This morning's class is a relay protection class.

As everyone knows.

This is a slightly technical level course in the power system, in the past, when I was in college, the vast majority of people failed the course, it was this course, but it was said to be the nightmare of the power people, known as the class of death.

Before class, the head teacher reminded everyone that they must pay attention to the lecture, because this teacher is a technical expert who loves the past company, a top-notch technical expert in the city company, and one person has a number of patents, and has published several electricity books.

It sounds scary.

And the head teacher also said that this teacher is very strict, and he likes to ask questions in class, and when they first trained, they were most afraid of taking his class.

With these warnings, everyone came to this class neatly.

Unexpectedly, this teacher is still an acquaintance of Chu Yang, that is, the bald and cold-faced interviewer with whom he discussed neutral points and small problems during the interview, Wu Zhiquan Wu expert.

He didn't talk nonsense when he came up, he started talking directly, and he said that it was all real dry goods, line failure, protection overcurrent II action, unsuccessful reclosing, analysis of short-circuit current, judgment of fault point.... These sounded very useful to Chu Yang.

But for ordinary people, it's very boring, because they can't understand it at all, and if Chu Yang hadn't worked for more than ten years in his previous life, he would have half understood, because the things in the book are too one-sided.

And this expert Wu can only engage in technology, and his speech is not very interesting, and it makes people drowsy, he probably also discovered his own problem, so he asked questions very frequently, so as to make everyone concentrate.

"Liu Jiayan, get up and tell me, what is the main protection of the line, and what are the backup protections?" Expert Wu began to ask random questions again, which made everyone panic.

Because his problem is too difficult.

Liu Jiayan's heart was higher than the sky, but after standing up, she couldn't speak, her eyes were panicked to the extreme, this question was really out of line for her.

"I don't know this, are you a power major?" Expert Wu's temper came up, and he asked a few questions just now, and almost no one could answer them.

Liu Jiayan blushed, and muttered aggrievedly: "I~I~ am a foreign language major." ”

Expert Wu didn't give any face, and shook his head directly: "Now any crooked melon and cracked date can really enter our company." ”

After Liu Jiayan sat down, her eyes were red, which was too aggrieved.

"Does anyone know?" The aura of Wu University expert is five meters eight, and it is still quiet below.

"Isn't it, you don't know any of you about such a simple topic? It seems that there is no need for me to continue this lesson, and I am also playing the piano to the cow to tell you. ”

This expert Wu does have a bad temper, and the subtext of this sentence is that you are all waste.

Let these new employees bow their heads in shame and dare not speak, Chu Yang didn't want to be in the limelight, because Chu Yang knew that the level of skill really didn't have much to do with promotion.

The skills are too good, but it will restrain you, this what kind of Wu expert, Ling seems to be very awesome, but the administrative level is very low, and there is no one under him, at most a few apprentices.

But when he said this, Chu Yang couldn't bear it, these words had already touched the depths of Chu Yang's soul, and in his previous life, Lao Tzu was also a quasi-expert-level skilled hand.

"The main protection of the line is longitudinal protection, and the backup protection is divided into near backup protection and far backup protection, mainly distance protection, zero sequence protection, direction protection and failure protection."

Chu Yang stood up slowly, his voice was not loud, but it was very penetrating, everyone heard it very clearly, everyone was shocked, and it seemed that they had seen the dawn.

Expert Wu looked up at Chu Yang, frowned, didn't recognize Chu Yang, and continued: "Flip the book, right, then you go on, there are several ways to reclose." ”

He felt that Chu Yang had just flipped through the book.

"Reclosing is divided into four ways: comprehensive reclosing, triple reclosing, single reclosing and deactivating reclosing."

"What are the characteristics of a single-phase ground fault in a line?"

"The voltage of the faulty phase drops to zero, and the voltage of the non-faulty phase rises to the line voltage." Chu Yang almost came out, his expression was calm, his eyes were firm, these were too easy for himself, this was pediatrics at all.

Expert Wu's eyes changed, stared at Chu Yang for a while, and said gently: "You are Chu Yang from the Hydropower Institute, you were the one I interviewed at the beginning." ”

Chu Yang replied, "Yes." ”

Expert Wu nodded and replied arrogantly: "You're okay, you finally have someone who understands something, sit down, I hope the rest of you can learn from our Chuyang classmates." ”

.....

When it was time for class to end, everyone breathed a sigh of relief, and Chen Shizhong and Xu Hongyi all came around and said: "Chu Yang, you are awesome, you have withstood the bald fire alone." ”

"Chu Yang, how the fuck do you know so much, I flipped through the books, and I haven't studied in these universities."

'yes, don't your textbooks be different from ours?' ’

"You can't read books, you can understand more." Chu Yang can't say that he was reborn.

Over there, Li Zhiying also looked at Chu Yang, showing a pleased smile, only Liu Jun was gritting his teeth, this Chu Yang seemed to be getting more and more prestige in the class, which was not a good thing.

.........

This training course is not long, but it is not short.

A group of strong-blooded men and women are locked up in a base for training, if there is no love and love.

That's certainly not possible.

In fact, many boys are interested in Li Zhiying.

But knowing that the other party is a municipal company, many county-level companies are discouraged, because everyone knows that the starting point of a municipal company is much higher than that of a county-level company, and an ordinary employee of others is equivalent to the commissioner below.

Boys are often cowards in their feelings, after all, they are a minority of people who face difficulties, and when they go out of society, love is often mixed with bread, not just love.

In this way, Liu Jiayan of Butai has been sought after by most boys, which makes her a little fluttery.

I thought I was better looking than Li Zhiying.

Always dangling in front of Chu Yang.

The most fearful thing about people is that they don't have self-knowledge.

.....

Halfway through the training process, some boys began to complain that they didn't have supper to eat, they were hungry at night, and they were going out to buy dry food instant noodles, and some girls said that they were injured and wanted to go out to buy hemostatic patches.

Because of the rules, you are not allowed to go out casually, so the head teacher decided to send a man and a woman out shopping.

Plausible.

Chu Yang, as the class leader, stepped forward without a doubt, on the girl's side, Li Zhiying, who had always been calm and calm, saw Chu Yang go, and actually volunteered to go, which was surprising, and the head teacher saw that she looked good, so she agreed.

So Chu Yang and Li Zhiying collected the needs of their respective friends and set off together to play in the city.

Li Zhiying who walked in front.

There was a smile on his face.

All the time, bouncing.

Like a little white rabbit out of the cage.

Chu Yang didn't know why she was so happy.
