Abstract

本发明提供一种电力杆塔共享系统,该系统包括电力杆塔装置和通信装置。由于杆塔本体上的避雷线和基站机房顶部的接闪器均连接到杆塔接地网,因此,杆塔本体和基站机房受到雷击时,避雷线和接闪器接收到雷击产生的电流,并将雷击电流传输至杆塔接地网,进而通过杆塔接地网的接地设置将雷击电流传输至大地。又由于避雷线和接闪器均未连接至通信接地网,且杆塔接地网和通信接地网之间设有电绝缘层,因而,杆塔接地网和通信接地网之间产生电气隔离,杆塔接地网接收到的雷击电流不会传输至基站机房,进而不会传输至基站机房内部的弱电设备,以达到保护弱电设备的目的。本发明提供的电力杆塔共享系统结构简单,具有较高的电流传导效率以及较强的实施性。

Description

一种电力杆塔共享系统A power tower sharing system

技术领域technical field

本发明涉及电力技术领域,尤其涉及一种电力杆塔共享系统。The invention relates to the field of electric power technology, in particular to a power pole and tower sharing system.

背景技术Background technique

共享技术已深入到我们生活的方方面面,如共享单车、共享汽车、共享充电宝以及共享雨伞等,并给我们的生活带来了较大便利。伴随共享技术的迅猛发展,电力杆塔共享技术逐渐受到重视。Sharing technology has penetrated into all aspects of our lives, such as shared bicycles, shared cars, shared power banks, and shared umbrellas, and has brought greater convenience to our lives. With the rapid development of sharing technology, power tower sharing technology has gradually received attention.

与普通杆塔相比,电力杆塔具有运行中带电、塔身结构复杂多样、电磁干扰强以及雷击风险高等特点,因而在电力杆塔的共享发展中存在诸多问题。电力杆塔共享中需要加装较多的设施设备,且加装的设施设备多为弱电设备,如变压器、互感器、避雷器等电力一次设备。在雷电天气下,在雷击产生的故障电流流入弱电设备的过程中,电力杆塔接地网上的电位抬升。当形成较高电压时,会对连接至电力杆塔接地网上的弱电设备反击放电。由于弱电设备的耐受过电压能力远远小于电力杆塔及其接地网在雷击情况下产生的数千伏特电压,因而弱电设备在雷击作用下易发生损坏。另外,雷击过程中会产生瞬变电磁脉冲,从天线安装位置下引至弱电设备的二次电缆在瞬变电磁脉冲作用下能够产生感应过电压,且感应过电压的幅值能够高达数千伏特。数千伏特的电压同样也能够造成弱电设备的损坏。Compared with ordinary towers, power towers have the characteristics of being charged during operation, complex and diverse tower structures, strong electromagnetic interference, and high risk of lightning strikes. Therefore, there are many problems in the shared development of power towers. In the sharing of power poles and towers, more facilities and equipment need to be installed, and most of the installed facilities and equipment are weak current equipment, such as transformers, transformers, lightning arresters and other primary power equipment. In lightning weather, the potential on the grounding grid of the power tower rises when the fault current generated by the lightning strike flows into the weak current equipment. When a higher voltage is formed, it will counter-discharge the weak current equipment connected to the grounding grid of the power tower. Since the overvoltage withstand capability of weak current equipment is far less than the thousands of volts generated by power towers and their grounding grids under lightning strikes, weak current equipment is prone to damage under lightning strikes. In addition, transient electromagnetic pulses will be generated during the lightning strike, and the secondary cables leading from the antenna installation position to the weak current equipment can generate induced overvoltage under the action of the transient electromagnetic pulse, and the amplitude of the induced overvoltage can be as high as several thousand volts . Thousands of volts can also cause damage to weak electrical equipment.

由此,电力杆塔的共享发展中应首先防止雷击,进而确保弱电设备的安全运行。Therefore, in the shared development of power towers, lightning strikes should be prevented first, so as to ensure the safe operation of weak current equipment.

具体实施方式Detailed ways

请参考附图1,附图1示出了本发明实施例提供的电力杆塔共享系统的结构示意图。由附图可知,本发明实施例提供的电力杆塔共享系统包括电力杆塔装置01和通信装置02。电力杆塔装置01为用于电力传输的装置,通信装置02为用于放置移动基站设备的机房,其内部设置有无线基站设备、传输设备以及电源设备等弱电设备11。Please refer to FIG. 1 . FIG. 1 shows a schematic structural diagram of a power tower sharing system provided by an embodiment of the present invention. As can be seen from the drawings, the power tower sharing system provided by the embodiment of the present invention includes a power tower device 01 and a communication device 02 . The power tower device 01 is a device used for power transmission, and the communication device 02 is a computer room for placing mobile base station equipment.

具体地,电力杆塔装置01包括杆塔本体1和杆塔接地网2。杆塔本体1为架设输电线路的部件。杆塔接地网2为杆塔埋于地下一定深度处的多个金属接地极以及由导体连接多个金属接地极而形成的网状结构,其主要用于将电流导入大地。为使杆塔接地网2将通过杆塔本体1的电流导入大地,杆塔本体1和杆塔接地网2相连接,且杆塔接地网2接地设置。Specifically, the power tower device 01 includes a tower body 1 and a tower grounding grid 2 . The tower body 1 is a component for erecting a power transmission line. The tower grounding grid 2 is a plurality of metal grounding electrodes buried in a certain depth underground by the tower and a network structure formed by connecting the plurality of metal grounding electrodes with conductors, which is mainly used to guide current into the earth. In order to make the tower grounding grid 2 lead the current passing through the tower body 1 to the ground, the tower body 1 and the tower grounding grid 2 are connected, and the tower grounding grid 2 is grounded.

进一步,杆塔本体1的顶端设有避雷线3和通信天线4。避雷线3通常为铁质或铜质等金属材料,其顶端连接避雷针。避雷线3与杆塔本体1内的金属材料相连接,由此,避雷线3、杆塔本体1和杆塔接地网2依次相连接。在雷雨季节时,避雷线3将雷电雷击杆塔本体1产生的雷击电流通过杆塔本体1、杆塔接地网2导入大地。通信天线4为实现数据传输的线路。为实现电力杆塔装置01和通信装置02之间的数据传输,通信天线4通过通信电缆5连接至通信装置02,并连接至通信装置02内部的弱电设备11。另外,沿通信电缆5的架设方向,杆塔本体1上还设有多个绝缘子10,且通信电缆5设置于绝缘子10上。绝缘子10为绝缘体,具有电绝缘作用。当杆塔本体1受到雷击时,在绝缘子10的电绝缘作用下,能够有效隔绝通信电缆5和杆塔本体1,进而减少流经杆塔本体1的雷击电流对通信电缆5的反击以及降低高电压内引风险,以确保正常通信。Further, the top of the tower body 1 is provided with a lightning protection wire 3 and a communication antenna 4 . The lightning conductor 3 is usually made of a metal material such as iron or copper, and the top of the lightning conductor is connected to the lightning rod. The lightning protection wire 3 is connected with the metal material in the tower body 1 , whereby the lightning protection wire 3 , the tower body 1 and the tower grounding grid 2 are connected in sequence. During the thunderstorm season, the lightning protection wire 3 guides the lightning current generated by the lightning strike to the tower body 1 through the tower body 1 and the tower grounding grid 2 into the ground. The communication antenna 4 is a line for realizing data transmission. In order to realize data transmission between the power tower device 01 and the communication device 02 , the communication antenna 4 is connected to the communication device 02 through the communication cable 5 , and is connected to the weak current equipment 11 inside the communication device 02 . In addition, along the erection direction of the communication cable 5 , a plurality of insulators 10 are also arranged on the tower body 1 , and the communication cable 5 is arranged on the insulator 10 . The insulator 10 is an insulator and has an electrical insulating effect. When the tower body 1 is struck by lightning, under the action of the electrical insulation of the insulator 10, the communication cable 5 and the tower body 1 can be effectively isolated, thereby reducing the counterattack of the lightning current flowing through the tower body 1 to the communication cable 5 and reducing the high voltage internal lead risk to ensure proper communication.

通信装置02包括基站机房6、接闪器7以及通信接地网8。接闪器7位于基站机房6的顶部,其作用与避雷线3的作用基本相似。在本发明实施例中,接闪器7包括相连接的接闪网71和接闪杆72。接闪网71为排布于基站机房6顶部的网状金属材料。接闪杆72为排布于基站机房6顶部边角处的金属杆,其作用与避雷针相似。接闪器7与杆塔接地网2相连接,以便于当基站机房6受到雷击时,雷击产生的雷击电流通过接闪器7传输至杆塔接地网2,进而通过杆塔接地网2导入大地。进一步,由于雷击产生的雷击电流的电流值较大,因而本发明实施例中,接闪器7将雷击电流通过接地引下线12传输至杆塔接地网2。通信接地网8位于基站机房6的下方,且通信接地网8接地设置。The communication device 02 includes a base station room 6 , an air-termination device 7 and a communication grounding grid 8 . The lightning receptor 7 is located on the top of the base station room 6 , and its function is basically similar to that of the lightning protection wire 3 . In the embodiment of the present invention, the air-termination device 7 includes an air-termination net 71 and an air-termination rod 72 which are connected to each other. The lightning net 71 is a mesh metal material arranged on the top of the base station room 6 . The lightning rod 72 is a metal rod arranged at the top corner of the base station room 6, and its function is similar to that of a lightning rod. The air-termination device 7 is connected to the tower grounding grid 2, so that when the base station room 6 is struck by lightning, the lightning current generated by the lightning strike is transmitted to the tower grounding grid 2 through the air-termination device 7, and then leads to the earth through the tower grounding grid 2. Further, since the current value of the lightning current generated by the lightning strike is relatively large, in the embodiment of the present invention, the lightning receptor 7 transmits the lightning current to the tower grounding grid 2 through the grounding down conductor 12 . The communication grounding grid 8 is located below the base station room 6, and the communication grounding grid 8 is grounded.

进一步,基站机房6内设有多个弱电设备11,如控制设备、传输设备以及电源设备等。为实现电力杆塔装置01和多个弱电设备11之间的通信,通信天线4通过通信电缆5分别连接至多个弱电设备11。弱电设备11在使用过程中,可能会出现过电流或过电压的现象,过电流或过电压会导致弱电设备11发生一定程度的损坏。为防止过电流或过电压损坏弱电设备11,多个弱电设备11还分别与通信接地网8相连接,以通过接地设置的通信接地网8将过电流或过电压导入大地。Further, the base station room 6 is provided with a plurality of weak current equipment 11, such as control equipment, transmission equipment, and power supply equipment. In order to realize the communication between the power tower device 01 and the plurality of weak current devices 11 , the communication antenna 4 is respectively connected to the plurality of weak current devices 11 through the communication cable 5 . During the use of the weak current device 11 , the phenomenon of overcurrent or overvoltage may occur, and the overcurrent or overvoltage may cause the weak current device 11 to be damaged to a certain extent. In order to prevent the weak current equipment 11 from being damaged by overcurrent or overvoltage, a plurality of weak current equipments 11 are also connected to the communication grounding grid 8 respectively, so as to lead the overcurrent or overvoltage to the ground through the grounded communication grounding grid 8 .

在本发明实施例提供的电力杆塔共享系统中,杆塔接地网2和通信接地网8之间并未设置接地扁钢,而是采用电绝缘层9将杆塔接地网2和通信接地网8电隔绝。由此,杆塔接地网2接收到雷击产生的较强雷击电流与通信接地网8接收到弱电设备11产生的较弱电流分离,即强电系统接地和弱电系统接地之间实现电气隔离。进一步,在确保杆塔接地网2和通信接地网8之间的电气隔离强度的前提下,为减少电绝缘层9的使用量,电绝缘层9呈圆弧形,即杆塔本体1和基站机房6的外围设置圆弧形的电绝缘层9。在本发明实施例提供的电力杆塔共享系统中,电绝缘层9包括酚醛树脂电绝缘层、环氧树脂电绝缘层、有机硅树脂电绝缘层和/或氟树脂电绝缘层,电绝缘层9的电绝缘效果根据所选材料决定。In the power tower sharing system provided by the embodiment of the present invention, no grounding flat steel is set between the tower grounding grid 2 and the communication grounding grid 8, but an electrical insulating layer 9 is used to electrically isolate the tower grounding grid 2 and the communication grounding grid 8. . Therefore, the strong lightning current generated by the lightning strike received by the tower grounding grid 2 is separated from the weak current generated by the communication grounding grid 8 received by the weak current equipment 11, that is, electrical isolation is achieved between the strong current system grounding and the weak current system grounding. Further, under the premise of ensuring the electrical isolation strength between the tower grounding grid 2 and the communication grounding grid 8, in order to reduce the usage of the electrical insulating layer 9, the electrical insulating layer 9 is in a circular arc shape, that is, the tower body 1 and the base station computer room 6. An arc-shaped electrical insulating layer 9 is arranged on the periphery of the . In the power tower sharing system provided in the embodiment of the present invention, the electrical insulating layer 9 includes a phenolic resin electrical insulating layer, an epoxy resin electrical insulating layer, a silicone resin electrical insulating layer and/or a fluororesin electrical insulating layer, and the electrical insulating layer 9 The electrical insulating effect depends on the selected material.

在本发明实施例提供的电力杆塔共享系统中,由于杆塔本体1上的避雷线3和基站机房6顶部的接闪器7均连接到杆塔接地网2,因此,当杆塔本体1和基站机房6受到雷击时,避雷线3和接闪器7接收到雷击产生的雷击电流,并将雷击电流传输至杆塔接地网2,进而通过杆塔接地网2的接地设置将雷击电流传输至大地。又由于避雷线3和接闪器7均未连接至通信接地网8,而基站机房6内的弱电设备11均连接至通信接地网8,因而接闪器7接收到的雷击电流不会传输至通信接地网8。即通过避雷线3和接闪器7均连接到杆塔接地网2,基站机房6内的弱电设备11均连接至通信接地网8,实现将雷击产生的雷击电流和弱电设备11产生的弱电流分别引入不同的接地网,进而实现强电系统接地和弱电系统接地之间的电气隔离。另外,由于杆塔接地网和通信接地网之间设有电绝缘层,因而,杆塔接地网和通信接地网之间进一步电气隔离,杆塔接地网接收到的雷击电流不会传输至基站机房,进而不会传输至基站机房内部的弱电设备,以达到保护弱电设备的目的。本发明实施例提供的电力杆塔共享系统结构简单,具有较高的电流传导效率以及较强的实施性。In the power tower sharing system provided by the embodiment of the present invention, since the lightning protection wire 3 on the tower body 1 and the lightning receptor 7 at the top of the base station room 6 are both connected to the tower grounding grid 2, when the tower body 1 and the base station room 6 When struck by lightning, the lightning protection wire 3 and the lightning receptor 7 receive the lightning current generated by the lightning strike, and transmit the lightning current to the tower grounding grid 2, and then transmit the lightning current to the ground through the grounding setting of the tower grounding grid 2. Also, since neither the lightning protection wire 3 nor the lightning receptor 7 is connected to the communication grounding grid 8, and the weak current equipment 11 in the base station room 6 is connected to the communication grounding grid 8, the lightning current received by the lightning receptor 7 will not be transmitted to the communication grounding grid 8. Communication grounding grid 8. That is, through the lightning protection line 3 and the lightning receptor 7 are connected to the tower grounding grid 2, and the weak current equipment 11 in the base station room 6 is connected to the communication grounding grid 8, so that the lightning current generated by the lightning strike and the weak current generated by the weak current equipment 11 are separated. Introduce different grounding grids to achieve electrical isolation between the strong current system grounding and the weak current system grounding. In addition, since there is an electrical insulating layer between the tower grounding grid and the communication grounding grid, the tower grounding grid and the communication grounding grid are further electrically isolated, and the lightning current received by the tower grounding grid will not be transmitted to the base station computer room, and thus will not be transmitted to the base station computer room.
