technical field

The invention belongs to the technical field of power equipment, relates to a lightning protection ground terminal, and is a multifunctional feeder clip applied to a power tower and a communication antenna.

technical background

At present, due to the lack of base station sites for 5G construction, the construction of wireless communication sharing power towers is in full swing to alleviate the high demand for base station density and the pain point of insufficient site sites. When installing communication equipment such as antennas on power towers, lightning protection grounding has become an essential research goal. In the traditional communication tower, the grounding of the feeder is realized by the grounding bar, and the feeder is fixed by the feeder card. In order to reduce the effective length of the core wire of the feeder, thereby reducing the over-induced voltage, the feeder should not be perpendicular to the ground and parallel to the tower body. It needs to be pulled around the tower. The existing feeder card does not perform well in the unified traction of multiple feeders around the tower. The installation is scattered and the fixing effect is not reliable. When the equipment is transferred to the power tower, the strong electric environment increases, and the communication equipment is more necessary. A safe and reliable way of fixing and grounding. At present, the research on the integration of feeder fixation, traction, grounding and protection in common tower construction is relatively blank at home and abroad. The front end of this technology.

SUMMARY OF THE INVENTION

The problem to be solved by the present invention is: under the requirement of the common tower setting of the communication equipment and the power tower, a corresponding device needs to be provided to simultaneously provide fixation, traction, grounding and protection for the communication equipment feeder of the common tower.

The technical scheme of the invention is as follows: a multifunctional feeder clip applied to a power tower with a communication antenna, comprising a feeder fixing component and a grounding row component, the feeder fixing component includes a pole tower hoop and a feeder limit flat steel, the pole tower hoop There is a pair of hoop welding nuts on the outside, and a pair of limit flat steel fastening bolts correspondingly. The feeder limit flat steel is fixed on the tower hoop through the connection between the limit flat steel fastening bolts and the hoop welding nut. The thickness of the hoop welding nut is consistent with the diameter of the feeder wire, and the feeder limit flat steel is used to confine multiple feeders in parallel between the feeder limit flat steel and the tower hoop.

Further, the multifunctional feeder clamp further includes a grounding bar assembly, and the grounding bar assembly includes a grounding bar, and the grounding bar is connected to the pole tower hoop through a pair of angled flat bars.

As a preferred way, the angled flat steel is composed of a vertical flat steel and a horizontal flat steel. The vertical flat steel is provided with an installation hole, and the limit flat steel fastening bolt passes through the installation hole and is connected to the hoop welding nut. , so that the angled flat steel and the feeder limit flat steel are fixed together.

Further, according to the tower height of the power tower and the mounting height of the communication antenna, the feeder fixing group is composed of a multifunctional feeder clip including only the feeder fixing component and a multifunctional feeder clip including the feeder fixing component and the grounding bar component. The feeder is fixed and pulled at different heights.

The multifunctional feeder clip of the present invention is provided with a feeder limit flat steel, and a grounding bar is arranged as required, and the feeder fixing component is combined with the grounding bar component, and the fixing, traction, grounding and protection of the feeder on the power tower are integrated. The common tower construction of communication power provides a convenient and reliable design option, and the use is flexible. For example, when only two grounding bars are required on the tower, only two feeder clips are equipped with grounding bar components, and the rest can be installed without grounding bars. , only the feeder fixing component is set, which plays the role of feeder fixing and saves resources.

Compared with the existing feeder clip, the feeder clip of the present invention can firmly fix multiple feeders at the same time, and ensures that the feeders are arranged neatly. For traction, for example, three feeder clips are set on the upper, middle and lower parts of the tower, and the upper and lower ones are installed southward, and the middle one is installed northward, which can achieve a round of traction around the tower. On this basis, the stable and unified traction around the tower can reduce the effective length of the feeder core wire, thereby reducing the over-induced voltage, and making the equipment safer in the strong electric environment and lightning protection interference.

Compared with the traditional solution, the technical solution provided by the present invention can conveniently limit the feeder to a predetermined position through the feeder limiting flat steel, and the installation is convenient, the feeder is firmly fixed, and the grounding bar is added to allow the fixing device It is connected with the grounding device to form a whole, which is faster and more convenient for production under the premise of safety and reliability. It realizes the integration of fixation, traction, grounding and protection of feeders in the construction of common towers, which can promote the development of wireless communication.

Detailed ways

The present invention provides a multifunctional feeder clip applied to a power tower for installing a communication antenna, comprising a feeder fixing assembly and a grounding row assembly. The feeder fixing assembly includes a tower hoop 1 and a feeder limit flat steel 4. The outer side of the tower hoop 1 A pair of hoop welding nuts 3 is provided, and a pair of limit flat steel fastening bolts 5 are provided correspondingly. 1, the thickness of the hoop welding nut 3 is consistent with the diameter of the feeder line, and the feeder limit flat steel 4 is used to limit multiple feeders in parallel between the feeder limit flat steel 4 and the tower hoop 1. The grounding bar assembly includes a grounding bar 8, and the grounding bar 8 is connected to the tower hoop 1 through a pair of angled flat steels. The multifunctional feeder clamp includes two structures, one is provided with only the feeder fixing component, and the other is provided with the fault and grounding bar components at the same time.
