On April 18, 2018, Shandong Electric Power Equipment Co., Ltd.'s Shandong Electric Power Equipment Co., Ltd. passed all tests at one time for the 10th converter transformer produced by the Changji Converter Station of Changji-Guixun ±1100kv UHV DC transmission project. Meet the technical agreement requirements.
So far, all 10 products of Changji-Guquan DC project Changji Converter Station have been successfully produced, becoming the first supplier of this engineering project to complete the delivery of all converter transformer products. It is Shandong Equipment Corporation following Shanghai Temple-Shandong, Zharut - After a success of 18 consecutive products, the Qingzhou DC project has created the highest voltage level in the world, the largest single product capacity, the most advanced technology level, the most difficult manufacturing process, and another world record for all successful projects. Created the world record of the success of 28 consecutive converter transformers in the world's electrical equipment manufacturing industry.
Reach the new peak of world electrical equipment technology
The Changji-Guquan ±1100 kV UHV DC transmission project is the highest voltage level in the world, with the largest transmission capacity, the longest transmission distance, and the most advanced technology in the UHV power transmission project. Shandong Equipment Co., Ltd. is responsible for the delivery of the project Changji Station 10 Taiwan-changing rheological production tasks.
The converter transformer products are single-phase, two-winding transformers with an insulation level of 750 kV on the grid side. Because of the need to meet rail transportation requirements, the biggest technical challenge for Shandong Equipment Company is that the product capacity is increased by 1 /4, but the external dimensions must be reduced to meet the requirements of railway transportation, and the product's size, key components, and insulation weight show a strong non-linear growth. It is necessary to redesign and verify the insulation system and structure, and bring design and production results. More severe tests and challenges.
In order to ensure the reliability of the project design, Shandong Equipment Co., Ltd. organized the company-level review meeting four times on the basis of the thorough understanding of the drawings, and repeated discussions on the overall design proposal and various parts and components, as well as technical differences such as design, process, and production. And key control points.
Re-exhibition of Shandong Electric's 'One Success' New Strength
Shandong Equipment Co., Ltd. successively organized and held the Changji Project Mobilization Mobilization Meeting and the Preparatory Commencement Meeting. All cadres and employees were mobilized to make persistent efforts to fight against the U.S. Changji project. On September 17, the project's products were fully started and put into operation.
In the production process of the project, the Party’s 19th National Congress was successfully held. The members of the Party Committee of the Shandong Equipment Company intensified cross-linking with the grass-roots Party branch and workshop team to publicize the spirit of the Party’s Nineteenth Congress, calling on the majority of cadres and employees to actively participate in the Changji Project, etc. Product production, with practical actions to implement Xi Jinping's new era socialism with Chinese characteristics. Party branches and various departments set up party members and commando squads to assault ahead, bravely shoulder heavy burdens, vigorously carry forward the spirit of model workers, craftsman spirit, and led a group of key employees. Committed to product production, providing strong support for high-quality production.
In the production process of the project, Shandong Equipment Company always emphasizes and maintains respect for UHV products, keeping in mind the 'one success, certain success' quality concept and 'meticulously designed, elaborately manufactured' production concept, ensuring all aspects of measures, implementation of responsibilities In place, it is completely safe. It fully solidifies and promotes the successful experience of UHV products. It insists on holding the production quality coordination meeting every morning and evening, establishing a quick and efficient communication mechanism, ensuring timely coordination and resolution of various problems, and adhering to the joint inspection of design process quality on a daily basis. Each process of the process tracking service does not miss every detail and zero-tolerance to the problem, so that the product design scheme can be fully realized. The entire production staff insists on 'fine manufacturing' and strict 'three-press' and 'three-review'. The production rhythm ensures that the production process is in place.
On December 20, 2017, the first product of the Changji project passed all factory tests at one time, and all indicators met the requirements of the technical agreement, indicating that the highest voltage grade converter transformers in the world produced by domestic manufacturers took the lead in successful production by Shandong Equipment. , was highly praised by the leaders and experts of the State Grid.
Recreating New Records in UHV Product Manufacturing Industry
A good start is half of the success. With the success of the first product, Shandong Equipment Co., Ltd. insists on steady and steady progress, and keeps pace with the orderly pace of production. It took five months until the last one on April 18, 2018. test.
The continuous and successful production of 10 Changji converter transformers once again tested the technical capabilities, scale production capabilities, process assurance capabilities, and quality control capabilities of Shandong Equipment Company's UHV products, again highlighting the serious implementation of state-owned enterprises by Shandong equipment companies. The 'six powers' requirement actively implemented the deployment of new and old kinetic energy conversions. The State Grid Corporation of China's “one six six” development strategy fully supported the responsibility and responsibility of UHV's strong smart grid and energy internet development, highlighting all the personnel of Shandong Equipment Corporation. During the critical period of ensuring the construction of UHV projects, employees have demonstrated their responsibilities. They dare to fight with confidence, fight for will and the continuous combat capability of UHV production, further consolidating and enhancing the status of the industry and brand image!
