Gas insulated switchgear equipment including a bypass bus and bypass disconnecting switch

摘要

A power receiving unit is arranged in one side of an instrument potential/current unit transformer. A transformer-side unit is arranged in the other side of the instrument potential/current transformer units. A bypass bus connecting the power receiving unit and the transformer-side unit is arranged in parallel to the row of cubicles. The gas insulated switchgear can be made small in size and the work for adding a bank can be performed with substantially small man-power. The size of the gas insulated switchgear can be also prevented from increasing due to the addition of a bank.
