Why can't I play computer when it thunders? What is the reason (detailed)

Thunder is the phenomenon that clouds with positive and negative charges discharge when they are close to a certain distance, and thunder is the sound produced by discharge; The impact of lightning on the computer is that the electric shock released in the transmission network produces high voltage, and the computer will restart if the voltage is not too high, which has little impact on the computer; If high voltage is generated, it will cause great damage to all electrical appliances (including computers); When it thunders, lightning generates high-voltage electricity, which will be transmitted to the user's electrical appliances by hanging wires upside down. At this time, if the electrical appliance is in use, the high voltage generated by lightning will break through the electrical appliance. There are two kinds of lightning that cause damage: 1 ordinary lightning, and lightning on the second floor. Regardless of it, it only shows its power in the sky. There are two kinds of lightning that are harmful to computers. 1 The possibility of direct combustion with high current through the conductor is very small and can be ignored. One-millionth of 2 thunderbolts generate powerful electromagnetic waves and damage the computer hard disk. This situation is rare, but it cannot be ignored. If you love computers very much, you'd better turn off the TV: when watching TV during thunder, the picture is very unstable and there is a lot of interference, and you are always a little afraid that the machine will destroy people. Is this possible? In fact, as long as you don't connect the outdoor antenna and use the TV indoors, there is generally no need to panic, because although the lightning is fierce, before entering the room, the thunderstorm cloud has already discharged with the earth. In the process of short-time discharge, most of its huge energy is converted into heat, light and other energy, so it will not cause harm. Usually, when it thunders, I watch TV in my room. Most of the interference on the screen and in the sound is the radiation energy of lightning, not the energy of induction or discharge. This radiant energy generally won't damage the TV set. However, it must be emphasized that it is very dangerous to use outdoor antennas or watch TV when it thunders. If you watch it, you must take lightning protection measures. Electric light: when it thunders, the voltage becomes very large instantly, which will cause the electric light to go out and cause a fire. However, there is usually no need to turn off the lights. Because the voltage is getting bigger, the work of the substation is suspended, that is to say, there is a power outage, so the lights at home will automatically turn off even if they are not turned off, which is very safe. Computer: Strong lightning voltage will cause semiconductor integrated circuits to be instantly broken down and lose their original polarity. Therefore, the integrated circuit will be damaged. A computer is composed of a large number of integrated circuits. When the integrated circuit is broken, the computer is broken. In addition, the voltage of lightning is very high. Instantaneous high-voltage discharge will decompose and burn nitrogen in the air, release a lot of heat and burn the computer. Moreover, the type of lightning belongs to static electricity, and everyone who knows the circuit knows that static electricity is the first killer of integrated circuits. Lightning has the opportunity to generate instantaneous high voltage on the wire. At this time, high voltage may break through electrical components, which may lead to explosion in severe cases and burn the safety tube in minor cases. Therefore, in areas with severe thunder, sometimes even the lights have to be turned off, because it may suddenly explode and hurt people nearby. Of course, if the thunderstorm cloud is high, it has no effect. Generally, thunder sounds scary, and the clouds are very low, so it must be turned off at this time.

Can I play computer when it rains and thunders?

To find out whether electrical appliances can be used in thunderstorm weather, we must first understand the following lightning protection theories:

1. According to IEC specifications, lightning rod belongs to external lightning protection device, which is used to protect the building body from lightning damage. However, if lightning strikes the distant power line or data line, the lightning current will enter the room along the metal line. At this time, the external lightning protection device cannot prevent lightning current from entering the room along the line.

2. In order to prevent lightning current from entering along the line, internal lightning protection measures should be taken, such as shielding, grounding, equipotential and lightning arrester (SPD). There are no lightning protection measures in general houses. In other words, it is possible to be struck by lightning when using a computer in a thunderstorm.

3. If you really want to play, you can refer to the following lightning theory: When lightning strikes, the electronic equipment near the lightning strike point 1 km may be damaged by electromagnetic induction. In addition, the power line is generally grounded every two or three poles, and the signal line is generally buried, which is less likely to be affected by lightning and electromagnetic induction. Calculate the time interval between the appearance of lightning and the hearing of thunder. If it is greater than 10 second, it means that the lightning strike occurred 3 kilometers away (the speed of sound is 340m/s), and it is generally safe at this time.

4. To ensure safety, the power cord and data cord of all electrical appliances should be unplugged. Note: it was unplugged, not turned off! Electrical switch is low voltage, and lightning is high voltage of hundreds of thousands of volts, which can directly break through the switch of electrical appliances and enter the interior of electrical appliances.

5. I haven't seen fiber TV. Is the fiber-optic TV directly connected to the TV or does the trunk fiber go to the community and become an ordinary TV line? Pure optical fiber is not conductive, but in order to strengthen the strength of optical fiber, a reinforcing rib (steel wire) should be added in the middle of the optical fiber cable, so the optical fiber line may also be struck by lightning. In engineering, it is generally not necessary to install lightning arrester at the optical fiber port of the computer room with optical fiber, but the reinforcing rib (steel wire) of the optical fiber should be grounded. If you don't know, you'd better unplug it, safety first.

Why can't I play computer when it rains?

When it rains, you can play computer. Generally speaking, people often play computer at home when it is not suitable to exercise outside. If it thunders, you need to pay attention. Lightning may cause electrical appliances to burn out. If there is lightning nearby, turn off the computer first and wait until the lightning has passed before playing. If it thunders, collect clothes first, then rest at home, turn on the computer and have a good time as soon as possible, and change to a desktop with pleasant scenery in Hitachi by the way. Sunshine always comes after a storm.

Can I play computer when it thunders? 20 points

It depends on thunder, if it is a storm, lightning and thunder.

I advise you to turn off the computer! Unplug the tripod too, because the computer will be struck by lightning.

If there is not much rain and thunder, you can play, and it is too late to turn off the computer when it thunders.

Can I play computer when it thunders?

Voltage fluctuation in summer and daily lightning have great influence on computers. Because at this time, the instantaneous surge and peak voltage that may occur at any time will directly test your power supply and host. If your power supply has protection function, the loss will be small, otherwise you will be depressed. Maybe you will say: What's the matter? I never had any problems. But once something goes wrong, it will be too late for you to regret it, because natural damage (damage caused by force majeure) is not covered by the warranty. Just as I always advise you to buy high-quality power supply, a high-quality socket with surge protection function is also essential.

Matters needing attention in using computer

Turn on and off the machine correctly, first turn on the monitor power supply and then turn on the host power supply, and vice versa when turning off the machine; Never turn off the phone by force.

Please place the computer carefully, away from high temperature, humidity and dust, and avoid direct sunlight.

Pay attention to lightning protection in summer. Don't use the computer when it thunders and rains. Better unplug the power cord.

Avoid the influence of magnetic field on the computer. Don't put it too close to TV, speakers, amplifiers and telephones, at least two meters apart.

The computer is equipped with a special electrostatic wiring board to prevent crosstalk.

Avoid humid environment. In the rainy season, turn on the computer that has not been used for a long time and execute it for a period of time; When the weather is dry, appropriately increase the indoor air humidity.

When it thunders, the computer automatically shuts down, so you can't play computer after that?

Generally, hard disks are easy to break down. So is the motherboard. . It is recommended to unplug the plug and network cable after Thunder is automatically turned off. .

Why can't I play with my mobile phone when it thunders?

I wonder if you can understand this explanation. When you make a phone call (in fact, as long as there is a battery in the phone, whether it is turned on or not), the phone will emit and receive electromagnetic waves into the air (just like you put a kite with a wire tied). When it thunders, if the lightning just passes through the area near you, it will give you a close contact along the channel you set up! I don't have to tell you the ending!

So don't use your mobile phone in a thunderstorm, try not to play! If lightning is approaching, please remove the battery if possible! Or stay away from it. . . .

Can't you play with your mobile phone computer on a thunderous day? How can I not be afraid of thunder and let me continue to play?

Try to avoid fiddling with electrical appliances during a thunderstorm. Especially when you make a fixed telephone or mobile phone, you are killed if you are unlucky. The only solution is the computer grounding wire. Generally, there are ground wires on the surface of buildings in residential areas, and every family has a ground wire interface.

Please accept it, thank you!

Rain has little effect on the computer.

But thunder is different. '

Lightning will destroy any of your appliances.

Mainly depends on the size of the thunder. Don't think that turning off the power will be all right. If possible, you'd better unplug the network cable, or you may hit your network card.

When it thunders, lightning will be transmitted to the terminal through some communication lines or power lines. If the voltage is too high, the voltage regulator will not work. Everyone knows that you can't turn on the computer when it thunders to prevent lightning strikes. In severe cases, it will burn network cards, especially ADSL cats, and even computer hosts and monitors. So you can't play computer when it thunders, and you have to unplug the network cable.

You can close the open window when it thunders, but you'd better close the window.
