I want to install a satellite dish at home, but I am afraid that there will be danger in case of thu

You can choose an insulated thing to put on the receiver in the middle of the satellite antenna, one to prevent weathering, two to protect against lightning, and three will not affect your reception

Thunder is not dangerous, it is dangerous if you are caught, you have to be fined, seriously agree, thunder is fine, thunder is fine, do not turn on the TV on thunder days (in fact, if you are not particularly unlucky, thunder days are fine).

Don't be alarmist, my family has been watching it for seven or eight years, and no one has come to fine me.

Under normal circumstances, it doesn't matter if there is thunder, and nowadays electronic products are equipped with lightning protection devices, so there is no need to worry about it at all.

Do you live in the city or in the countryside?

The city must be installed on the roof of a building, surrounded by buildings that are taller than your antenna. If it is not necessary to install it in the house in the countryside, it can also be installed in the courtyard.

Thunder is not dangerous, it is dangerous if you are caught, and you will be fined.

1. The formal practice is to keep the antenna within the protection range of the lightning protection device, that is, the LPZ0B area mentioned in the specification. Then take lightning protection electromagnetic pulse measures (shielding, grounding, equipotential, arrester).

2. It is impossible to do this in the family, and the cost is too high. Therefore, when there is thunder, it is enough to unplug the antenna feeder from the receiver and put it in a position that cannot be reached by people, at most the feed on the antenna will be damaged, and it will not cause greater losses.

3. It is useless to put an insulating thing on the feed, one is also conductive when it rains, and the other is due to the existence of "flashover effect", electric sparks will also appear on the surface of the insulated object under high voltage.

You can't watch TV when it's thundering, it's an outdoor antenna, and watching TV is more harmful.

First, the harm caused by lightning.

1. It is very dangerous to watch TV during lightning, and the power grid is easy to lightning, which not only damages electrical appliances, but also endangers the safety of people and property;

2. Equipped with an outdoor antenna, there is an additional lightning path, and the danger is more prominent.

Second, lightning protection during lightning.

1. During the lightning period, turn off and unplug the power plug of the TV and set-top box in advance, and disconnect the electrical appliances from the power grid;

2. During the lightning period, turn off the outdoor antenna in advance and disconnect the lightning transmission path;

3. During the thunderstorm, do not play with mobile phones and do not watch TV, just like people should avoid big trees in a thunderstorm, so as to avoid lightning endangering the safety of people and property and causing undue losses.

It's best not to watch TV when thundering, our factory used to scorch the plug boards during thunder.

Now it is generally possible to avoid lightning.

But it's better to turn off the TV.

Just in case.

In fact, as long as the outdoor antenna is not connected, the TV is used indoors, and there is no need to be frightened, because although the thunder and lightning are powerful, before entering the room, the thunderstorm clouds have already discharged with the earth. In the short discharge process, most of its huge energy is converted into heat, light and other energy, so it will not cause harm.

Usually when lightning strikes, when watching TV during the event, most of the interference on the screen and in the accompanying sound is the radiant energy of lightning, not the energy of induction or discharge. This kind of radiant energy generally does not damage the TV. However, it must be emphasized that it is dangerous to use an outdoor antenna or to watch television outdoors during a thunderstorm, and lightning protection measures must be taken if it is monitored.

When thunder, the voltage instantly becomes very large, which will cause the electric light to fire and cause a disaster. But there is usually no need to turn off the lights, because the voltage increases, and the work of the substation is suspended at the same time, that is, the power is out, so the lights at home will automatically turn off the power even if they are not turned off, which is safe.

As you know, thunder and lightning are natural phenomena that we often see on rainy days. With a flash of white light, the rolling thunder seemed to explode in our ears, and it sounded terrifying. Lightning has a certain destructive power, it can injure and kill people and livestock in an instant, destroy buildings and other facilities, and cause disasters.

Some of the statistics are even more staggering: there are about 16 million lightning strikes on Earth every year, an average of 10,000 per day. &127;If you do the math, you will be amazed to find that there are 1,800 lightning strikes per hour on Earth.

In the Linyi region of Shandong Province alone, in the 20-odd years from 1950 to 1972, an average of about 39 people were injured and killed by lightning every year.

How does lightning come about? When it rains, if the potential difference between clouds, between clouds, or between clouds and air increases to a certain extent, a violent discharge phenomenon will occur, which is called lightning. When lightning, the high temperature vaporizes the water droplets, the air volume expands rapidly, and the sound released by ** occurs is thunder.

Generally speaking, it is easy to have thunderstorms and even lightning strikes in summer.

Lightning strikes are almost inevitable natural disasters, can we just be caught with our hands tied? Can't we take some protective measures? No!

We don't have the power to control lightning strikes at the moment, but there are steps we can take to protect ourselves and our family's property. It turns out that with or without measures, with or without measures, with scientific or not, the results are very different. For example, a group of students were playing in the field when a thunderstorm hit, and several boys ran to a nearby cave to escape the rain.

Several other female students, who had plastic tarpaulins, set up to shelter from the rain under a tree, but they were all struck by lightning, and some of them died instantly. It can be seen that lightning strikes can be avoided or prevented, and the key depends on whether you have taken scientific self-protection measures.

There are two main occasions for lightning strikes, one is indoors and the other is outdoors. Let's talk about how to avoid lightning strikes in both cases.

If it's raining and thundering and you're indoors, it doesn't mean you're safe from lightning. At this time, you should close the doors and windows, turn off the electrical appliances that are in use in the home, such as televisions, hair dryers, etc., and unplug the power plugs. You also need to stay away from indoor metal facilities, such as radiators, sewer pipes, doors and windows, and away from power lines, ** lines, broadcast lines, etc., to prevent being struck by lightning.

Also, don't wear damp clothes at home, and don't lean near damp walls, which can be dangerous to you.

In case it hits your home wire or main wire, your computer, your TV hangs.

To put it simply, when thunder strikes, it may open our power line, so that the voltage rises, which will damage the electrical equipment. Let's be simple. You should understand, any electrical appliance has its working point pressure, and if it is exceeded, it will be damaged.

Ray will send a power from the limited amount and break the TV.

Are you brain-dead? Are you S B?

It's best not to watch TV when lightning and thunder are roaring. When lightning happens, high currents and voltages may enter the power supply and signals, and instantaneous high voltages and currents may damage equipment and cause danger. Now, of course, there are generally lightning protection measures.

I'm not afraid of 10,000, just in case.

It's best not to watch TV when lightning and thunder are roaring.

It should be possible, I'm just watching, the lightning is thundering outside. In fact, you don't have to be afraid of thunder, find someone to accompany you or focus on doing one thing, just forget. If it is not under a tree or in a place where electricity can be conducted, it will not cause an accident.

It is dangerous to use an outdoor antenna or to watch TV outdoors during thunder. It is recommended to cut off the power and the TV first. Sometimes thunder and lightning will enter the room through the window, so the thunderstorm is the induction lightning is when the direct lightning occurs, it is very dangerous to watch TV on a thunderstorm day, it is best not to watch.

Yes, there is something terrible about thunder, a natural phenomenon, as long as it is not in an open place, it is safe in your own house.

Thunder and lightning are best not to hit the computer, because it is dangerous to do so.

If the lightning hits near the residential area or hits a certain section of electrical equipment outdoors, it will cause the circuit voltage of this section to increase instantaneously, resulting in serious damage to household appliances.

The radio waves of lightning can also enter the television through the lines of the CCTV, thus damaging the television. Therefore, it is recommended that when thunder and lightning strike, it is best to turn off the TV, computer, refrigerator, air conditioner and other electrical appliances, and in order to prevent the voltage from being too high, you should unplug the power socket (be sure to unplug it, not just turn off the power. The computer should be unplugged from the closed circuit outlet

When thunder, lightning will be transmitted to the terminal through some communication lines or power lines, if the voltage is too high, the voltage regulator is not used. You can't turn on the computer when there is thunder, it is to prevent lightning strikes, and everyone knows this. In severe cases, it will burn the network card, especially the ADSL cat, and even the computer host and monitor.

Therefore, when thunder, not only can you not play with the computer, but you also have to unplug the network cable.

Voltage fluctuations in summer and daily thunder and lightning have a considerable impact on computers. Because at this time, instantaneous power surges and voltage spikes may occur at any time will directly test your power supply and the host, if your power supply has a protection function, the loss is small, otherwise, you just wait to be depressed. You might say:

I've never had a problem with this. However, once something goes wrong, it will be too late for you to regret it, because natural damage (force majeure damage) is not covered by the warranty. Just as I always recommend everyone to buy a good power supply, a good outlet with surge protection is also indispensable.

Precautions for computer use.

Turn on and off the computer correctly to turn on the power of the monitor first and then turn on the power of the host, and turn it off is the opposite; Never force it to shut down.

Place the computer with care, away from heat, humidity, dust, and direct sunlight.

Pay attention to lightning protection in summerDon't use the computer when it is thundering and raining, and it is best to unplug the power cord.

Avoid the influence of magnetic fields on the computer, do not place too close to the TV, speakers, power amplifiers and ** machines, at least about two meters apart.

To prevent anti-skewering, the computer is equipped with a special anti-static power strip.

Avoid humid environments and run computers that have not been used for a long time during the rainy season; When the weather is dry, increase the air humidity in the room appropriately.

I'm sure you also understand.,For the sake of your computer,Be sure to pay attention to safety.,Good luck.。。。

Not necessarily, it's rare to hear of a broken computer. I never turn off my computer because of thunder, but it's good to be careful.

However, there are still risks, such as my family's ,,, said that the computer motherboard burned out during a thunderstorm a while ago.

If you have a lightning rod near your home, or if you live in a building or a place where you live, then you generally don't have to be afraid. But if you live in a place where there is no lightning rod, and the nearby places are empty, such as rural areas, then it is best to turn off and not use them for the time being.

If lightning hits the transformer of that line in your house.

It is possible to cause a sudden increase in voltage.

By then, all the appliances in your house that are turned on will burn out.

Nor is it better to turn off the thunder if it's close to you.

But now there is a lightning protection socket Practical effect I don't know I haven't tried = =

There are two things that can happen when a TV is struck by lightning:

1. The power module of the TV is faulty, and the power supply module of the TV is burned due to the instantaneous current entering the power module of the TV through the power cord, resulting in the failure to start normally. At this time, the power module can be disassembled to detect whether the fuse is burned, whether the capacitor circuit is broken down, short circuit, etc., and the fault point can be repaired or replaced with parts.

2. Lightning enters the TV through the antenna and burns the high-frequency head of the TV, this situation can also be detected and repaired according to the above methods, if the high-frequency head is completely damaged, it needs to be replaced with the high-frequency head of the same model to solve.

3. For non-professional users, it is recommended to contact the after-sales service of the TV as soon as possible to carry out a comprehensive overhaul of the TV; Do not disassemble the machine without permission, so as not to expand the fault due to improper operation and cause greater losses.

This is the switching power supply and a short circuit, if you understand it yourself, repair it yourself, do not understand the circuit, please do not do it, otherwise the fault will expand, illuminated into a greater loss. It doesn't cost much to find a maintenance person to repair, and about 30-50 yuan is enough.

No, if it's caused by thunder, it should be **ah......Is it too much electricity, such as forgetting to turn off the TV for several days, the TV is too old, some parts are aging, and I suddenly watched it for a long time. Or maybe a little water went in, and after that, **? You'd better hire a professional, electrical appliances are not a joke, in case you don't get it right, it's too dangerous to turn on the power **!
