要約(英語): A large number of aged switchgears are now operating in the field. However it is difficult to obtain maintenance parts for aged switchgear, and the main components are manifesting signs of degradation due to their longtime operation. As a solution to the issue, systematic replacement of aged switchgears is being planned to maintain their reliability. On the other hand, the replacement equipment must fulfill certain requirements such as minimization of the outage area, shortening of the replacement period, maximization of the usage of existing facilities such as equipment foundations, and easy connection with existing equipment. The enclosure size of the conductor has been reduced in the effort to streamline various areas such as the reduction of phase-to-phase impulse test voltage and the limitation of temperature rise. Along with the use of the new spacer, we were able to develop a simplified GIB. This will be used in future projects involving refurbishment of aged substation equipments.
