This control device replacement method is a method for replacing an existing control panel (existing control device) 100 with a new control panel (new control device) 200, in particular, a new control at a position / location where the existing control panel 100 is installed. This is a method of installing the board 200.

  Here, first, the schematic structure and installation state of the control panels 100 and 200 will be described. However, since the existing control panel 100 and the new control panel 200 have the same structure and installation state, the existing control panel 100 is compared with the existing control panel 100. Only explained. That is, as shown in FIG. 9, the existing control panel 100 includes a cabinet-like / box-like cabinet 110 in which various control devices 120 and members (not shown) are accommodated. .

  The cabinet 110 mainly includes a frame 111 disposed on the installation floor 300, a side wall 112 and a door (side wall) 113 rising from each side of the frame 111, and a top plate as necessary. . The frame 111 is formed of an angle steel material or a rectangular steel material having an L-shaped cross section, and the planar shape is formed in a square frame shape (“B” shape), and is installed on the installation floor 300 extending in the horizontal direction. It is disposed on the installation floor 300 via the gantry 301. In addition, even when the opening 111a is formed by cutting a part of the frame 111 as described later, the material, the cross-sectional shape, etc. of the frame 111 are ensured to ensure necessary strength and rigidity. Is set.

  Two doors 113 are arranged to rise from the front side of the frame 111 (one side member constituting the frame 111), and side walls 112 are arranged to rise from both sides and the back side. Each door 113 is pivotally connected to the side edge of the adjacent side wall 112 so that the two doors 113 open and close like a double door.

  Here, in this embodiment, the frame 111 is positioned inside the side wall 112 and the door 113, that is, the side wall 112 and the door 113 rise from the side surface of the frame 111, but the side wall 112 extends from the upper end of the frame 111. In addition, the door 113 may rise and the frame 111 may be exposed to the outside. Further, the frame 111 and the side walls 112 may be integrally configured. That is, as will be described later, since only the front side of the frame 111 (side facing the door 113) is cut, the side excluding this side may be integrated with the side wall 112.

  On the other hand, a cable hole 302 (FIGS. 1 to 8) is formed in the installation floor 300 (in the frame 111) at the installation position of the existing control panel 100, and a cable processing chamber (not shown) below the floor (underground).

Thereby, the existing cable 130 will be in a power failure state.

  Next, as a removal step, the existing cable 130 is removed from the existing control panel 100, and the existing control panel 100 is removed through the new cable 230 into the opening 111 a of the frame 111. That is, first, as shown in FIG. 5, all the existing cables 130 are removed from the control device 120 of the existing control panel 100, pulled down from the installation floor 300, and removed from the cable processing chamber.

  Thereafter, as shown in FIG. 6, the control device 120 in the existing control panel 100 is removed to make the existing control panel 100 as light as possible (a state in which only the cabinet 110 is used as much as possible). Then, the existing control panel 100 is moved while passing the new cable 230 through the opening 111a of the frame 111, that is, over the new cable 230 with the opening 111a, and as shown in FIG. The board 100 is moved and removed from the installation space.

  Subsequently, as a moving step, the new control panel 200 is moved to the position where the existing control panel 100 has been installed. That is, the newly installed control panel 200 is moved from the state of FIG. 7 and placed on the mount 301 as shown in FIG. 8 and installed in the installation space where the existing control panel 100 was located. Then, the extra length of the new cable 230 is pulled and stored in the cable processing chamber.

  As described above, according to this control device replacement method, a part of the frame 111 of the existing control panel 100 is cut to form the opening 111a, and the new control panel 200 is connected to the opening 111a through the new cable 230. In order to remove, that is, since the new cable 230 can be straddled by the opening 111a, there is no need to lift (lift) the existing control panel 100. That is, a required extra length is not required for the existing cable 130, and a required gap is not required between the existing control panel 100 and the ceiling of the switchboard room. Therefore, the new control panel 200 can be installed at the position where the existing control panel 100 has been installed without being limited by the installation state, installation environment, or the like. That is, even if the space for installing the new control panel 200 cannot be secured, the existing control panel 100 can be more reliably replaced with the new control panel 200.

  Moreover, since it is only necessary to cut a part of the frame 111 of the existing control panel 100 to form the opening 111a, the replacement can be performed easily, quickly and safely. Further, since the required length of the existing cable 130 is not required, the cable cost can be reduced, and the replacement cost can be reduced because the existing control panel 100 does not need to be moved to another location. it can.
