Abstract

The power line in the mining-affected area can automatically adjust the stroke connecting plate, which belongs to the technical field of power system equipment, especially the equipment used in the mining-affected area of ​​the power line and the straight pole tower in the geologically bad area. The technical problem to be solved is to provide an automatic The device for adjusting the offset of the hanging string adopts the following technical scheme: the connecting plate can automatically adjust the stroke of the power line in the mining affected area, the upper part of the connecting plate body is provided with a size mark, the lower part is provided with a pulley groove for placing pulleys, and special connecting hardware The top is connected to the pulley through connecting bolts and the special connecting hardware is located under the connecting plate body. The bottom of the special connecting fitting can be connected with the connecting hardware; It is equipped with a special connecting hardware identification and indicating device, and the invention is applied to the linear pole tower in the area affected by the mining of the power line and the geologically bad area.

Description

technical field [0001] A power line in a mining-affected area can automatically adjust a stroke connecting plate, which belongs to the technical field of electric power system equipment, and in particular relates to equipment used in linear poles and towers in the mining-affected area of ​​the power line and the geologically bad area. Background technique [0002] The tower tilt caused by the mining affected area and the poor geological area occurs from time to time, and the suspension string connecting the supporting ground wire and the tower changes with the inclination of the tower, causing the force on the ground wire to be greater than the design tension. After the tower in the bad area is tilted, the primary measure to ensure the safe operation of the power line is to release the tension of the ground wire and adjust the suspension clamp so that the inclination value of the suspension clamp of the ground wire is within the range specified in the regulations. At present...
