The push bar 113 is formed in a direction substantially perpendicular to the movement bar 111 and a key hole 79 into which the key 89 of the lock module 80 is inserted is formed.

In order to suppress the interference between the plurality of elastic bars 51 engaged with the plurality of gears 73 and the plurality of linking blocks 75 and to reduce the space for installing the first gears 73a and the second gears 73b, It is installed in a viewing position. The first and second linking portions 75a and 75b connected to the first gear 73a and the second gear 73b are vertically disposed at positions facing each other. It is of course possible to move the elastic bar 51 to the upper surface of the guide rail plate 40 by pressing the elastic bar operation button 61. The plurality of elastic bars 51 and the plurality of A connecting rod 75 is connected.

The plurality of springs (77) connect the plurality of connecting rods (75) and the case (71), respectively. At this time, the spring 77 is fixed to the spring insertion hole 117 formed in the movement bar 111 of the connection block 75 at one end, and the other end is fixed to the part 71 of the case 71 near the push bar 113 of the connection block 75 As shown in Fig. Therefore, when the elastic bar operating button 61 is pressed to move the connecting bar 75, the spring 77 is stretched. When the force pressing the elastic bar operating button 61 is removed, the spring 77 contracts, And the elastic bar operation button 61 to their original positions. The plurality of springs 77 includes a first spring 77a connected to the first connecting rod 75a and a second spring 77b connected to the second connecting rod 75b.

The elastic bar driving module 50 may further include a power switch at an upper end thereof. This power switch is characterized in that it is closed when the elastic bar 51 is raised (when the lower end of the elastic bar is inserted into the locking hole). Since the power switch corresponds to each elastic bar, it can be seen that the position guiding device 30 according to the embodiment of the present invention includes two pieces. When the first elastic bar (53) is positioned on the upper surface of the guide rail plate (40), the first switch closes the first switch and the second switch closes the second elasticity When the bar 55 is positioned on the upper surface of the guide rail plate 40, the upper end of the second elastic bar 55 closes the second switch. When the switch is closed, power is supplied to the bulb (power source display device) connected to each switch, and a display of the heat is made. For example, in the test mode, when the first elastic bar 53 is positioned on the upper surface of the guide rail plate, the upper end of the first elastic bar 53 closes the first switch. At this time, when the power is supplied, the bulb flashes and the operation state can be known. This power supply is performed when the lock shaft 93 is rotated by rotating the lever 91. It can be seen that the second switch is closed in the operation mode.

20 and 21 are plan views for explaining a driving method of the adjusting plate according to the embodiment of the present invention.

The adjustment plate 79a allows the shut-off bar 72a to rotate. The adjustment plate 79a may include a plurality of adjustment plates, but preferably two adjustment plates 79b and 79c.

A bent portion 79e is formed on one side of each of the adjusting plates 79a and a vertical portion 79d is formed on the other side of the adjusting plate 79a. The bent portion 79e is in contact with the protrusion 74a formed in the shut-off bar 72a. When the adjusting plate 79a is rotated, the protrusion 74a moves due to the inner bending of the bent portion 79e, thereby causing the blocking bar 72a to rotate. The vertical portion 79d is in contact with one end of the linkage 75. More specifically, it is preferable that a vertical portion 79d is inserted between two gear teeth 115 formed on the outermost side of the linkage 75. Accordingly, when the connecting rod 75 moves left and right, the adjusting plate 79b also rotates in both directions with respect to one axis. That is, when the connecting rod 75 moves into the elastic bar driving unit 70, the adjusting plate 79a rotates, and the blocking bar 72a also rotates due to the rotation of the adjusting plate 79a.

The inclined stage 49 is installed on the upper surface of the guide rail plate 40 in parallel to the moving direction of the switchboard unit 20. [ The inclined surface 49a of the ramp 49 is inclined upward inward from the side where the insertion of the switchboard unit 20 is started and the rear side of the inclined surface 49a is formed as a horizontal surface 49b having a constant height, An induction groove 49c into which the moving part 74 of the drive mode indicating bar 72 is inserted is formed between the ends of the shutters 49a and 49a and the end of the horizontal surface 49b, A plurality of insertion grooves 49d and 49e into which the arm portions 74b are inserted are formed. At this time, an insertion hole 21b through which the inclined stage 49 is exposed is formed on the bottom surface of the switchboard unit 20 corresponding to the inclined stage 49. The driving mode indicating bar 72 and the shut-off bar 72a are moved in contact with the inclined stage 49 through the insertion hole 21b.

The driving mode display bar 72 is connected to the current mode through the display window 65 provided on the door 25, that is, the display window 65 of the door case 63, together with the driving mode displayed on the mode switching device 80. [ Display the drive mode. One end of the drive mode indicator bar 72 is moved along the inclined stage 49 in accordance with the movement of the switchboard unit 20 and is connected to one end of the drive mode indicator bar 72 to be exposed to the display window 65 provided on the door 25 And the drive mode of the switchboard unit 20 is displayed. And a display panel 78a for displaying the drive mode of the switchboard unit 20, that is, the operation mode, the test mode, and the off mode, in the form of a line or a band, is provided at the other end. The drive mode display bar 72 is movably installed in the elastic bar drive module 50 provided inside the switchboard unit 20. The drive mode display bar 72 is installed on the outer surface of the case 71 so as to be movable through first and second connection pins 121 and 123.

The drive 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 of the moving part 74 moves in contact with the inclined stage 49. The connecting portion 76 is integrally formed with one end portion of the moving portion 74 and extends toward the inner side surface of the door 25. The display unit 78 is formed integrally with the connection unit 76 and converts the rotational movement of the moving unit 74 into a vertical movement to display a driving mode. The display portion 78 is formed with a slot 78b in a direction perpendicular to the connecting portion 76 and connected to the outer surface of the case 71 via the second connecting pin 123 inserted in the slot 78b Respectively. At the end of the display portion 78, a display panel 78a for displaying the drive mode is provided. The display panel 78a displays the current drive mode toward the display window 65. [ The moving part 74 and the connecting part 76 are rotated when the moving part 74 moves along the inclined stage 49 in accordance with the movement of the switchboard unit 20 so that the display part 78 are vertically moved by the first connection pin 123 connected to the slot 78b to display the drive mode switched to the display panel 78a. For example, when the moving part 74 is on the horizontal plane 49b of the inclined plane 49, the display panel 78a indicates the operation mode. When the moving section 74 is on the inclined surface 49a, the display panel 78a displays the test mode. When the moving part 74 completely descends the inclined stage 49, the off mode is displayed.

The blocking bar 72a is provided between the driving mode indicating bar 72 and the elastic bar driving module 50. The blocking bar 72a has a shape similar to that of the composition mode display bar 72 but has different functions. The blocking bar 72a prevents the blocking portion 78c from moving in the direction of the elastic bar driving module 50. In Fig. 14, the blocking bar 72a is shown at the lower side, and in Fig. 15 to 17, the blocking bar 72a is shown at the upper side. When the blocking bar 72a is located at the upper side, the key 89 is blocked by the blocking portion 78c and can not move to the elastic bar driving module 50 side. Accordingly, when the shut-off bar 72a is located at the upper side, the rotation of the rotation plate 81 is restricted and the power supplied to the switchboard unit 20 is cut off.

 One end of the blocking bar 72a moves along the inclined stage 49 in accordance with the movement of the switchboard unit 20 and the moving portion 74d is inserted into the insertion holes 49d and 49e in the test mode and the drive mode. At this time, the blocking portion 78c is located at the lower side, and the movement of the key 89 becomes free. In this case, power can be supplied to the switchboard unit.

The blocking bar 72a also includes a slot 78d. When the movable portion 74b moves along the inclined stage in accordance with the movement of the switchboard unit 20, the movable portion 74b and the connecting portion 76a rotate, and thus the blocking portion 78c connected to the connecting portion 76a And moved up and down by a first connection pin 123 connected to the slot 78d.

The protrusion 74a of the blocking bar 72a has a shape that enters into the elastic driving module 50 through a hole formed in the case. The hole formed on the case is formed to be sufficient for the projection 74a to move. The projection 74a contacts the plurality of adjustment plates 79 and the projection 74a moves as the adjustment plate 79 rotates and as a result the blocking bar 72a rotates.

A method of guiding the position guiding device 30 according to the driving mode of the switchboard unit 20 according to the present embodiment will be described with reference to FIGS. 11 and 12. FIG. 11 is a view showing an operation mode of the switchboard unit 20 according to the embodiment of the present invention. 12 is a diagram showing a test mode of the switchboard unit 20 according to the embodiment of the present invention.

11, the first elastic bar 53 is inserted into the first locking hole 46 to change the position of the switchboard unit 20 according to the operation mode I will guide you exactly. 12, the second elastic bar 55 is inserted into the second locking hole 47 to change the position of the switchboard unit 20 according to the test mode I will guide you exactly.

First, the case of switching the drive mode of the switchboard unit 20 from the operation mode to the test mode will be described.

11, in the operation mode, the first elastic bar 53 is inserted into the first locking hole 46, and the second elastic bar 55 is inserted into the upper surface of the guide rail plate 40 do. At this time, the second elastic bar 55 is in a state in which the elastic force is accumulated by the second spring (77b in Fig. 6) stretched.

Next, when the operator switches the lever (91 of FIG. 9) to the test mode to switch from the operation mode to the test mode, the key of the lock module (89 in FIG. 4) 4 of 79) and unlocks the elastic bar operation button (61 of Fig. 9).

Next, when the operator pushes the first elastic bar operation button (61a in Fig. 9), the switchboard unit 20 becomes able to move forward by riding the guide rail plate 40. [ At this time, when the first elastic bar operation button (61a of FIG. 9) is pushed, the first elastic bar 53 moves out of the first locking hole 46 and moves over the upper surface of the guide rail plate 40. Therefore, the switchgear unit 20 can move in the guide rail plate 40.

11, the second elastic bar 55 is moved on the guide rail plate 40 and then is moved to the second locking hole 47 in the second locking hole 47. In this state, , It is inserted into the second locking hole 47 by the elastic force accumulated by the second spring (77b in Fig. 7). Therefore, the switchboard unit 20 is no longer moved forward by the guide rail plate 40.

That is, when the position guiding device 30 according to the present embodiment moves to a position where the switchboard unit 20 can proceed to the test mode, the second elastic bar 55 is inserted into the second locking hole 47, (20). At this time, when the force applied to the first elastic bar operation button 61a is removed, the first elastic bar 53 is positioned on the upper surface of the guide rail plate 40.

In the operation mode, the moving part 74b is inserted into the second insertion groove 49e of the inclined stage 49 so that the blocking part 78c does not restrict the movement of the key 89. [ In the operation mode, the key 89 is inserted into the slot of the linking unit 75b to lock the linking unit 75.

Also, as shown in FIGS. 4, 7, and 9, it indicates that the driving mode is switched from the operation mode to the test mode through the drive mode display bar 72. [ The drive mode indicator bar 72 is located on the horizontal plane 49b of the inclined stage 49 so that the indicator plate 78a of the drive mode indicator bar 72 displays the operation mode do. When the switchboard unit 20 is moved from the operation mode to the test mode, the moving unit 74 moves from the horizontal plane 49b to the inclined plane 49a, and the display board 78a displays the test mode.

In the test mode, the moving part 74b is inserted into the first insertion groove 49d of the inclined stage 49 so that the blocking part 78c does not restrict the movement of the key 89. [ In the test mode, the key 89 is inserted into the slot of the linkage 75a, and the linkage 75 is locked.

On the other hand, when performing the test mode, since the plurality of elastic bar operation buttons 61 are exposed in an operable state, the operator can use the on / off key 67 to press the plurality of elastic bar operation buttons 61 The operation can be prevented.

Conversely, a case of switching the drive mode of the switchboard unit 20 from the test mode to the operation mode will be described as follows.

First, when the operator presses the second elastic bar operation button (61b in Fig. 9), the switchboard unit 20 can move backward along the guide rail plate 40. [ At this time, when the second elastic bar operation button 61b is pressed, the second elastic bar 55 moves out of the second locking hole 47 and moves over the upper surface of the guide rail plate 40. Therefore, the switchgear unit 20 can move in the guide rail plate 40. At this time, the first elastic bar 53 is also on the upper surface of the guide rail plate 40.

In this state, when the switchboard unit 20 is pushed backward and the first elastic bar 53 moves on the guide rail plate 40 and then is positioned in the first locking hole 46, 7 by the elastic force accumulated by the first locking hole 46a. Therefore, the switchboard unit 20 no longer moves backward along the guide rail plate 40.

When the lever (91 in Fig. 9) is switched from the test mode to the operation mode, the key (89 in Fig. 5) of the lock module is inserted into the keyhole 79 of the linkage (75 in Fig. 5) 9).

Also, as shown in FIGS. 4, 7, and 9, the drive mode display bar 72 indicates that the drive mode is switched from the test mode to the operation mode. In the test mode, since the moving part 74 of the driving mode indicating bar 72 is located on the inclined surface 49a of the inclined stage 49, the indicating plate 78a of the driving mode indicating bar 72 displays the test mode . When the switchboard unit 20 is moved from the test mode to the operation mode, the moving unit 74 moves from the inclined plane 49a to the horizontal plane 49b, and the display panel 78a displays the operation mode.

In the test mode, the moving part 74b is inserted into the first insertion groove 49d of the inclined stage 49, and the blocking part 78c does not restrict the movement of the key 89. [ That is, the key 89 is movable to be inserted into the slot 75 of the linkage.

No power should be supplied between test mode and operation mode. In normal service mode, a very large voltage is supplied, while in test mode, a small voltage is supplied. In the test mode, there is no safety problem because the voltage is small, but in case of the operation mode, safety problems may occur. To solve this problem, it is necessary to prevent the rotation of the lever 91 between the test mode and the operation mode. The lever is rotated only when the moving part 74b of the blocking bar 72a is inserted into the insertion groove 49d or 49e of the inclined plate 49 and the moving part 74b is rotated on the horizontal plane 49b The blocking portion 78c is positioned at the upper side and the key 89 is not moved toward the elastic bar driving module 50 at this time so that the rotation of the lever 91 is also restricted. That is, the rotation of the lock shaft 93 is restricted, and power supply to the switchboard unit 20 is blocked. Therefore, between the test mode and the operation mode, the power supply is essentially shut off, thereby solving the problem of electric shock.

The case of switching the drive mode of the switchboard unit 20 from the test mode to the off mode will be described as follows.

 First, the lever 91 is switched from the test mode to the off mode, and the power supplied to the switchboard unit 20 is cut off.

Next, when the worker pulls the switchboard unit 20 forward by holding the second elastic bar operation button (61b in Fig. 8), the switchboard unit 20 moves on the guide rail plate 40 to the front side . At this time, when the second elastic bar operation button (61b of FIG. 8) is pressed, the second elastic bar 55 moves out of the second locking hole 47 and moves over the upper surface of the guide rail plate 40. Therefore, the switchgear unit 20 can move in the guide rail plate 40. The first elastic bar (53) is also on the upper surface of the guide rail plate (40).

Since the first and second elastic bars 53 and 55 are positioned on the upper surface of the guide rail plate 40 in this way, the switchboard unit 20 can be completely separated from the guide rail plate 40.

Also, as shown in Figs. 4, 7, and 9, it indicates that the drive mode is switched from the test mode to the off mode through the drive mode display bar 72. [ In the test mode, since the moving part 74 of the driving mode indicating bar 72 is located on the inclined surface 49a of the inclined stage 49, the indicating plate 78a of the driving mode indicating bar 72 displays the test mode . When the switchboard unit 20 moves from the test mode to the off mode, the moving part 74 moves from the inclined surface 49a to the upper surface of the guide rail plate 40, and the display panel 78a displays the off mode.

A case of switching the drive mode of the switchboard unit 20 from the off mode to the test mode will be described as follows. Here, the case where the first and second elastic bars 53 and 55 are on the upper surface of the guide rail plate 40 will be described.

First, when the operator pushes the switchboard unit 20 backward, the switchboard unit 20 moves backward along the guide rail plate 40. At this time, since the first and second elastic bars 53 and 55 are on the upper surface of the guide rail plate 40, the switchboard unit 20 becomes movable in the guide rail plate 40.

When the switch board unit 20 is pushed backward in this state and the second elastic bar 55 moves on the guide rail plate 40 and then is positioned in the second locking hole 47, And is inserted into the second locking hole 47 by the elastic force accumulated by the second locking hole 47. [ Therefore, the switchboard unit 20 no longer moves backward along the guide rail plate 40.

Then, the lever 91 of the mode switching device 90 is switched from the off mode to the test mode.

Also, as shown in Figs. 4, 7 and 9, it indicates that the drive mode is switched from the off mode to the test mode through the drive mode display bar 72. [ The display panel 78a of the drive mode display bar 72 displays the off mode because the moving part 74 of the drive mode display bar 72 is on the upper surface of the guide rail plate 40 . When the switchboard unit 20 moves from the off mode to the test mode, the moving part 74 moves from the upper surface of the guide rail plate 40 to the inclined surface 49a, and the display panel 78a displays the test mode.

The mode switching device 90 according to the present embodiment will be described in more detail with reference to FIGS. 1, 2, 10, and 19. Here, FIG. 19 is a plan view for explaining a driving method of the mode switching device 90.

The mode switching device 90 includes a lock shaft 93, a lock module 80, and a lever 91. The lock shaft 93 protrudes from the unit drive module 23 of the switchboard unit 20 toward the door 25 of the switchboard unit 20 and is rotatable. The lock module 80 is fixed to the switchboard unit 20 inside the door 25 and is coupled through the lock shaft 93. The lever 91 is installed on the outer surface of the door 25 and the lock shaft 93 is engaged to rotate the lock shaft 93 to switch the drive mode of the switchboard unit 20. [

The lever 91 displays a drive mode according to the position of the lever 91 so that the operator can easily confirm the current drive mode. The operation mode, the test mode and the off mode can be displayed in the rotation direction of the lever 91. [

The lock module 80 includes a rotary plate 81, a key shaft 87, and a key 89.

The rotary plate 81 has a hole through which the lock shaft 93 can be inserted so as to be movable in the longitudinal direction of the lock shaft 93 and has a through hole through which a coupling member can be connected to one side of the periphery. The key shaft 87 is rotatably coupled to one side of the rotary plate 81 and extends in the longitudinal direction. At both ends of the key shaft 87, a through hole through which the engaging member can be connected is formed. The key 89 is rotatably connected to one end of the key shaft 87. The key 89 is formed at one end thereof with a through hole and is connected to the through hole of the key shaft 87 through the coupling member to be rotatable . In general, a connecting pin may be used as the engaging member.

The locking module 80 may further include a separate key guide 84. The key guide 84 includes a key groove 84a that allows the key to be linearly moved. And an engaging groove 84b of an elastic bar driving module to which one end of the elastic bar driving module 50 is coupled is formed.

Further, since the rotary plate 81 has a rotatable structure, the lock module 80 can be positioned corresponding to the position where the lock shaft 93 and the key 89 are located. The lock module 80 may be connected to the lock shaft 93 so as to be inclined with respect to a horizontal plane on which the key 89 is located when the lock shaft 93 is not positioned on the horizontal plane where the key 89 is located.

The key 89 is rotatably installed at one end of the key shaft 87 through a fixing member. The key 89 is released or inserted into the keyhole 79 of the connecting block 75 to perform locking and unlocking of the elastic bar operation button 61 in accordance with the movement of the key shaft 87. [

The size of the lock module 80 varies depending on the size of the switchboard unicirc 20. However, it is not difficult to manufacture a separate key shaft 87. In addition, although it is possible to consider a configuration in which the length of the key shaft 87 can be adjusted, there is a problem in that it is not advantageous in comparison with an increase in manufacturing cost. Further, complicating the configuration of the lock module 80 is not advantageous in terms of cost.

An operation relationship between the locking module 80 and the position guide device 30 when the mode is switched to the mode switching device 90 according to the present embodiment will be described with reference to FIG. 19.

First, an example of conversion from the test mode to the operation mode will be described as follows.

When the locking module 80 is locked to the switchboard unit 20 in the examination mode and the driving mode, the key 89 of the locking module 80 is inserted into the keyhole 79 of the connecting table 75. In this case, the switchboard unit 20 can not move due to an external force.

In this state, in order for the operator to switch from the test mode to the operation mode, when the lever 91 is turned counterclockwise, the key 89 is released from the keyhole 79, and when the operator presses the elastic bar operation button 61, The elastic bar 51 is raised up so that the switchboard unit 20 can freely move back and forth. At this time, the switchboard unit 20 may be changed to the operation mode position, and when the lever (91 in FIG. 9) of the mode switching device 90 is rotated clockwise, the key 89 of the locking module 80 is connected to the connecting table 75. Is inserted into the keyhole 79 to lock the elastic bar operation button 61. That is, when the lock shaft 93 connected to the lever 91 rotates clockwise by rotating the lever 91, the rotating plate 81 coupled to the lock shaft 93 rotates clockwise. Thus, the key 89 connected to the key shaft 87 is inserted into the key hole 79 of the connecting table 75. The rotation of the lever 91 causes the locking module 80 and the position guide device 30 to bind to each other in the driving mode, and power is supplied to the switchboard unit 20.

Next, the method of switching from the operation mode to the test mode is possible by rotating the lever 91, in which the key 89 is removed from the keyhole 79 of the connecting table 75. The driving of the locking module 80 of the mode switching device 90 is performed in the opposite direction to the switching to the driving mode described above.

It should be noted that the embodiments of the present invention disclosed in the present specification and drawings are only illustrative of specific examples for the purpose of understanding and are not intended to limit the scope of the present invention. It will be apparent to those skilled in the art that other modifications based on the technical idea of the present invention are possible in addition to the embodiments disclosed herein.
