Description

Lei Dunhuan shielding type comprehensive lightning protection device for mobile communication tower lightning receptor

Technical Field

The utility model relates to a comprehensive lightning protection device of a lightning ring shielding type mobile communication tower lightning receiver, which can shield the tower top and the side surface of a tower body of a mobile communication tower, prevent lightning from directly striking or laterally striking mobile communication equipment, greatly reduce the probability of lightning stroke, collect lightning stroke traces, and check and evidence that the lightning stroke is not clear, and is suitable for replacing the needle point type lightning receiver of various existing mobile communication towers, broadcast television towers and the like.

Background

The existing mobile communication tower usually adopts a needle point type lightning arrester for lightning protection, and the main defects of the lightning protection mode are as follows:

1. the tip type lightning arrester installed at the top of the mobile communication tower is utilized to draw lightning for receiving, and lightning can be prevented from directly striking mobile communication equipment on the mobile communication tower, but the mobile communication tower is changed into a lightning arrester, so that the probability of lightning strike is greatly improved, and the lightning protection range of the mobile communication equipment is greatly enlarged.

2. The needle point type lightning receptor arranged at the top of the mobile communication tower has no protection effect on lightning strike, and lightning protection loopholes exist.

3. When the pinpoint receives lightning, lightning electromagnetic pulse can produce dangerous influence on antenna feeder of the mobile communication tower, mobile communication base station equipment and the like, and corresponding protective measures mainly include increasing the height of the pinpoint type lightning receiver, pulling the distance between the pinpoint type lightning point and the mobile communication equipment, wherein the antenna feeder adopts a shielding cable, and the mobile communication base station equipment adopts a surge protector, equipotential connection, good grounding and the like.

4. When the needle point receives lightning and the lightning current flows into the ground through the mobile communication tower and the grounding device thereof, firstly, lightning electromagnetic induction overvoltage is generated on the antenna feeder of the mobile communication tower, weak current equipment insulated to the ground in the mobile communication base station is endangered by lightning invasion waves, and the corresponding protective measures are that a shielding cable is adopted to prevent the lightning electromagnetic induction overvoltage from being generated on the antenna feeder, inhibit the lightning invasion wave gradient on the antenna feeder, and the lightning invasion wave on the antenna feeder is leaked into the ground through the grounding device by using the action characteristic of a surge protector; secondly, in the case of an independent grounding device, lightning ground potential overvoltage generated when lightning flows into the ground through the mobile communication tower grounding device will impact weak current equipment insulated against the ground in the mobile communication base station, at the moment, the surge protector acts to guide the lightning ground potential overvoltage into the weak current equipment, and the weak current equipment insulated against the ground in the mobile communication base station including the surge protector is directly destroyed, while the corresponding existing protection measure is to reduce the grounding resistance of the grounding device to be close to zero so as to reduce the lightning ground potential overvoltage to be close to zero, which is a very difficult or impossible protection measure; thirdly, in the case of parallel connection with other grounding devices, lightning ground potential overvoltage generated when lightning current flows into the ground through the mobile communication tower grounding device and the other grounding devices connected in parallel will strike against weak current equipment insulated against the ground in the mobile communication base station and various equipment insulated against the ground on the other grounding devices connected in parallel, and the equipment damage in a larger range is likely to be caused; fourth, the lightning ground potential overvoltage will have dangerous effects on pedestrians, livestock, other facilities and the like near the mobile communication tower and the grounding device thereof in two forms of lightning contact overvoltage and lightning stride overvoltage, and the corresponding protection measures are to reduce the grounding resistance of the grounding device (namely, reduce the lightning ground potential overvoltage), deeply embed the grounding device in a voltage-sharing manner, and prescribe the safe distance between the pedestrians, livestock, other facilities and the like and the mobile communication tower and the grounding device thereof.

5. The lightning trace is difficult to observe after the lightning is received by the tip, and great inconvenience is brought to the searching and evidence obtaining of the lightning point and the analysis of the lightning cause. With the continuous development of mobile communication networks, mobile communication towers are spread over urban and rural areas, some mobile communication towers are built on open areas or mountain tops, some mobile communication towers are built on urban areas, public sides or building roofs, and the mobile communication towers are always the highest lightning-induced lightning points in the areas, if lightning accidents occur in the areas of the mobile communication towers or the electronic equipment damages faults occur in the houses of the buildings of the mobile communication towers or the nearby buildings of the mobile communication towers which are connected with the mobile communication towers in parallel, the lightning points cannot be found, and the situation that the lightning is not proved can not be found, so that no matter whether the tip-type lightning receptors at the tops of the mobile communication towers receive lightning, mobile communication tower operators are likely to be responsible for lightning-induced lightning, people in the areas of the mobile communication towers can generate unsafe feelings, and the lightning-induced lightning disputes occur between people and the mobile communication tower operators can be caused, and the development of mobile communication industry can be seriously affected.
