Hand rubbing nuclear fusion live in the wilderness

Chapter 161 Transformers and Regulators

On the bullet screen, there was confusion.

In fact, most of the audience did not understand Won's explanation.

After all, half of them have never gone to college, or even high school. Even if they have gone to high school and college, almost all the knowledge in their minds has been returned to the teacher when they graduate.

Han Yuan couldn't do anything about these confusing bullet screens.

It's not bad for him to be able to talk about these things once. If it weren't for the fact that he was already used to communicating with the audience, he wouldn't talk about it.

Forced, it is refreshing to pretend to be seen by people who know how to do it.

There's no point in pretending to be real in front of a group of people who don't know how to do it.

The coil in his hand was still winding, and after a while, the iron core in the transformer, which looked like the word "Lv", was covered with long and thin copper wires.

The iron core with the coil wound is the core component of the transformer.

All that's left is to assemble it.

The iron core is placed in the transformer casing, and then fixed with screws to prevent movement.

Switches, tap changers, oil pressure valves, thermometers, and radiators are all installed in sequence.

It didn't take long for a transformer, which was the size of a black and white TV when I was a child, to show its appearance.

Now it is only necessary to pour the shed oil into the core at the core, that is, the insulating oil.

Seal the top of the transformer, tighten it with bolts, and insert the funnel made of plastic into the oil inlet.

The fractionated shed oil was as thick as honey, and slowly flowed from the container into the funnel, and then into the transformer, filling the core.

The enclosed transformer is like a big iron lump with two antennas on it. It looks ugly, but it doesn't prevent it from working normally.

After the transformer is manufactured, there are still some coils and other parts left on the ground.

This made the audience in the live broadcast room very confused, asking whether it was missing or wrong.

After all, judging from the previous live broadcast, every time Won assembles tools and electrical appliances, the pre-manufactured parts are fixed.

Except for the core parts and vulnerable parts such as bearings, they are basically just right, and there will be no more or less.

[Anchor anchor, you missed something, there are still cable sets and parts on the ground. 】

[What's with the pile of parts on the ground? 】

[Is it a leak? 】

[Is it used to make the second transformer? 】

[If this is missing, it will be ridiculous. When the transformer is powered on, it will burn out immediately, which is a big accident. 】

【Last time, the anchor burned the motor and generator, and almost got an electric shock. The latter are all newly made. 】

[I used to secretly disassemble the TV at home. When I put it back in, I found that there were still screws and parts that were not installed properly, and it burned. I dare not tell my parents until now. 】

[Speaking of dismantling things, everyone should have done it before. Who would dare to say that they have never dismantled things? 】

[Curiosity is the reason for human progress. 】

[Isn't it because of laziness? (dog head)]

Seeing that the bullet screens deviate from the track as usual, Han Yuan has long been used to it. When there are too many people, he can say anything.

"It's impossible to miss a part if you miss a part."

"The transformer has been manufactured. These parts on the ground are not used to make transformers, but to make voltage stabilizers."

As he spoke, he got up and took out the blueprints on the table beside him, flipped out a few blueprints from the middle, and showed them under the camera.

The ultra-clear picture allowed the audience in the live broadcast room to immediately see the text marked on the first drawing.

【Stabilizer? 】

[Is there any difference from a transformer? 】

[Looking at the name, it should be used to stabilize the voltage, right?But doesn't the transformer also have this function? 】

[I don’t understand again, ε=(ο｀*))) Alas. 】

[Is there a scholar coming out to explain? 】

The bullet screen was full of doubts, Han Yuan put away the drawings and smiled, and said: "A transformer is a transformer, and a voltage regulator is a voltage regulator."

"Although the two have the same name, there are still some differences."

"Everyone knows that there are coil components in devices such as motors and transformers."

"And these coil assemblies create eddy currents that impede current flow during the early stages of energization."

"The eddy current will not only weaken the instantaneous voltage when the electrical appliance is started, resulting in slow start, but also strengthen the instantaneous voltage generated after the circuit is broken, which may cause sparks to damage the circuit."

"Old audiences should remember that I had an accident when I was building electric motors."

"I didn't judge the specific reason at the time, but I thought about it carefully later."

"It is very likely that after the motor is running, the core rotor generates a magnetic field and eddy current, and when I replace the zero live wire and run the motor in reverse, the eddy current inside has not subsided."

"In this way, the new eddy current generated by the reverse rotation will conflict with the original remaining eddy current, causing the voltage inside to explode instantly, and then burn the parts inside."

"So when I tested again later, I waited for some time for the vortex to subside before starting."

"And now, because the transformer contains a large amount of insulating oil, although the insulating oil is insulating and non-conductive, it will burn."

"So in order to avoid the excessive eddy current generated by the wire group inside the transformer after the power is turned on, causing the temperature inside to rise to the ignition point of the insulating oil, I need to control the stability of the current."

"Then creating a voltage regulator is a must."

According to the drawings, Han Yuan assembled the voltage regulator.

A crude voltage regulator is simpler than a transformer.

"Complete coils, coils, small motors, lift switches, switches, casings."

Just a few parts are enough to make a simple voltage regulator.

At present, the Korean won does not need transformers and voltage regulators to look good.

As long as they work properly and stably.

Beautiful things are estimated to be far away from him.

For him, when labor is no longer in short supply, when is it possible to consider whether the appearance looks good.

The simple voltage regulator is also very simple to manufacture. After the completion, it is just a tin box with two wiring ports exposed.

Manufactured voltage stabilizers and transformers are transported to preset locations, then connected with copper wires, and incorporated into the circuit.

After the transformer and voltage stabilizer were connected, Won was connected to the hydraulic transmission shaft and started debugging.

The generator works quickly, and the generated current passes through the voltage stabilizer first, and then enters the transformer.

The transformer is controlled by disassembling the switch to adjust the number of coil groups and further adjust the voltage.

The transformer he made has three sets of coils inside, and each set of coils corresponds to a different voltage.

Although he is currently unable to judge the voltage strength by the standards of human equipment, this does not prevent him from making a voltmeter.

This thing is also the law of electromagnetic induction, just like a generator.

It's just that the material of some wire groups is not copper wire, but other materials with stronger resistance.

This thing, he made it a long time ago.

Moreover, the current intensity from the second generator was also measured, and the voltage was about 120 volts.

However, this voltage standard is defined by the South Korean won itself. As for how many volts it is converted into the standard of human society, I don’t know.

Because he didn't define it at all.

However, South Korea roughly judged that this voltage is much stronger than Huaguo's 120 volts.

The reason is the brightness of the bulb.

The brightness of the bamboo charcoal filament increases with the intensity of the voltage, the higher the voltage, the brighter the lamp will be.

Judging from the brightness of the lamp when the generator was used for the first time, the intensity of the voltage far exceeded 220 volts.

It's just that after the accident with the motor in the back, Han Yuan adjusted the structure of the generator.

Adjusted the speed of the gear and reduced the number of coils inside, and cut down the voltage intensity of a large wave.

After all, he doesn't need too high voltage now, and when the high voltage is unstable, it is easier to burn out electrical appliances, and it is more dangerous.

When the decomposition switch fell into the first group alone, the reading on the voltmeter had risen to about 170.

This means that the strength of the voltage has increased by about 55 volts after a round of wire groups.

The boost isn't huge, but relatively speaking, it's enough.

After all, there are two sets of coils behind.

After three sets of tests, in the end this small transformer can pull down the original 120 volts to a maximum of 380 volts.

This number, even by Huaguo's standards, is enough for most of the factory equipment.

What's more, the one on his side is even higher.

And more importantly, after installing the transformer and voltage stabilizer, the intensity of the current has obviously stabilized.

When testing with a voltmeter, the pointer hardly jumped.

This indicates an unusually constant level of amperage coming from the transformer.

In the future, you will never have to worry about burning out the lamp due to the fluctuation of the current intensity.

The transformer and voltage regulator were connected to the circuit and started to work, and Han Yuan also showed a satisfied smile on his face.

Putting away the voltmeter in his hand and putting it on the table, he was ready to download and go back to sleep.

After a busy day, I can finally take a break.

After saying hello to the audience in the live broadcast room, Han Yuan turned off the live broadcast and left the hydraulic studio.

It has to be said that with more and more equipment, the hydraulic workshop is almost full.

Previously, two-axis machine tools, generators, motors, lamps, wooden tables and other equipment were placed inside, and now transformers and voltage regulators have been added.

The space that used to feel not too small, now looks a little crowded.

Looks like it's time to remodel or rebuild the hydraulic workshop.

At least the two-axis machine tool is ready to move out.

After thinking about it, Han Yuan decided to repair an electrical workshop in the past two days, and then transfer the electrical equipment there.

After all, all kinds of electrical equipment are placed in the hydraulic workshop now, which feels a bit inaccurate.

Anyway, now that the appropriate plastic has been manufactured, the copper wire is wrapped with several layers, and there will be no leakage.

It can be used as a suitable wire.

In addition, the electrical wires of the chemical laboratory and the wires leading to the wooden house also need to be arranged and remodeled.

Back at the wooden house, Han Yuan washed his face, then sat in the workshop with the lights reflecting and recorded the process of manufacturing transformers and voltage stabilizers today and some information he learned.

It has become a habit of him to record the work content of the day every night.

Even if it is not an electrical device but something else, the won will record it on paper with a pen.

It is worth mentioning that, in order to make records more convenient, he also transformed and manufactured a brand new pen.

"Charcoal pen."

Selected hardwoods are fired into charcoal, then crushed and ground into powder, and then some selected clay and vegetable glue are added to make a black refill.

Finally, use a lathe to get out the pen holder, then press it together, wait for it to dry, and then use it.

Although it is still not as good as a pencil, it is much better than writing with bamboo and feathers dipped in charcoal water before.

It is already quite good for drawing and recording text.

In the simulation space, Han Yuan is recording the information of transformers and voltage regulators, but he doesn't know that a wave is happening in reality.

In reality, Huaguo, the capital.

A special operations team that has been established for only two days is busy in the brightly lit building.

On the table are various pictures in the KRW live broadcast room.

On the four walls, there are live broadcasts of Korean won in different periods, and the live broadcasts on each wall are different.

Some are Won's early wilderness survival videos, and some are recently made by Won's generators and motors.

In the huge room, dozens of staff were constantly busy inside, and the atmosphere was tense, but it seemed extraordinarily silent and silent.

Almost no one spoke, and sometimes they just exchanged a few words and passed information to each other.

And just next door to this room, there are also some people who are busy.

But this room is much more lively.

On the solid wood office chair, a young man just hung up the phone, then leaned back, pinched the bridge of his nose with his hands, and seemed to have a headache.

"Xiao Li, how is it? Is there any good news from Douyu?"

Seeing this, a middle-aged man about 46 and seven years old who was sorting out information on the other side asked.

"Good news shit."

The young man sitting on the chair sighed, and couldn't help but swear.

"The person who took over the server from Douyu just got the news that the technicians couldn't even delete the previous live video recordings of this anchor."

"The data stored in the Douyu server has been deleted, but as long as you click on this live broadcast room, the live broadcast history is still there."

"More importantly, you can download it at will, even if you are a Douyu user, alas."

Hearing this, the middle-aged man couldn't help but frowned, then thought for three seconds, and said:

"What about tourists? Can tourists download it?"

"Tourists are not allowed, only registered users are allowed." Xiao Li replied.

The middle-aged man nodded, and continued: "Then, notify Douyu to stop the registration of new users immediately."

"Let's talk to the people at the Internet Security Bureau again, and let them keep an eye on this anchor on the Internet for [-] hours, and report any news at any time."

Xiao Li on the office chair nodded, and after making a phone call, he hesitated and said, "Boss, don't we really want to clean up the relevant materials and information on the Internet?"

The middle-aged man shook his head and said, "I won't clean it up for the time being. We haven't contacted this anchor yet. I don't know what the other party's purpose is, and whether he has the ability to threaten the earth and China."

"However, we still need to control the development of the situation, and don't repeat the incident of direct messages flying all over the sky last time."

".."

And the scene that happened in Huaguo was just a microcosm.

There is no complete secrecy in the world. On the back of Huaguo, the same scene also appeared in another powerful country.

Research on the Korean won is also going on.
