BUSHING FOR GAS-INSULATED ELECTRICAL EQUIPMENT

摘要

This invention consists in that inside a porcelain tube (2) of a bushing (1) which employs a gaseous insulator, an insulating tube (7) is disposed with a space of small volume set relative to the inner periphery of the porcelain tube (2), and that the small space is filled with an insulating medium (9) which is deformable with a predetermined force. According to the construction, when the porcelain tube (2) has damaged, its fragments can be prevented from scattering far. The flashover of the bushing (1) can be prevented by disposing compression springs (34) in the lower part of the insulating tube (7), and the electric field distribution of the outer surface of the bushing (1) can be improved by coating the surface of the insulating tube with an electrically conductive coating material (41).
