卡麦换流站550kV GCB设备特殊交接试验一次通过

Core Viewpoint - The successful completion of the 740kV withstand voltage test for the 550kV GCB equipment at the Kamei Converter Station marks a significant milestone in China's "West-East Power Transmission" strategy, demonstrating the capability of high-altitude power engineering [1][3]. Group 1: Project Overview - The Kamei Converter Station, located at an altitude of 3720 meters, is a critical hub for the Jinshang-Hubei ±800kV UHVDC project, facing extreme environmental challenges such as thin air and strong ultraviolet radiation [1]. - The installation team from Xi'an Xidian Electric Switchgear Co., Ltd. (West Electric) has shown exceptional professionalism and responsibility since the project's commencement on May 28 [1][2]. Group 2: Installation and Testing Process - The installation team implemented a scientifically structured installation schedule, ensuring that all insulation components were free of foreign materials and met cleanliness standards [2]. - A "new generation smart installation control platform" was utilized for digital monitoring and standardized management throughout the entire process, significantly reducing human error and enhancing efficiency and safety [2]. - A six-level dust prevention system was established to maintain a clean environment for the equipment, including mobile dust prevention shelters and real-time monitoring systems [2]. Group 3: Equipment Performance - The 550kV GCB equipment was specially designed for high-altitude conditions, featuring optimized components and intelligent mechanisms, successfully passing extreme type tests [2]. - The successful completion of the 740kV withstand voltage test not only validated the equipment's performance in extreme conditions but also confirmed its readiness for live operation [3]. Group 4: Strategic Importance - The achievement at the Kamei Converter Station represents a major technological breakthrough for West Electric in high-altitude power construction, reflecting the commitment of Chinese power builders to national strategic responsibilities [3].
