How does lightning conduct underground through lightning rods without injuring people?

Due to the extremely low resistance of the lightning rod, the resistance of the human body is much higher than his. It can be thought of as a lightning rod that short-circuits the lightning through the body's circuitry. So as not to hurt anyone.

It doesn't seem like a hit problem, right?

The principle of a lightning rod is as follows.

In thunderstorm weather, when there are charged clouds above the high-rise building, the lightning rod and the top of the high-rise building are induced a large number of charges, because the lightning rod needle is the key tip of the car, and when the electrostatic induction, the conductor tip always gathers the most charge In this way, the lightning rod gathers most of the charge The lightning rod forms a capacitor with these charged clouds, because it is sharper, that is, the area of the two pole plates of this capacitor is very small, and the capacitance is very small, that is to say, it can hold very little charge and it gathers most of the chargeTherefore, when there is more charge on the cloud, the air between the lightning rod and the cloud layer is easily broken down and becomes a conductor In this way, the charged cloud layer forms a passage with the lightning rod, and the lightning rod is grounded again The lightning rod can guide the charge on the cloud layer to the earth, so that it does not pose a danger to the high-rise building, and ensures its safety and closure.

The lightning rod can be said to be a great invention, it can reduce people's losses to a certain extent, lightning has a characteristic is that it is easy to hit relatively high objects, and the role of the lightning rod is to attract the surrounding lightning to gather here when the lightning comes, and then the lightning will be transmitted to the ground through the lightning rod, so as to achieve a lightning effect. However, it is worth mentioning that the installation of lightning rods must meet certain requirements, and it is not possible to find unprofessional people to install them, if they do not meet the requirements, then the opposite effect may be achieved. This kind of lightning protection facility is more common in the city, but it has not yet been popularized in the countryside, so many places in the countryside will still have the problem of lightning strikes.

Although the lightning rod is called "lightning protection", it can actually lead lightning, it can attract the lightning that may hit the building to itself, and then transfer it to the ground with infinite resistance through the ground wire, so as to eliminate the damage of lightning and play the role of "lightning protection" for the building, so it is called a lightning rod.

The role of a lightning rod is to protect against lightning. Its principle is to direct lightning to discharge electricity towards the lightning rod, which directs electricity to the earth.

In fact, the role of lightning rod is precisely to guide lightning, and its original English meaning is also lightning rod, but because of the wrong translation, it will be known as a lightning rod by us.

The lightning rod is a lightning guide, which can play a role in guiding the surrounding lightning into the ground and play a protective role!

It should be said that it is not true.

The lightning rod has now been renamed the lightning rod in the national standard, which is actually more in line with its actual role, that is, lightning guidance.

The lightning rod raises the ground potential, which is equivalent to a tall person standing there, and is more likely to be hit by lightning than the object next to it, and the lightning will be attracted to it, and the object next to it will be safe. However, in fact, it only plays the role of lightning guidance, and as for how the lightning current is shunted and discharged, the lightning rod cannot play a role.

If you take eating as an analogy (as a foodie, this is a basic quality), the role of the lightning rod is equivalent to making a good meal, as for whether you eat with chopsticks, with a knife and fork, or with your hands; It is not up to it to decide who it eats, how much it can eat, whether it will be wasted, etc.

The new lightning rod used in the United States today is shaped like a feather duster, and its center is a tube, and 2,000 thin wires lead out at the top, and the wires are radial, which can dispel the static charges gathered around the building, and has a strong ability to avoid the formation of lightning. The semi-conductor lightning suppressor invented by Professor Xie Guangrun in China is also a new type of lightning protection device. When a live cloud hangs over a building, the lightning suppressor emits a 1-meter-high corona spark that shoots straight into the clouds to neutralize the electricity in the sky.

In the event of a lightning strike, a switchgear on the lightning suppressor protects the building by blocking the huge current.

During thunderstorms, we sometimes see some towering trees being knocked down by lightning, while some of the surrounding towers, high-rise buildings and other high-rise buildings are unharmed. And under the same circumstances, the safety of high-rise buildings is probably due to lightning rods.

On many towers, there is something made of metal that looks like an embroidery needle and the needle stands upright, which is a lightning rod.

So, why does this thing that looks like an embroidery needle and does not look amazing have such a great "magic" and can "avoid lightning"? Originally, the lightning rod should be called "lightning rod". In a thunderstorm, when there are charged clouds over a tall building, a large amount of charge is induced on the lightning rod and the top of the tall building.

In this way, the lightning rod gathers most of the charge.

The lightning rod forms a capacitor with these charged clouds, and because it is sharp, that is, the area of the two poles of the capacitor is very small, and the capacitance is also very small, which means that it can hold very little charge. And it gathers most of the charge, so when there is more charge on the clouds, the air between the lightning rod and the clouds can be easily broken downBecome a conductor. In this way, the charged cloud forms a path with the lightning rod, which in turn is grounded.

A lightning rod can guide the electrical charges on the clouds to the earth, so that they do not pose a danger to high-rise buildings, ensuring its safety.

Because it is constructed to effectively conduct electricity, it is able to absorb the huge amount of energy in lightning.

The lightning rod leads a wire into contact with the ground, and he releases the tremendous energy of the lightning to the ground.

Because lightning is attracted by these tiny conductors, and then the lightning rod transmits the energy underground.

I think the main thing is to drain electricity to the ground, so that it can conduct electricity better.

At that time, it was because it was connected to the earth, and then all the energy was transferred to the earth.

Instead of absorbing the lightning, he released some electrons to channel the lightning into the earth.

They rely on their own steel attributes, and their own properties are that they can conduct electricity, so they will conduct electricity.

This should be the greatness of technology, it is the power to attract lightning, and it is highly conductive.

The lightning rod is made of special materials, and it has a special structure.

One is black lightning, which is much more harmful than ordinary lightning, and it will be easy to produce **, the danger factor is extremely high, and there is also a ball lightning, which will be accompanied by some strange sounds when it appears under normal circumstances.

The lightning rod is difficult to resist, and the powerful and awe-inspiring lightning will appear a bright light, which is more of a kind of fear, and this lightning makes people feel very small, because this phenomenon will be accompanied by the release of energy, and will also produce a large amount of high temperature and current, which will cause serious damage to the human body.

Awesome lightning is actually a phenomenon of intense electrical discharge between clouds, between clouds and ground, or between parts of the cloud.

The common one is usually a line of lightning, which is like a tree branch with branches, meandering. Banded lightning is similar to linear lightning, except that the bright channel is wider and looks like a brighter bright band.
