Recently, two sets of 750MVA/500kV on-site assembled transformers of the 500 kV substation in Qiongjiang (Qamdo) substation of the Hanjiang and Qamdo power grid interconnection project - Qiongjiang 500kV substation expansion project, all passed the test project with on-site acceptance conditions. The groundbreaking progress was made in the assembly of transformers on the site at the time of installation. This has laid a solid foundation for ensuring that the Tibetan-China network project will be commissioned on schedule.
Tibet Tibet and Zhongdu Power Grid Networking Project is the world's highest altitude, the largest span, and the most complex natural power grid project. Baoshen Electric undertakes the assembly and assembly tasks of two 750MVA/500kV field assembled transformers for the expansion of the 500kV substation of the Minjiang River. Taiwan is a 'party member'. In the process of product manufacturing, Party organizations at various levels of Baobian Electric actively organized party members' commando teams, party members' project research activities, and comprehensively served production. Party members actively participated in the manufacture of 'party members' transformers. In November 2017, the production and manufacture of the 'Party' transformer was completed.
Since the 'Party Member' transformer arrived at the installation site, Baobian Electric formed a field assembly commando with party members' technology, production and management backbone as the core, and solidly completed every link. Design, process, assembly and other units are closely Cooperate, speed up the construction of the plant, reconfigure the tooling and tools required for the assembly work and urge it to be sent to the site to ensure that the on-site assembly work starts on schedule.
The on-site assembly of UHV transformers is the biggest highlight in the construction of the Tibet-China and Changdu grid interconnection projects. It can solve the transportation problems caused by the overweight and oversized large-capacity main transformers. The 500-kilovolt substation of the Minjiang (Changdu), with an altitude of 3,200 meters, air The oxygen content is only 70% of the plain. It is the 500 kV substation with the highest altitude and the hardest working environment in the world. The region is located in the 'Sanjiang' fault zone with the most complex geological structure and the widest geological disasters in the world. Change, one mountain has four seasons, ten different days, the effective period of the year is only six months. In this regard, the Baobian Electric Party Committee attaches great importance to the mobilization of technical experts, has prepared a scientific and reasonable special construction plan, pay close attention to implementation, pay attention to details, Strictly ensure construction safety and quality.
The Tibet-China network main transformer assembly site is located on the plateau, the climate is abnormal, and the air oxygen content is low. The commando players who first arrived at the plateau are very uncomfortable, and have various altitude sickness such as headache, rapid heartbeat, insomnia, and difficulty in breathing, but no one has fallen. On-site assembly work. Receive transformers in place, inserts, assembly, oil treatment, accessory installation, etc., and they complete each link with high standards.
Before the transformer was installed, Baoding Electric developed a targeted assembly plan for the dangers caused by the severe coldness of the plateau, which greatly improved the work efficiency while ensuring the safety of the operators and equipment. To ensure on-site assembly of the products. Progress, the commando team strives for perfection, strictly controls the construction period nodes and quality key points. The problems are promptly reported, and everyone negotiates and solves them. Every day except for half an hour of eating, the rest of the time is all on the product installation, ensuring that the transformer is 'one-time. 'Assembled in place.
From the end of 2017, the 'Party' product was delivered to the site for on-site assembly, and recently passed the on-site assembly test. The self-defense spirit of Baobian Electric staff fully demonstrated the image of Baoding Electric, and was awarded the State Grid Leadership, State Grid Supervisor and The height of the construction unit is praised.
