The speed of electricity entering life is indeed very fast. After the opening of the "Moulin Rouge", only a few days later, the library of the University of Paris was first lit up.

As a result of the lighting of the University of Paris, in addition to allowing the library to be open at night, the police also added one more thing to the police along the way: catching the thief who dug the cable.

Because of the lack of voltage transformation technology, the power loss is huge during the transmission process. In order to reduce power loss during transmission, only two methods can be used at present. The first is to build a nearby power plant.

Paris leans on the Seine River, which has plenty of water and no gaps. This is really ideal for shipping, but it is very disadvantageous for hydropower. So in Paris, it is impossible to build hydropower, and the only solution is thermal power. But in doing so, there will be a series of troubles.

The first problem is the source of coal. The coal from the Saar coal mine has to be transported to Paris. There is no suitable waterway. If it is based in the country, the solution is to first use a heavy-duty carriage to transport the coal to the Seine wharf. It was shipped to Paris; but the heavy horses in France were not enough. And it will take time to lay a track from the Saar coal mine to the Seine.

But if you take into account international trade, you can simply import coal directly from the United Kingdom, load it on a ship, and then transport it directly along the Seine to Paris. In terms of freight, it is even lower than the coal used to transport the coal at Sal . Therefore, many power stations on the French coast currently use British coal.

Taking into account the instability of relations with the United Kingdom, Napoleon also established coal warehouses in various coastal ports to store part of the coal to increase the ability to avoid danger.

Of course, one of the consequences of building a thermal power station in Paris, and more than one thermal power station, to meet the gradual increase in electricity demand throughout Paris is that it will inevitably cause serious pollution in Paris. If you don't do it well, in the future, Paris will say that it must compete with London for the title of Fog City.

In addition to building a thermal power station nearby, you can only make a fuss on the wires. Generally speaking, the thicker the cross-section of the wire, the lower the resistance. Therefore, although the power load at this time is not particularly large, the transmission cables are all very thick.

The sturdy, copper cable, and the price of copper is not low, this naturally attracts the coveting of many people. As the saying goes, "Cables have copper. Stealing is useful." Stealing cables has also become a new criminal activity. Especially for those who don’t know how to work, stealing cables is a common way to maintain their lives. Although it is not uncommon for people to be electrocuted for theft of cables, such criminal activities are still rampant. When electricity was used to pump water in rural areas, the cables had to be specially guarded. Once a foreigner appears, everyone will be vigilant and pay attention to whether it is a thief who has come to steal the cable.

In Paris, the police now have one more task, which is to prevent thieves from stealing cables. The "Moulin Rouge" is okay. There are not many poor people in the entire Montmartre area, and the place is spacious, and the power station can be arranged in a relatively suitable position downwind.

But the University of Paris is different there. The electricity there comes from the power plant that supplies the factories in Paris. These factories are located in poor areas like Saint-Antoine, where the security has not been very good. It's good to say when powering the factories, because most factories are directly next to the power station, and the cables exit the power station's fence, cross a narrow road, and enter the factory directly. The space left for thieves is really limited.

But the University of Paris is different here. The University of Paris is still a little away from the poor area, but to build a smoky power plant in the university area, both Joseph and Napoleon find it hard to bear these places. They want to go often Install 13's. Among the brothers, only Lucien and Louis felt indifferent.

So, this cable is longer, and a long section of it has to pass through the Saint-Antoine district!

The drudgery of protecting this cable was thrown directly to the Ministry of Public Security. Of course, the Ministry of Public Security receives a special grant every month, although the money is not particularly large. After receiving the money, Minister Fouché immediately ordered that according to the length of the area where the cable passes, multiplying it by a difficulty factor for public security maintenance, and then dividing the money to the local police station in proportion.

Fouché ordered: "If there is no problem with the cables in your area this month, this money is your monthly bonus. If there is a case of cable damage in your area this month, then the money will be gone. Proportionately to other police stations on this line that have no problems."

The money is not much. But this is not much for big shots. Moreover, when allocating the money to Fouché, according to custom, the government honestly considered the "fire consumption" of the money when it was operating in the Ministry of Public Security’s institutions, and Minister Fouché, he would not be too The people in charge of the "fire consumption" matter, as long as they are not excessive, they take more than the general rules. However, Minister Fouché himself did not take the "fire consumption". As a result, the small amount of money would go to the specific police station, and the result was really not small.

As a result, the small film policemen naturally mustered their strength and kept spinning along the cable from morning to night every day. And some small gangs nearby have been warned about everything: "Lao Tzu doesn't just mean you can't do this kind of thing, but as long as something goes wrong in this place, Lao Tzu loses money and is punished. You go and fight for the loss!" As a result, the criminal gangs who have to stay here for a long time have become the protectors of the cables in a sense.

Under such measures, the cable to the University of Paris has been without problems, but this is the result of concentrated efforts. If the power is to be promoted, the police department obviously cannot have such power to protect the city. All the cables inside, by then, crimes against the power system may still be difficult to contain.

"But in the long run, power transmission technology has become a bottleneck restricting us. In the future, if we want to promote electricity in the entire city, just using copper for cables, the quantity will make people feel desperate." In the analysis of the "Sleepless City" project Above, Joseph said this way.

"Fortunately, the army no longer needs copper." Napoleon exclaimed. Otherwise, the spectacle and the army compete for resources, which really makes him feel very embarrassed.

"By the way, when you told me about resistance heating last time, didn't you say that you were working on a machine that can raise the voltage? How is the progress?" Napoleon asked.

"Some progress, in fact, is going quite smoothly. However, there are still some experimental procedures to be completed. The experiment is currently being carried out in the south. You know, there are abundant water resources there, but other conditions are average and there are not too many factories. Some power stations are actually It is not running at full load. So the experiment is arranged there. An experimental transmission line has been set up. If there is no major problem, we will get the result in a few days at most..."

"Then it will take half a year to switch to industrial production, right?" Napoleon asked.

"Yeah. My brother, don't always think that as soon as you open your eyes tomorrow morning, you will see the wonders completed. Think about it, the Pyramid of Khufu, which wonder of the Pantheon does not take time?" Joseph said.

"In fact, I think the'Moulin Rouge' is already a spectacle." Lucien interrupted, "and it's still a spectacle that can give us continuous money. It can increase smiles and increase gold coins. It's perfect... …"

At the same time, in the south, that new experimental transmission line is also under construction. The workers erected a particularly high electric pole on the ground at intervals, and hung a string of things like ceramic bowls on it. Now that the electric poles have been installed, workers are now under the guidance of engineers and technicians to hang new electric wires on the electric poles.

Compared with the common arm-thick cables, this wire is much thinner, not even thicker than the thumb. In addition, this kind of wire is also very special. The middle of this wire is a steel wire, and the surrounding is a copper wire. There is also a very strange place ~lightnovelpub.net~ that is, this kind of wire is completely bare wire without insulation material.

Unlike ordinary cables, these wires cannot be directly mounted on the poles, but should be hung under the string of "porcelain bowls". Each electric pole has a string of "porcelain bowls" hung on the left and right, and then a wire directly exposed to the air is hung under the string of "porcelain bowls".

The wire stretched to a strange machine nearby, and then two thick cables with insulation were separated from there. There is no plastic in this era, so the insulation of wires is generally of composite structure. The innermost part that is in direct contact with the metal is a layer of asbestos. This kind of thing will be banned in most countries because of its strong carcinogenicity in later generations, but at this time, no one cares about it.

On the outside of the asbestos, there is a thick layer of oiled paper, and the outside is a layer of asphalt.

In charge of the test task here is Joseph's student Andre Ampere. At this time he is making the final preparations before the experiment.

He checked the condition of the transformer. The iron core and coil, as well as the cooling oil soaked in them, are in good condition. He checked the other equipment carefully, and then said to the people around him: "Well, let's start the experiment now..."
