35kV single circuit compact high-strength electric pole
The invention discloses a 35kV single circuit compact high-strength electric pole. The 35kV single circuit compact high-strength electric pole comprises a three-stage tip pulling pole, a trough-type wire cross arm, a V-shaped wire insulator chain and a ground wire bracket, wherein the three-stage tip pulling pole comprises a bottom electric pole, a middle electric pole and a top electric pole; a protection angle of a ground wire to a wire is alpha, and the angle range of alpha is greater than 11 degrees and less than or equal to 18 degrees. A swing angle of a wire hanging line is zero degree,the accident rate of line wire caused by high wind, such as discharge to a pole tower and short circuit of the wire in gear can be greatly decreased; the corridor resource required by the line is less; the protection angle of the ground wire to the wire is alpha, and the angle range of alpha is greater than 11 degrees and less than or equal to 18 degrees; and the lightning stroke trip accident rate of the line is reduced, thus the accident rate of a power grid caused by lightning stroke is decreased, and the incidence of the lightning stroke accident of the line is decreased.
本发明公开了一种35kV单回路紧凑型高强电杆，具有：三段式拔梢杆，三段式拔梢杆包括底部电杆、中部电杆、以及顶部电杆；槽型导线横担，V形导线绝缘子串，地线支架，其中地线对导线的保护角为α，其中α的角度范围：11°＜α≤18°。使其导线挂线处摇摆角为零度，可大大减少线路导线因大风而引起的对杆塔放电、档中导线短路等事故率；线路所需走廊资源占用少；其中地线对导线的保护角为α，其中α的角度范围：11°＜α≤18°；降低线路雷击跳闸事故率使得电网因雷击引起的事故发生率降低，使得线路雷击事故的发生率降低。
