<p>PROBLEM TO BE SOLVED: To reduce depth size and enlarge the facility to eliminate the need for the rearrangement of power cable during expansion of facility by connecting front surface of both end portions to a connecting container accommodating a connecting bus at the rear surface of main circuit container and branching container, and then connecting both connecting portions with the connecting bus. SOLUTION: A branching rack 10 is provided at the side of the main tack 5, a front surface of both end portions of bus connecting container 13 is connected to the rear surface of the main circuit container 6 on the main rack 5 and the branching container 11 on the branching rack 10, the main circuit cable connecting portion is connected to the branching circuit cable connecting portion CHd2 by the connecting bus BUS', depth size can be reduced, and installation area can also be reduced. When the facility is enlarged and reinforced, the branching container 11 and bus connecting container 13 are removed and a manipulating box 2', circuit breaker container 3' and bus container 4' and main circuit container 6' are provided at the side of main circuit unit to form the power transmission line circuit unit.</p> |
