Chapter 1308 The Song of Electricity ([-])

"It was not until 1844 that there was the first industrial DC generator, which was specially used for electroplating. It was not until 1873 that the generator and the motor were connected in series. Before that, the generator generated electricity and stored it in the battery. Then drive the motor. As for the excitation method from permanent magnet to current self-excitation, it was a paper written by Siemens in 1867. The modern armature, that is, the drum shape, was designed by Adenik of Siemens in 1872. The compensation winding of the motor And laminated iron cores did not appear until 1885. And the general three-phase synchronous power generation mode did not appear until 1887."

The popularization of Faraday's "multimedia" demonstration aroused everyone's interest.Although most of you here know these fragments of knowledge, few people understand them so comprehensively.

"What I said so much is that we don't need to go through the original technology tree again. For example, the motor we successfully trial-produced was manufactured according to the drawings we brought, which is the Y in the original national standard of time and space. series three-phase squirrel-cage asynchronous motors, this series of motors can basically meet the requirements of most of our current workshops for prime movers - you must know that a 10T electric crane needs only a 15kw motor."

Then he began to talk about the types, functions and principles of power equipment, and then he talked about the general principles of power transmission and distribution.Basically, it is taught in a simple way: the veterans present are all engaged in science and engineering, and they can understand it without too many details.

"... Then again, everyone has a misunderstanding that everything related to electricity should be managed by the power port. In fact, the power industry, as the name suggests, is the same as the machinery industry. It is the machinery industry that produces machinery, and the electricity industry. It is the electric power industry, that is, the power station is ours, but the generator is not ours. In fact, the generator is a category of the machinery industry. Let me say a few words here. Our machinery industry is addicted to silly big black It is an irresistible trend in the rough steampunk culture. We have more than 100 veterans in the villages and towns of the mechanical factories who use themselves as fitters all day long. What the hell is this? I think the production chain has matured. In the world, the veterans must be liberated and invested in other places that need veterans. We have an electric motor that doesn’t work every day. If you want to find a mechanical veteran to help you roll your eyes, I’m not him. Mom earns the family property for herself, and I do it for everyone's future and tomorrow..."

"Cough, cough, cough." Qian Liushi heard that something was wrong and hurriedly coughed to signal a warning. Faraday said to Qian Liushi, "Well, if you talk too much, you will hurt your feelings. The Executive Committee and the Planning Institute have approved it. : Set up a project team for the production and development of electric equipment, and Qian Liushi and I will take the lead for the time being. I hope that more professional mechanical colleagues will participate in this project team, make our electric equipment bigger and better, and cross the border as soon as possible. Enter the age of electrification."

"Okay, Faraday's introduction is here first, let me continue with everyone." Qian Liushi was afraid that Faraday would make another mistake, so he quickly cut the topic, "Actually, the Planning Institute has long wanted to use our current factories. The prime mover was changed from the original steam engine to an electric motor, but because silicon steel and various insulating and sealing materials have not been started, these plans are only lip service.”

"Now we have to do this. First look at the demand, and then see what we can provide. At present, there are only a few requirements for electricity. If there are gaps, you can fill in. The most important job at present is to meet the necessary electricity consumption of various industrial enterprises. Projects: electrolysis and electroplating. Especially electrolysis consumes a lot of electricity and has a great impact on the non-ferrous metal industry and the chemical industry. We will start to solve this demand first.”

After this science popularization, the meeting was generally formalized. After discussions, the veterans of the industry made a general plan on the manufacture of electric equipment and the direction of electric power development.

The first is to manufacture silicon steel.At the current level of steel plants, only hot-rolled silicon steel sheets can be produced.Then, by continuously testing the hysteresis curves of various fineness silicon steels, a rough grade can be obtained for use in motors and transformers.

With a stable and reliable supply of silicon steel, build a professional motor workshop: in addition to the production of Y series motors, low-speed air-cooled permanent magnet generators below 100KW can be mass-produced-this can be done without brushes.This kind of generator can be driven by a steam engine, if there is a diesel engine in the future, it can also be driven by a diesel engine, or even a small hydropower station can be driven by a water turbine.Machine terminal electricity 400V.The insulation problem of this low-voltage motor is more than enough with mica sheet and mica paper.This series of generators is relatively light and can be used in combat logistics centers, headquarters or construction sites.The combination of generators and electric motors will greatly improve efficiency compared with steam engines - of course, the premise is that Lingao's industrial system can provide diesel engines and the required fuel on a large scale, otherwise the advantages of using gas power will be compromised.

As for power transmission and distribution, the unanimous opinion of the veterans of the mechanical and chemical industries is that there are too many technical difficulties to be overcome, and there are also many missing links in the industry.At present, in addition to being able to barely produce all kinds of make-shift wires and cables, transformers, circuit breakers, etc. are difficult to produce. As for electrical secondary such as ammeters, voltmeters, etc., there are difficulties, which may be difficult to overcome in a short time.Therefore, it is recommended to mainly use self-provided power stations for capacity expansion.Set up self-provided power plants in chemical and smelting enterprises that require a large amount of electricity.A large number of low-speed air-cooled permanent magnet generators are driven by a steam engine to generate electricity, and electricity is used locally.

The electric power work conference "has come to a successful conclusion". After the meeting, Chang Kaishen hosted a banquet in the farm tea house for Liu Tom, Faraday, Qian Liushi and other "key technicians" and toasted them for their "hard work and perseverance" , Zhong Lishi was also invited to a banquet.In the past few years, Faraday and others have been able to make some achievements, and Dr. Zhong's silent support as the People's Committee of Science and Technology is indispensable.Otherwise, Faraday would probably have jumped ship to a steel factory to do materials science.

Dr. Zhong seldom participated in the entertainment among the elders on weekdays, but this time he graciously accepted the invitation.Minister Chang knew that Dr. Zhong would not refuse as long as there was a good meal.So he generously swayed his circulation coupons.Prepared a lot of "advanced" dishes for banquets on weekdays.

Although the tea house is for veterans, the level of the chef is not that of a red chef.Wu Nanhai has no intention of using the teahouse as a restaurant, so the Guihuamin chefs trained by the teahouse are good at dim sum, desserts and light meals.When a banquet is really needed, a chef is called in from the commercial restaurant to take charge of the cooking.

The chefs in the Shangguan restaurant are all trained by a few veteran "foodies" who can eat and cook. Among them, the recipe of Nanbao roast duck was taught by Zhong Lishi himself.He is good at making all kinds of dishes, which is quite in line with the palate of the elders.

The banquet is set by the window of the podium of the teahouse facing the water - the height of the building is low, and the weather is already warm and the flowers are blooming before March, the long windows are open, and the smoky wind is blowing.

On the table are dishes with local characteristics of Lingao: four hot dishes: braised spicy ox-eye snails, steamed creamy crab, smooth-roasted sandworm, dried radish with belly meat; two big dishes of salt and pepper pork trotters, roasted Nanbao duck, Vegetables are stir-fried Duowen water spinach with mashed garlic and boiled scallions; served with two dim sum dishes: fried shrimp and leek cake with oil paste and Lingao fried pile.

The wine is rice beer and Leizhou rum made by the farm cooperative. Naturally, kvass, the "national drink", is indispensable.

Even in 1633, when the living standards of the elders had been greatly improved, this banquet was still considered "luxury", especially the rotten skin crispy meat, slightly medicinal pig's trotters and small pieces of pork belly, which made all the guests present Several swallowed their saliva secretly.

The host and several people exchanged cups and cups, and ate and drank very happily.During the banquet, Chang Kaishen toasted frequently, and soon the faces of several people were drunk.

Dr. Zhong was already a little bit drunk, and felt that he couldn't drink any more, so he talked about the issue of academic journals.

"You guys are working on electric motors this time, which is very good!" Zhong Lishi said, "Record the test data this time, and later everyone will summarize all the parts they are responsible for, and put them together to issue a core."

Dr. Zhong's so-called "core" is the first academic journal of this time and space: "Nature and Science" organized by the Ministry of Science and Technology and issued by the Great Library.Zhong Lishi of the Ministry of Science and Technology is the editor-in-chief of this journal, and the editors and reviewers are the people with the highest professional level in various departments of mechanometallurgy, chemistry, electrical materials, precision instruments, and biology.The periodicals are basically the latest work achievements and production results of various industrial departments, focusing on the exploration and practice of "copying" and "reproducing" modern industry by the elders under the existing conditions.

The issue of Nature and Science magazine has to a certain extent replaced the technology edition in the internal forum in the past.With the deepening of the first five-year plan, the work of each department was gradually separated, and everyone was busy working during the day and doing work at night, and it gradually became deserted.

Many veterans are no strangers to publishing core periodicals before D. Although it is annoying to write papers, due to the adoption of an active remuneration system-especially the auction of Yanmars, everyone pays more and more attention to circulation coupons.Therefore, contributions are still enthusiastic.This magazine is distributed once a month to every veteran for free.As a supplement to the information, it is also good for various professionals to keep abreast of the work of other departments in order to apply the latest technological development as soon as possible.In addition to the handbook of Yuan Laoren, a part is also printed and provided to large libraries, schools, and professional reference rooms of various enterprises for reading by naturalized people's scientific and technological personnel.For this reason, it is clearly stated in the manuscript that words such as "old time and space" should not appear in the paper, and it is not allowed to mention the history of old science and technology.
