On the eighth day of September in the twenty-sixth year of Chongzhen, Li Zhi squatted on the ground of Beihu Machine Tool Factory and looked at the two instruments for measuring power conditions.
This instrument is the latest product of the Electric Power Laboratory.
One is for measuring current. The principle is very simple. It is to coil the insulated wire to be measured on the iron core to form a coil, so that the coil forms a certain magnetic force and drives an iron pointer next to it to rotate. The passing current is more
Stronger, the stronger the electromagnetic field formed, the greater the pointer will deviate from the zero scale, indicating the current intensity of the current on the scale.
The other is for measuring voltage, which uses the principle of electromagnetic induction to form a small current loop next to the main wire. The stronger the voltage in the main wire, the relatively stronger the voltage in the small current loop, and the stronger the current formed. In the small
By making a pointer meter for measuring current on the current loop, you can measure the voltage of the main wire.
Now Li Zhi has written all the physics knowledge he has mastered into textbooks and taught them at Fanjiazhuang University. Of course, this physics knowledge also includes electrical knowledge. Basically, the level of electricity at Fanjiazhuang University is at the level of freshman and sophomores majoring in electricity in later generations.
, making such an instrument is naturally a piece of cake.
Li Zhi looked carefully at the pointer on the meter and found that the current was very stable at this time.
Li Zhi looked at Chen Yiming, an electrical expert standing aside, and asked, "Professor Chen, why is the current here so much more stable than that of Fanjiazhuang Thermal Power Station?"
Chen Yiming cupped his hands and replied: "Returning to the prince, the electricity here is generated by the hydropower station. We control the speed of the water at the hydropower station. The water turbine in the water inlet is almost rotating at a constant speed. Driven by such a water turbine, the current generated is naturally
Very stable.”
Li Zhi nodded.
Hydropower stations are a good thing. Compared with thermal power stations that use steam engines to convert heat into potential energy, the output power and current of hydropower stations are very stable. You must know that Li Zhi today does not have the ability to stabilize current. If he wants to obtain electric energy with stable output power,
The only way to do this is from the power generation equipment.
Hydropower stations are a good solution to this problem.
Li Zhi stood up, looked at Cai Huaishui, and asked, "How is the actual effect?"
Cai Huaishui raised his hands and said, "Your Majesty, using this stable current machine tool, the accuracy is much better than before."
As the general manager of the Fanjiazhuang state-owned factory, Cai Huaishui has spent his spare time over the years learning various basic knowledge from Fanjiazhuang University. Now he has mastered more engineering knowledge than just burning glass. He also has a profound understanding of electricity and machinery.
know.
In this era, Cai Huaishui can be said to be at the top of natural science.
However, with the talent training of Fanjiazhuang University, there are more and more people like Cai Huaishui whose knowledge level far exceeds the times. After these technical talents arrive at their posts and are tempered by practice, they can often quickly become the business backbone of their industry.
.
These business backbones are the reason for the rapid development of Fanjiazhuang's scientific and technological level.
If Fanjiazhuang ten years ago relied on Li Zhi to continuously come up with new inventions, now Fanjiazhuang is a group of engineers working together to continuously climb the peak of science and technology.
"oh?"
Li Zhi became happy after hearing Cai Huaishui's words.
The accuracy of machine tools is a key indicator that directly affects the scientific level of a country.
However, improvements in electric machine tools have now made it possible to produce this new type of equipment.
Cai Huaishui raised his hand and said: "As long as the prince draws the design drawing, I will immediately organize the craftsmen to carry out research."
