Problems solved by technology
However, after the damaged tower is restored to its original state, the wind resistance is the same as that of the tower before the damage, so the wind resistance of the tower is still weak, so that the transmission tower is still vulnerable to damage when the next typhoon comes. A tower collapse accident occurred

Embodiment Construction
[0048] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0049] like figure 1 As shown, a flow chart of a method for repairing a transmission tower provided in an embodiment of the present invention includes:
[0050] S11, according to the latest wind zone distribution map of coastal areas, determine the transmission towers falling into the reference wind zone;
[0051] S12, according to the wind speed of the reference wind area and the latest windproof requirements, verify the towers of the transmission towers falling into the reference wind area;
[0052] S13, when the towers of the transmission towers falling into the reference wind zone do not meet the latest windproof requirements, extracting the tower shape parameters of...

The invention relates to the technical field of high-voltage power transmission equipment and discloses a repairing method and device for a power transmission tower. According to the repairing method,the power transmission tower located in a reference wind area is determined according to the newest wind area distributing diagram of a coastal area, and a pole tower of the power transmission towerlocated in the reference wind area is verified according to the wind speed of the reference wind area and the newest anti-wind requirement; when the pole tower of the power transmission tower locatedin the reference wind area does not meet the newest anti-wind requirement, the shape parameters of the pole tower of the power transmission tower located in the reference wind area are extracted, andthe pole tower of the power transmission tower located in the reference wind area is designed and checked on the basis of the newest anti-wind design standard according to the wind speed of the reference wind area, the design parameters and the pole tower shape parameters; and according to the design and the checking effect of the pole tower of the power transmission tower, a reinforced tower designing diagram for repairing the pole tower is generated, the pole tower of the power transmission tower is repaired according to the reinforced tower designing diagram so as to improve the anti-wind capacity of the pole tower of the power transmission tower, and thus the tower collapse accident, occurring when a typhoon disaster comes, of the power transmission tower is avoided.
Description
technical field [0001] The invention relates to the technical field of high-voltage power transmission equipment, in particular to a method and device for repairing a power transmission tower. Background technique [0002] After the typhoon disaster, the transmission towers are the most severely damaged structural main body. These damaged towers are often because they are old iron towers, and the old codes of 79 regulations and 99 regulations are basically used in the design, which leads to the damage of the towers. The wind resistance is weak, which in turn leads to the weak wind resistance of the transmission tower. [0003] At present, the emergency repair method after the typhoon disaster is mainly to restore the original design drawings of the transmission towers directly, so as to ensure the restoration of power supply of the damaged lines in the shortest possible time. However, after the damaged tower is restored to its original state, the wind resistance is the same...
