What are the hazards of lightning? What are the benefits of lightning?

The hazards of lightning are generally divided into two categories: first, the thermal effect and electrodynamic effect of lightning directly hitting the building; The second is the secondary effect of lightning, that is, the electrostatic induction and electromagnetic induction generated by the lightning current. The specific hazards of lightning are as follows:

1. The high-voltage effect of lightning current will produce an impulse voltage of up to tens of thousands of volts or even hundreds of thousands of volts, and such a huge voltage will instantly impact electrical equipment, which is enough to break down the insulation and cause a short circuit in the equipment, resulting in direct disasters such as combustion and **.

2 The high thermal effect of lightning current will release a strong current of tens to thousands of amperes, and produce a large amount of heat energy, and the heat at the lightning strike point will be very high, which can lead to metal melting, causing fire and **.

3. The mechanical effect of lightning current is mainly manifested in the occurrence of **, distortion, collapse, tearing and other phenomena of the lightning struck object, resulting in property loss and personnel**.

4. Electrostatic induction of lightning current can make the conductor of the hit object induce a large number of charges contrary to the nature of lightning, and when the lightning disappears and has no time to disperse, it will produce a very high voltage discharge phenomenon and lead to fire.

5 Electromagnetic induction of lightning current will produce a strong alternating electromagnetic field around the lightning strike point, and the current generated by the induction can cause local overheating of the transformer and cause fire.

6. The intrusion of lightning waves and the counterattack effect of high voltage on the lightning protection device on the building will also cause the power distribution device or electrical line to break and burn, resulting in fire.

It often causes serious fires such as forest fires; destruction of buildings; endanger the lives of humans and other animals; affect the use and life of some precision instruments; impact aerospace and military activities, etc.

Some of the insulators will be damaged by the conductors.

Thunder? You're talking about that little game! I've been playing for a long time and I don't feel any harm, huh? When I first played, I was a little fascinated, but after a long time, it naturally won't.

It's going to muddy what you hit, and it's going to have green smoke.

1.It is a non-polluting energy source. Lightning can discharge from 1 to 1 billion joules at a time.

In the Chinese idiom, there is the word "thunder and thunder" (霆: splitting thunder, jun: the ancient unit of weight, equivalent to 30 catties at that time).

With this huge impact, it is possible to tamp the soft base, which can save a lot of energy for the construction project. According to the principle of high-frequency induction heating, the high temperature generated by lightning can be used to expand the moisture in the rock, so as to achieve the purpose of crushing the rock and mining the ore.

2.Thunder and lightning can cure diseases. After each thunderstorm, the gas molecules in the air will separate negatively charged negative oxygen ions under the action of the lightning field.

Researchers have tested that after a thunderstorm, there are more than 10,000 negative oxygen ions per cubic centimeter of air, while in downtown areas on sunny days, there are only a few dozen negative oxygen ions. Experiments have shown that negative oxygen ions, which are called "vitamins of the air", are good for human health.

3.It can make nitrogen fertilizer. In the event of lightning, the lightning channels in the atmosphere can be several kilometers long, the temperature is extremely high, and there is a large amount of nitrogen and oxidation to synthesize nitrogen dioxide.

The resulting nitrogen dioxide dissolves in rainwater and becomes nitric acid, which is not concentrated in high concentrations.

It falls into the soil and combines with other substances to form saltpeter.

It is a gratuitous gift from nature to human beings.

4.Thunder and lightning can be a predictor of the weather. Because China is located in the westerly wind belt, most of the clouds and rain move from the west to affect the local area. "The fire door is open in the south, and there is rain in the north.

5.Thunderbolt prospecting. Lightning strikes objects that are prone to conduction, and this feature provides clues for geological prospectors to find metal deposits.

The benefits of thunder and lightning, chasing thunder and lightning is so dangerous, we can't accept it for the time being, he can't use him.

1. The hazards of lightning are: personnel, destroying buildings, power supply and distribution systems, communication equipment, causing forest fires, causing computer information system interruption, storage, oil refineries, oil fields, etc.

2. More than 2 3 of the victims of lightning were attacked outdoors. Two out of every 3 of them survived. Eighty-five per cent of those killed by lightning were women, mostly between the ages of 10 and 35. Most of the deceased took refuge in thunderstorms under trees.
