However, the repair time required for tower collapse is far greater than the repair time required for broken lines, and tower collapse is likely to cause chain effects (that is, when a transmission tower collapses, it will cause an impact on the coupled wires on other transmission towers connected to the transmission tower. , and when a transmission tower collapses, the position and force of the wire between the transmission tower and the transmission tower connected to it will change, resulting in an imbalance in the coupling wires on other transmission towers connected to the transmission tower Tension, which leads to the collapse of other transmission towers connected to the transmission tower), so when the collapse of the tower is serious, it may lead to the paralysis of power supply in a large area, causing major economic losses

The embodiment of the invention discloses a power transmission tower, and relates to the communication technology field. The power transmission tower can be protected when the power transmission tower excesses load in various conditions to reduce the probability of generation of tower fall accidents. A lead is erected on the power transmission tower, wires are pulled upwards from two different positions of the lead to one erection point on a power transmission tower body, and the pulling wires from one of the two different positions to the erection point are respectively provided with overload protection devices which are fractured when the tension on the lead is changed. The embodiment provided by the invention is suitable for the power transmission tower.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular to a power transmission tower. Background technique [0002] Transmission lines (including transmission towers and conductors) are subjected to harsh natural conditions such as wind, rain, and ice during long-term work in the field. A wire break occurs, and the unbalanced tension or the impact of the wire break when the wire is broken can easily cause the tower to fall. In addition, in the transmission line with multiple splits and large spans (that is, the transmission line with two splits or more and a span of 100 meters or more), when the conductor is coupled to the transmission tower, the wind load on the conductor (ie The pressure generated by the air flow on the engineering structure, the size of the wind load is proportional to the square of the wind speed) is very large, it is easy to cause uneven force on the tower of the transmission t...
