Hand rubbing nuclear fusion live in the wilderness

Chapter 142
After counting the losses, Han Yuan looked at the two motors on the ground and could only sigh.

For him, running was purely instinctive.

He used to use a hair dryer in the dormitory when he was in college, and the electricity leaked and caught fire, and the person who was hit by the electricity almost lost his life.

He has always had a psychological shadow when facing things like electricity.

When working on generators and electric motors these days, he was always wary.

So after seeing the motor short-circuited and caught fire, his first reaction was not to cut off the power supply, but to run away first.

Although this move caused him to lose two motors, Won did not regret it very much.

Leave the green hills without worrying about no firewood.

If it is burned, it will be burned, and the people are still there. If there is no problem, it can be rebuilt.

What's more, not all of them were burned.

Although the loss of the motor was relatively miserable, many parts inside were melted into a ball.

But the generator is okay, most of the parts inside can still be used, but parts such as enameled wires and brushes need to be redone.

In the two disassembled motors, the damaged parts were cleaned out, and the remaining intact parts were put aside for later use.

Picking up the parts of the motor, Han Yuan carefully inspected each one, trying to see what went wrong and caused the motor to burn when it reversed.

The motor he made is a two-phase motor. From a structural point of view, it only needs to change the position of the zero and live wires, and the high-speed magnetic field generated inside can rotate in reverse.

This is also the principle that the motor can rotate in reverse.

Since there was no problem when it was turned frontally for the first time, it is certain that there should be no problem with the parts inside.

Something went wrong with the parts and it shorted out the first time it was turned on.

Even if the parts are fine, Han Yuan turned his attention to enameled wires, brushes and electric rings.

These three materials are the most vulnerable to damage and leakage short circuits.

It is a pity that these three materials were burned badly due to short circuit, and the insulating varnish on them had been burned off, so it was impossible to tell which part had the problem first.

However, from the degree of melting, with the help of the knowledge and information in his mind, Han Yuan still managed to distinguish some details.

Compared with the enameled wires on the stator and rotor, the most melted ones are the brushes and electric rings.

The enameled wire just burned off the insulating paint on it, but the two parts, the brush and the electric ring, can be said to have been melted and completely deformed.

After studying these two parts, Han Yuan pinched the damaged brush and electric ring and said to the camera: "The problem should be on the parts in my hand."

"These two parts are the key to connecting the external power supply to the core of the generator to generate a rotating magnetic field, and they are also the most easily damaged parts."

"It should be that there is something wrong with the installation or something went wrong, which caused the motor to short-circuit and catch fire."

"As for the specific reasons, because these two parts have been almost completely damaged and cannot be traced back, so we can only judge these."

"Except for the loss of two motors, the problem is not very big, but we should pay more attention next time."

[I feel distressed for the anchor, I really have nothing left. 】

[It's a normal thing, just pay attention next time. 】

[I was electrocuted when I was a child, 220v household electricity, I was foaming at the mouth, and I didn't recover for a long time. 】

[Actually, when the motor catches fire, pulling the electric valve is the first thing the anchor should do instead of running. 】

[If the power is cut off immediately, not to mention the generator, most of the parts of the motor should be preserved, but it’s good that people are fine. 】

[According to incomplete statistics, the number of people who die from electric shock in our country exceeds five figures every year. 】

Looking at the barrage, Han Yuan shook his head and didn't say much. This time he did make an incorrect demonstration.

In the event of a short circuit, fire, etc., the first thing to do is to turn off the electric valve to avoid greater losses.

It took two days for Han Yuan to re-create the generator and motor.

With the experience of the first time, and a large number of parts still available, the second time is much easier.

After learning the lesson from the last time, the motor made again has been able to rotate forward and reverse smoothly and stably after several experiments.

After remanufacturing generators, motors, and light bulbs, Won put the manufacture of thermometers on the agenda.

For this purpose, he prepared a large pot and an oversized wooden barrel.

Then, under the watchful eyes of tens of thousands of people in the live broadcast room, he held his nose and dismantled the convenient toilet.

[Fuck, anchor, what do you want to do? 】

【Looking for shit? 】

[Didn't it mean to make a thermometer?What are you doing dismantling the toilet? 】

[Hey, it's disgusting, I'm going to slip away first. 】

[A certain anchor is looking for (shit) live broadcast, with a monthly income of one million. 】

[Gan!Labor and capital are eating, caught off guard. 】

[Ruthless person, the original latrine, the smell can be imagined, and the anchor can't change his face. 】

[Fuck, anchor, you don't really want to try the taste of this thing, do you?I have no objection, but remember to let us know after you try it. 】

[Eating shit, you! 】

Looking at the messy barrage, Han Yuan was speechless.

"What are you all thinking about?"

"I'm looking for nitrate!"

[Nitrate?what? 】

[Nitrate, sulfur, charcoal, the three basic pieces of black powder, you don't want to make explosives, anchor, do you?I advise you to be kind. 】

[Upstairs, I advise you to be kind! 】

[If you are looking for nitrate, look for nitrate, why are you dismantling the toilet? 】

While tearing apart the earthen wall of the toilet, Han Yuan explained: "There are things like nitrate in the toilet besides the natural nitrate mine."

"Because human and animal feces and urine contain a lot of potassium nitrate salts."

"If you are a friend who has lived in the countryside since childhood, you should know that in winter, a layer of white fluffy crystals sometimes grow outside the earthen wall of the toilet."

"That's nitrate."

"But I'm in the tropics now, and the nitrate in the toilet can't condense into crystals, so I can only purify the nitrate by refining the nitrate used to make the toilet."

After a pause, Han Yuan continued, "The reason why I refine nitrate is not to make black powder."

"Instead it's used to create ice cubes and then define the temperature."

【So, you want to cook shit? 】

[No need to explain, if you want to eat, just eat. 】

[Can nitrate be used to make ice? 】

【Anchor, if you are really hungry, you can secretly eat something we don’t know about by yourself at night. Now it’s fine, and the whole world knows that you like it. 】

Looking at the barrage that was still teasing and complaining, Han Yuan's face was darkened.

Ignoring the sand sculpture audience, he quickly cut off a layer of soil outside the earth wall while pinching his nose.

The soil in the outer layer contains a large amount of nitrate, which is equivalent to natural nitrate ore and is an excellent ore for refining nitrate.

It's just that the smell is really bad.

But no way.

He did not find any nitrate ore, and electric ice making is not realistic for him at present.

So it can only be made in this way.
