Embedded-hanging warning device without abrasion for cables of electric power system

Abstract

The invention provides an embedded-hanging warning device without abrasion for cables of electric power system, and belongs to the field of direction boards of overhead lines. The embedded-hanging warning device comprises a direction board, an internal ball and an external ball, the internal ball is an internal ball body which is connected with the top of the direction board. The top of the external ball is fixed to a cable through a fixing device, the internal ball is arranged in the external ball, the external ball is provided with an opening where the connecting rod passes through. The embedded-hanging warning device does not wear the cable, and make the cable 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.
