I. Purpose of Practice Production practice is an important practical teaching link combining teaching with production practice. In the process of production practice, the school also aims to cultivate students' ability and methods to observe and solve problems and learn from production practice. Cultivate our spirit of unity and cooperation, and firmly establish our sense of group, that is, individual wisdom can only play its role to the maximum extent if it is integrated into the group. Through this production practice, I learned the technical management knowledge of electrical equipment operation, the manufacturing technology knowledge of electrical equipment and practical knowledge that I couldn't learn in school. In the process of learning from the workers, we have developed a fine style of hard work and plain living. In production practice, I realize that strict discipline and unified organization and coordination are the needs of modern mass production, and are also necessary for our contemporary college students, thus further improving our organizational concept. During the internship, I learned about the power supply and distribution system of the factory, especially the composition and operation process of the factory substation, which laid the foundation for the design of residential power grid and the course design of building power supply and distribution system. By visiting the automation system of Sichuan No.1 Chemical Industry Group, I broadened my horizons and knowledge, accumulated necessary perceptual knowledge for learning professional courses well, and laid a solid foundation for our future qualitative change. Through production practice, it has played an important role in consolidating and deepening our theoretical knowledge, cultivating our ability to work independently and enhancing our labor viewpoint. 2. Practice content (1) Safety education 1. The purpose of safety education and learning: 2. Accident occurrence and prevention: 1. Accident factors-human factors-unsafe behavior factors-unsafe factors II. Accident factors: 1). Management factors; 2) Violation of regulations: A. Misoperation B. Illegal operation C. Brutal operation 3) Poor safety responsibility (quality). 3. Main safety precautions when entering the factory: 1. Fire and explosion protection: 2. Dustproof and antivirus: 3. Prevention of burns and scalds: 4. Electric shock protection: 5. Mechanical injury prevention: 6. Falling from a height: 7. Vehicle injury prevention: 8. Prevention of lifting machinery injury: 9. Object hit: 10. Drinking is not allowed on duty. (2) Introduction to the characteristics of chemical production: The characteristic of chemical production is the direct catalytic synthesis of amines from natural gas. 1. Raw materials, semi-finished products and finished products are mostly flammable, explosive or toxic. 2. The production process is mostly high temperature and high pressure or kettle temperature and high pressure. 3. Strong production continuity and high degree of automation. There are many industrial wastes, which affect the environment. 3. Learn and understand the main structural types, structural types and characteristics of substations. (4) Learn and understand the production technical data of the main components of the substation, including: various technical standards, drawings, specifications of special equipment, etc. (five) to understand the main technical requirements and related standards of substation. (six) to understand the production organization and management, labor quota and cost calculation method of the factory. (seven) to understand the research situation of new materials, new processes and new technologies carried out by the factory. Four. Internship process 1. Safety Education At the beginning of the internship, the school organized us to go to the company to receive safety education from professionals, explaining the importance of safety issues and the dangers and potential dangers we will encounter in the internship. At the beginning of the internship, the school organized us to visit the internship unit in order to understand its general situation. During the internship, we also went to other related workshops for professional visits, gained more extensive knowledge of production practice and more accurately understood the operation mode of the factory. During the visit, we focused on the advanced design ideas and methods, advanced process methods, advanced tooling, advanced equipment, advanced organizational management forms and other characteristics. 3. Workshop practice Our workshop practice is the main way of production practice. We practiced in the designated workshop according to the internship plan, and successfully completed the designated internship content through observation, analysis and calculation, and consultation with workshop workers and technicians. 4. Combination of theory and practice In order to carry out workshop practice more deeply, in the process of practice, we combine the book knowledge we have learned with the requirements of practice, and the perfect combination of theory and practice also urges us to continue learning and research. 5. Internship Diary During the internship, we recorded the daily work, the results of observation and research, the collected data and charts, and the contents of the report we heard in the internship diary. Accept the teacher's examination and correction at any time. 5. Other activities While completing the internship business, we often use the opportunity of on-site study to carry out internship activities for society, workers and engineering and technical personnel. After class, we also organize parties, ball games and other activities to strengthen ideological and political education activities. Through production practice, we have learned and mastered the main structure, production technology and technological process of substation. Main tools and equipment used; Technical data of product production; Production organization and management, etc. To deepen the understanding of basic theories such as working principle, design and test of substation. Make us understand and master the working principle and structural knowledge of substation. It lays a good foundation for further studying professional courses and engaging in research and design in this field. In this production practice, we not only deepened our understanding of what we have learned, but more importantly, we corrected our outlook on labor and improved our ability to work independently.
