Abstract

PURPOSE:To make the promotion of the cost down with an elimination made of the expensive spacer necessary in the past, by changing a use of solid-air hybrid insulated bus in the past into a use of solid-SF6 gas hybrid bus. CONSTITUTION:In the enclosed type switchgear, where constitutional equipments of bus, breaker, disconnector, etc. and SF6 gas are contained, an insulating coat is applied to a bus 3 that connects each circuits, with said bus supported by an insulation support unit 19. If constructed in such way, the voltage distribution, between the insulation coating and the SF6 gas, becomes to be mainly applied for the SF6 gas, causing an electric stress very small in the insulation coating unit, capable of also obtaining a low cost construction. And because an application of the insulation coating plays also a role of electric field relaxation, especially a use of SF6 gas, with a determined insulation strength at the maximum intensity of electric field, can reduce dimensions of the device.
