GAS-OIL DIRECT CONNECTION THREE-PHASE INTEGRATION TYPE INSULTED PARTITION APPARATUS FOR ELECTRIC EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To provide a three-phase integration type insulated partition apparatus for electric equipment, which is configured in a compact size by making the diameter of a connection container small even if a silicone liquid is employed as an insulation oil for an oil-immersed transformer.

SOLUTION: The connection container 1 electrically connects a transformer filled with the silicone liquid 4 and a gas-insulated switchgear filled with a SF6 gas 5. A cone-shaped insulation spacer 3 is arranged and installed in the connection container 1, and partitions the silicone liquid 4 from the SF6 gas 5. Three-phase spacer supporting conductors 6 each penetrate through the respective approximate vertex positions of the regular triangle-shaped insulation spacer 3 for fixing and support. Transformer-side insulating coated conductors 7 are connected to the oil sealing-side ends 6a of the three-phase spacer supporting conductors 6, respectively. The gas-insulated switchgear connection conductors 8 are respectively connected to the gas filling ends 6b of the three-phase spacer supporting conductor 6. Each connection 9 between the oil sealing-side end 6a and the insulating coated conductor 7 is filled and covered with a shielding material, and aramid insulating paper is attached onto an outer surface of the shielding material.
