Kong Wenchao, a Model Worker in Shaanxi Province: Inheritance and Persistence of the Fourth Generation Model Worker
Inheritance is the persistence of generation after generation.
Persistence is the inheritance from generation to generation.
At the vernal equinox, the plane trees on both sides of Daqing Road sprout new buds, and people coming and going have new hopes for the year.

In the coil workshop of Xi ‘an Xidian Transformer Co., Ltd., a transformer winder with a short head and a yellow helmet is working.be wholly absorbedGround winding.
His name is Kong Wenchao, a monitor of the coil workshop of Xi ‘an Xidian Transformer Co., Ltd., and he is also a "technical master" in the eyes of workers.
After 16 years of winding work, Kong Wenchao has been awarded the honorary titles of "Technical Expert of Central Enterprises", "Excellent Communist party member of Central Enterprises", "Xi ‘an May 1st Labor Medal", "Xi ‘an Craftsman" and "Xi ‘an Technical Model". In 2022, he won the honorary title of "Shaanxi Model Worker" and became the fourth "model worker" who grew up from the position of winding worker in coil workshop.
As a fourth-generation model worker in the same position, Kong Wenchao’s master is Zeng Guorong, a model worker in Shaanxi Province, Wang Wenge, a model worker in Xi ‘an, and Ding Jianguo, a model worker in Shaanxi Province. This kind of "mentoring" has also opened a new chapter in the winding work.

As a new generation of winding inheritors, Kong Wenchao told reporters: "If you want to be a model worker all day, you will definitely not be a model worker! Model workers are made, not imagined! "
"Transformer is the key equipment in the whole power system, which is directly related to people’s daily life and even national security, and the coil is like the’ heart’ of the transformer. The quality of the coil directly determines the quality, performance and service life of the whole transformer product. As a transformer winder, I must pay attention to every detail in production in my work. I am good at observing and summing up, so that I can create exquisite products. " Kong Wenchao’s quality of Excellence has made him achieve a good result of 100% passing rate of coil inspection for many years, which has been well received by users.
Kong Wenchao is constantly growing his talents, accumulating experience in research and experience, leading the team in emergencies and dangers, and refreshing the record of UHV in China and even the world again and again with his rough and exquisite hands.
In recent years, with the rapid development of the national UHV AC/DC project, the production and manufacturing of UHV AC/DC transformers have shown a trend of scale and batch, and high-end products have been started intensively, so the quality control of coil manufacturing process is more important.

In the production process of 800 kV converter transformer in the "Northern Shaanxi-Wuhan" UHVDC transmission project, the insulation of wire paper is very thin, and the insulation layer on the inner diameter side of the coil is easy to be damaged if the wire cake is tensioned at the bottom of the coil, but it is extremely difficult to find in quality inspection.
Kong Wenchao noticed this situation. Every time the wire cake was tightened in the winding process, he used a small piece of 0.5mm cardboard to guide the S-bend at the bottom of the coil and the inner diameter brace, which perfectly solved the problem of wire wear.
The workmates don’t understand his "reinventing the wheel" and there is no requirement for the craft. Why bother asking for it? Kong Wenchao said: "A small cardboard is nothing, but we all have UHV products in our hands. If something goes wrong because of the insulation damage of the conductor paper package, the reputation of the enterprise will be damaged, and the construction of national key projects will be affected. Adding cardboard to guide is just a little effort, so why not? "

In 2019, in the production of 1000KV 200 MVAR controllable shunt reactor in the "Zhangbei-Xiong ‘an" 1000 kV UHV AC power transmission and transformation project, Kong Wenchao took the initiative to undertake the winding task of the coil of the project. This product was the controllable shunt reactor with the highest voltage level and the largest capacity in the world at that time. He carried forward the spirit of artisans, worked as hard as making handicrafts, repeatedly verified and worked out the best scheme, which effectively solved the quality problem of product processing and ensured the production progress.
Technological innovation is the lifeline of enterprise’s sustainable development, and it is also the key factor to enhance enterprise’s international competitiveness. Kong Wenchao made bold innovations in combination with the actual work, and tried every means to improve production efficiency and constantly optimize the operation plan.
In the process of coil winding, the cake turning step is indispensable, and its speed directly determines the construction period of the product. With the continuous improvement of product voltage grade, the product wire size and yield strength are also constantly optimized, and the difficulty of cake turning increases. It is difficult to meet the processing needs of existing products by continuing to use the traditional cake turning method.
Kong Wenchao understands that only through technological innovation can this problem be solved. In order to improve efficiency, Kong Wenchao repeatedly studied and searched for the best scheme. Technological innovation can’t be stuck in a rut, and sometimes it can be a good idea to find another way. After a lot of verification, Kong Yan made a bold breakthrough, breaking the traditional method, changing the pad before turning the cake into the cake after turning it. In this way, it not only meets the design requirements of drawings, but also improves the efficiency by 60%, creating considerable economic benefits.

Kong Wenchao always said, "I will do a better job after receiving the baton from my predecessors!" He led the team to publish the QC results of "Improvement on the Method of Continuously Turning Cakes for Single or Multiple Conductors", which won the first prize of "Excellent Quality Management Team of National Machinery Industry" and "Excellent Quality Management Achievements of Xi ‘an" respectively, and the research and development projects of "Improving the Utilization Rate of Turning Cakes for Transposed Conductors" and "Improving the Efficiency of Drawing Lines by S-bend" all won the Excellent Achievement Award of Xi ‘an Workers’ Economic and Technological Innovation.
"When I first took the small hole, he was shy and not good at talking, but he was willing to endure hardships and worked hard. The more honor we have now, the more we should be modest and prudent, and guard against arrogance and rashness. As a model worker, he represents not only himself, but also the image of workers in the whole industry. He should play the role of’ mentoring’ and be a skilled person with comprehensive business! " Zeng Guorong, the master of Kong Wenchao, said proudly.
Since January 2020, Kong Wenchao has served as the Standing Committee of the Second Committee of the Lianhu District Youth Federation in Xi ‘an. He pays more attention to sharing his work experience and experience with young comrades, helping more young people grow into talents and injecting new vitality into industrial development.

The four generations of model workers inherited their initial intentions and relayed forward, which is a microcosm of the "Westward Change" inheriting and carrying forward the spirit of model workers, the spirit of labor and the spirit of artisans, and rallying the great strength of the workers and staff.
Report to the 20th CPC National Congress of the Communist Party of China pointed out that we should speed up the construction of national strategic talents and strive to cultivate more masters, strategic scientists, first-class scientific and technological leaders and innovative teams, young scientific and technological talents, outstanding engineers, great craftsmen and high-skilled talents.
The wheel of history runs over the long river of years, and the glory of time is hunting and screaming in the vicissitudes of life. From 1958 to 2024, "Westernization" has gone through 66 years of development, and generations of "Westernization People" have thrived on this yellow land. From starting from scratch to leading the industry, they have made arduous and persistent trekking step by step, created brilliant achievements with the solid steps of stepping on the stone and leaving a seal, and created the immortal legend of "China’s wisdom".
