Chapter 143
In January 2010, a Basquiatian student was lucky enough to photograph the moment when Baidi Tower was struck by lightning. In the photo taken by this student, people can clearly see several blue streaks of lightning The arc light directly hit the spire of Baidi Tower. This scene is like a Hollywood sci-fi blockbuster.But if it is for Huaguo netizens to watch, they will definitely shout "That fellow Taoist is here to overcome the calamity"!
Two years later, in December 2012, Baidita was struck by lightning again, bringing incredible spectacle to people.

What is even more incredible is that in the following 2014 and 2016, Baidita was struck by lightning again.The time when Baidi Tower was struck by lightning is also very interesting. The interval is two years, and it is basically in the local winter.

As for the lightning strike time in winter, it is easy to understand. This may be related to the special local climate, but it is very strange that it happens every two years. Is this also happened during the period, but people did not take pictures, or No one knows what's going on in this.

But these things do not hinder the long-term observation of photographers in the future. As long as there is rain in the weather forecast, they will come to the roof of the nearby building to watch, even if it is a season with very little rainfall and a very short duration, and this time it is the summit. As it was approaching, a large number of reporters gathered here, and those young reporters who were interns or running errands were sent out.

I don't know if the weather forecast is accurate or their waiting and prayers worked. A dark cloud gradually floated in the sky, accompanied by purple flashes and faint thunder from time to time. It seems that the rain is coming today, but Lightning doesn't seem to be very powerful.

However, none of this puts any pressure on Baidi Tower. The spire of Baidi Tower is made of 4000 tons of steel, which itself acts as a lightning rod, which can protect the entire building from lightning strikes. The probability of being struck by lightning does not necessarily mean that one will be struck by lightning.

However, after all, the taller the building, the more vulnerable it is to damage from lightning strikes. Repeated lightning strikes can cause devastating damage to houses and buildings. If the intensity of the lightning strike current is too large, large-scale damage can occur.

It is understood that a lightning strike 3 to 5 kilometers above the ground can generate an average voltage of more than 1 million volts.

The world's tallest building, the Baidi Tower, soars into the sky, and the risk of being struck by lightning is not trivial. Therefore, it is becoming more and more important to measure and count lightning strikes.Therefore, on the top of Baidi Tower, a lightning monitoring system was used to detect and evaluate lightning strikes at this location.

The lightning monitoring system consists of an analyzer, connecting cables and three sensors.The sensor measurement area will determine the lightning current peak value, the maximum slope of the current waveform, the energy of the lightning current, the charge of the lightning current and other lightning characteristic values ​​according to the detected lightning magnetic field, and store them together with the date and time of the lightning strike. The sensor The optical signal is sent to the analyzer via a fiber optic cable.

Utilizing these typical lightning strike data and analyzing potential hazards in detail is helpful for better lightning protection planning, and managers can use the current readings of the previous lightning monitoring system as a reference to assess the potential of Baidi Tower's electronic and building facility systems. Conduct lightning disaster risk assessment to carry out the corresponding lightning protection plan, and notify the fire department, maintenance department and security department in advance.

As a result, Baidi Tower has survived only a few lightning strikes in the years since it was built, and each time it has remained unharmed.Even after the thunder and lightning, there will be a rainbow around Baidi Tower, which will add to its beauty and show the beauty of the combination of technological creation and natural beauty.And the tower is too high, even the rainbow can't reach the top, which is also a rare beauty pursued by photographers.

Slowly, dark clouds gradually drifted over, and there was also a drizzle of rain around Baidi Tower, and lightning began to flash frequently in the sky, purple lightning branches printed the entire sky purple from time to time, and thunder rumbled It exploded above his head, and he didn't have the "weakness" at the beginning at all.

And today's light rain is destined to surprise photographers and journalists, as well as frighten Baidita Lightning Testing Center.

In the expectant eyes of photographers and reporters, the lightning that was swaying energy in the sky suddenly turned and slashed towards Baidi Tower, directly on the spire of Baidi Tower. People exclaimed one after another, and even the camera in their hands trembled.

They did not expect that their wishes would come true today. Some of them even came here for the first time. They did not expect that they were so lucky. They captured such a shocking scene when they came here for the first time, so they cheered in surprise. There was a sound, and then another bolt of lightning struck the top of the tower, and they pressed the shutter more frequently, praising their respective gods while taking pictures.

At the same time, the people inside Baidi Tower also received the notice that Baidi Tower was struck by lightning. It is equipped with the most advanced lightning defense system in the world, and they proudly announced this, so that the guests do not need to panic. At the same time, they also released a well-positioned camera image outside the tower where there is a screen, so that Guests also get to witness this rare spectacle.

At this time, the tourists on the observation deck on the 124th floor also saw and heard this information, but their feelings were more intuitive, because they were close enough to the top of the tower, they could see the bright purple flash, and they could also feel the light of the tower. The slight vibration, so this made them very excited. Some bold tourists even wanted to go back to the outdoor viewing platform to experience the magnificence of nature more closely, but they were finally dissuaded by the staff.

I don't know if it was their illusion that the vibration of the tower body was felt. Anyway, Dong Chen only felt the vibration of his own cells. It only took a few seconds from the body to feel the lightning to the time when the lightning struck the tower. After reviewing Baidi Tower's lightning monitoring and defense system and analyzing previous lightning strikes, he did not treat this lightning strike as a dangerous event, so Dong Chen did not receive any warning in advance.

After feeling the thunder and lightning coming, Dong Chen immediately cursed in his heart to take Cui Ping away, but the place has already been occupied by excited tourists after hearing the broadcast. His physical fitness and strength have been upgraded beyond ordinary people, but facing the The crowd of hundreds of people was helpless. Although Cui Ping and he were working hard, the efficiency was not so obvious.

Dong Chen squeezed into the crowd, feeling that all the cells in his body were excited, more excited than ever before, and his whole body was hot with excitement, but the more excited the cells, the more frightened he was, because according to the law of being hacked several times, The more excited the cells, the greater the power of thunder and lightning, and the greater the threat to his own life!

He still has a lot of things to do, and he doesn't want any accidents here.

Just at this moment, Dong Chen suddenly felt palpitations, the cells in his body suddenly became quiet, and his face turned pale for a while, as if he felt something, he suddenly looked at the monitor hanging on the wall.

I saw that the intermittent lightning that struck the lightning rod instantly became a continuous lightning energy column, connected between the sky and the giant tower, and the connection point with the giant tower moved down quickly, coming directly towards the viewing platform. On the road, the electronic equipment in Baidi Tower was instantly overloaded, sparks burst out from all the electronic equipment, scorched marks were drawn on the steel, and entire pieces of glass were shattered, falling down one after another.

At this time, all the tourists were stunned, and they became chaotic in an instant. They crowded into the elevator subconsciously, and the staff couldn't calm down any more, and wanted to escape here one after another. Cui Ping also saw Dong Chen's pale face in the crowd. Want to squeeze over to protect him, but it's even more impossible in this situation.

The lightning column didn't give them much time to panic, and they came to the viewing platform directly accompanied by the sparks and glass shards from the explosion of the instrument. The last scene the tourists and staff saw here was the huge lightning column blasting in and the dazzling The flash, and the final bang before darkness!

"boom--!!"
