<p>PROBLEM TO BE SOLVED: To simply supply power to a tower building block system by incorporating a power bus in the module of a tower system. SOLUTION: The power bus is incorporated in the module of the tower system. For example, a modularized power bus is arranged on printed circuit boards 10 and 12, each of which is mounted to the module or the building block of the tower building block system. Then there are two power bus outlets on the side surfaces of the boards 10 and 12. There are two three-phase power buses on the circuit boards. Then, in order to supply power of one phase from each of the two power buses of the board 10, power outlets 22 and 24 on the board 10 are connected. Similarly, in order to supply power of one phase from each of the two power buses of the board 12, power outlets 23 and 25 on the board 12 are connected.</p> |
