PURPOSE:To provide a switchboard in which a panel fixed with control members serves as a cover for main bus by disposing the panel closely to the main bus in the rear of a unit chamber. CONSTITUTION:A recessed fixed hinge 1d is disposed in the rear of a unit chamber on the side face of a box frame so that the fixed hinge 1d is fitted to a protruding movable hinge 13d disposed on a panel 13. When a main bus 6 is inspected with the panel 13 being fixed, fixing screws are removed from the panel 13 which is then drawn out with the lower notched part being engaged with a guide rail 11 while gripping the right and left handles thereof with hands. After drawing out the panel 13 to the position of a stopper 12, the movable hinge 1d is fitted in the fixed hinge and the panel 13 is rotated to be opened. This structure allows the maintenance and inspection of the bus 6 without removing the panel 13 from the switchboard. |
