Youth casting is the Hungarian Railway

Correspondent Wang Zhaojie Li Gangyu Guo Dong

"I will share with you some experiences that have passed the EU TSI certification ..." Recently, a wonderful online exchange class has attracted many employees, especially young employees of the project department of the Hungsea Railway Serbian section of China Railway International Co., Ltd. "".

What is shining is that the speaker is not the "big lady" of the technology for many years, but a "post -95s" who are new to the fledgling. His name is Liu Yaowu, from the China Railway Construction Electrification Bureau, and was adjusted to the project department of China Railway International Co., Ltd. Hungsea -Czar Railway Serbian section project department to carry out joint office. Qingxiu's face showed a stability beyond his peers.

"On the eve of the opening of the Beno section of the Hungarian Railway, under our unremitting efforts, the power energy supply subsystem, including the contact network pillar, inheritance line and other facilities, finally obtained the EU TSI certification mid -term certificate. This is other subsystem certification. It provides a reference and has accumulated valuable experiences for the successful entry of China's railway technology and equipment. "Liu Yaowu's words brought everyone back to the early stage of work.

The Hungarian Railway is the first project in China Railway electrification technology and equipment to experience the EU TSI certification. Without experience, you can learn from it. In June 2021, after selecting the best selection, Liu Yaowu became the person in charge of the TSI certification work of the power energy supply subsystem. Don't look at Liu Yaowu's project in the Hungarian Railway in 2019, but in a short period of time, he grew into a person in charge of TSI certification with a large and responsible TSI certification.

Recalling the scene when I first came into contact with the TSI certification, Liu Yaowu's face was difficult: "At that time, we did not understand the standards, and the second did not understand the authentication method, and I felt very confused." For this reason, he checked a lot of information and gradually found the direction of work. Essence

Do not accumulate, there is no thousand miles. In order to ensure the design, production, and construction meet the TSI certification specifications, Liu Yaowu actively organized a seminar to discuss with the certification agency. The origin of parameters.

In 2021, when Liu Yaowu went to Serbia CIP Design Institute to connect with professional designers in contact network, the designer Andreje said: "Liu, Serbia has not been upgraded for nearly 30 years, we have been using older standards. With both design systems, we have not performed simulation simulation, and the raising parameters proposed by certification agencies and testing agencies can only be judged based on past experience. "In order to firmly determine the designer's confidence, Liu Yaowu replied:" We Chinese often people often people. Said, there is no difficulty in the world, I am afraid of people. At present, we have found work ideas. As long as everyone works together, we can overcome difficulties. "

After the joint efforts of the builders of the two countries, the certification work continues to deepen. "The remaining residual period of the Hungarian Railway is relatively short. If the previous CH1 certification model is continued, it will face a long review cycle and affect the project on time." Another problem is in front of the technical personnel of the two countries.

In order to set a different approach, Liu Yaowu again checked the TSI certification literature. After communicating with the German certification engineer, the CB+CC mode of "on -site test+internal production design verification" is also applicable to the Hungarian Railway, and the complete re -re -re -regulations on the railway construction data In the case, the certification cycle is also relatively short.

With the on -site investigation, Liu Yaowu and Serbia CIP Design Institute sorted out the data, organizing suppliers, owners, and certification agencies to hold special meetings. CC mode.

"This can not only significantly shorten the certification cycle and ensure that the project is opened as scheduled, but also expands the certification period from 2 years to 7 years, providing strong support for the construction of the Hungarian Railway Noesu section." In the online exchange course, Liu Yaowu talked about it. When changing the advantages of the authentication method, the tone was increasingly raised, and there was no shortage of pride and pride in the tone.

In early January 2022, the personnel of the certification agency went to the construction of the Hungarian Railway construction to inspect the anti -electrical prevention protection measures. Due to the heavy snow, the personnel of the certification agency were retired and they wanted to postpone the inspection.

"Anti -electrostatic protection measures are a necessary condition for the safety opening of the project. If the inspection is delayed, it will be held and the whole body will be moved, which will affect the next module inspection, which will eventually cause the railway opening date to be postponed." Liu Yaowu recalled. He patiently convinced the other party to check normally and used accumulated professional knowledge to accurately answer the various questions raised by the certification agencies.

When the on -site inspection of the anti -electrical protection measures ended smoothly, the inspector MAX said before the Netherlands returned to the Netherlands to Liu Yaowu: "Liu, your persistence makes our trip to Serbia a very valuable trip. , I must go to ride. "

During the construction of the Hungarian Railway, there were more than 500 builders from China, of which about 70%of the "80s" and "post -90s" like Liu Yaowu. These young builders are running hard on the "Belt and Road" construction track with their youthfulness, sharpness and responsibility.
