Prior to this, Li Yingtao was honored to win the National May 1st Labor Medal in 2020. Li Yingtao, the new leader of Jingkou Transformer Operation and Maintenance Management of Zhenjiang Electric Power Company of State Grid, led a team of 15 people to undertake the operation and maintenance of four 220kV substations, nine 1/0kV substations,135kV substations and three energy storage power stations in the east of Zhenjiang. Power engineering load in this area is used for customers' industrial production.
Since 1990, Li Yingtao has been engaged in substation operation and maintenance, and has accumulated rich and colorful experience in substation operation and management. With the continuous innovation and upgrading of electrical equipment, he has developed step by step in continuous learning and independent innovation, and his various creative inventions and innovations have been patented. The "Li Yingtao Model Worker Innovation Studio" named after him was established on 20 15. Since then, individual studio members have actively established 10 independent innovation research groups around the key and difficult positions of the company, and obtained 4 national patent inventions, 33 national utility model patents and 4 provincial QC outstanding achievements. Under his guidance, "Li Yingtao Model Worker Innovation Studio" completed the development plan from "brighter" to "brighter" and "redder" to "redder".
"I used to create inventions by myself, and now my team works together. My key is to let a large number of young people develop behind me. " Li Yingtao said that he sent Bian Xiao to his independent innovation indoor space dust net kit, which gathered the wisdom of him and the elite team members and showed all the inventions and innovations of the elite team in recent years. Li Yingtao took out a cloud smart ring in the exhibit and put it on his helmet. "This completes the intelligent combination of lighting, shooting and communication, and concentrates a variety of special tools in a small cloud smart ring. Cloud ring is also embedded with more than N expansion sockets, which can be upgraded afterwards. The safety helmet has an expiration date, and it needs to be removed and replaced after expiration. The cloud ring design scheme greatly saves costs and gives full play to its effectiveness. " Li Yingtao gave a detailed introduction to Bian Xiao.
Maintenance trolley is a common equipment for substation maintenance. There are more than 400 high-voltage switchgear in the east, model specification 17. Due to the compatibility of traditional on-site maintenance trolleys, it is necessary to select suitable maintenance trolleys for different types and specifications of high-voltage switchgear to perform daily practical operation tasks, which will cause great confusion to the on-site actual operation. In addition, all kinds of maintenance trolleys must be customized in the power switch room, which reduces the space utilization rate of the power switch room and improves the difficulty coefficient of standardized customization of the substation.
Li Yingtao led the independent innovation working group to hold a seminar. Organize young workers to make field trips, collect data, compare and choose the best scheme, make engineering drawings, speculate on scientific research results over and over again, and even keep a low profile. After more than a year of hard scientific and technological research, they finally developed a universal maintenance car. At present, it is compatible with 17 high-voltage switchgear. In the past, there were only six or seven maintenance trolleys in each power switch room. There are more than 10 sets, and now only two or three sets are needed. The average time for a safety arrangement is reduced from 3 minutes to 1 minute, which can reduce the power outage time by at least 2 minutes. This effect has been applied to other substations, resulting in great social development and economic benefits. This achievement has won the national patent invention, the top ten technological innovation achievements of municipal employees, and the national technical achievement award for outstanding employees of electric power, energy and organic chemical geological environment system software.
During Li Yingtao's working career of 3 1 year, a rare flood caused great damage to electrical equipment. In just ten minutes, dozens of lines in the eastern power grid will jump. Li Yingtao, who has been on his way home from work, immediately transferred his car to the enterprise because of his sensitive location. In fact, Li Yingtao's discrimination is appropriate. The flood instantly caused the collapse of the 500 kV tower in the eastern power grid 1 base, and four 1 10 kV substations lost DC high-voltage power supply, causing a large-scale power outage in the planned area. On-site maintenance, staff distribution, planning ... Li Yingtao is thinking about how to arrange the steps scientifically while doing it himself. Everyone is like a motor that can't stop. It took 36 hours to repair and close a 10KV common fault line. "The maintenance left a deep impression on me. Although it is a flood, it is a great challenge for everyone. It is stipulated that everyone must have solid basic skills in order to better serve the people. " Li Yingtao said.
