Single-loop power transmission crossing tower and crossing system
The invention discloses a single-loop power transmission crossing tower which comprises a tower body, a wire cross arm is arranged in the middle of the tower body, one side of the two side faces, perpendicular to the trend of a single-loop wire, of the tower body is a crossing gear, the other side of the two side faces perpendicular to the trend of the single-loop wire is a non-crossing gear, and a ground wire hanging point is arranged on the side, facing the non-crossing gear, of the top of the tower body so that communication ground wires of the non-crossing gear can be connected. A middle ground wire hanging point is arranged at the position, corresponding to the middle of the tower body part and facing one side of the crossing gear, of the wire cross arm so that a communication ground wire can be switched to one side of the crossing gear, and a lightning protection support is arranged on the tower top. Compared with a non-crossing gear, the height of the ground wire in the crossing gear is remarkably reduced, so that the ground wire and the wire in the gear are approximately located on the same horizontal plane, the vertical distance between the conductor and the ground wire in the crossing gear is greatly reduced to be minimum through the arrangement mode, and the crossing line meets the safety distance with the crossed line; the safety distance between a crossing line wire and the ground is easier to meet, and the feasibility of power transmission line cross crossing is effectively improved.
本发明公开了一种单回路输电穿越塔，包括塔身，塔身中部设置有导线横担，塔身垂直单回路导线走向的两侧面一侧为穿越档另一侧为非穿越档，塔身顶部朝向非穿越档一侧设置有地线挂点，以使对非穿越档的通信地线连接，导线横担对应塔身部分中部位置且朝向穿越档一侧设置有中部地线挂点，以使对通信地线转接至穿越档一侧，塔顶上设置有避雷支架。本发明穿越档内地线高度与非穿越档相比显著降低，使档内的地线和导线近似处于同一水平面，这种设置方式极大压缩了穿越档内导、地线间竖向距离至最小，使穿越线路满足与被穿越线路安全距离的同时，更易于满足穿越线路导线对地面的安全距离，有效提高输电线路交叉穿越的可行性。
