Summer social practice 丨 Changli Electric Student in -depth production and manufacturing front line

(Correspondent Tian Mengping, Li Hao Zhou Qimin) In the summer of this year, 20 college students from the School of Electrical Sciences at Changsha University of Technology went to Zhuzhou Zhongxia Electrical Technology Co., Ltd. to conduct in -depth manufacturing centers to carry out social practice activities in front of the manufacturing center. The youthful background of the rare student.

Learn professional knowledge and let scientific knowledge go to the front line of production

The manufacturing center is the company's main manufacturing department, which is divided into many different workshops such as wind power, urban rails, HVAC. In order to further give full play to the superiority of school -enterprise cooperation and education mechanism, Yang Dingding, deputy general manager of CRRC Mechanical and Electrical, gave a vivid professional knowledge lesson for practical players. "It is not enough to wear a helmet and put on a shoe cover! The workshop test needs to be connected to high pressure. There is a certain danger. It is necessary to prevent mistakes from entering the charging interval ..." On the way to the wind power production line workshop, Yang Ding Ding repeatedly emphasized the "electrical defense" to the practitioners.

After entering the workshop, he used the high -voltage power distribution cabinet as the setting point to introduce the "90 % off profess" of the power distribution cabinet fuselage beams and columns to the practitioners. It is understood that the traditional power distribution cabinet beams and columns are low and small, and they often need to be replaced and replaced. In order to solve this problem, domestic companies have developed 160 % discount profiles and twelve -fold profiles through the cold curved profiles of Germany's 10 % discount materials. "A small innovation measure can greatly improve the service life of the power distribution cabinet. There are endless practical patents like this, and we must be good at discovering problems in industrial production and break through." The combination of Yang Dingding's question and explanation not only allowed practitioners to understand the assembly process of the equipment at the moment, but also gave them a clearer understanding of the current direction of the innovation and development of the emerging wind power industry.

In order to cultivate practical players' hands -on ability, he encouraged all practitioners to operate into the switching cabinet by hand; when explaining the obscure professional knowledge, he introduced the principle with an easy -to -understand metaphor; He explained patiently. In the afternoon of the front line of the workshop, the practitioner Zhou Qi sighed sensitively: "Scientific knowledge may seem profound, but it is actually around! In the future, we must consider it carefully, actively innovate and practice, and truly combine theory with practice. The knowledge on the book is practical, and contributes its own power to the development of the country's power industry! "

Ying the mission of youth, fighting on the front line of high temperature test

In order to inspect the quality of the product, Xu Kai, the research and development engineer of CRRC, led the practical team members to cooperate with the workshop test group, workshop quality group and workshop director to conduct the heating test of the high -voltage electrical box of Tianjin No. 7 subway line. It is understood that the current used in this experiment is as high as 1400 amp and a maximum temperature of more than 100 degrees Celsius, which is a dangerous operation. The experimental content includes cable assembly, temperature sensor assembly, ambient temperature monitoring, temperature monitoring in the box, and copper -row temperature monitoring.

"The sealing measures must be done well to ensure that the test data is accurate and reliable." Before the test began, the master of the test team briefly introduced the basic requirements of the experiment to the practitioners to ensure that the test was rigorous and the data was reliable. "This large current test not only needs to ensure its own safety, but also the safety of the personnel of the whole body. Do not come into contact with the exposed wire end!" The current of 1400A was pulled up at the test site.

In order to ensure the quality of the product, Xu Kai strictly controlled the test process of the workshop test group. Practice player Mo Kangyao and Fan Xujiang were responsible for the monitoring of the product temperature curve. During the experiment, the master of the workshop found that the insulation tube was severely heated, and immediately stopped the test, and replaced the materials in time. After confirming that the safety was wrong, the test was restarted. The two members have a temperature observation every half an hour. According to the observation results, when the temperature of the box is stable, the slope curve of 0.03 degrees Celsius rises per minute. After the temperature of the three hours, the temperature of the bronze medal finally rises to 103 degrees Celsius. Saturated, and the temperature fluctuations per hour are less than 1 ° C.

With more than four hours of the test, the room temperature in the workshop has reached 31 ° C, and the high -voltage electrical box is constantly heating up. Test situation. After the collection and analysis of the data, Xu Kai said that the experiment still needs to be improved and the temperature is still higher. The practical player Mo Kangyao said with emotion: "The real process test is very different from the theoretical experiments in the school. It needs strong patience, not letting go of every detail, and always pay attention to safety. After more than four hours of high temperature, high strength After the homework, Master Xu still believes that it needs to be improved. We should learn this attitude of excellence in the product. "

In recent years, Changsha University of Science and Technology has closely arranged the fundamental tasks of Lideshu people, relying on professional advantages to actively carry out "industry -university -research" cooperation with various units. During the practice of the majority of students, the majority of students actively penetrated into the first -line grass -roots positions, learned advanced culture of enterprises, read professional books, enrich the practice scene classrooms, enhanced "eye force" and "brain power", and cultivated a large number of "bright background, strong practice, feelings, feelings, feelings, feelings, feelings, feelings, feelings, feelings, feelings, feelings. Outstanding college students who dare to take responsibility.
