The heavens start from the Siheyuan electrician

Chapter 12 Can't Talk
The sun was a little weak, and the puddle at the base of the wall was covered with a thin layer of ice.

"Hu~~"

Li En blew on the hot noodles that had just been filled in the bowl, picked up chopsticks and ate a bite that filled his mouth.

"Suck and suck~~"

Holding the bowl, Li En dragged a large bowl of leftover noodles into his stomach, then breathed out comfortably, put the bowl into the pot leisurely, connected it with cold water and heated it up, picked it up and cooked it I peeled the two eggs one by one.

While peeling, open the [web page] in my mind to continue searching for professional electrical engineering knowledge, and browse and learn carefully.

[-]. Basic knowledge necessary for electricians
1. Left Zero Right Fire

2. The three-phase five-wire system uses yellow, green, red, and light blue colors to represent U, V, W, and N, respectively. The double-color protective earth wire (PE)

3. During the operation of the transformer, the current of each phase of the transformer should not exceed the rated current; the maximum unbalanced current should not exceed 25% of the rated current.After the transformer is put into operation, regular maintenance should be carried out.

4. In a system powered by the same transformer, it is not suitable to mix protective grounding and protective zero.

5. The rated voltage of the secondary coil of the voltage transformer is generally 100V.

"........."

Li En skipped the basic knowledge on the first page at a glance, and he had already memorized every content in it.

One thing I have to mention is that Li En's [webpage] is more like a treasure trove of knowledge, and the content inside is also classified into various levels.

This makes it very convenient for Li En to check.

After browsing all the way from basic knowledge to professional intermediate knowledge, Li En stopped in satisfaction and read carefully.

While watching, I ate two eggs, waited until the water was hot, and washed the pots and dishes.

Immediately afterwards, he took out a sweet potato and continued to eat while watching.

Until the sweet potatoes were also wiped out, he had read most of the [Professional Intermediate Knowledge] and cleaned up the garbage on the ground in satisfaction. Li En closed the [webpage], opened the door, and took the envelope to the post office to post the letter.

He still had to go to work, so naturally he couldn't wait for the post office to come to him in person, but fortunately, the post office was not too far from his place, so running there was justified as exercise.

Li En ran all the way to the post office, put the stamped letter into the mail box, then turned around and ran back to the yard, carrying his tool bag, drank a bowl of hot water, and went to work.

"Leaving so early."

Just two steps away, I happened to run into Xu Damao, maybe because I got a pot of chicken yesterday and earned 5 yuan, Xu Damao seemed in a good mood,
"You're early too."

Li En smiled, not wanting to have any extra involvement with him, so he didn't say a word.

"That is, for the sake of national construction, of course you have to get up earlier."

After getting a nice word from Li En, the smile on Xu Damao's face became wider, but he also knew that Li En didn't want to see people like him, so he didn't bother himself anymore.

"Squeak~"

When he was talking, he had already walked to the middle courtyard, and the door of Shazhu opened, but when he saw Li En and Xu Damao, he turned his head and closed it again.

"Hey, this silly Zhu is really a bastard. I guess I was kicked by you for committing a crime yesterday. I'm ashamed to see you now."

Seeing Silly Zhu's actions, Xu Damao let out a hey, but Li En didn't say much, just glanced at the bag in his hand: "Are you carrying a cloth bag to work?"

"No, isn't this going to deliver some noodles to the third master?"

Xu Damao chuckled, Li En kicked down the fool who beat him and played tricks, he didn't want to provoke Li En when he was free, at least on the surface.

"Oh, okay."

Li En nodded, no wonder the third master Yan Bugui was always speaking for Xu Damao in a weird way last night during the general meeting of the hospital. It turns out that this is the root cause.

He chuckled, stopped talking, and walked out of the compound directly with his tool bag on his back to go to work.

Xu Damao turned around and walked into the house of the third master Yan Bugui.

Along the smooth and clean road, Li En took big steps and soon reached the gate of the factory.

"Good morning, Master Li."

The guard standing at the door greeted Li En with a smile, and Li En also saluted with a smile: "Good morning, you too. You have worked hard since you came out to stand guard early in the morning."

"It's not hard work, it's not hard work, that's what we do. We're just on guard. What's the hard work? It's Master Li who shoulders the burden of safe operation of the whole factory. It's the real hard work."

The security guard who talked to Li En was called Lin Yuan. He was quite a real person. He had dinner with Li En before, and Li En taught him some common sense of electricity usage. what.

But in the eyes of people of this era, it is considered precious, and they even respect Li En.

"Hey, how can I say that, everyone is contributing to the development of the society, and the factory's safety shoulders are tied to everyone. As long as everyone works hard, they are all responsible for the safety of the whole factory."

Li En quickly stopped his words, feeling speechless for a while. This guy doesn't seem to be able to speak. Those who know know that you are praising me. Those who don't know think that you have a grudge against me. When it comes time to report it to the top, is that still good?
"You still can talk, I am stupid, that's good, I won't delay your work."

Lin Yuan didn't seem to realize how wrong his words were, and didn't even seem to hear Li En's warning. Instead, he smiled and waved his hand to say goodbye to him.

Li En glanced at him, turned around and left silently, but he decided in his heart that he could not get close to this guy in the future.

This kind of person may not have a bad nature, but he will definitely hurt his own people in the end, so he can't get too close.

After admonishing himself in his heart, Li En walked all the way to his work station, met with a few electricians, and then each took charge of an area, and began to routinely inspect the circuits of the factory area.

"Master, morning."

Wang Hao had been waiting at the door for a long time, and when he saw Li En coming out, he quickly greeted him. Li En nodded, and Wang Hao followed him behind his buttocks and began to check the factory circuit.

"The equipment here is a bit old, and the switch blade needs to be replaced, remember."

Arriving in front of an electric meter box, Li En glanced at the electric switch knife, and after thinking about it, it would be better to replace it. Nothing can be lost in the big factory, so he spoke to Wang Hao who was following him.

"it is good."

Wang Hao nodded his head, took out the notebook he carried with him, and began to record the location and problems that needed to be repaired.

Li En didn't stop walking, and Wang Hao also wrote while walking, until the next problematic place, and continued to record.

Immediately after a round of inspections, there was no additional place to be repaired. Li En submitted a power outage application and a component aging replacement report, waiting for approval.

"Come on, tell me about the knowledge I asked you to memorize, how much do you remember now?"

Moving the bench to the rest area to rest leisurely, Li En looked at Wang Hao and began to test his kung fu.
