Chapter 290 Hydropower Station

(Thanks to book friend 20200510022929734, book friend Mocking Crow for the reward, thank you puppet!)

The Limpopo River has three tributaries in the Bechuanaland region (now Botswana), namely the Notwane River, the Shashe River and the Nivane River.

The dam currently under construction is the Noiwane River. The dam is located 5 kilometers away from the Harbin Arsenal. When the dam is repaired in the future, the water in the reservoir can basically be stored near the Arsenal.

The hydropower station team built a dam on the river before the rainy season in October last year. The entire dam is 10 meters high, 21 meters wide and 6 meters long.

The reinforced concrete structure used in the entire dam body uses nearly 27 cubic meters of concrete.

Faced with such a huge demand for cement sand and gravel, Nanhua Company had to suspend the supply of cement in other regions and prioritize meeting the construction needs of the dam.

Because it has now entered the rainy season, the main body of the dam has been completed, and the entire reservoir has entered the water storage period. When full, the reservoir can store about 4000 million cubic meters of water.

The construction of the flood discharge channel should be earlier. When Boss Shi planned to go to the United States to find Tesla, he had already decided to build a hydropower station.

After careful inspection, Cai Jinzhang and others from the construction department finally selected the Noiwane River, a tributary of the Limpopo River, as the construction site for the first hydropower station.

The water flow of this river is not large, and there are differences between dry and rainy seasons. Construction is easy and the amount of work is not large.

Because Nanhua Company's cement and engineering capabilities were very low at that time, they first mobilized manpower and material resources to build flood discharge channels.

The entire channel is 800 meters long, 6.5 meters wide, and 3 meters deep. The installed hydrogenerator is the latest 1000-kilowatt hydrogenerator developed by the Tesla team. Three units will be installed in the early stage, and production will continue as the production catches up. Install 3 units.

(The maximum power of the Nyala Hydropower Station in 1897 was 3700 kilowatts, with a total of 10 units.)
  Now the power station has installed generating units and has entered an intense commissioning and installation period. If this test is successful, flood discharge channels will be built in the future to increase the installed capacity.

The dam will also be raised to increase water storage capacity.

In order to cooperate with the installed power generation of hydropower stations, Tesla has specially set up an AC transmission system, and the supporting voltage stabilizers and transformers have been installed in advance.

The first batch of electricity consumers was the arsenal in the southeastern suburbs of Harbin, and then came the civilian electricity in Harbin town.

In order to guide the factory to produce generators and transformers, Tesla lived directly in a nearby factory. During this time, his weight dropped significantly, but his spirit was very good.

When Shi Jintang saw him, he was also shocked, and his face was a little out of shape.

"Tesla, it's not advisable to work so hard like you. You should pay attention to rest."

Tesla smiled, and when shaking hands with Shi Jintang, he did not forget to point to the hydropower station behind him and said: "If these things don't work normally for a day, I can't rest at ease for a moment. I hope to see them working normally, so that I can sleep peacefully." go."

Shi Jintang patted this persistent man and said, "Let's go, let's talk."

Tesla nodded, "Well, I also have something to tell you."

The two of them started chatting about the radio as they walked.

"When we worked together on radio communications before, I had an idea. Since long-distance communication can be achieved, can we try remote control?"

Tesla's words reminded Shi Jintang of the original time and space that this great man really invented the remote control automated boat. This should be the earliest remote control toy.

"Well, your idea is correct, but this attempt is very energy-consuming, so should we postpone the attempt again?"

Tesla heard that Boss Shi agreed with his idea, and a smile appeared on his face, "You are right, our main focus at the moment should be on the hydropower station."

Shi Jintang smiled and shook his head, "What I'm saying is that we can try radio sound transmission first."

"Sound transmission?"

"Well, my idea is this. Radio is an electromagnetic wave. If we make the sound into an audio signal and then convert it into an electromagnetic signal, then use an instrument to receive these electromagnetic wave signals, and then restore these electromagnetic wave signals into sound.

In this way, we will realize "wireless phones" in the near future. Will it be more challenging? "

After listening to Boss Shi's trick, Tesla's eyes gleamed, "This is a great idea. Henry, you are such a genius! It's more challenging than my remote control."

Faced with the praise from the god-like man, Boss Shi was directly affected by it.

"Each other, each other, we are all geniuses!"

Tesla accepted this comment in full, "By the way, you don't seem to smoke much lately?"

Shi Jintang lowered his head and smiled bitterly, "There are too many children at home, so I can only reluctantly reduce the number of cigarettes, but I still like to have one when I am alone."

Tesla nodded, "Smoking is bad for your health. I quit it myself a long time ago. Now I walk and exercise every day, and my body is still very good. You should try your best to quit smoking." Shi Jintang was noncommittal. This matter can only be done. Gradually, he may not get used to it if he really quits.

……

In the next period of time, Tesla began to become reclusive. He asked Boss Shi to find a gramophone for him. When he was free, he would squat next to the gramophone to study and tinker.

Boss Shi still has official business to deal with. He is currently stationed in Harbin Town and can be contacted by phone if necessary.

In late March, the hydropower station finally got a call, and the first trial operation of the hydropower station was about to begin.

Boss Shi put aside his official duties and took a bus to the hydropower station.

……

When they arrived at the hydropower station, Cai Jinzhang, Lu Meng and others were already there.

Shi Jintang first greeted Tesla, then exchanged a few words with the staff of the hydropower station, and then everyone walked towards the turbine room.

Lu Meng is 20 years old this year. It is the first time he is responsible for building such a water conservancy project, and he still feels a little guilty.

However, Cai Jinzhang and other civil engineering seniors took good care of her, and helped her quickly and timely in matters she didn't understand, as well as in material coordination.

"How is your confidence in this trial run? Is it sufficient?"

Lu Meng pursed his lips and said, "Well, I still have a lot of confidence, but I don't know if I have enough confidence in these machines."

This girl dared to joke in front of Boss Shi, which showed that she was very confident.

"Well, you have such an optimistic attitude, which means that you are very sure of success this time."

Lu Meng lowered his head and stuck out his tongue, "Mr. Shi, you are so powerful, you should be able to see that my optimism is all fake. In fact, I am quite worried."

Shi Jintang looked at Cai Jinzhang, "The little girl is suing you. It must be that your construction department is not cooperating well, so she is so worried."

Cai Jinzhang shrugged and sighed.

Lu Meng was frightened by Boss Shi's actions. He waved his hands and said, "No, Minister Cai helped me a lot. It's my problem. I didn't feel confident about taking on such a major project when I first came back."

Boss Shi laughed: "I'm kidding you, none of us have experience in this matter. If there is a problem, it's because we don't have enough experience.

Just learn your lesson and keep working on it, so don’t worry! "

Lu Meng felt much relieved after being comforted by Boss Shi, "Thank you, Boss Shi!"

Shi Jintang continued to walk forward, "Let's go, open the gate and release the water."

Lu Meng looked at the handsome man surrounded by people, felt excited, and then trotted after him.

……

The turbine room is large but very empty, with a huge sluice turbine in the center of the house.

Shi Jintang stood in the middle of the crowd and announced loudly: "Open the gate!"

The three workers standing at the water gate wheel began to work together to turn the water gate wheel. As they turned the water gate wheel, they heard the roar of water hitting the cement pipe. The noise was very majestic.

The other three workers turned the waterway's gate wheel in advance. When the water passed through the waterway, they saw the three parallel waterwheels on the turbine room turning. The other five waterways did not have turbine generators installed and were temporarily closed.

As a result, the three turbine generators rotate very quickly.

Tesla and several young people on his team all stood in the hollow above the three turbines and looked down.

They are confirming the speed of the water wheel rotation and whether there is any overload.

As the water turbine rotates, soon the light bulbs throughout the hydropower station light up one after another.

At this point, everyone gathered in front of Shi Jintang cheered, and Tesla's smile became even brighter.

The first trial operation of the Notwane River Hydropower Station was considered a success!
