A couple of questions about thunder!! What happens if the house is hacked without any lightning prot

1.It is possible, there will be rain in the general category, and the wet ground will conduct electricity.

There was once a report that an elementary school in the mountains was struck by lightning on a rainy day, and the students were knocked down, ** overestimating the trauma.

2.Lightning has little to do with whether the windows are closed or not.

3.If you're in the house, it shouldn't be a big problem.

4.Lightning does not come in from the air, it is actually a high-voltage electric current, and there is a metal object or water that attracts and conducts electricity.

5.Don't go online! Unplug all electrical appliances in the home during thunderstorming, otherwise you will split the wires and break the electrical appliances. It is very rare for lightning to injure people, and it is very common for electrical appliances to be damaged. My computer network card has been hacked.

Large buildings or important sites are equipped with lightning rods, so it's fine.

Hope it helps you o ( o haha

1. Generally not;

2, Yes; 3. It has nothing to do with mobile phones;

4. The height of the roof is not more than 20 meters, which is generally safer;

5. A "vacuum arrester" should be installed.

In thunderstorms, houses with reinforced concrete structures are safer than houses with brick and concrete structures;

Staying in the car, in the elevator, under the safety net, is relatively safe;

The power supply should be cut off;

Communication facilities such as antennas should be "shorted";

Don't use wired**; Wait a minute.

It depends on the situation, if the lightning strikes the person, then the person will not die. It's not so exaggerated, how can a mine make people program a snail. Generally a good phone is not dangerous.

Unless you do something hurtful, you will generally not be criticized, but it's a good idea to be careful, and try to do as little as possible when you know the danger.

Lightning strikes belong to a kind of conductive situation, generally low buildings will not cause lightning strikes (except for too many conductive objects at home), high floors are generally installed with wall lightning rods, and as long as you pay attention to the situation that lightning should be avoided when thundering, it should not hit the house.

Related Notes:Thunder is a natural phenomenon, and when it rains, some clouds in the sky have positive poles and some negative poles. When two clouds collide, lightning strikes, and at the same time emits a lot of heat, heating and expanding the surrounding air. The air that is heated and expanded in an instant will push the surrounding air, causing a strong **-type vibration.

This is thunder.

When lightning and thunder, wind and rain are combined, if tourists are resting in the hotel, they should immediately turn off the indoor television, cassette recorder, stereo, air conditioner and other electrical appliances to avoid electrical conduction. When thundering, it is safer to be in the room, do not stay under the electric light, and do not rely on the pillars, walls, doors and windows, so as to avoid accidents caused by induction electricity during thunder.

First, the houses in the city are installed with lightning rods; Second, in the countryside, because the house is short and there are many trees around it (trees can be used as lightning rods, so don't go under the trees to take shelter from the rain when thundering); Fourth, even if your house is tall and there are no tall trees around, but the chance of being struck by lightning is very small, but for safety, you can install a steel bar (long meter) at the four corners of the house to ground with wires.

The three of them hid under the eaves, thunderbolts and fires, the middle one was killed, and the two sides were fine.

This place was called Leizhou in ancient times!

Of course it's possible! Install a lightning rod! Remember to connect the ground wire!

If Lei Da is possible. If there is a lightning rod, it is impossible.

The house was struck by lightning, which means that the house was struck by lightning when the thunder struck.

You know that thunder and lightning are generated by electricity, and if the clouds are too low and the house is high, it will inevitably hit the house. The safest way to do this is to install a lightning rod and connect it to the ground, so that the power will be diverted with it. Hope to adopt.

Your house is in a minefield, and the house has something that can conduct electricity, and it is strange that the ground wire is not installed, and the lightning does not split! This is the traditional interpretation.

It is necessary to talk specifically about the structure of the house.

1. Whether there is a lightning rod or not has nothing to do with your problem. According to IEC regulations, lightning rods are external lightning protection devices that are used to protect the building itself from lightning damage. However, it does not prevent lightning currents that enter the chamber along the line.

2. In order to prevent the lightning current entering along the line, it is necessary to take internal lightning protection measures, such as shielding, grounding, equipotential and lightning arrester (SPD). Generally, there are no internal lightning protection measures in residential buildings. In other words, there is a possibility that the computer used in a thunderstorm will be struck by lightning.

3. If you really want to play, the following lightning theory can be referred to: when lightning strikes, electronic equipment within 1 km of the lightning strike point may be damaged by electromagnetic induction. In addition, the power line is generally every 2 to 3 poles for grounding protection, and the signal line is generally buried in, and the probability of being affected by lightning strikes and electromagnetic induction is small.

Calculate the time interval between the occurrence of lightning and the hearing of thunder, if it is more than 10 seconds, it means that the lightning strike occurred 3 km away (the speed of sound is 340 m s), and it is generally safe at this time.

4. If you are really struck by lightning, call 120 first, and then do artificial respiration and cardiopulmonary resuscitation. There is no electricity on the body of a person after being struck by lightning, so it is safe to contact it and will not harm the rescuer.

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.

First, the steel bar on the roof of the building is the lightning protection device, which is equivalent to a lightning rod, or a lightning receiver, or a lightning collector, the purpose is to introduce the current into the ground when the lightning is approaching.

Second, if it is a house built by yourself, it is not on the mountain, and it is not particularly high, and there is almost no possibility that the house will be struck by lightning.

Third, it is safest for people to be in a closed room, it is best not to touch the four walls, unplug all electrical appliances, and turn off mobile phones and other electrical appliances. Don't shower, don't stand ......

Fourth, direct lightning: It is also possible to enter the room through wires, signal lines, water pipes, gas pipes, etc., thus causing harm to people indoors. Both electrostatic induction and electromagnetic pulses have the potential to cause damage!

Buildings without lightning protection will be prepared for damage to electrical facilities in the building if they are struck by direct lightning.

If there is a lightning bridge and there is no grounding, it will increase the probability of lightning connection of the building, and it will be more dangerous if there is no discharge channel for lightning connection, especially for residents on the top floor.

Of course, household appliances in the building can also be damaged by lightning disasters (mainly overvoltages introduced by power or signal lines).

There is lightning protection, nuclear excitation, no grounding, etc., and guess that there is no lightning protection. There are two hazards of not doing lightning protection, one is physical, lightning strikes will damage buildings, generally starting from the edge; The second is electrical nature, when lightning strikes, the induced voltage and induced current will damage the electrical equipment.

Installing a lightning rod can't solve this problem, after all, you can't install the lightning rod very high, so the lightning rod's lightning guidance effect is not obvious. If you can't avoid lightning strikes, if you hit it and reach other parts of your building, if I do this, I will do this: install a lightning rod between my water tank and water heater, and then install a lightning belt on the outer frame of the roof of my house (the function of the lightning belt is that the lightning strikes the house, and the lightning current can be carried away with the lightning protection.

Instead of following the house cement, because there is no lightning belt house was split a corner down the thing I have seen a lot). It is also necessary to make a ground net in the square of the ground (and the mold oak is not simply an angle iron, if a simple angle iron is really struck by lightning, it cannot be released). Connect the lightning rod with the water tank, water heater, and lightning belt, and then lead it to the ground network through the down wire made of copper tape, and then the square down wire is too small.

The area protected by the lightning rod is 45 degrees downwards with the vertex of the pointer as the center of the circle.

Since the water tank is about 3 meters above the roof, it is recommended to press the water tank directly above the water tank to dig the stove plum!

If you have a lightning rod, you are most susceptible to lightning strikes...
