要約(英語): This paper is the fourth report of gas-insulated switchgear (GIS) history (basically after 2000s to present) in Japan from a view point of transitions of the technological developments and practical applications. Firstly, technical progress of 550 kV GIS especially focused on from 1990s to 2010s was summarized referring to an application example of 550 kV mixed technology switchgear (MTS). Application of MTS to 550 kV GIS made it possible to reduce the weight of equipment and SF6 gas. An example of refurbishment of aged 550 kV switchgear to the latest one was also presented. Secondly, deterioration phenomena and their issues for aged GIS were studied regarding gaskets and contacts (e.g. contact wear and grease). Also, a replacement example of aged GCB by using the latest MTS was introduced as one of life extension methods for aged GIS. Finally, transition of GIS developments and the practical applications over a half of century were reviewed by classifying into four terms. Recent trends of SF6 alternative gas and the related international activities in CIGRE and IEC were introduced. Also, features of GIS technologies in Japan were compared with those of overseas GIS in terms of e.g. design, manufacturing, testing techniques and the way to establish and update GIS specifications and standards.
