2972: C2972 Land Model

C2972 Land Model

Even if you're on a jet, when you get to the city of 7712, it was already afternoon, and it was currently the rainy season. The sky was constantly drizzling. In the rain, Twelve landed easily on the runway of the airport. Then, the bus that had been waiting there for a long time brought along a group of people. They went straight to the research institute.

At this time, Professor Ma had already boarded the bus. After not seeing him for a few years, he seemed even more mature. He was originally a young man, so he was entrusted with a heavy responsibility. However, he did not let down Qin Guan's heavy responsibility. Now... He was incomparably excited when he heard that Qin Guan was going to come here for an inspection. He quickly went to the airport to welcome him.

This way, Professor Ma could begin introducing them on the bus.

"Right now, the western side is developing a medium voltage communication system. After repeated comparisons, we believe that our medium voltage system is one generation ahead of theirs." Professor Ma began to explain the specific technology.

Electricity propulsion, although not applicable on warships, but in other occasions, there were already finished products... For example, a mine car, a giant mine car, a wheel that was as tall as several people... Obviously, it can't be driven directly by the drive shaft. To the car's converters, it was a disaster. These cars... That's right. The form of power, the power that the engine used to power, the power that came out... And then it's supplied to the electric motor on the wheel, driving the wheel to turn.

These are all used for medium-voltage communication.

The medium voltage was the medium voltage. If one were to be specific, this voltage was between 3000 volts to 10 thousand volts. Compared to the commonly used supermarket electricity, it was 220 volts. It seemed to be very high, but in fact, it was still considered Medium voltage. Because if it was high voltage, it would be above 10,000 volts. It could easily be hundreds of thousands of volts.

Makarov had specially prepared a translator for him. He translated these words almost at the same time. Makarov nodded his head when he heard it. That's right. There was a lot of advantages in the middle pressure compared to the middle pressure.

First of all, it was the conjoined power generation problem. It was the current communication and power transmission system. A parallel power transmission was a difficult problem. One needed to have a synchronous frequency to be able to do it. Otherwise, they might cancel each other out and waste the power on the transmission line. The consequence was that it would immediately burn down.

For the power grid, this was not a big problem. Anyway, as long as it was adjusted once, it would not be needed in the future. However, for warships, frequent activation was a big problem for parallel power generators.

When it was low speed, using one generator was enough. To increase the speed, to turn on more equipment, more generators had to be used. When the second one was activated, it had to be connected to the net. It was quite cumbersome.

For direct power, it was not necessary. Anyway, it was a matter of positive and negative. As long as the docking was in place, it would be fine.

"At the same time, the direct current does not produce an infectious resistance, so the transmission efficiency is higher" After Professor Ma said that, he said to Qin Guan, "President Qin, the path you pointed out is completely correct. We believe that we are one level ahead of the medium pressure exchange technology. "

Right now, Han Country was in the lead in all aspects of high technology. Naturally, it was the same in terms of the warship's power system.

"President Qin, the plan you chose?" Makarov looked at Qin Guan in surprise. Qin Guan was an all-rounder. He had a unique understanding of all kinds of techniques. He might not know the specific details. However, in this general situation... There would definitely not be any mistakes in his direction.

"Yeah, this thing will be very beneficial when it's developed. Our domestic high-voltage power transmission technology will also be developed in the future." Qin Guan said with a smile.

Since there was long-distance power transmission, communication and power transmission were the mainstream. After all, it was very easy to use a transformer to lift and lower the voltage. But... The efficiency of the transmission was not high, so Han Country would also need to conduct a continuous supply of electricity in the future. Furthermore, in this aspect, it had an outstanding advantage. Now, it was time to prepare the technology.

As they sighed, in the drizzling rain, they entered the 7712 units and went straight to a large factory.

"This is the model we are building." Professor Ma introduced the model to everyone.

It could be seen that there were two diesel engines for ships here. As for the power output, it shouldn't be too high. After all, this directly determined the cost.

Behind the diesel generators for ships, there was a specialized direct current generator. Then, it was connected to the electric motor at the back through the transmission line. The motor was not connected to the propeller. Instead, it was connected to the testing equipment, forming a complete circuit.

"There are two diesel engines used here, each of them can have five thousand horsepower" Professor Ma looked at the huge engine and gave a detailed introduction: "The generators that are following behind, each one has four megawatts of watt, and then drive the generator behind"

This kind of power system can drive around ten thousand tons of cargo ships. Of course, if it was a warship, it would probably only be a 1,000 ton frigate. After all, warships needed a very high speed.

"Our system is mainly used to verify reliability" Professor Ma continued: "Now, let's demonstrate it for everyone"

The ship's diesel engine starts very slowly, after all, it doesn't use an electric generator. Instead, it used compressed air to pump the compressed air into the tank of the ship's diesel engine. It drove the diesel engine to spin, and the speed of the diesel engine was also very low. Usually, it was only a few hundred revolutions. It had a different flavor.

Now, following the sound of compressed air, the diesel on the left started to spin in a low voice. Black smoke came out, followed by the diesel on the right. If one looked closely, the model of the two diesel engines was different. Because these were found on some outdated ships. It was really not easy to be able to operate stably.

Following the operation of the two engines, the various instruments on the side of the platform were displayed. At the same time, there was also a specialized computer that was outputting all kinds of data.

"Now, let's look at the power curve." Professor Ma pointed out the display on the screen. Although everyone might not understand, at this moment, the curve was constantly climbing.

"Now, an engine is providing power. When we need more power, we will connect the second generator."

As he spoke, he operated the computer a few times. It seemed that he was very familiar with it. The curve suddenly jumped up a lot.

The comprehensive power system needed to be able to automatically and smartly allocate power to the places needed. So, if there were only mechanical devices, it would be unqualified. The key was the power allocation.0

"Next, let's simulate it. The No. 2 Motor suddenly malfunctioned." Professor Ma said and continued to operate the interface.
