If 93 is opened, the no-load loss of the two transformers 54 and 94 is reduced, resulting in an energy saving effect. In addition, if the panel configuration is used as in the conventional example, the routing of the main circuit wiring becomes very complicated, but as in the example, one unit has two banks of wiring and disconnectors 41, 6.
2, 81, and 101, the main circuit wiring becomes simple and the structure is streamlined, which combines the advantages of system configuration and structure, resulting in a large space-saving effect. is born.
