The frequency conversion just now only simulates the situation of the generator when the ship is bumping in the ocean and the generator is unstable. As a result, the entire stepmeter of the Yuhang Group was not able to withstand it and was burned and scrapped.

This is because in order to test power equipment such as steppers, Fenjin Factory installed protective measures in the wire circuit. Otherwise, the impact of the current just now would be enough to burn and scrap two extremely valuable generators.

Manager Huang's face looked ugly because the whole step instrument we tested just now was produced by their factory. In the past, the whole step instrument in their factory had not experienced similar tests, but this kind of imagination had never happened. But today it came this time for the first time, which made Manager Huang feel that his old face was so hot.

Jin Jingwang's face was not much better. The "puff" explosion was no different from the slap on his face, but he was more capable than Manager Huang. After all, Jin Jingwang still knew very well what their own whole step is.

"This whole stepper uses self-synchronization."

Just when Jin Jingwang and his two men felt that they couldn't hold their faces, Zhen Jia pointed to the scrapped step instrument and introduced: "This method is to increase the rotation number of the generator to be connected to close to the rated speed. Without excitation, first close the main switch of the generator, then add excitation, and use the action of the self-step torque to pull the generator into synchronization."

As he said that, Zhen Jia paused for a moment, then continued: "So the advantages of this structure are obviously easy to see, that is, it is simple to operate and quickly enter, and there is no need to add complex parallel devices."

After saying this, Zhen Jia shook his head regretfully: "It's a pity that the advantages are obvious and the disadvantages are more obvious. That is, after the generator is closed, there is a large current impact, torque impact and a deep drop in the grid voltage, especially when the power of the generator set is similar to that of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of the power of

In ordinary ship power stations, since the capacity of the generator to be merged is almost the same as that of the generator running, this type of structure is not suitable for ship use at all. To be more clear, this is a kind of technology that has long been eliminated."

Before Zhen Jia finished speaking, Manager Huang lowered his head in shame. Their factory only produces the whole step instrument, so he didn't know that what Zhen Jia said was right.

But why do they still have to cooperate with South Korea and even stop the old chopoyi with better technology? It is not that they are interested in the name of Sino-foreign joint ventures. You should know that in order to attract foreign investment these days, the country's preferential treatment for joint ventures is so great. Not only are they given considerable concessions to joint ventures in taxes, land, resources and investors, but they are also constantly building momentum for joint ventures in public opinion.

Because of this, once a certain factory becomes a joint venture, its status and wealth will be the same. Not only will it be superior to others everywhere, but it also gives these companies a lot of arbitrage room for use in the preferential policies of the country.

Therefore, in order to obtain this title, many factories do not care whether the foreign businessmen they cooperate with have the strength or not, as long as they can close it.

Manager Huang's factory obviously belongs to this situation. Do they not know what the whole step meter in Korea are like? Of course they are clear, but so what? Can joint ventures bring them greater benefits, what's the point of making the whole step meter with poor production?

What's more, if this poor whole step meter sells better and earns more, it is natural that it requires large-scale production.

Thinking of this, Manager Huang seemed to realize something, turned his head and looked at Jin Jingwang beside him, but found that Jin Jingwang didn't mean much anger at this moment. Although he was unwilling to be exposed, he was generally much calmer than him.

At this time, the stepper produced by Xiangxi Factory had already been installed between the two generators by staff. As the operator pressed the start switch, the diesel engine operated, driving the generator to generate electricity. Then the operator closed the switch, and the current was connected in parallel, and the stepper began to work.

Not long after, with the frequency conversion of various ship vibration simulations, the whole stepmeter of Xiangxi Factory still operated in an orderly manner, and no abnormalities occurred at all.

Seeing this scene, let alone an insider, even an outsider can see clearly that there is a huge gap between China and South Korea in the entire step.

In fact, this is true. Although the Xiangxi Factory is not a professional factory for producing whole-step instruments, it can be used as an instrument factory for supporting submarines, whole-step instruments are not unfamiliar with them.

So when they received the proposal from Professor Qin to provide supporting facilities for Fenjin Factory, Xue Qiang, the director of Xiangxi Factory, nodded and agreed without saying a word.

Whether the control standards of Fenjin Factory are strictly strict is put aside. As long as there is production, the production line can be maintained, the workers can be maintained, and the employees can have a full meal. Therefore, Xue Qiang didn't care about whether it was strict or not.

Back then, they were able to build the factory in the deserted mountains and hills, and they could not count the hardships and sweats they suffered during this period. Could it be that the standards of striving for the factory were even more difficult than when they built it?

Therefore, the technical quality control standards of Fenjin Factory, which are troublesome in other factories, are strictly implemented in accordance with the above requirements.

As for the product, it is a stepper designed by the Institute of Shipbuilding Machinery for a new generation of domestic destroyers in the mid-1970s. It not only has a delicate structure, but also has good versatility. What is even more valuable is its strength and durability.

It’s a pity that China’s new generation of destroyers has been on and off the horse since the late 1950s, and those in the mid-1970s did not escape this curse, which also prompted this whole step to be shelved and become a technical reserve.

This time, in order to provide supporting facilities for Fenjin Factory and to increase research funds, the Institute of Shipbuilding Machinery generously took out the design information buried in the old paper pile.

With a team that is united, unique technology, and strict control standards, if the quality of the entire step instrument in Xiangxi Factory is not good, it will be unforgivable.

This has also been unanimously recognized by the Fenjin Factory, especially Zhen Jia, who loves this worry-free and labor-saving full-step instrument.

Originally, Fenjin Factory was planning to conduct strict inspections according to the standards provided by the Japanese side, and then notify the Japanese side to adjust the purchasing intention of supporting facilities. However, before the completion of the work was completed, the Koreans couldn't wait to run over.

With such a fearless fear of death, Zhen Jia naturally didn't mind slapping her face over.

Of course, Jin Jingwang saw the huge gap between China and South Korea in the whole step, but it is no wonder that no matter how generous Europe is, it is impossible to sell you the things that are under the box, otherwise you can do it, and they really want to drink the Northwest Wind?

So what you give to South Korea is naturally an eradication technology, but even if you haven't given it all, you need to go back and explore it yourself. It would be strange if the whole step can be good.
