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?

"Fire Dragon" in the Sky of Shenyang, Liaoning Province

The video shooting location is about 1 km away from the fire dragon scene. 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 predicted that in the next 4 to 5 hours, there will be hail weather in Tieling area, Shenfu reform and innovation demonstration zone and Shenyang urban area, 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!
