How should the lightning rod be connected 10

Both are fine. 1. Because the staircase reinforcement mesh is interconnected, including the low foundation, it is a huge grounding grid. Of course, the connection points must be welded and anti-corrosion.

2. If it is used alone" = 16 square aluminum core wire (copper core is better) as the lower guide line, 5 * 5 flat iron and angle steel are used as the grounding cage, and all nodes are welded and anti-corrosion.

It can be said that it is safe, and the lightning rod that is needed is selected according to the size of the lightning current prevention.

The building is the seventh floor, if the area is not very large, it is not a cultural relic, it is not an important office building, then it can be designed according to three types of lightning protection. It is enough to use the steel bar in the structural column at the inflection point of the building as the down lead, and the foundation steel bar as the grounding body. The roof can be laid with some round steel as a lightning arrester.

There are more than two down wires, depending on the size of the building itself.

The installation of DK8 BX10 lightning rod must comply with the National Standard of the People's Republic of China (GB50057-94) "Construction.

Physical lightning protection design code", the specific construction must strictly follow the national standard of the People's Republic of China (GB 50169-92) electrical installation engineering grounding device construction and acceptance specifications, thunderstorm days can not be carried out lightning rod installation and testing.

When ordering, please inform you of the technical parameters of the lightning rod (tower) rod you choose, so that the factory can choose a more standardized interconnection adapter installation accessories for you.

The metal cylinder equipped with a lightning rod can be used as the down conductor of the lightning rod when its thickness is not less than 4mm. There should be two symmetrical connections with the grounding body at the bottom of the cylinder.

When the lightning protection facilities of building L adopt multiple down conductors, it is advisable to set up a disconnection card at the place where each down conductor is from the ground, and the disconnection card should be insulated and protected.

The connection between the lightning rod and the down conductor should be welded.

The grounding device of the lightning rod should adopt a bottom-up construction procedure. First, install the centralized grounding device, then install the down conductor, and finally install the lightning rod.

Do not touch the main flash tip or active discharge tip during installation.

The product is designed to have a service life of 20 years.

Stand the lightning rod upright, straighten it and carry out spot welding, during which it is continuously corrected to weld the remaining three ribs. 3. Weld the down conductor to the bottom plate of the lightning rod, remove the coating and paint and oil, and take anti-rust and anti-corrosion measures.

1. First of all, bury the anchor bolt in the ground, and then fix the steel plate base of the lightning rod.

2. Then weld an auxiliary plate up.

3. Then stand the lightning rod upright, fix it with spot welding, and weld the remaining three auxiliary plates.

4. Finally, weld the lead wire under the floor, apply paint and carry out anti-rust treatment.

1. The metal parts used on the lightning rod must be made of galvanized materials, and the surface layer of these galvanized materials should be protected in the process of installing the lightning rod.

2. The tip of the lightning rod is best made of galvanized steel pipe or round steel, the diameter of the tip should be greater than 25mm, and the thickness of the wall of the galvanized steel pipe should be more than 3mm, the tip of the needle must be tin-shabu, and the length of the tip must be more than 70mm.

3. During the installation process, all the solder joint positions are cleared after the coating is removed. In the process of installing the lightning rod, after all the solder joints are cleared and the coating is removed, it is also necessary to take relevant measures such as anti-corrosion and anti-rust, so as to prolong the service life of the lightning rod.

Lightning rods prevent lightning strikes by attracting lightning and controlling it onto the grounding body.

The principle of lightning rod is to use the conductivity of metal, when lightning strikes, the potential of the lightning rod is lower than that of the surrounding buildings, according to the principle that the potential is equal to zero, the air between the lightning rod and the building is ionized, thus forming a channel, so that the lightning strikes are channeled into the ground through this channel, avoiding lightning strikes other objects.

The structure of a lightning rod is generally divided into three parts: the needle, the shaft, and the grounding body. The needle is the uppermost end of the lightning rod, and its shape can be rod-shaped, conical, conical, etc., which is used to direct the lightning current.

The shaft is the middle of the lightning rod, which is generally a metal rod and is bent to connect the needle to the grounding body. The grounding body is the lower end of the lightning rod, which is buried in the ground and is used to direct lightning current to the ground.

Precautions for using lightning rods

1. Before using the lightning rod, it is necessary to ensure that the quality of the lightning rod is qualified, the installation is reasonable, and the grounding is good.

2. The head of the lightning rod should be installed on the top of the building, and should be installed in a conspicuous position to remind people of the existence of the lightning rod and avoid the hazards of lightning strikes on personnel and equipment.

3. The installation height of the lightning rod should also be set in accordance with the relevant specifications and standards to ensure the effectiveness of the lightning rod.

4. When using lightning rods, special personnel should be assigned to regularly inspect and maintain them to ensure the normal operation and effectiveness of lightning rods.

Installing a lightning rod is an effective way to avoid lightning strikes. A metal rod is erected at the highest point of the house, and a copper wire is connected to the lower end of the rod, and a metal plate is attached to the end of the copper wire and buried in a damp place deep underground. The upper end of the rod must be a pointed end or bifurcated into several pointed ends.

With such a device, when there are charged clouds in the sky. The tip of the lightning rod is concentrated with a different charge due to electrostatic induction, and the tip is discharged, which is neutralized with the electric phase in the cloud to avoid the occurrence of intense lightning, which is one aspect of lightning rod can avoid lightning. But this effect is quite slow, and if the accumulation of electricity in the cloud is very fast, or if a cloud with a large charge suddenly flies in, sometimes it is too late to neutralize it in the manner described above, so there is a strong discharge, and the lightning will still occur.

However, because the lightning rod is higher than the surrounding objects, its tip is concentrated with the charge of the electricity in the cloud, if the lightning occurs between the cloud and the ground object, the discharge current mainly flows into the earth through the lightning rod, so it will not hit the house or nearby people, but will only hit the lightning rod. It can be seen that the tip discharge effect of the lightning rod will reduce the possibility of lightning between ground objects and clouds. When it was inevitable, it itself was hit by thunder, and the house and people were safe. Due to the structure and function of the lightning rod, we should pay special attention to maintaining the good conductivity of the lightning rod.

Once there is a bad connection, or it is broken, the section above the fracture becomes an isolated conductive system. When there is an electric charge in the cloud, the upper part of the separated part induces a charge with the same name as the electricity in the cloud, and the lower part induces a charge with the same number as the electricity in the cloud. In this way, not only can it not avoid lightning, but it will also attract lightning disasters.

To prevent accidents, it is best to erect several lightning rods in tall buildings. In addition, each lightning rod can only protect a certain amount of floor area. For larger buildings, several lightning rods are also required.

Answer 1: When making a foundation, install the grounding electrode: during the construction of the structure, use the steel bar (or special section steel) in the structure as the down wire, connect with the grounding electrode, and reserve the connection point with the lightning protection belt; At the same time as the decoration is completed, lay the lightning belt (or lightning rod).

2. The lightning rod specifications must meet the GB standard, and the lightning rod height specifications required for each lightning protection category are different. The lightning belt is generally made of galvanized round steel with a diameter of not less than 8 mm or flat steel with a cross-section of not less than 48 square millimeters, and its size should not be less than the following values.

3. The installation of down conductors should meet the following three requirements:

a. The diameter of the round bar is 12 mm.

b. The down wire is a wire connecting the lightning rod or lightning belt and the grounding device, which should generally be higher than the 0 of the roof.

c. The down conductor is 2 meters above the ground.

4. There should be at least 2 down wires, and the protection radius of a single lightning rod is 1 of the height of the lightning rod.

5. The down conductor should be laid along the outer wall of the building, and the height of the lightning rod can be determined according to the length and width of the house, and 5 meters should be laid along the roof.

The working principle of the lightning rod is essentially to guide the lightning, using its own high-altitude position, when the lightning cumulus moves to the top of the lightning rod, the lightning is led to its own lightning discharge, and it is dispersed through a good grounding network into the earth. This protects the surrounding buildings or equipment from lightning strikes.
