Abstract
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.
