<p>PROBLEM TO BE SOLVED: To improve bus-bar connections between a receiving unit, whose bus-bar lead-out positions are on its lower side and an MOF unit whose bus-bar entrance positions are on its upper side, reduce the size and weight of a row- arranged gas-insulated switchgear and realize workability improvement and cost reduction. SOLUTION: A gas-insulated switchgear has a receiving unit 1, in which an insulating gas is sealed and whose bus-bar lead-out position is on its lower side, and an air-insulating type MOF unit 2 whose bus-bar entrance position is on its upper side and both the units 1 and 2 are arranged in a row. Bus-bar lead-out terminals 22 of cable heads, etc., which are attached to the lower part of the side plate of the receiving unit 1 on the MOF unit side 2 to penetrate the side plate airtightly and whose inside ends positioned in the receiving unit 1, are connected to the bus-bars 3 of the receiving unit 1 and bus-bar connection elements between units (power cables 27), which comprise covered conductors such as power cables housed in the MOF unit, whose lower ends are connected to the outside ends of the bus-bar lead-out terminals 22 which are positioned in the MOF unit 2 and whose upper ends are connected to the bus-bars 4 of the MOF unit 2, are provided.</p> |
