<p>PROBLEM TO BE SOLVED: To reduce working hours by providing a common base, a plurality of unit bases provided on the common base and a plurality of gas insulating switching units provided on the unit bases for every circuit. SOLUTION: Gas insulating switching units 13 can be divided into a load side block 14 for housing a load side equipment and a bus disconnecting switch block 15 mounted on the load side block 14, and after the units 13 are assembled on unit bases 12 in parallel work, the units 13 are installed and connected to a common base 11 and are conveyed in the lump. The common base 11 is installed on an embedded base in an installation site, and when the load side block 14 is required to carry out because of having any trouble with an equipment in the load side block 14 or any changes in the load side block 14 after the installation, the bus disconnecting switch 15 remains behind, and the load side block 14 is only made to carry out to carry on the operation of the bus bar. As a result, work efficiencies of assembly work in a plant and installation work in a stie can be promoted to make it possible to reduce working hours.</p> |
