Building infrastructure in the wizard world

Chapter 260 The Power Problem

The sun is still high in the sky, the word hot, Shi Hao has already said that he is tired, and even his body has slowly developed a bit of habit.

With Lei Chao leading everyone in the Phoenix King's spirit world, Shi Hao wasn't too worried.

Now, there is one thing that worries Shi Hao even more.

"The weather is getting hotter and hotter, and everyone's demand for water is getting bigger and bigger." Mu Zhou, the head of the cooking team, reported to Shi Haohui.

"The cost of water in the past two days is at least twice as much as before. With the opening of the breeding center in Yangcun and the breeding farm in Zhucun, the demand for water may increase in the future." Hanchi said. The manager of the water has also been devastated these two days.

The water consumption of each garden is gradually increasing, and it is impossible for Blast Wind House not to give it to Shen Fu She.If water is needed in Yang Village, there must be a lot of water in Kongjia Village.The Wooden Garden consumes a lot of water for new plants, and the Golden Garden is even more in demand for iron-making water.

If it is given here, it is impossible not to give it there.

This side is for survival, and the other side is for development, both of which are the capital to settle down.

Adding up all these items, Hanchi's side is already stretched.

"Water is not a problem. The groundwater in our underground is sufficient, let alone more than 1 people and elves, even tens of millions of people can use it." Shi Hao assured Hanchi.He has already confirmed this point with his spiritual power and unknown totem.

"But how to get the water up is a problem!" Han Chi expressed.

This is the problem involving electricity.

This is also a question that Shi Hao has been thinking about.

Since there was a problem, the first thing Shi Hao thought of was the Academy.

Soon, Kong Wenhua and Kong Wenxue received Shi Hao's call for help, and they rushed to the plane tree with Kong Yao, Kong Lin, Kong Wu and Kong Li.

After all, Shi Hao is not omnipotent. As a zoologist, the problem of electricity obviously touched his blind spot in knowledge.

After hearing Shi Hao's question.

"The problem with electricity? If electricity is not enough, then generate electricity. What's so difficult about it?" Kong Wu asked rhetorically.As an extremely optimistic and contagious teacher, Kong Wu's way of thinking about problems is very simple: no - do it.There is a problem - solve the problem.It's that simple!
"How can it be that simple? It's all that simple, it's fine." Han Chi's confidence in Kong Wu is different, and he is more faced with reality.

Kong Wenhua and Kong Wenxue looked at each other. They both knew that it was time for the Kong family to take action.

"Then let's take a look at the cause and effect of the matter first." Kong Wenhua took the lead and said.

"We don't have electricity now, so we have to organize the establishment of a power plant. There is no objection to this?" Kong Li asked rhetorically.

Han Chi shook his head, of course he had no objection.

"Then, in a power plant, the most critical equipment is the generator, which directly generates electricity. You are familiar with Kong Yao, can you tell me about it?" Kong Wenhua clicked on Kong Yao's name.

"In the scope of my research, there is no problem. When it comes to generators, we must be clear about the law of electromagnetic induction. That is, a conductor placed in a changing magnetic flux will generate an electromotive force. If the closed conductor is in a changing magnetic field, or the closed conductor is in the Cutting motion in the magnetic field will generate current in the conductor.

This is the basic principle of generator work.

Taking the current generator in our camp as an example, the power generation process is as follows.

It is like using fuel oil to burn the water in the boiler into high-pressure steam, and then the steam drives the steam turbine to rotate.After mechanical conversion into circular motion, the rotor of the generator is driven to rotate.

I tried to understand the structure of our generator.There is a stator inside, which is composed of iron core, frame, coil, etc., and is mainly used to generate a fixed magnetic field.

The rotor in the generator is mainly composed of rotor windings, magnetically permeable iron cores, rotor shaft extensions, guard rings, center rings and fans. When it rotates, it cuts the magnetic field generated by the stator and generates electromotive force.

Since the electromotive force is generated on the rotor, it is necessary to use three slip rings to draw out the three-phase alternating current and distribute it.The generator of this power generation method is called a pivot generator, which generates electric energy from the moving rotor end, so the power cannot be made very large.We have a generator like this.

As for the working mode of our other generators, it is pole-rotating type.

The structure of the rotating pole type is to install the coil winding with the same number of turns of the three-phase coil on the stator, and install the magnetic pole and the excitation winding on the rotor, and use two slip rings to feed the DC excitation current to the rotor excitation winding to generate a constant current on the rotor. magnetic field.

When the rotor rotates, the magnetic field also rotates. The rotating magnetic field passes through the three-phase symmetrical winding of the stator, which is equivalent to cutting the magnetic field of the three-phase winding of the stator. Therefore, the three-phase symmetrical potential is induced in the three-phase winding of the stator. After connecting the closed loop, it is Output three-phase alternating current.

In this way, since the electric energy is generated from the fixed stator end, there are no moving parts, so the power generation can be made very large. "Kong Key finished speaking one-fifth and one-tenth.

Confusion was written on the faces of the people present.

"Listen~ I don't understand." Hanchi felt the suppression of his IQ. He knew every word Kong Yao said, but when he connected it, he was at a loss for a while.

"If you don't understand, come to the academy to listen more." Kong Lin said.His time is also very busy, he doesn't have time to talk nonsense with students here.

Shi Hao who was about to speak: ...

???

"This, this is indeed a bit esoteric. Haha~haha." Shi Hao said with a half-smile.The implication is: I didn't understand either.

"You don't even understand?" Kong Lin opened his mouth, and after he finished speaking, he realized that it was Shi Hao who asked the question, and felt a little regretful.

But in order to return to the academy to study faster, Kong Lin spoke.

"To put it simply, we now have several roadbeds for building power plants: thermal power plants, hydroelectric power plants, wind power plants, human power plants, elf power plants, plant power plants, and even nuclear power plants.

The principle of these power plants is that the entire power generation process is actually the process of converting various energies into electrical energy.

For example, a thermal power station burns fuel to convert its chemical energy into heat energy, then heats the water in the boiler into steam, drives the steam turbine to do work, converts heat energy into mechanical energy, and finally converts the mechanical energy into electrical energy through the generator set, thus completing the whole process. power generation process.

Therefore, firepower, waterpower, windpower, manpower, spirit power, and nuclear power plants are similar in terms of technological process. "

Kong Lin explained the matter clearly and simply.

Now, it depends on how Shi Hao chooses, as long as Shi Hao points out a way, they will do it.

The eyes of everyone present, and all the pressure, returned to Shi Hao.
