In the large conference room, everyone lined up according to the seats. On the left side of the long table were comrades from Fengzhou, and on the right side were investigation teams led by Nangang. The scene was very solemn.

Judging from the previous performances, Zhang Yifu has already predicted that Fengzhou cannot admit that there were any mistakes, but the investigation team just wanted them to admit that there were any mistakes.

No one has mentioned the questions about the equipment and the switch itself. People from Fengzhou did not mention it, and people from the investigation team did not mention it. This tacit understanding makes people feel strange.

Zhang Yifu wanted to mention it, but he really didn't mention it much in his position. Just be a good audience and listener.

As for Xia Xue, fortunately she doesn't understand the equipment at all.

Looking at Yao Xinyu again, he said what he would do next. In short, don’t give him any reason to push himself into the trap.

On the surface, two groups of people were sitting in line at this time, but in fact, Fengzhou was like a solid fortress. Miao Delin stood at the top of the city and said that he would hold on for ten thousand years. Nangang and Ou Wei on the opposite side turned into two heavy three guns, which was about to break through lightning.

Zhao Wenyuan was caught in the middle, and seemed to be the party responsible, but in fact he was not biased. He even favored the power plants that were familiar with him and the front line of production. After all, everyone has been dealing with him for so long, and he has feelings for no benefit. Anyone with discerning eyes can see that Zhao Wenyuan's position is different from the previous seemingly serious and stern, and he is still humane.

Zhang Yifu has experienced many baptisms and has the ability to see the essence through the phenomenon, but Xia Xue just turned on the other hand, and ignored the essence and rushed directly into the pit of truth.

With Nangang coughing, the shells entered the chamber and the battle began.

The wave recording chart before and after the accident was distributed to everyone, and the wave recording analysis began.

The old-fashioned printing paper with round holes on both sides is smelly and long, and nine incomprehensible waveforms are recorded on the paper, which extends like this smelly and long.

This pile of ghost things similar to Arabic is definitely difficult for outsiders to understand, and even Zhang Yifu was so angry that he saw it.

Nine waveforms record the changes in the three-phase current of the No. 1 output line ABC, three-phase voltage of the ABC, and three-phase voltage of the busbar.

If you look carefully, you will find that the waveform before the accident was very stable sine waves. At a certain moment, the b-phase current of the No. 1 exit line suddenly increased. As the phase ac current increased abnormally, all voltages of the bus and No. 1 exit line dropped to almost zero. This is the consequence of the grounding fault.

All in all, everything was normal before that b-phase switch exploded.

At this point, the interference of other factors is eliminated. It cannot be caused by the failure of other equipment in the power plant. On the contrary, it is definitely everything caused by the explosion of the switch.

Although this eliminates the possibility of chain failure, it still helps the current problems.

It is still a mystery that the Mao will explode.

After a brief discussion, we reached an agreement - this picture can be thrown away.

So, without any other clues, the person who had a childbirth again raised the possibility of an accident that had not been "closed at the same time". Although Xia Xue was straightforward and stunned, she was not a fool. She had already refuted it and was disdainful to refute it for the second time. If you continue like this, it is your problem. I have no intention of fighting with you.

Then the arguments about the closing of the same period have been vague and entangled, and they have been fooled by "some kind of inconsistency", "emergency situation" and other vague ways, hoping to subdue the failure.

But if this happens, Miao Delin will not agree, nor will the people in Fengzhou.

"Dear leaders, the probability of an accident during the same period is really slim, and the situation of the waveform chart is so clear at a glance. If you talk about it, you can only trip at most. It is impossible to explode!" Miao Delin insisted, but he refused to admit it and refused to accept it.

After all, this is the last chance to not delist.

"Old Miao, calm down." Zhao Wenyuan waved his hand and said, "It's not confirmed yet. I'm just discussing the possibility. From my own perspective, I can't fully agree that it was caused by the failure to close the switch at the same time."

"Hmph." Nan Gang didn't say anything, but snorted and subconsciously took out a cigarette, but suddenly considered his position and stuffed the cigarette back.

Those who work in the security supervision department should not take the lead in violating the rules, even if they violate the rules, they cannot be the present.

Seeing that Lao Miao was stubborn, Ou Wei also said: "Indeed, it is impossible to determine this problem 100% now, but in today's situation, this is the only possibility."

"Director Ou, it's really impossible!!" Miao Delin was about to cry, "Otherwise, let's use facts to speak, adjust all the parameters, do a few experiments, and see what exactly!"

Anyone who understands it knows that even if it is a problem at the same time, it is a low-probability event. 10,000 trials may not necessarily trip, let alone explosions.

Ou Wei laughed reluctantly and replied: "Director Miao, how can such a small probability of failure be proved by experiments?"

Miao Delin looked so terrible that he really didn't know how to clear his grievances.

In fact, the investigation and analysis of power accidents does not necessarily have results every time. Occasionally, there will be situations where nothing can be found. In the end, it can only be blamed on low-probability events or unknown reasons. However, in this case, it will still be attributed to on-site management errors, and production personnel will always take the blame, which means they will still be delisted.

Especially in the current situation, there is no problem with other switches. The switch that has problems has no body and no evidence of death. There is also a black box that crashes, and the switch is not installed.

So, the car took turns to go and entered the stage of tug-of-war.

Half an hour passed in a daze. Just when Zhang Yifu was already sleepy and about to fall asleep, the people in the investigation team were finally tired and annoyed, and had no intention of quarreling.

Nangang waved his arm and said, "Since this is the case, I don't think there will be any result. Either the mistake of the on-duty staff failing to close the switch at the same time, or it is a poor production management, poor equipment maintenance, and failure to comply with process specifications. Miao Delin, you choose."

"………………” Miao Delin looked at Nangang blankly, not knowing what to say.

At this time, sitting on the edge, Youyou, the deputy director of the Wuhe Power Plant, said: "It's not the first time Director Miao has encountered such a thing, right?"

"What does it mean?" Miao Delin was deeply puzzled.

"I just remembered it suddenly." The deputy factory manager pursed his lips and said, "About four or five years ago, Fengzhou skipped the gate once. There was no big problem. A few people came to investigate, and I was also among them. At that time, I thought about everything I could think about and everything I could check. I couldn't find the reason. In the end, I could only determine the reason and give the on-duty staff a punishment."

The chief engineer at Fengzhou Power Plant immediately said: "Yes, this kind of accident with unknown reasons can happen occasionally, and this time, not..."

Before he could finish speaking, the deputy factory director waved his hand and smiled at Miao Delin: "Old Miao, have you really forgotten?"

Miao Delin thought a little when he heard this, and then his expression suddenly froze and he couldn't say a word.

"I think many people here remember it, right?" The deputy factory manager looked around and said sarcastically, "Later, after a meeting, we had a dinner and we had a drink, Lao Miao drank too much. He was happy to explain the whole story. He changed the operation records before the investigation team came, restored the correct connection of the relevant equipment, and filled the fuse, which made the investigators unable to find out anything."

His words reminded everyone, and several people nodded and remembered this.

A bolt from the blue! Adding damage to the wrong person!

Don’t be happy when you are in a happy life! When you are in trouble!

Miao Delin was so arrogant for several years, but he didn't expect to fall into this matter and left a trap after drinking. Just talking about that matter, the problem was not serious. It was said by the power plant privately, and it was over. No one caught the nothing that happened.

But under the current circumstances, it is equivalent to having a criminal record! A habitual offender! It is enough to die ten thousand times.

The deputy director of the Xianhe Power Plant continued: "Actually, that matter is not a big problem. After we heard it, we just smiled it. But now, it is an accident investigation, and the cause is unknown. Moreover, it is such a big accident. Lao Miao, you haven't touched the scene, right?"

Miao Delin's face was already covered in sweat, her oily face was shiny, her eyes were full of hatred and regret, and she only replied: "No, absolutely... no."

Who believes it?

Even Zhang Yifu was a little disbelief.

Did it! I'm still thinking about how to help you. After making trouble for a long time, you are a fraudster? I'm moved by Bai Bai and promiscuous. You deserve it!

Zhang Yifu is not happy, let alone others, who is so soft and kind.

Especially Nan Gang, after hearing this, his face drooped a lot and was about to fall off. He couldn't hold it in his arms, so he took out a cigarette and lit it, then pinched the cigarette butt and pointed at Miao Delin and said, "Okay, okay, have the ability, experience, and have the solution!"

"Director Nan... let's not beat him to death." Zhao Wenyuan saw that his leader was already angry and quickly persuaded, "At that time, Lao Miao was still young and talked nonsense after drinking, and that accident was just a small crew to trip briefly..."

Bang!

Nangang smashed his fleshy palm on the table, and the entire conference room was aroused, and even Zhang Yifu's sleepiness was swept away.

The director looked at Miao Delin hard and said coldly: "Well, it's not bad. At that time, the small crew tripped, which made him deceive him. Now he is old, he is so good. He has gained skills. He just gave me a full network oscillation!"

"..." Zhao Wenyuan knew that no matter how much he persuaded him, it would be useless.

Now, it can't be saved.
Chapter completed!
