What is the height of the lightning rod in Zhongtian Plaza? Lightning rod position setting as well a

No one has ever measured the height of the lightning rod in Zhongtian Plaza, you had better ask the construction party, even the staff of Zhongtian Plaza do not understand this situation, only special professionals understand this situation lightning rod.

The height of lightning rods is generally between 36m and 360

Zhongtian Plaza office building has a total of 59 floors, with a height of meters and an altitude of 910 meters, if the height of the office building alone and the lightning rod can reach more than 250 meters.

There is a lightning rod on the barrier of Zhongtian Square, and the height of the lightning rod is still very high, which can compare the surrounding thunder.

Its height should be. Rice. Then the length of his needle should be 40 meters, and if you want to increase it, you can increase it to 50 meters.

The height of the lightning rod in Zhongtian Plaza is average, and the length of the lightning rod is two meters.

Left and right, there will also be multiple lightning rods around the top floor, each with a distance between two meters and one meter 5.

If you have a high altitude, you need to find out on your own, and you can't judge it according to your local situation, so you have to judge it yourself.

The building has a total of 59 floors (56 above ground and 3 underground) with a floor height of meters.

If you need to protect this 4,000 square meter rectangular area, the height of the lightning rods at the four corners should be at least 40 meters, and if the height is increased to 50 meters, you can reduce the lightning protection by one.

Zhongtian Square is in the lightning rod, the height is generally about 15 meters, because it is twenty or thirty meters higher than the house, generally, if he gets to the house, it is more than five meters higher than the house to be called a lightning rod. If it is longer than Thor, it is definitely 15 meters high.

The height of the lightning rod in Zhongtian Square is generally there. Five meters to more than ten meters are very high lightning rods.

Square lightning rod, height lightning rod, must be high, not high is not easy to make, lightning rod can be high or high.

What is the height of the lightning rod in Zhongtian Plaza? The height of the lightning rod in Zhongtian Plaza is average, the length of the lightning rod is about two meters, and there will be a number of lightning rods around the roof, and the distance between each lightning rod is two meters to 1.5 meters.

If you want to check this kind of high-tech thing, your mother must go to the database to check it accurately, and most people are not clear about these details.

The height of the lightning rod in Zhongtian Square is higher than that of Zhongtian Square.

I think the height of the lightning rod in Zhongtian Square should be about twenty or thirty meters higher than all the buildings.

Zhongtian Square lightning rod, generally he is more than five meters taller than the house, or it will have no effect if you don't tell it.

The height of the lightning rod in Zhongtian Square is average, and the height is generally about two meters, and its spacing is also between one meter and five to two meters. There are a lot of lightning rods.

I think the lightning rod is at least 30 meters long.

The protection zone of the lightning rod is the umbrella zone of 45 60 ° below the lightning rod. The higher the lightning rod is erected, the larger the scope of the protected area. When installing a lightning rod, it must be noted that the distance between it and the protected object should be greater than 5m, because the lightning rod and the down conductor can penetrate 2 3m of air by lightning induction.

The grounding body is a metal object buried in the ground, usually made of steel pipes, angle steel, steel bars, etc., and the length should be 1 2m. The burial depth is not less than 2m. The lightning rod grounding body cannot be mixed with other grounding bodies, and must be grounded independently.

2 hours ago: The height of the lightning rod in Zhongtian Plaza is average, the length of the lightning rod is about two meters, and there will be multiple lightning rods around the roof, and each lightning rod is between two meters and 1.5 meters apart.

The height of the lightning rod in Zhongfu Square is about 35 meters, which is also this size.

The height of the lightning rod in Zhongtian Square is generally between 50 and 60 meters, because it is higher than the house, so the lightning rod is about 50 to 60.

The lightning rod height of Jomtien Plaza is the highest of all buildings.

The height of the lightning rod in Zhongtian Square, the height of Zhongtian Square is generally about 15 meters, because it is twenty or thirty meters higher than the house. If it is longer than Thor, it must be 15 meters tall, and if it is shorter, one or two meters will do??

If you need to protect this 4000 square meters of rectangular area, the height of the lightning rod at the four corners should be at least 40 meters, if the height is increased to 50 meters, you can reduce a lightning rod, the installation position is at the two corners of a long side and the midpoint of the long side of the opposite side, if the midpoint of the rectangular side width can be installed lightning rod, 40 meters high, then only 2 is enough, if it can be installed, the height needs meters, you can protect the entire range.

(1) There should be a distance of not less than 5m between the independent lightning rod and the protected object to avoid counterattack when lightning strikes the lightning rod. An independent grounding device should be set up for an independent lightning rod, and the distance between the ground and the grounding network should not be less than 3m.

2) 35kV and below high-voltage power distribution device structure and roof should not be installed with lightning rods. The lightning rod installed on the frame should be connected to the grounding grid, and a centralized grounding device should be installed.

3) The station structure of the transformer should not be equipped with lightning rods.

4) The lightning rod and grounding device should be more than 3m away from the road and the exit, otherwise the gravel or asphalt surface should be paved with a thickness of 5 8cm to protect people from the danger of stepping voltage.

5) It is strictly forbidden to install overhead lighting lines, first-class lines, broadcast lines, antennas, etc. on lightning rods or frames.

6) If the lighting is installed on the independent lightning rod or frame, the power cord must use a lead cable or penetrate the steel pipe, and be directly buried in the ground with a length of more than 10m.

The height of the board house is about meters, do you still need a lightning rod?

Reasonable selection of lightning rod protection range calculation method.

The calculation methods of the protection range of the commonly used lightning rod (here only refers to a single needle) mainly include the polyline method and the rolling ball method. The main features of the "polyline method" are intuitive design, simple calculation, and saving, but it is not suitable for buildings with a height greater than 20m; The main feature of the "ball rolling method" is that the protection range of the lightning rod or lightning belt can be calculated when combined with the grid, but the calculation is relatively complex, and the cost calculated according to this method is large.

Among these two calculation methods, the "polyline method" is a relatively mature method, and it is also known as the "procedure method" in the power system, that is, the protection range of a single lightning rod is a polyline cone with the lightning rod as the axis.

The protection range of a single lightning rod is specified in the standard DL T620-997 "Overvoltage Protection and Insulation Coordination of AC Electrical Installations"; The "Rolling Ball Method" is one of the methods used by the International Electrotechnical Commission (IEC) to calculate the protection range of flash connectors. China's building lightning protection code GB50057-1994Z also compulsorily uses the "rolling ball method" as a method to calculate the protection range of lightning rods.

The ball rolling method is to roll a sphere with a radius of HR along the part that needs to be protected from lightning strikes, and when the ball only touches the lightning receiver (including the metal objects used as lightning receivers) or only touches the lightning receiver and the ground (including metal objects that are in contact with the earth and can withstand lightning strikes), and does not touch the parts that need to be protected, the part is protected by the lightning receiver.

In recent years, the "rolling ball method" stipulated in the national standard has also begun to be recognized by the industry, but the "rolling ball method" has also encountered some problems in practical application, especially when calculating the protection range of the lightning rod on the roof. In general, these two algorithms have their own characteristics, and generally high-rise buildings use more "rolling ball method".

Starting from the top of the lightning rod, the gas pipeline can be covered within a downward range of 45 degrees.

A preliminary decision should be made on the basis of a map of the distribution of mined areas in the national division of the bai.

Whether or not to set up a lightning rod should be determined according to the terrain conditions, the minefield, the height of the building, the height of the adjacent building, and the distance of the shadow. It should be decided concretely through regulations and calculations. You can consult the relevant manuals as a basis for calculations and references.

How much can a lightning rod protect? Today is a long day of insight.

In fact, you have a misunderstanding, that is, why do you need to install lightning rods, lightning rods protect the location of the building; Why improve the lightning belt and the protective position of the lightning belt? Are you more aware of the contradiction that lightning rods are lightning rods again?

Also, you focused on the lightning rod, but what is the grounding state? How about the connection of the common poles, these are more important for the civil construction, but you are just negligent.

The lightning points of civil buildings are generally in the corners, such as floating eaves, and your lightning protection belt should be connected to those places safely. If there is no building on the roof, such as a solar water heater, you should not set up a lightning rod at all.

To measure the ground resistance, it is the most secure safety system to connect the columns and the underground ring beam reinforcement of the concrete to the ground pole, do a good job of equipotential plates, and connect the electricity and weak electricity into the house.

Don't think that a lightning rod will solve everything. That was a long time ago.

Generally speaking, the higher the lightning rod, the greater the protection range and the better the protection effect, but considering the safety and economy of lightning rod construction, lightning rods are mostly built between 35 meters and 45 meters.

Use a few lightning rods, depending on how much range needs to be protected, if the range of protection is larger, the number of lightning rods needed is more, and the range of lightning rods that need to be protected is smaller, the number of lightning rods needed is different.

You can also consult Morgan Lightning Protection directly. The company's technology and service are relatively good. Reference.

The coverage area of the lightning rod is an angle area of 45° of the height of the lightning rod.

The tower body is metal, and it is itself a lightning receiver (lightning rod).

Answer 1: (1) The height of the lightning rod on the long side of the house = 6 meters + 4 (house height) (2) The height of the lightning rod on the short side of the house = 8 meters + 4 (the height of the house) Answer 2: (1) The height of the lightning rod on the long side of the two houses = 10 meters + 4 (house height) (2) The height of the lightning rod on the short side of the two houses = 12 meters + 4 (the height of the house) (3) The lightning rod between the two houses is calculated according to the second length.

The above calculations are theoretical values, and it is recommended to increase them slightly after considering the tolerances and safety factors.

It is best to use the lightning arrester in the center of the trellis to save the height of the lightning rod. The ratio of half height h to protection radius r = , the material of the grounding wire should preferably be reliably grounded, and you can use the grounding network of the building.

The lightning rod is composed of three parts: a lightning receiver, a grounding lead and a grounding body. The flash receiver is usually made of round steel or steel pipe with a diameter of 15 20mm and a length of 1 2m, which is fixed at the upper end of the pillar and connected with the grounding body through the grounding lead.

It must be strictly ensured that the lightning rod is reliably grounded, otherwise, it is a lightning guide to confirm the grounding resistance. It is best to use a relatively strong metal such as steel bars to connect the lightning rod with the building grounding bar. It's dangerous.

The lightning protection of the lightning rod is a relative term, and its function is to direct lightning to the ground and protect buildings from lightning damage. The above one is very correct, to ensure that the ground resistance is not greater than 10.
