Patent ID: 7764486

Claim:
A gas-insulated power apparatus comprising a vertically arranged gas-insulated circuit breaker included in a vertically arranged gas-insulated main tank, a first gas-insulated branch pipe connected to one side of an upper portion of the gas-insulated main tank substantially orthogonal to a direction of extending of the gas-insulated main tank and leading out a feeder from a movable side of the gas-insulated circuit breaker, a second and a third gas-insulated branch pipes which are respectively connected to both sides in a peripheral direction of a lower portion of the gas-insulated main tank substantially orthogonal to the direction of extending of the gas-insulated main tank, one of which connects a fixed side of the gas-insulated circuit breaker to one gas-insulated Y bus of gas-insulated double buses and the other of which connects the fixed side of the gas-insulated circuit breaker to the other gas-insulated X bus of the gas-insulated double buses, respectively, a first connection conductor in a linear shape arranged inside of the gas-insulated main tank for connecting the gas-insulated Y bus of the one of the gas-insulated double buses and the gas-insulated X bus of the other of the gas-insulated double buses, and a second connection conductor in a linear shape which is arranged inside of the gas-insulated main tank, an upper end of which is connected to the gas-insulated circuit breaker and a lower end of which is connected to the first connection conductor, respectively.
