Embodiment 1

[0029] refer to Figure 1-4 , a complete set of current-limiting grounding device for an electric power and communication shared iron tower, including a mounting frame 4, the tower foundation components are fixedly connected to the inner walls around the mounting frame 4, and a fixed rod is fixedly connected to the inner wall of one side of the mounting frame 4, and the fixed rod One end of the mounting seat is fixedly connected with a mounting seat, the bottom inner wall of the mounting seat is connected with a threaded rod 15 through a bearing, the outer wall of the threaded rod 15 is threaded with a threaded sleeve 14, and the top of the threaded sleeve 14 is fixedly connected with a second bearing platform 8, The inner wall of the second load-bearing platform 8 is fixedly connected with return springs 16 equidistantly distributed, and one end of the return springs 16 is fixedly connected with a support pad, and a signal receiver 7 is arranged on the opposite side outer wall...

Embodiment 2

[0040] refer to Figure 5 , a complete set of current-limiting grounding device for electric power and communication sharing iron tower. Compared with Embodiment 1, this embodiment also includes that a weather shield 27 is arranged on the top outer wall of the installation frame 4, and the weather shield 27 is set as a hollowed-out circular platform. structure.

[0041] During use, the weather shield 27 that is arranged on the top of the installation frame 4 is a hollow structure in the shape of a circular cone, which effectively protects the grounding connection 21, the current limiting assembly 19 and the fuse assembly 20 under the rain shield 27, so as to avoid the rain in the process of raining. , rainwater seeps into electrical equipment.

Abstract

The invention discloses a complete current-limiting grounding device for an electric power and communication shared iron tower, and aims to solve the problems that two sets of grounding devices are not electrically connected, and when an overvoltage condition exists in an electric power line, a relatively high potential difference exists between an electric power iron tower and a communication base station grounding device so as to easily threaten equipment and maintainers and cause communication equipment damage in case of serious conditions. According to the technical scheme, the complete current-limiting grounding device comprises a mounting frame, wherein iron tower foundation assemblies are fixedly connected to the inner walls of the periphery of the mounting frame, and a fixed rod is fixedly connected to the inner wall of one side of the mounting frame. According to the invention, the problem that communication equipment is damaged due to potential difference between two independent grounding systems under the condition of overvoltage of a power line is solved, meanwhile, the current limiting device is installed on the grounding connection line on the inner wall of a fixing frame, and when grounding current exceeds a limiting value, a fusing assembly disconnects the grounding connection line, so that the equipment operation safety of the communication base station is protected.

Description

technical field [0001] The invention relates to the technical field of transmission line construction, in particular to a complete set of current-limiting grounding device for an electric power and communication shared iron tower. Background technique [0002] Currently, transmission lines are often affected by lightning strikes during the rainy season. In order to avoid tripping accidents caused by lightning strikes on the line, during the design and construction of the line, a grounding body is usually installed on the legs of the transmission tower to guide the lightning current into the ground. In my country's transmission line engineering, ring-type, radial-type grounding bodies are usually used. And the general annular and radial grounding body needs to occupy a large area around the transmission tower. Therefore, during installation, it is first necessary to carry out an excavation work to fix the transmission line tower, and then carry out secondary excavation aroun...
