During the week of April 13-17, a total of four workshops in the Wubian arena held PK competitions, including two specifications of high-voltage winding in the dry transformer workshop, JP-100 secondary assembly in the box transformer workshop, 50,000/110 final assembly in the third workshop, and two amorphous low-voltage foil windings in the distribution transformer workshop. In the course of the competition, each workshop recorded in detail the content of the competition, and then used the replay and data application to add additional workload in the middle of the dry and distribution changes. From the point of view of competition efficiency, the high-voltage winding of the dry transformer and the secondary winding of the box transformer workshop have achieved good results, and the efficiency has been improved) 24.8% and 25.4%. In order to allow the reference workshop to perform PK better in the future, draw on the previous experience and lessons from various aspects and apply them, the dry-transformation workshop, box-transformation workshop and third workshop exchange and share the game replay, they closely focus on PK master planning Requirements, and carried out this work carefully and meticulously, individual workshops have also made innovations on this basis, further enriching the content of the rewinding, and setting an example for the PK post-winding of other workshops and departments in the future, and achieving good results.
On April 19, our company Zhang Yong, Zhu Binfeng and Wu Hua went to Wuhan to take charge of the installation of Phoenix Mountain 500kV project.
On April 16, after the installation of six 334000/500kV main transformers in Chuzhou Tongle Substation of Anhui Province provided by our company, all tests were passed at once, which provided a strong guarantee for the resumption and production of Anhui Power Grid. Anhui Chuzhou Tongle 500kV substation is the key transmission and transformation project in Anhui Province this year. It is to enhance the power supply capacity of the Chuzhou region and strengthen the grid structure to meet the needs of the regional economic development. The project will be Chuzhou after completion. The important substation of the power grid is the main power point of the 220kV power grid in Chuzhou and other counties and cities. It plays an important role in improving the power supply capacity and reliability of the power grid in Chuzhou and ensuring the safe and stable operation of the power grid. It is beneficial to expand the coverage of 500kV , Which created favorable conditions for the future operation of Chuzhou 220kV power grid. The following May, Tongle station will officially send electricity, and then our technical experts and service personnel will also be on site to contribute to the transformation of Wuwang!
On April 10th and 11th, three skill PK competitions were held in the first line of the JP cabinet of the company's box substation workshop, the 10kV brace curtain in the fourth workshop, and the welding of 110kV clamps in the first workshop. Mr. Shen visited the box-transformer workshop and deployed the process and material preparation for the installation of the box. It requires everyone to arrange the process reasonably, use resources reasonably, improve efficiency, and improve quality. On April 10th, the box-transformation workshop took the lead in carrying out a JP-100 installation PK competition, which took the form of seven single-person combinations, each with 12 sets of tasks. This workload was time-consuming according to previous statistics and requires 18 It takes hours to complete, that is, it takes more than two days of work. This time, it is a big challenge to arrange the game to be completed at one time. In order to make this competition a complete success, the workshop did a lot of preparation work in advance, such as the production of copper bars, the prefabrication of connecting wires, the unpacking of various electrical components, the inventory of quantities, and the quality inspection. After the hard work of seven employees, the fastest was completed at 9:00 in the evening and the slowest ended at 11:00 in the evening. The efficiency has been greatly improved in the past. In the two games conducted on April 11, the content of the four workshops was to paste the insulation group SBH15-M-200/10 bracing curtains in a single group of 4 groups, each with a task of 20 units. According to the past production efficiency, only 10 workloads can be pasted per person and one shift. In this PK, workshop leaders and the production department made more careful planning and arrangements to make the preparation of various materials for the competition adequate. In accordance with the requirements of the PK master plan, the workshop conducted process training and assessment for the participating employees, so that everyone can fully understand the basic knowledge and manufacturing process of insulation parts, so that they can completely achieve strict "three-press production" in operation. The 110kV clip welding competition in the first workshop is the company's first self-competition, that is, the PK between its current efficiency and its past efficiency. The production of large clips has been in short supply for a long time, which has affected the next iron core lamination process. At the same time, the workshop produces it by itself. Due to the low efficiency, high cost, and lack of market competitiveness, the production department has been so troubled by this, often I need to find a supplier that meets the requirements of our company. I once wanted to remove this process. A full set of clips are prepared for outsourcing and personnel are diverted. However, the employees of Wubian Company have a spirit of unsuccessful defeat. The workshop director actively asked the superiors to retain this process. On the premise that the leaders of the production department and the workshop reached consensus, the two parties made careful planning and organization. After the self-PK competition, the efficiency of the participating employees improved significantly, and the efficiency of a single unit increased by 29%. Next, the company will also hold a variety of skill competitions. Through these competitions, I hope that the workshop will carefully review the experience and lessons, sum up certain rules, improve the efficiency and quality of work, and continue in the future work Work hard to achieve Wu's goal of becoming a leader in the power transmission and transformation industry.
