<p>PROBLEM TO BE SOLVED: To obtain a 1 to 1/2 system gas-insulated switchgear which reduces deterioration of interpolar capacitors, has a simple construction and is small- sized by removing the capacitors out of metal containers for circuit-breakers, and housing apparatuses in the metal containers collectively. SOLUTION: Three units 100, 200, 300 which have, in the metal containers 101, 201, 301 filled with insulation gases and grounded, at least power-circuit circuit breakers 102, 202, 302, disconnectors 103, 104, 203, 204, 303, 304 and grounding switches 120, 220, 320 which are arranged and connected respectively to both ends of these circuit breakers, are connected in series to each other successively. A capacitor 48 is arranged respectively near each bushing 403, 404 and connected to a load side, and load-side disconnectors 205, 206 are installed in the metal containers.</p> |
