Power transmission tower maintenance method

Abstract

The invention discloses a power transmission tower maintenance method, and relates to the technical field of power equipment maintenance. The power transmission tower maintenance method comprises the steps that spacers of a to-be-maintained tower are sequentially dismantled, and temporary reinforcing stay wires are arranged for a middle-layer cross arm main material and a lower cross arm bottom main material of the to-be-maintained tower and adjacent towers of the to-be-maintained tower; pulleys are hung on the adjacent towers, the conducting wires and the ground wires are arranged in sliding grooves of the pulleys, and idle wheel temporary anchors of the adjacent towers are installed; through the main material of the to-be-maintained tower and the pulleys, grounding wire split phases are sequentially lowered to the lowest point and fixed to the tower body main material of the to-be-maintained tower, and the tower material of the to-be-maintained section of the to-be-maintained tower is dismounted; and a new tower material is assembled for the to-be-maintained section of the to-be-maintained tower, and maintenance is completed. According to the power transmission tower maintenance method, the tower materials of the power transmission tower can be rapidly replaced without replacing the ground wires, the line power supply reliability is guaranteed, various huge losses caused by too long line power failure are avoided, only part of the tower material is replaced, the problems of too high cost, too long time and the like of overall replacement of the power transmission tower are solved, and potential safety hazards can be eliminated in time.

Description

technical field [0001] The invention relates to the technical field of power equipment maintenance, in particular to a maintenance method for a power transmission tower. Background technique [0002] The transmission tower is an important part of the transmission line. It is mainly composed of a square pyramid-shaped tower structure welded by angle steel. Due to changes in geological conditions and the foundation of the iron tower, the transmission tower will be tilted, which has brought great potential safety hazards to the safety of the transmission line. The deformation of the tower material of the transmission tower will cause the tower to be tilted due to uneven force, and there will be high risks such as tower collapse, disconnection, and power grid paralysis, which will seriously affect the safe operation of the line. But at the same time, the weight of the transmission tower is relatively large, and the tower is connected with a high-voltage transmission line, which...

Problems solved by technology

Due to changes in geological conditions and the foundation of the iron tower, the transmission tower will be tilted, which has brought great safety hazards to the safety of the transmission line.

The deformation of the tower material of the transmission tower will cause the tower to be tilted due to uneven force, and there will be high risks such as tower collapse, disconnection, and power grid paralysis, which will seriously affect the safe operation of the line

But at the same time, the weight of the transmission tower is relatively large, and the tower is connected with a high-voltage transmission line, which brings great difficulty to the tilt correction of the transmission line tower. How to quickly repair the deformed tower material of the transmission tower has become Eliminate one of the difficulties in the safety of transmission lines
