The biography is very fleshy, but the reality is very skinny. Faraday claimed to be a direct descendant of the Three Kingdoms Wing Marquis Fa Xiaozhi and Fazheng. His father named him this "sugar daddy" in order to regain his legal family status. However, this name not only made him grow up There was no other effect than being looked at in surprise - he had joined the pirate ship because he was over 30 years old and still guarding a substation in the outskirts of a third-tier city, with no possibility of upgrading or changing the guard at all. Sex - D-Day gives him a door that can hopefully restore the glory of his ancestors.
Faraday began researching electric machines in 1630. Since he did not receive project approval from the Planning Institute, it could only be regarded as his "private research" - this kind of private research is carried out by almost every senator. After the new time and space, it seems that everyone wants to do it for themselves. Establish a monument and pass on the legacy, leaving something to spread your honorary name to future generations.
However, the so-called private research means that you cannot obtain the right to use controlled materials and professional equipment allocated by the Planning Institute - of course this is nothing to the veterans who conduct research in literature, history, philosophy or purely theoretical fields. There are big books Library information is enough. But it's very difficult for the rest of the veterans who need to conduct a lot of experiments, which means they can only use non-controlled materials. If you didn't bring tools and equipment with you in your luggage, it would be very difficult to use some equipment and tools: not only do you have to risk your life to borrow them, but you also have to find the right time - there is almost no factory that does not operate 24 hours a day. of.
When Faraday was doing research, not only did he not have silicon steel sheets, he couldn't even get the most basic copper wires, enameled wires, and mica papers. Therefore, he could only do paper research, calculate formulas and modify drawings, and then make several models out of wood. Later, Dr. Zhong from the Ministry of Science and Technology learned of his embarrassment. Setting up a "motor pre-research" project for him was enough to stop Faraday from talking about it on paper.
Faraday used the materials obtained from the Ministry of Science and Technology to make several simple electric motor models - roughly the kind he made by winding coils in middle school physics experiments, purely for feeling. He also used the computing center of the Ministry of Science and Technology to simulate his design. Only after he had a certain degree of confidence did he start designing and manufacturing his first experimental motor.
The reason why the electric motor is chosen as the breakthrough point is mainly because the electric motor has the lowest difficulty in ending the entire power system. Electric motors are much simpler than generators, and rolling copper windings is not difficult. There is no need for a complicated cooling system, just use simple air cooling, and the casing can be cast. Lingao's current ability is more than enough.
The most important thing on the motor, besides the copper windings of the stator, is the soft magnetic material on the rotor. This is an unavoidable obstacle. In the old time and space, these things were made of silicon steel sheets. Although anyone who has done some research on electricity knows that in theory, cast iron or cast steel can achieve the purpose without using silicon steel sheets. But after many experiments and calculations by him. I found that the gap between the theory and reality of this thing is too big. He specially asked veterans in materials, structure and machinery to perform calculations. The conclusion drawn is that if alternative materials are used, there will be a huge gap in size between the motor produced with the same power and the motor brought from the drawings from the old time and space.
But everyone has no experience in redesigning motors, and they don’t have the will to go all out to do something big. The elders’ mode of climbing the technology tree is roughly a mixture of the Eighth Route Army military industry and Warhammer 40k. On the one hand, they strive to find products that meet the low-tech level. On the other hand, the original design of the old time and space will never be changed whenever possible - especially the overall design blueprint. The Senate actually does not have much ability in technological innovation and can only copy as much as possible.
After many unsuccessful experiments, Faraday It is believed that instead of spending a lot of energy to circumvent the problem of silicon steel, it is better to choose to break the material problem of silicon steel. Otherwise, the subsequent problems caused by using cast iron and cast steel materials will be more complicated.
Although it is quite difficult to smelt silicon steel, the Senate has established a fairly high-level steel industry after all. It is still possible to smelt silicon steel using this industrial system.
Although it is said that only hot-forged silicon steel can be produced based on existing equipment and technology. There is a slight difference in parameters between this silicon steel and the cold-forged silicon steel in the old time, but this is much better than the difference in order of magnitude between cast iron and cast steel.
That is to say, but Faraday's authority does not yet allow him to request steel plants to trial-produce silicon steel. He can only make a proposal on this issue at the Planning Institute meeting through Dr. Zhong from the Ministry of Science and Technology, and it will be included in the "project establishment" of the Planning Institute. Say it again.
Faraday couldn't wait for the Ma Niao Steel Consortium to provide him with silicon steel sheets. He made a report through the Ministry of Science and Technology and obtained several kilograms of silicon steel sheets in stock from the Planning Institute for trial production.
After reading a lot of information, Faraday believed that with their current technical level and material science capabilities, there was no need to start from the lowest level of motors, but to directly launch mature motors from the old time and space. These motors have ready-made drawings and process manuals that can be used.
However, the trial production of motors was not something he could do alone, so he brought in another sixty-six dollars to join the team. The two of them discussed it and decided to use the Y-series three-phase squirrel cage asynchronous motor in the original space-time national standard - this kind of motor. The technology is mature and widely used, and there are a lot of reference materials available. And judging from the experience of more than 30 years in the original space, this kind of motor can stand the test. Once the trial production is successful and passes technical verification, electric motors between 0.75 and 37kw can be mass-produced.
In order to trial-produce this electric motor, he asked several veterans in machinery and materials for help. We are busy using the workshops and equipment of the Science and Technology Department. Finally, in the autumn of 1632, the first Y-series three-phase squirrel cage asynchronous motor manufactured in this time and space was successfully trial-produced. Named "Guangming Unit No. 1". Of course, "Guangming Machine No. 1" cannot be said to be truly "manufactured by Lingao". Not only does its silicon steel come from another time and space, but even the copper wire used for winding is made of electrolytic copper wire brought from the old time and space. All the copper they smelt in this time and space is fire-processed copper, which is not suitable for use as winding material for motors.
However, this achievement has verified that the power department is fully capable of making its own motors, which gives the power department a lot of confidence. Minister Chang Kaishen said meaningfully when approving Faraday's application for materials and funds: "The motor testing task is tight!"
On the other hand, the main generals Faraday and Qian Liushi did not have such great confidence. They know that as long as the steel company cannot produce silicon steel, all their achievements will be nothing but clouds in the sky. The silicon steel sheets required for this series of motors they plan to mass-produce range from a few kilograms to a large one to about a hundred kilograms. It is impossible to rely on the reserves of the Planning Institute for so much silicon steel. It must be based on self-produced silicon steel.
Everyone knows that the performance of self-produced silicon steel cannot be compared with the silicon steel of the old time and space stocked by the Planning Institute, but they don't know how much the difference is. Besides, thermal gadolinium silicon steel sheets were mainly used as generators in the old time and space.
This electric power conference was held under the leadership of the Planning Institute. Many people in the electric power sector hope to coordinate and resolve these technical issues one by one at the meeting.
Looking at the noisy and murmuring conference room, Faraday's eyes fell on Qian Liushi, who was sitting not far away. This partner is also the "technical backbone" of the power company. He was originally engaged in generator construction and installation, and he is considered the person who knows the most about generators in the power department. He is a person who has seen pigs running and eaten pork. He was a go-getter in the installation and construction of Baiji Hydropower Station, but that was all. Both of them are "ambitious" figures in the power department - but they don't admit it themselves.
Qian Liushi came to time travel just because his brain went crazy. Previously, he worked in the international engineering department of a power generation equipment company for two years on the construction and installation plan of power stations. Due to the international financial crisis, the capital chain of his project was broken and the contract was suspended. He had nothing to do at that time, so he started browsing forums, and found out that he was very interested in the topic of time travel. Later, he took advantage of a business trip to come to the training camp, and then he was distracted and never went back. After resigning, it was too late to recover, and the only way to go was in the dark.
Fortunately, he thought this was a good choice. Since he joined the time-travel organization relatively late, everything was basically ready when he arrived, and he had already spent all his wealth to serve naked, without even a certificate of surrender. Suggestions on purchasing a variety of water turbines, steam turbines, boilers, gas turbines and various types of generators were also rejected because any one machine would cost millions. Fortunately, he had previously obtained a large number of manufacturing drawings of various power generation equipment and electric facilities, which gave him a little confidence to buy a ticket. It's a pity that the smallest capacity generator set in his drawing is 5,000 kW, and the next smallest is 35,000 kW, and now Chuanzhonglian does not have the ability to manufacture 500 kW generators. Let him always have time to master the skills of slaying dragons.
As the hour hand gradually pointed to 1 o'clock, Chang Kaishen, the Energy People's Committee entrusted by the Planning Institute to preside over the meeting, took the floor. Chang Yuan is only in his thirties, but his hair is already a bit bald. He speaks slowly and with a slight Zhejiang accent.
"Comrades, I, entrusted by the Wu De Yard of the Planning Institute, am here to preside over this electric power work meeting today. I hope that everyone can speak freely at the meeting and make their own contribution to the electrification of the Senate! In this new year, let We work hard for a new life and a new job!"
