Description

Technical Field

[0001] The utility model relates to a hanging point device, in particular to a hanging point device for an overhead ground wire of an iron tower. Background Art

[0002] Overhead ground wires, also known as lightning arresters, refer to wires that are directly connected to the earth on high-voltage and ultra-high-voltage lines. Due to the shielding of overhead ground wires on wires and the coupling between wires and overhead ground wires, the chance of lightning directly striking the wires can be reduced. When lightning strikes a tower, part of the lightning current can be diverted through the overhead ground wire, thereby reducing the potential on the top of the tower and improving the lightning resistance level;

[0003] The existing overhead ground wire hanging point device serves as an important auxiliary tool for connecting the ground wire, and plays a vital role in the use of high-voltage lines. It can fix the installation path of the overhead ground wire so that the overhead ground wire will not be inserted into other places. It is also more convenient for workers to quickly find the source of the line problem and know where the line has a problem, so as to repair the line as soon as possible and nip the safety hazard in the bud. However, this hanging point device only has a round hole to limit the position of the ground wire, but does not have any protective measures. Since the ground wire is a relatively long line, only the fixed round hole cannot prevent the line from being violently shaken by strong winds in the air, and it is easy to connect with other lines and hang on other hanging point devices nearby, causing the ground wire to break and short-circuit. Therefore, there is still a great safety hazard. Utility Model Content

At the same time, it is also more convenient for workers to quickly find the source of the line problem and know where the line has a problem, so as to repair the line as soon as possible and nip the safety hazard in the bud. However, this hanging point device only has a round hole to limit the position of the ground wire, but does not have any protective measures. Since the ground wire is a relatively long line, only the fixed round hole cannot prevent the line from being violently shaken by strong winds in the air, and it is easy to connect with other lines and hang on other hanging point devices next to it, causing the ground wire to break and short-circuit. Therefore, there is still a great safety hazard.
