There are a lot of thunderstorms in the summer, so if the thunder hits a building somewhere, what wi

In all buildings there is a lightning protection system, it is composed of a lightning device and a grounding ring network, the grounding ring network is done when doing the foundation, with a flat iron, it is connected with the lightning protection wire buried in the building, up to the roof and connected to the lightning device. The lightning device is composed of a lightning rod and a lightning protection net, I don't know if you have noticed, many towering buildings have a tip part, usually that is the lightning rod device, the lightning protection net is along the parapet wall to form a closed ring network, all kinds of lightning protection devices are effectively connected and ensure that the connection resistance value meets the design requirements. Therefore, if lightning strikes a building, the lightning will quickly transfer electrical energy to the earth through the lightning protection system, so that the building will not be damaged by lightning.

The moment the lightning strikes, there will often be a power outage in the building, which is normal, because the lightning will cause the equipment to instantly produce a large amount of electrostatic charge accumulation, which will cause harm to the equipment, so it is recommended that we generally do not go to the computer and watch TV during thunderstorms.

If the lightning hits the ammunition depot or oil depot, it may **, and the building will collapse.

The moment lightning strikes a building, there is a risk that high voltage will be generated in the building's electrical circuits, causing tripping.

The lightning rod uses the principle of tip discharge, so that the electrical charge accumulated in the building after a lightning strike is lost as quickly as possible, and the wires are connected to the ground for the same purpose.

Don't worry about lightning strikes, as long as it doesn't hit people directly, the current house can resist it

How could it collapse? There will be no power outage, I used to see a lightning bolt hit the railing on the roof of our school building (the railing is connected to a lightning rod), and it was a little spark, and everything else was fine.

Both of the above are right. If there is no lightning rod, the wooden house will ** (the Taihe Hall of the Forbidden City was burned down by lightning).

In addition, "thunder" is sound, "electricity" is flashing, and electric current is drawn from the lightning net. (For a detailed explanation of thunder and lightning, see "100,000 Whys.")

Mistake. The high voltage of a lightning strike does not destroy a building, it is the thermal and mechanical injuries of a lightning strike that destroy a building.

Lightning strikes, when lightning strikes, electric current passes through people, land, animals, trees, buildings, etc., causing damage or damage. The discharge between the clouds is harmful to the aircraft and has little impact on the buildings, people and animals on the ground, but the discharge of the clouds to the earth is very harmful to the buildings, electronic and electrical equipment, and people and animals. Once it causes harm to all things, it can be called being struck by lightning.

Formation. A part of the charged cloud and another part of the charge of the cloud, or the rapid discharge of the charged cloud to the earth. This rapid discharge process produces intense lightning accompanied by a loud sound. This is what we see with lightning and thunder.

Of course, the discharge between the clouds is mainly harmful to the aircraft, and does not have a great impact on the buildings on the ground, people, and animals, and the discharge of the clouds to the earth is very harmful to the buildings, electronic and electrical equipment, and people and animals.

This is a relatively unlikely, but no one can say that it is not at all.

Because we all know that lightning protection measures are better in cities, and they are not as direct as under big trees, so there will be no problems in general.

But there is one for everything, but there are some strange news, that is, for example, there are very few news about being struck by lightning in the nest, so once it appears, it will be more eye-catching, because the probability is too low, and it will be on the news if it happens again, so it means that it is still possible to exist, but the probability is particularly low.

The best thing is, of course, not to go out, and staying at home is relatively safest. If you're outdoors, you should pay more attention.

First, be outdoorsKeep an eye out for shelter spotsand try to hide in a safe building or car.

Second, when a rainstorm comesDon't stay under a big tree, don't touch a big tree with your handsDamp tree trunks have become lightning guiding devices, avoid power poles, street lights, billboards, etc., be carefulDo not take shelter from the rain under the high voltage line, avoid roads with heavy water accumulation, and do not move forward if you see a power line falling into the water.

Thirdly, as much as possibleDo not stay near water or in depressionsNever stand on the top of a building or on a higher place.

Fourth, if you can't find a suitable place to hide in timeDon't stand, squat and try to reduce your body heightIt is also necessary to reduce contact with the ground and keep your feet together, because when your feet are separated, it may become a current conduction that can lead to lightning strikes.

Fifth, if you need to stay away from open places or other dangerous places, you should bend forward, bend your body forward to maintain a bent posture, keep your legs bent in a half-squat, keep your feet as close as possible when moving forward to prevent stride voltage, and bend and stretch your head as low as possible.

Sixth, do not stay in the rain with metal objects, and do not turn on your mobile phone or wireless Internet access, which may cause lightning strikes.

Although everyone understands the above, don't think that only children need to learn, some adults think that they are almost dying, because they don't care about the events of thunder and lightning weather abound, the human body is difficult to withstand such a strong current, the probability of being struck by lightning is, many people feel that this probability of things will not happen to them, they are not so much back, but if they are really split, the consequences will not be imaginable, do not have a fluke mentality. Also, during a thunderstorm, you should temporarily turn off the electrical appliances in use and unplug them to avoid electrical fires caused by lightning strikes, and do not use solar water heaters, which are mostly placed on the roof of the house, and can cause fire or electric shock accidents if struck by lightning.

Now the high-rise buildings are installed with lightning rod lightning protectors are not afraid of being struck by lightning, people living in high-rise buildings should pay attention to the doors and windows when it rains heavily to prevent ball lightning from entering the house, and at the same time the lightning weather will not hit ** will be safer.

Install lightning rods on high-rise buildings, buildings that are too high can easily be struck by lightning, and installing lightning rods can avoid losses.

Generally, high-rise buildings will be installed with lightning rods, so that they can prevent being struck by lightning, and people try not to watch TV and computers during heavy rains.

1.This is because the charge has a tip accumulation effect: the charge of the charged body is not evenly distributed on the surface of the object, but "spontaneously" moves at the tip position, which makes tall buildings or trees prone to lightning strikes.

2.Because tall trees and houses are "tip" to the entire earthly curved surface;
