Problems solved by technology

[0004] Based on the existing set of current-limiting grounding devices for electric power and communication sharing towers, there is no electrical connection between the two sets of grounding devices. Equipment and maintenance personnel pose a threat, which will lead to technical problems of damage to communication equipment in serious cases. This invention proposes a complete set of current-limiting grounding device for electric power and communication shared iron towers

Embodiment 1

[0029] refer to Figure 1-4 , a complete set of current limiting grounding device for a power and communication shared iron tower, comprising a mounting frame 4, an iron tower foundation component is fixedly connected on the surrounding inner walls of the mounting frame 4, and a fixing rod is fixedly connected on one inner wall of the mounting frame 4, and the fixing rod A mounting seat is fixedly connected to one end of the mounting seat, a threaded rod 15 is connected to the bottom inner wall of the mounting seat through a bearing, a threaded sleeve 14 is threadedly connected to the outer wall of the threaded rod 15, and the top of the threaded sleeve 14 is fixedly connected with a second bearing platform 8, The inner wall of the second bearing platform 8 is fixedly connected with return springs 16 distributed at equal distances. One end of the return springs 16 is fixedly connected with a support pad. The outer wall of the opposite side of the support pad is provided with a ...

Embodiment 2

[0040] refer to Figure 5 , a complete set of current limiting grounding device for power and communication sharing iron tower, compared with Embodiment 1, this embodiment also includes that a rain shield 27 is arranged on the top outer wall of the mounting frame 4, and the rain shield 27 is set as a hollowed round table structure.

[0041] When in use, the rain shield 27 arranged on the top of the mounting frame 4 has a circular truncated hollow structure, which effectively protects the grounding connection 21, the current limiting component 19 and the fuse component 20 under the rain shield 27 to avoid raining. , rainwater penetrates into electrical equipment.

Abstract

The invention discloses a complete set of current limiting grounding device for a power and communication shared iron tower. Since there is no electrical connection between the two sets of grounding devices, when there is an overvoltage condition on a power line, a higher potential exists between the power iron tower and the grounding device of a communication base station. Poor, it is easy to pose a threat to equipment and maintenance personnel, and in severe cases, it will lead to damage to communication equipment. The following solution is now proposed, including an installation frame. The surrounding inner walls of the installation frame are fixedly connected with iron tower foundation components. The installation frame A fixing rod is fixedly connected to the inner wall of one side. The invention solves the problem that the communication equipment is damaged due to the potential difference between the two independent grounding systems in the case of overvoltage of the power line. When the limit is reached, the fuse component will disconnect the grounding wire to protect the safety of the equipment of the communication base station.

Description

technical field [0001] The invention relates to the technical field of power transmission line construction, in particular to a complete set of current limiting grounding devices for electric power and communication sharing towers. Background technique [0002] Currently, transmission lines are often affected by lightning strikes during the rainy season. In order to avoid line tripping accidents caused by lightning strikes, in the process of line design and construction, grounding bodies are usually installed on the legs of transmission towers to introduce lightning current into the ground. In my country's transmission line projects, ring-type, ray-type and other grounding bodies are usually used. And generally, the ring-shaped and ray-shaped grounding body needs to occupy a large area around the transmission tower. Therefore, during installation, first excavation work is required to fix the transmission line tower, and then a secondary excavation is performed around the tr...
