Title:
SWITCHGEAR BUS CONNECTION STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2004/051816
Kind Code:
A1
Abstract:
A switchgear bus connection structure having a reduced number of components and produced with improved connection workability at low cost. T bushings are gas−tightly attached to respective insulating gas enclosed containers in such a way that an end of a branch conductor is electrically connected to a feed circuit and ends of busses adjoin to each other coaxially. A connection conductor is slidably fitted on the pair of ends of the opposed busses while maintaining the electrical contact. An insulating tube of an elastic material covers the connection conductor and the ends of the busses and is fitted on a pair of opposed insulators while being radially enlarged in such a way that the conductive coatings of the paired opposed insulators are electrically short−circuited through a grounding conductive layer. Thus the number of components is reduced, the connection workability is improved, and the cost is lowered.
