Displays the drive mode. The driving mode display bar 72 has one end portion moved along the ramp 49 as the switchboard unit 20 moves, and the other end portion is connected to one end portion and exposed to the display window 65 installed on the door 25. The drive mode of the switchboard unit 20 is displayed. The other end is provided with a display panel 78a for displaying the driving mode of the switchboard unit 20, that is, the driving mode, the test mode, and the off mode in the form of a line or a strip. The driving mode display bar 72 is movably installed in the elastic bar driving module 50 installed inside the switchboard unit 20. The driving mode display bar 72 is installed on the outer surface of the case 71 so as to be movable through the first and second connection pins 121 and 123.

The driving mode display bar 72 includes a moving unit 74, a connecting unit 76, and a display unit 78. One end of the moving part 74 is rotatably installed on the outer surface of the case 71 via the first connecting pin 121, and the other end thereof moves in contact with the inclined table 49. The connecting portion 76 is integrally formed with one end of the moving portion 74 and extends toward the inner surface of the door 25. In addition, the display unit 78 is integrally formed with the connection unit 76, and converts the rotational movement of the moving unit 74 to the vertical movement to display the driving mode. The display portion 78 has a slot 78b formed in a vertical direction on the side connected to the connecting portion 76, and is formed on the outer surface of the case 71 via a second connecting pin 123 inserted into the slot 78b. Is installed. At an end portion of the display portion 78, a display panel 78a displaying a drive mode is provided. The display panel 78a displays the current driving mode toward the display window 65. Therefore, when the moving unit 74 moves on the slope 49 as the switchboard unit 20 moves, the moving unit 74 and the connecting unit 76 rotate, and thus the display unit connected to the connecting unit 76 ( 78 is moved up and down by the first connecting pin 123 connected to the slot 78b to display the changed driving mode on the display panel 78a. For example, when the moving part 74 is in the horizontal surface 49b of the inclination table 49, the display panel 78a displays a driving mode. When the moving part 74 is in the inclined surface 49a, the display panel 78a displays the test mode. Then, when the moving unit 74 completely descends the ramp 49, the off mode is displayed.

The method of guiding the position according to the driving mode of the switchboard unit 20 by the position guide device 30 according to the present embodiment will be described with reference to FIGS. 10 and 11 as follows. 10 is a view showing an operation mode of the switchboard unit 20 according to the embodiment of the present invention. 11 is a view showing a test mode of the switchboard unit 20 according to the embodiment of the present invention.

In this case, when the switchboard unit 20 is in the operation mode, as shown in FIG. 10, the first elastic bar 53 is inserted into the first locking hole 46 to adjust the position according to the operation mode of the switchboard unit 20. Guide exactly. When the switchboard unit 20 is in the test mode, as shown in FIG. 11, the second elastic bar 55 is inserted into the second locking hole 47 to adjust the position according to the test mode of the switchboard unit 20. Guide exactly.

First, a case in which the driving mode of the switchgear unit 20 is changed from the driving mode to the test mode is as follows.

As shown in FIG. 10, in the operation mode, the first elastic bar 53 is inserted into the first locking hole 46, and the second elastic bar 55 is positioned on the upper surface of the guide rail plate 40. do. At this time, the second elastic bar 55 is in a state in which elastic force is accumulated by the increased second spring (77b in FIG. 4).

Next, when the operator switches the lever (91 in Fig. 8) to the test mode in order to switch from the operation mode to the test mode, the key of the locking module (89 in Fig. 4) is the keyhole (Fig. 4) in the connecting rod (75 in Fig. 4). 4, 79) to unlock the elastic bar operation button (61 in FIG. 8).

Next, when the operator presses the first elastic bar operation button (61a in FIG. 8), the switchboard unit 20 is in a state capable of moving forward by riding on the guide rail plate 40. At this time, when the first elastic bar operation button (61a of FIG. 8) is pressed, the first elastic bar 53 is moved out of the first locking hole 46 and moves above the upper surface of the guide rail plate 40. Therefore, the switchboard unit 20 is in a state in which the guide rail plate 40 can move.

In this state, when the switchboard unit 20 is pulled forward, as shown in FIG. 11, the second elastic bar 55 moves on the guide rail plate 40 and then is located in the second locking hole 47. If so, it is inserted into the second locking hole 47 by the elastic force accumulated by the second spring (77b of FIG. 6). Therefore, the switchboard unit 20 is no longer moved forward by riding the guide rail plate 40.

That is, in the position guide device 30 according to the present embodiment, when the switchboard unit 20 moves to a position where the test mode can proceed, the switchboard unit is inserted into the second locking hole 47 by inserting the second elastic bar 55 into the second locking hole 47. Prevent the movement of (20). At this time, when the force which pressed the 1st elastic bar operation button 61a is removed, the 1st elastic bar 53 is located on the upper surface of the guide rail board 40. FIG.

4, 6, and 8, the driving mode display bar 72 indicates that the driving mode is switched from the driving mode to the test mode. That is, in the driving mode, since the driving mode display bar 72 is on the horizontal surface 49b of the inclined table 49, the display panel 78a of the driving mode display bar 72 displays the driving mode. do. When the switchboard unit 20 moves from the driving mode to the test mode, the moving unit 74 moves from the horizontal plane 49b to the inclined plane 49a so that the display panel 78a displays the test mode.

On the other hand, when performing the test mode, since the plurality of elastic bar operation buttons 61 are exposed to the operation state, the operator can use the on / off key (67 in FIG. 9) to control the plurality of elastic bar operation buttons ( 61) operation can be prevented.

On the contrary, the case where the driving mode of the switchboard unit 20 is changed from the test mode to the operation mode will be described.

First, when the operator presses the second elastic bar operation button (61b of FIG. 8), the switchboard unit 20 is in a state capable of moving backward by riding the guide rail plate 40. At this time, when the second elastic bar operating button (61b of FIG. 8) is pressed, the second elastic bar 55 is moved out of the second locking hole 47 and moves above the upper surface of the guide rail plate 40. Therefore, the switchboard unit 20 is in a state in which the guide rail plate 40 can move. At this time, the first elastic bar 53 is also on the upper surface of the guide rail plate 40.
