A linear tower

Abstract

The invention provides a linear tower and belongs to the field of transmission equipment. The linear tower comprises a tower body, ground wire cross arms, guide wire cross arms, ground wire hanging points, ground wire pull cables, guide wire hanging points and guide wire pull cables. The safety level of ground wire cross arm lower plane main materials and the safety level of guide wire cross arm lower plane main materials are both lower than the safety level of the tower body, so that the ground wire cross arms or the guide wire cross arms are damaged earlier than the tower body on the extreme climatic conditions; when the ground wire cross arm lower plane main materials are damaged, the ground wire pull cables drive ground wires to release the torque of load relative to the tower body; when the guide wire cross arm lower plane main materials are damaged, the guide wire pull cables drive guide wires to release the torque of load relative to the tower body. Therefore, the tower collapse accident is prevented; the difficult in restoration and reconstruction is reduced; the reconstruction working period is shortened; the probability of strand breakage or pull breakage of guide wires or ground wires is reduced; the time needed by power grids for returning to normal work is reduced; the potential safety hazards occurring because of pull breakage of the guide wires are reduced.

Description

technical field [0001] The invention relates to the field of power transmission equipment, in particular to a linear tower. Background technique [0002] Straight line tower is a type of tower commonly used in transmission lines. In power transmission lines, straight line towers are generally used to bear the load of ground wires and wires. [0003] Existing linear towers include tower body, wire cross arm and ground wire cross arm, tower body, wire cross arm and ground wire cross arm are all made of angle steel, wire cross arm and ground wire cross arm are fixed on the tower body, tower body , The safety level of the conductor cross-arm and the ground wire cross-arm are equal. [0004] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0005] Since the safety level of the tower body, wire crossarm and ground wire crossarm of the existing straight tower is equal, when subjected to extreme...
