Abstract

PURPOSE:To reduce an installation space for gas insulated contactors forming the primary and secondary wirings of gas insulated transformers by directly connecting the gas insulated contactors to the gas insulated transformers and positioning the gas insulated contactors above the gas insulated transformers. CONSTITUTION:Transformer primary wirings 3 are routed along the upper side of each gas insulated transformer 5, and one end of which is connected to the gas insulated transformer 5 through a connecting bus bar 4 and the opposite end of which is connected to a primary bus bar 9. And the transformer secondary wirings 14 are routed along the lower side of each gas insulated transformer 5, and one end of which is connected to the gas insulated trans former 5 through a connecting bus bar 15 and the opposite end of which is connected to a secondary bus bar 18. Since the primary wiring 3 and the secon dary wiring 14 of the transformer for each phase are routed along the upper and lower sides respectively of the gas insulated transformer for each phase as mentioned above, an installation space for the gas insulated transformer and contactors can greatly be reduced.
