Super shock: In a residential area in Shenyang, a huge fireball fell from the sky and split into a tall building. What is the reason?

Super shock: In a residential area in Shenyang, a huge fireball fell from the sky and split into a tall building. What is the reason? On the evening of August 3, a "super shock! The shocking video titled "My God" was circulated when the fire dragon fell into a high-rise building, showing that a fire dragon with a height of several hundred meters suddenly appeared near a high-rise building in a residential area in Shenyang. After the fire, there were sparks everywhere. At that time, the author was a little dumbfounded. What caused this?

The video shooting location of "Fire Dragon" in Shenyang, Liaoning Province is about 1 km away from the scene of the fire dragon. According to the photographer, after the lightning, there was a loud noise in the sky, just like a bomb explosion. In an instant, an orange pillar of fire split into a nearby tall building, and the top was almost flush with the top of the tall building. Then sparks flew and fell with the wind, and the ground was a sea of fire!

The witness exclaimed "My God" and could hardly speak. Indeed, ordinary people like us who live in peacetime have never seen such a scene. It is estimated that the author can't move his legs now! Then the question is, what caused this fire dragon?

Thunderstorms in Tieling and Shenyang, Liaoning Province may be the reason. On the afternoon of August 3, Liaoning issued several meteorological warning signals continuously. It is estimated that there will be hail weather in Tieling, Shenfu Reform and Innovation Demonstration Zone and Shenyang urban area in the next 4 to 5 hours, which may be accompanied by strong convective weather such as short-term strong wind and heavy precipitation! 17: 58, Liaoning Meteorological Disaster Monitoring and Early Warning Center issued an orange rainstorm warning signal.

Shenyang has issued several meteorological warnings continuously.

The above strong convective weather is the background of today's fire dragon. According to witnesses, before the fire dragon broke out, three flashes of lightning exploded one after another, causing pain in the eardrum, and then the fire dragon broke out! Some netizens left a message, laughing that there are experts in Du Jie. Of course, this is a joke. Some professional friends said it was caused by transformer explosion! The author carefully watched this video frame by frame and found that it has no characteristics of transformer explosion!

Before the "explosion", there was a flash that directly overexposed the mobile phone, and the whole picture was white, so no substantive image could be seen. When the mobile phone drops below the overexposure threshold of CCD, it can be seen that a fire dragon has connected the high-voltage tower with the building. If the transformer explodes, it is at least several hundred meters between the high-voltage tower and the building!

The overexposed flash starts from the fire dragon connecting building, and the interval is less than 0.2S If it is an explosion, the exploded oil will be ignited after a distance of more than 200m, so the shock wave explosion speed of 1000m /s is needed, and the oil exploded by the transformer cannot reach the roof in such a short distance!

So what is the reason?

Before the official release of the investigation report, the author can only guess that it is more likely that strong wind will blow off other wires or other conductive long ropes and hang them between the high-voltage line and the building, and lead the high-voltage line directly to the lightning protection cable at the top of the building. This lightning conductor is directly grounded, and the high-voltage line is short-circuited instantly, and huge energy is erupted!

High voltage line lap short circuit

Another possibility is that lightning has penetrated the space between the building and the high-voltage tower, forming a channel, and the high-voltage electricity discharges the building in the opposite direction, but this seems unlikely. After all, lightning will lead directly to the earth and directly to the lightning rod area of high-rise buildings in residential areas!

Transformer explosion combustion site

The third transformer, which is also unlikely to explode, is theoretically filled with transformer oil for cooling. Although it is not easy to ignite, it is also flammable at high temperature and high pressure! But after the transformer explodes, it will form a fire in the same place, and watching the video is not like the transformer explosion.

A transformer in an amusement park in Nanyang caught fire after explosion, accompanied by blue and white flames.

The above is just a guess. Which expert makes a supplement, please refer to the official survey results!

Super shock: In a residential area in Shenyang, a huge fireball fell from the sky and split into a tall building. What is the reason?

On the evening of August 3, a "fire dragon" with a length of 100 meters suddenly rose near a high-rise building in a residential area in Shenyang, and there were many sparks sputtering at the moment when the flame rose. This phenomenon made everyone present at that time feel a strong shock. So, how did this fire dragon come into being?

Let's take a closer look at what happened first. According to witnesses at the time of the incident, the sky in Shenyang was overcast at that time. After several times of lightning, there was a deafening sound from the incident site, as if something had exploded. At the same time, an orange-colored pillar of fire directly hit a tall building. The pillar of fire extends from the ground to almost the same height as a tall building, and then sparks splash to the ground under the action of gravity, and the flame on the ground immediately increases. It feels a bit like an upgraded version of "Tiehua". No matter from the suddenness of the pillar, or the scale and chain reaction of the pillar, it has brought great impact on people's vision and hearing, so that many witnesses are deeply shocked, surprised and even scared to speak. No wonder, as the report said, "citizens repeatedly exclaimed: My God"!

The investigation of this incident is still in progress, and the official has not yet given a definitive conclusion. We might as well make a guess according to the shape, the speed of development and the weather characteristics at that time.

The typical characteristics of this pillar of fire are not surprising: first, expect unexpected things to happen; Second, the height reaches hundreds of meters; Thirdly, the time from the first capture of the flame to the pillar reaching the roof should be about 0. 1 sec, which is developing very rapidly. Fourth, there were several lightning phenomena before the pillars were produced.

According to the above characteristics, we can at least infer that the generation of this pillar of fire is inseparable from electricity. On the one hand, fires caused by electricity occur suddenly and spread very fast. On the other hand, when the fire pillar is caused by electricity, it will also cause sparks, especially for high-voltage lines and transformers.

Combined with the lightning and gale warning information released by Shenyang on the 3rd, we can see that the weather in Shenyang was very unstable that day, not only with frequent lightning, but also with strong convective weather such as thunderstorm and gale or hail. Finally, the facts also confirmed the meteorological early warning information. Last night, the instantaneous wind force reached 8-9 in some areas of Shenyang, and lightning also appeared frequently. In this case, it will undoubtedly have a certain degree of impact on the urban power infrastructure.

It is very likely that one or more power supply lines were blown off by strong winds, and some power supply lines fell between high-voltage lines near buildings and buildings. It happens that the high-voltage line suspended in the building just touches the lightning protection device on the roof, thus generating a strong potential difference between the high-voltage line and the lightning protection device, which is a typical short-circuit problem, thus releasing huge energy in a very short time, and then converting it into heat energy to form a pillar of fire.

Of course, there is another possibility, similar to "ball lightning". At the same time, lightning strikes several small water droplets in the air near the bottom of the ground, forming dendritic lightning with very strong electric field around the water droplets, which directly expands the space in this area, including the water droplets themselves. In this very short time, if some acrobatics such as dust fall into small water droplets, the resistance of current through dendritic lightning will increase continuously, which will stimulate the ionization of water.

Some netizens said that the transformer exploded. If you watch the video of the explosion carefully, there are some obvious differences from the explosion of the transformer. The most important thing is that the scope and development speed of the explosion do not match. If it is an explosion of a transformer, a huge fireball will be generated around the explosion site, and a pillar of fire hundreds of meters high will not be formed in such a short time as 0. 1 second.

As for the real cause of the pillar of fire, let's wait for the results of the investigation. Interested friends, please leave a message at the bottom, and we will study together.

I used a personal experience to illustrate that this was a lightning strike. In mid-May of July1,the wireless power plant where I just worked for half a year was moved to the new site of Gao Qiao, Zunyi, which was a minefield. Because there are more women than men in the workshop, I watched the vigil with the workshop monitor that night. 10 or so, it's sultry when it's about to rain. I just climbed onto the assembler's desk and just lay down. At this time, the sky continued to thunder and rolled with dazzling lightning. A bright red fireball penetrated the gable of the workshop, with a thickness of 37 cm (the next day I saw that the hole was estimated to be 80 cm in diameter), fell from the sky and landed on my lying desk. The wire and steel pipe under the cement floor was blown out of the ground, ran along the steel pipe to the switchboard with a width of about 2 square meters on the outer wall near 10 meter, and was blown to pieces. The flying sawdust stabbed the monitor in the back with his back to the switchboard 6 meters away. Immediately after the lightning strike, it began to hail, damaging all the cement tiles on half the roof of Jorda workshop. In the middle of the night, from the workshop through the half-empty roof, listening to the occasional low animal roar in the distance, I had to close the door and hide in a lot of insulation in the corner until dawn. When I came home the next day, the big wooden bridge on the Xiangjiang River in the former regional hospital was washed away, so I had to cross the Hongjun Mountain and cross the river from Shilong Bridge in Zunyi Hotel to my home near the Zunyi Conference site. The city I saw along the way was a mess, and I will never forget this memory! Fortunately, I survived. I was 16 years old that year! So the red lightning with tail discussed by everyone is what people call destructive rolling thunder! The city has expanded a lot in the past 50 years. At that time, Zunyi Expressway toll station was built near the factory. I have retired for several years, and this right should be left as a memory of Zunyi.

This is an unusual natural phenomenon. When the air is too wet and the air pressure is high, lightning can cause deflagration, which can make the residual oxygen atoms in the surrounding air produce afterburning. This phenomenon often occurs in places where the airflow channel is not smooth. This is exactly what happened between buildings.

The fire dragon that fell from the sky in Shenyang split into a tall building, because lightning hit the high-voltage line and caused a fire, and sparks came out instantly. August 3 17: 53, near a residential area in Tiexi Economic Development Zone, Shenyang, Liaoning Province. Lightning strike caused the high-voltage line to catch fire, and sparks flew in an instant. Residents nearby heard a loud noise from the sky, and then a fire dragon split at the tall building.

The accident scared the nearby residents to scream. Fortunately, there was no fire and no casualties because there were no combustible materials near the incident site.

Afterwards, I learned from Shenyang power supply department that lightning strike did not cause damage to high-voltage lines. At present, the power supply in Shenyang is normal. I didn't know how important peace was until it was thrilling.

The fire dragon falling from the building in Shenyang is a natural disaster. Fortunately, there are no serious consequences. An electric power worker made a preliminary analysis from the scene: a fire dragon was conducted from the air to the ground because the steel bars in the high-rise building under construction were exposed and acted as conductive conductors, which did not cause a fire.

The natural disaster was caused by the collision between lightning and high-voltage lines. Humans can't change lightning, only high-voltage lines. Can you coat a layer of material on the high-voltage line to prevent lightning strike?

In the face of natural disasters, mankind is so weak. I can only pray silently that the natural disaster will not come again. May the mountains and rivers be peaceful, and may the world be peaceful.

Although human beings can't stop natural disasters, they can take various measures to prevent them. With the development of science and technology, these measures will be more and more.

The shocking effect of the blockbuster "Jin Fei Viewpoint" is really released in reality, which can be described as thrilling! So what is the reason why a huge fireball fell from the sky and split into tall buildings in Shenyang?

Let's take a look at what happened first: on August 3, a resident near a residential area in Shenyang heard a loud noise, and then a pillar of fire crashed into a tall building, suddenly sparking, scaring local residents to exclaim.

Then the reason is very clear, but we still have to pay attention to the recent high incidence of lightning season, and we may be hit by lightning at any time and anywhere. Once casualties are caused, the consequences are unimaginable!

In particular, lightning concentrated high-voltage lines will not only damage the equipment, but also damage the power supply system. There are often news that high-voltage lines are tripped by lightning in mountain power supply lines.

Then the high-voltage line is changed to buried ground wire, but the disadvantage of buried ground wire is short circuit fault at the joint soaked by rain, which is more likely to cause tripping. Therefore, to prevent lightning strikes, we can only pray that lightning can be smaller and can be eliminated by lightning rods.

So how can we prevent lightning damage in the high lightning season in summer? 1, don't take shelter from the rain on the roof or under the tree.

Roofs and trees are often struck by lightning in the rainy season, so it is purely an act of death to take shelter from the rain in these places. If there is no place to go, it must be more than 3 meters away from the trees.

2. Don't move too fast.

It is best not to run in thunderstorm weather, let alone drive a motorcycle or ride a bike. Moving fast in thunderstorm is easy to be struck by lightning, and running fast in rain is also dangerous.

Step 3 stay away from metallic substances

When walking in the rain, don't hold an iron umbrella or take a metal toy. When sheltering from the rain, observe whether there are exposed metal objects or electric equipment such as water pipes and gas pipes around, and don't stay near iron fences, metal clotheslines, overhead metal bodies and railway tracks.

4. Pay attention to wearing shoes in thunderstorm weather.

Walking barefoot in thunderstorm weather will increase the possibility of being struck by lightning. Playful children should put on shoes immediately, or put insulators such as plastic on the soles of their feet.

5. Don't take a bath.

It is not advisable to take a bath when thunder and lightning strike, because the water pipe is grounded by lightning protection. People living in high-rise buildings should also pay attention to closing doors and windows to prevent lightning from hitting the room directly and preventing the invasion of side flash and ball lightning. Tell children not to stick their heads and hands out of the window and not to touch the metal frame of the window with their hands.

Have you memorized all these little common sense? Stay on the sofa at home in thunderstorm weather! On August 3, a residential area in Shenyang was struck by lightning, and a huge fireball fell from the sky. The scene is very shocking and horrible. According to the photographer, after the lightning, there was a sudden loud noise in the sky, just like a bomb explosion. In an instant, an orange pillar of fire crashed into a nearby tall building, and the top was almost flush with the top of the tall building. Then sparks flew and fell with the wind, and the ground was a sea of fire. I think the fireball produced by lightning explosion is quite dangerous if someone is nearby, because when lightning explodes, it forms a large equivalent shock wave, which is easy to catch fire and cause harm to people and animals. Regarding the causes of lightning explosion and fire, I think there are the following points:

First, obviously, this is an ultra-high voltage discharge phenomenon. That is to say, the strong current brought by lightning instantly passes through the conductor (high-rise building), resulting in ultra-high voltage above three Qian Qian volts. In Super high voltage test, there will be similar fire dragons, but the difference is that one is from bottom to top and the other is from top to bottom.

Second, it is possible that ball lightning hit the building and ignited the insulation layer of the external wall. In order to save costs, most builders use flammable foam boards for external wall insulation, and some external wall insulation boards have caused many fires.

Third, because the building insulation material is wet and easily conducted by rain, there are flammable residues such as formaldehyde, which will become powdery sparks after being struck by lightning. The principle is the explosion principle of the gas tank of the charge bomb.

Since there is a fire, it means something is burning. If it's just lightning, it should be impossible. It seems that the high-voltage line is short-circuited. Maybe you can ask the power company.

Build tall buildings to avoid density. Building a high-rise building, through this lightning strike, provides us with new thinking on experience and prevention: to build a high-rise building again, the high-voltage line near the high-rise building must be designed underground, and there is no high-voltage line on the ground.

Astronomical phenomena are frequent. It snowed in Beijing a few days ago in June, and floods in the south continued. . . . . Eradicate evil and God bless China!

This is a natural phenomenon. My cousin saw it with her own eyes. In summer, he saw a fireball floating towards him. He turned and ran, and the fireball exploded at once. The loud explosion almost deafened his ears. At the same time, one of his neighbors got an electric shock, and so did his neighbor.

It's not a strange thing that the huge fireball in Shenyang was struck by lightning. The phenomenon that high-voltage lines in residential areas are not connected with lightning is common at ordinary times, but it doesn't always have such a big reaction. Sometimes there is a power outage at home on rainy days, which is the reason.

High-voltage wires are all connected to the ground wire. The instantaneous voltage of lightning is so high that no electrical appliance of human beings can resist lightning strike. Therefore, people can only find ways to introduce lightning into the ground and let the earth absorb this lightning. This is the principle of lightning rod in our life, and the pole of high voltage electricity acts as the ground wire. When lightning strikes a wire, it is said that these currents are introduced into the ground through poles.

This time, because lightning struck high-voltage electricity in residential areas, high-voltage poles could not be erected in residential areas, so a large section of wires were pulled in mid-air. If lightning strikes this conductor, there is no way to spread it into the ground through the pole in time, so the energy of the whole lightning is absorbed by the conductor, which leads to the instantaneous high temperature of the conductor, and the carbon inside quickly burns out the main body, resulting in a large number of sparks.

Because it is a high-voltage line, it will not be directly connected to the residents' electricity, but will be connected to the nearby transformer first, so this incident did not cause any casualties.
