Power system cable wear-free embedded suspension and warning device

Abstract

The invention provides a wear-free embedded suspension and warning device for cables in a power system, which belongs to the field of warning signs for overhead lines and includes a sign, an inner ball and an outer ball. The top is connected; the top of the outer ball is fixed on the cable through a fixing device, the inner ball is located in the outer ball, and the outer ball is provided with an opening for the connecting rod to pass through, which will not wear the cable or drive the cable to swing.

Description

technical field [0001] The invention provides a wear-free embedded suspension and warning device for cables in a power system, which belongs to the field of warning signs for overhead lines. Background technique [0002] Due to the relationship between thermal expansion and cold contraction of high-voltage overhead lines, the line is often not erected in a straight line, but is erected in an arc between two towers to prevent it from being broken during the process of cold contraction. The distance between the lowest point of the cables and the ground is often very low. When larger equipment passes by at night, it is likely to encounter high-voltage cables, resulting in dangerous accidents. Therefore, power supply management and control companies often use hanging rings to The signboard is hung on the overhead line. When the signboard is blown by the wind, it will swing back and forth.

[0002] Due to the relationship between thermal expansion and cold contraction of high-voltage overhead lines, the line is often not erected in a straight line, but is erected in an arc between two towers to prevent it from being broken during the process of cold contraction. The distance between the lowest point of the cables and the ground is often very low. When larger equipment passes by at night, it is likely to encounter high-voltage cables, resulting in dangerous accidents. Therefore, power supply management and control companies often use hanging rings to The signboard is hung on the overhead line. When the signboard is blown by the wind, it will swing back and forth. The purpose of using the hanging ring is to avoid the fixed connection between the signboard and the overhead line. When the wind blows, the signboard will drive the overhead line to swing and cause danger. , so that the hanging ring is constantly rubbing against the cable, and the long-term friction will wear the cable ring, and the drivers of large equipment at night cannot see the signs on the overhead line clearly.
