GAS INSULATED SWITCH - HITACHI LTD

Title:

GAS INSULATED SWITCH

Document Type and Number:

WIPO Patent Application WO/2001/024333

Kind Code:

A1

Abstract:

A plurality of T-branch breaker units (12) are arrayed perpendicularly to their branching direction and are connected alternately in a square wave shape in series in a horizontal plane substantially at the same level as that of the T-branch portions thereof through first connection bus units (14) and second connection bus units (15). As a result, a first connection bus (5) and a second connection bus (6) are laid in the horizontal plane at the same level as that of the T-branch portions of the breaker units (12) but not in the vertical direction. Thus, the lengths of the connection buses are short and the cost is low.
