Recently, the 11,000 kV Guquan Converter Station 1000 kV GIS on-site test conducted by Xikai Electric Co., Ltd., a subsidiary of China Xidian Group, passed all field tests, indicating that the Guquan Converter Station, the highest voltage class in the world, has taken another step toward live operation.
Xikai Electric undertakes the production and installation of a total of nine intervals of GIS for the project. With the joint efforts of all employees, the project will be completed from November 2016 to November 2017, and will complete all production within the factory. Early April of this year. , Successfully completed on-site installation. The Division insisted on building quality projects, strictly control the on-site installation quality of GIS equipment, and completed all on-site tests on May 11th.
Take special measures to control quality
In response to the characteristics of rainy and humid environment in the south of Anhui, Xikai Electric puts forward strict requirements on the installation environment of GIS equipment and strictly implements 'six dust prevention' measures. It absolutely guarantees the quality control of all GIS work processes. At the same time, the equipment itself In the on-site assembly of the bus transport unit, the mobile assembly workshop is used, and an environmental monitoring board is set up in the factory building. The measurement interval is not more than 2 hours each time. Special measures are taken in a special environment to effectively ensure quality control.
Pay attention to the details to achieve process management without dead ends
During the assembly process, the on-site installation personnel paid attention to the details, strengthened the process management, and laid a solid foundation for the successful passing of the tests. The secondary cleaning of the main busbars and branch busbars was performed outdoors, in order to ensure the installation process. Quality, on-site management and control are strictly in accordance with requirements, dustproof tents are installed, and air purifiers are installed in tents. In the SF6 gas charging process, purification and filtration devices are used on site, and a set of equipment is equipped with 2 sets of filter elements, which can simultaneously enter four Out, not only provides great convenience for inflating personnel, but also effectively improves the inflation quality.
Bold Innovation Improves Installation Efficiency
In view of the fact that the branch bus cannot be installed in a mobile plant, Xikai Electric has applied a combined environmental control system for the first time. The system includes high and low branch busbar dustproof booths, air showers and air conditioning modules, and is equipped with an air purifier. Provides a strong guarantee for the installation environment. In addition, in order to improve the installation efficiency, in addition to modular environmental control systems, Xikai Electric is also equipped with a branch bus pre-cleaning dustproof shed, which can clean up the bus units that need to be docked beforehand. After the preparation of the docking surface in the environmental control system is completed, the final docking task of the busbar unit can be performed. The combined environmental control system and the pre-cleaning of the dustproof canopy can achieve a 10,000-degree installation cleanliness of the 1000 kV GIS. Provides guarantee for the installation quality and progress of the entire project.
