If there are trees planted around the house, do you still need to install lightning rods?

The village does not need to. If you are a detached family, you need it.

Lightning rod is a commonly used lightning protection method in daily high-rise buildings, and its construction method is relatively simple, and the lightning protection effect is relatively good. However, the lightning rod installed on the roof does not ensure the foolproof of lightning, and there is still a small possibility that lightning will bypass the lightning rod and directly split the people in the house and the people next to the house, so to completely avoid lightning, it is still necessary to do some lightning protection precautions in thunderstorms.

Lightning rods are very common in high-rise buildings, and through a metal conductive rod standing on the top of the house, a special channel is used to directly connect with the earth, that is, the top of the lightning rod and the earth directly form a low-resistance conduction state. At the same time, the tip of the lightning rod is often made into a sharp shape, the purpose is to attract lightning more and constitute a tip discharge. Through the low resistance and tip attraction of the lightning rod, the lightning is more inclined to hit the lightning rod rather than to hit the building or other objects, so as to achieve the lightning protection effect of people and objects.

Although the unique composition of the lightning rod makes it easier for lightning to hit the lightning rod, there is still the possibility that lightning will bypass the lightning rod and hit buildings and human bodies. If the person or object standing on the roof or near the window of a building has an electric charge, and it is exactly the opposite of the property of the charge in the clouds, then a higher potential difference will be formed between the two, and the potential difference between the two will even exceed the potential difference between the lightning rod and the clouds, then the object or the human body will be more likely to be split than the lightning rod.

If we think that the theoretical knowledge is more profound, then we only need to remember the knowledge of lightning protection life in thunderstorms and thunderstorms, that is, try to minimize the number of electrical equipment in thunderstorms, or the human body is close to electrical equipment, avoid standing in high places and windows in thunderstorms, avoid using mobile phones in thunderstorms, avoid carrying static electricity on your body, avoid standing in open places, and avoid clinging to houses or tall trees. By doing this, you can greatly reduce the chance of lightning slashing, rather than relying solely on lightning rods.

The lightning rod on the roof can prevent lightning strikes, so it must be installed in the building. The function of the lightning rod is to prevent the electrical wiring of the house from being struck by lightning.

It is not possible to achieve complete lightning protection, it can only be said that the probability of lightning strike is relatively small, and it can be installed.

Lightning rods cannot be 100% lightning protection, but lightning rods will generally not be struck by lightning after installation, unless the lightning is very dense, so there is no guarantee that it will not be struck by lightning.

Not necessarily. Because most lightning strikes can be avoided by installing lightning rods on the roof, lightning may not be completely avoided.

1. It is not necessary to install lightning rods in all buildings, if the floor is not high, there is no need to install lightning rods, in this case, if lightning rods are installed, it will be easier to attract lightning. 2. For rural self-built houses, whether to install lightning rods depends on the height of the house and the decoration on the roof. If the floor is high, and there are some decorative things on the top of the house, such as iron balls, steel balls and other decorative items, it is safer to install lightning rods.

3. It is not necessary to stipulate how many meters there is to install a lightning rod, but to see whether the building is within the protection radius of the lightning belt. For example, if a house has 5 floors, then next to it there is a 6-story building with a lightning rod, which is located within the protection radius of the lightning rod and does not need to be installed. If the house is only three floors, but it is at the highest point in the local area and there is no lightning rod nearby, then it is safer to install a lightning rod.

Hello, after inquiry, it is necessary to install lightning rods in rural self-built houses!

The lightning rod installed in the house mainly plays two roles, one is direct lightning protection, and the other is induction lightning protection. First of all, let's look at what is direct lightning protection, direct lightning protection is mainly to prevent lightning from directly hitting houses or buildings. For example, if the height of the house you live in has exceeded the lightning cable on the high-voltage line, then you must install a lightning rod, especially on the upper floors.

The second is induction mine protection. Induction lightning protection is mainly to protect the common electrical appliances and weak current equipment at home, and now many low-rise families have installed leakage protection, which also plays a protective role. Here is a reminder to the owners of the low-rise floor, regardless of whether there is a lightning arrester installed at home, grounding is a must.

Is the lightning rod installed with the harm of lightning strikes?

Hello, not at all.

should be installed.

The building adopts lightning rod lightning protection, but the external lightning protection, mainly direct lightning protection. It can only reduce the risk of direct lightning hazards in buildings, and there is no way to introduce lightning overvoltages from indoor power supply lines, ** lines, network cables, etc., and cannot protect household appliances and indoor power distribution facilities in buildings. Therefore, buildings must adopt all-round lightning protection technology, that is, comprehensive lightning protection, to ensure safety.

In addition, lightning protection facilities should be regularly inspected and repaired in a timely manner. If the lightning rod (belt) is unqualified or the down wire is rusted and the grounding resistance exceeds the national standard, the lightning rod is not only difficult to protect the building, but will lead lightning into the building, so the lightning protection device should be professionally accepted and regularly tested, and the problem will be rectified in time. So of course it is necessary to install a lightning rod, and there is no harm in it.

Generally, it is not required, and it is generally required to do lightning protection only for buildings above 20 meters. If you build a house where there is a plain area with many thunders or the top of a mountain, you can also install a lightning rod or lightning belt on the roof.

The effect of the lightning rod is similar to that of the lightning rod, but it can be understood as the second layer of protection, when the lightning ignores the lightning rod, it will also be easy to hit the lightning belt, the latter can also play the same effect, the current into the ground network to discharge, reduce the lightning to people and buildings.

So, is it necessary to install lightning rods in high-rise buildings? The answer is: "Yes!" ”

In fact, thunder and lightning also have a principle of proximity, often like to split high, easy to conduct buildings, and then split the middle and low floors (four or five floors) and then split those big trees, and finally split a single layer of this square, and finally split people. However, no one dares to use their lives to win the luck of being struck by lightning, just like the classic flag in the TV series, opening and closing your mouth is to be struck by lightning.

In addition to personal safety, lightning to the building itself is also a certain danger, the simplest handstand is easy to cause damage to the internal electrical equipment, short circuit, resulting in a fire situation, now the building is moving towards intelligence, often the internal circuit is numerous, once the lightning strikes cause damage to the internal circuit, the maintenance cost is also quite amazing, so the design of lightning rod and lightning protection system, must be a compulsory course for all high-rise buildings.

According to the requirements of the building code, lightning protection and grounding works must be done.

1. Permanent buildings need lightning protection and grounding, regardless of high and low floors;

2. The lightning rod is only a part of the lightning protection and grounding project, the project is a complete system, there is grounding underground, transmitted through the steel bars in the main body, the roof is a mesh lightning protection structure, and the lightning rod is set at the top of the wall.

Lightning rods are recommended to be installed with caution.

1.Installation is recommended for the Doré area.

2.Don't install it indiscriminately, otherwise not only will it not be lightning protection, but it will attract lightning (metal devices at the height of the roof) 3The height of the lightning rod is at least higher than the height of the lightning arc that can contact other sharp corners of the building.

4.The lightning rod and its accessories need to be derusted and galvanized.

5.The lightning protection device needs to be connected to the main body of the building.

6.The lightning protection device needs to be grounded, and the grounded steel plate is buried at least one meter deep.

7.If there are no metal sharp corners on the roof, it may not be able to attract lightning to damage the main body of the building, so as long as the electrical appliances in the building are protected, and the market can buy a lightning arrester and install it in the distribution box.

Installing a lightning rod is an effective way to avoid lightning strikes. The tip discharge 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.

Houses need to be installed with lightning rods, and when the houses are delivered, they must also be tested for lightning protection, and they can only be delivered if they are qualified, because the houses are relatively high. When there is thunder and lightning in the air, it may just come down. It's easy to be dangerous.

On the second floor of the house built by Lu Zhili in a rural area, there is no need to install a lightning rod in the house, because there are no big trees or power poles in front and behind the house, so there is no need to push the lightning rod.

The second floor of the automobile house built in a rural area does not need to install a lightning rod, because there are no big trees or telephone poles in front and back of the house, so there is no need to press the lightning rod.

The two-story house of the self-built house in Nongyouzhou Village does not need to be sheltered to install a lightning rod, because there are no big trees or telephone poles in the front and back of the house, so there is no need to press the lightning rod.

There is no need to install lightning rods on the second floor of rural self-built houses, because there are no big trees or telephone poles in front of and behind the houses, so there is no need to press the lightning rods.

There are no tall trees or telephone poles in front of and behind ordinary houses, and two-story rural houses do not need to be installed with lightning rods.

Village houses built on the second floor do not need to be fitted with lightning rods, as there are usually no trees or telephone poles on the left and right of the estates, so there is no need to press the lightning rods.
