Power system cable wear-free suspension suspension and warning device

Abstract

The invention provides a power system cable wear-resistant suspension type hanging and alarming device and belongs to the field of overhead line alarm sign boards. The power system cable wear-resistant suspension type hanging and alarming device comprises a sign board, a solid ball and a hollow ball, wherein the solid ball is a solid sphere and connected with the top of the sign board via a connection rod; the hollow ball top is fixed on a cable via a fixing device; the solid ball is placed in the hollow ball; the hollow ball is provided with an opening, through which the connection rod can pass, so no wear is caused to the cable and the cable can be prevented from swinging.

Description

technical field [0001] The invention provides a wear-free suspension 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 power cable and the ground is often very low. When larger equipment passes by at night, it is likely to encounter high-voltage power cables, resulting in dangerous accidents. Therefore, power supply management and control companies often Hang the sign on the overhead line through the hanging ring. When the sign 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 sign...

[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 power cable and the ground is often very low. When larger equipment passes by at night, it is likely to encounter high-voltage power cables, resulting in dangerous accidents. Therefore, power supply management and control companies often Hang the sign on the overhead line through the hanging ring. When the sign 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 sign and the overhead line, and make the sign drive the overhead line when the wind blows The swing causes danger, which makes the hanging ring constantly rub against the power cable. Long-term friction will wear the ring of the power cable, and drivers of large equipment at night cannot see the signs on the overhead line clearly.
