摘要

2024年2月26日，我国首台±550千伏直流气体绝缘开关设备（GIS）通过了180天户外长期带电测试，这是我国±550千伏直流GIS首次通过带电测试。该项目由西安交通大学、西安西电开关电器有限责任公司、中国南方电网有限责任公司共同研发。该项目由西安交通大学、西安西电开关电器有限公司和中国南方电网科学研究院有限公司联合开发。该项目由西安交通大学、西安西电开关电器有限公司和中国南方电网科学研究院有限公司联合开发。由于没有产品标准，也没有同类产品的运行性能，项目组参考国内外相关文献，设计了一套科学的验证方案。试验过程中，一半以上时间的工作电压达到额定电压的 1.2 倍，同时施加 5000 A 的直流电流，以模拟实际工作条件。试验在露天环境下进行（图 1），期间产品经历了暴晒、暴雨、沙尘、高温、大雪等恶劣天气，经受了最严格的考核。

Stories From China

On February 26, 2024, China's first ±550-kV direct current (DC) gas-insulated switchgear (GIS) passed the 180-day outdoor long-term electrification test, which belongs to the first pass of the electrification test for the ±550-kV DC GIS in China. The project was codeveloped by Xi'an Jiaotong University, Xi'an XD Switchgear Electric Co. Ltd., and China Southern Power Grid Scientific Research Institute Co. Ltd. Because no product standard nor operational performance of similar products exists, the project team designed a scientific verification scheme by referring to relevant domestic and foreign literature. During the test, the operating voltage reached 1.2 times the rated voltage for more than half of the time while applying a DC current of 5,000 A, so as to simulate the real-working conditions. The test was conducted in open air (Figure 1), during which the product was exposed to the sun, rainstorms, sand dust, high temperatures, heavy snow, and other severe weather, undergoing the most rigorous assessment.

期刊介绍： The EI Magazine publishes articles written by authors from industry, research institutes and academia. The articles are more practical in content than the papers published in the Transactions. Usually three articles are published in each issue. The articles deal with dielectric materials, processes and new developments applied to industry products. Also the EI Magazine is used to promote upcoming conferences and solicits papers for the conferences. In addition, reports on past conferences are given in many issues. Book reviews and news items are included. An editorial is written by both the EIC and the President of DEIS in alternate issues. Advertising of insulation products appears in many issues.
