担上的冰，减轻横担的机械荷载，提高铁塔防冰闪和雷击的能力，保障了输电系统安全、稳定、节能的运行。
