Problems solved by technology

[0008] Therefore, the lightning protection and grounding protection of the shared tower is particularly important, and the lightning protection and grounding system of the original power tower cannot meet the requirements of 5G communication base stations
In terms of lightning protection, the communication antenna can be mounted on different parts of the tower top, tower head, tower body, etc. The original lightning protection system cannot protect antennas in all positions
In terms of grounding, the grounding resistance of the original ground network is required to be less than 30 ohms, while the grounding resistance of the communication system is required to be less than 10 ohms. Obviously, the existing lightning protection grounding level cannot meet the requirements of communication base stations

Embodiment 1

[0075] 1. Lightning protection of shared towers:

[0076] The outdoor lightning wire (needle) protects the antenna at an angle of less than 45°, so the communication base stations, feeders, cable racks and other facilities at the tower head and tower body are all within the protection range of the lightning rod. The lightning rod should be specially equipped with a lightning protection down-conductor. If it is confirmed that the electrical connection of the metal components of the iron tower is reliable, it is not necessary to set a special down-conductor, and the tower body can be used as a grounding conductor. The communication base station at the top of the tower is not within the protection range of the lightning protection wire (needle), so the base station fixed pole needs to be specially equipped with a lightning protection grounding down-lead. One side of the clamp is convenient for the installation of feeder grounding. The down-conductor should be welded with 40mm×4mm...

Abstract

The invention relates to a lightning protection and grounding method for a shared iron tower. According to the mounting position of the 5G communication antenna, lightning protection protection methods are respectively proposed. Down conductor for lightning protection grounding; when the antenna is located in other locations (within the protection range of the lightning rod), the tower body is used as the grounding conductor; and the calculation formula of grounding resistance is optimized, taking into account the horizontal grounding body, vertical grounding body and radial grounding body Based on the existing grounding system of the power tower, a ground grid transformation plan is proposed, that is, a ring grounding device is added on the basis of the original ground grid, and the ring grounding device is on the same level as the original ground grid, and every 3‑5m Welded and connected to each other once, the ring grounding device includes a horizontal grounding body, a vertical grounding body and a radial grounding body, so that the grounding resistance of the shared iron tower can meet the requirements of the power system and the communication system at the same time.

Description

technical field [0001] The invention relates to a lightning protection and grounding method for a shared iron tower, in particular to a lightning protection and grounding system for a shared tower communication base station. It belongs to the technical field of electric equipment. Background technique [0002] At present, our country is in an era of "post-4G" and the beginning of 5G. Compared with the connection between 4G people and people, the application scenarios of 5G have expanded to the connection between people and things, and between things and things, which has a huge market prospect. With the development of society towards intelligence, Internet + and Internet of Things technologies are advancing by leaps and bounds, and all of these require the support of a huge, full-coverage wireless communication network. Compared with 4G signals, 5G signals have comprehensive improvements in speed, delay and other aspects. However, due to the high frequency and short wavele...
