[0009] [Explanation of the Switchboard Including a Drawer-Type Device as a Reference Example] Figure 1 It is a reference diagram showing the overall structure for explaining the switchboard including a drawer-type device of the present application. Here, first, before explaining the switchboard including a drawer-type device according to the embodiment of the present application, based on Figure 1 the reference diagram, the overall structure of the switchboard including a drawer-type device is explained.

[0010] Figure 1In the figure, the interior of the frame 1 of the switchboard is divided into multiple compartments by the fixed partition plate 4. As the multiple compartments, for example, there are a draw-out equipment compartment 100A, a busbar compartment 100B, and a cable compartment 100C. Among them, the draw-out equipment compartment 100A is a defined area that houses draw-out equipment 2 such as a circuit breaker (vacuum circuit breaker), the busbar compartment 100B is a defined area that houses the three-phase (R-phase, S-phase, T-phase) busbars 5, and the cable compartment 100C is a defined area that houses the cables 6 of the external lines. In addition, in this application, the busbar compartment 100B and the cable compartment 100C are referred to as the high-voltage compartment 100D. In addition, although not shown in the figure, there is a control compartment for accommodating control equipment.

[0011] In the draw-out equipment compartment 100A, the draw-out fixing frame 3 is provided in two layers, for example, and draw-out equipment 2 such as a circuit breaker is respectively arranged on the draw-out fixing frame 3. In addition, since the internal structure of the draw-out equipment 2 such as a circuit breaker is well-known, the illustration thereof is omitted. In the busbar compartment 100B, three-phase (R-phase, S-phase, T-phase) busbars 5 are arranged, and each busbar 5 is electrically connected to the fixed terminal 10 installed on the bushing 7 through a terminal. In the cable compartment 100C, three-phase (R-phase, S-phase, T-phase) busbars 6 are arranged, and each busbar 6 is electrically connected to the fixed terminal 10 installed on the bushing 7 through a terminal. In Figure 1 In the reference figure, the fixed partition plate 4 is fixed to the frame 1 of the switchboard and divides the draw-out equipment compartment 100A and the high-voltage compartment 100D (the busbar compartment 100B and the cable compartment 100C). The bushing 7 is installed on the fixed partition plate 4, and a fixed terminal 10 that engages with the main circuit terminal (not shown) of the draw-out equipment 2 is installed through the bushing 7. The bushing 7 functions to insulate the high-voltage live part, that is, the fixed terminal 10, from the grounding part. The bushing 7 is provided with an opening on the side closer to the draw-out equipment compartment 100A, and the opening is used for the fixed terminal 10 and the main circuit terminal (not shown) of the draw-out equipment 2 to engage. In order to ensure the reliability of the operators, in the state where the draw-out equipment 2 is pulled out, the opening of the bushing 7 is closed by the baffle 12. If the draw-out equipment 2 is inserted, the baffle 12 moves in the vertical direction in conjunction with the movement of the draw-out equipment 2 to open the opening of the bushing 7. Thus, when the draw-out equipment 2 is inserted, the main circuit terminal (not shown) of the draw-out equipment 2 can be engaged with the fixed terminal 10.

[0012] [Description of the Embodiment of the Present Application] Next, according to the drawings, the switchboard of the embodiment of the present application will be described. Figure 2is a side cross-sectional view showing the internal structure of the switchboard according to the embodiment, and is a side cross-sectional view showing the inside of the drawer-type equipment compartment 100A and the high-voltage compartment 100D. In addition, Figure 2 is a cross-sectional view when the drawer-type equipment 2 is inserted. As Figure 2 shown, a conductive partition 20 made of metal or the like that divides the two compartments is provided between the drawer-type equipment compartment 100A and the high-voltage compartment 100D. Different from the case where the reference partition 4 is fixed to the frame 1 of the switchboard as shown in the reference drawing, that is, Figure 1 the partition 20 is arranged in the switchboard so as to be movable in two directions, that is, toward the drawer-type equipment compartment 100A side and toward the high-voltage compartment 100D side. An opening 20A is provided at least at a position of the partition 20 corresponding to the bushing 7, and the bushing 7 is arranged so as to be able to be inserted into the opening 20A. Different from the case where the reference is fixed to the fixed partition 4 as shown in the reference drawing, that is, Figure 1 the bushing 7 is fixed to the fixing frame 30 mounted on the compartment side wall 110 described later. The bushing 7 is provided with an opening 7A on the drawer-type equipment compartment 100A side, and the opening 7A is used for the fixed terminal 10 and the main circuit terminal 11 of the drawer-type equipment 2 to be engaged.

[0013] In addition, as Figure 2 shown, when the drawer-type equipment 2 is inserted, it is formed in a state where the baffle 50 (the upper baffle 50A and the lower baffle 50B) opens the opening 7A of the bushing 7. In addition, a conductive grounding member 22 made of metal or the like having a shape covering the bushing 7 is mounted on the drawer-type equipment compartment 100A side of the partition 20. The grounding member 22 has an opening 22A for the bushing 7 to be inserted at least at a position corresponding to the bushing 7.

[0014] Figure 6 is a front view showing the state where the bushing according to the embodiment is fixed to the fixing frame, and is a front view of the bushing 7 observed from the drawer-type equipment compartment 100A side. Figure 6 In, the fixing frame 30 is mounted on the compartment side wall 110, and the bushing 7 is mounted on the fixing frame 30. As described above, the bushing 7 is provided with an opening 7A on the drawer-type equipment compartment 100A side, and the opening 7A is used for the fixed terminal 10 and the main circuit terminal 11 of the drawer-type equipment 2 to be engaged. In addition, in the figure, 120 is the compartment top plate, and 130 is the compartment bottom plate.

[0015] Figure 3 With Figure 2Also a side cross-sectional view showing the internal structure of the switchboard representing the embodiment, which is a side cross-sectional view showing the inside of the drawer-type equipment compartment 100A and the high-voltage compartment 100D. In addition, Figure 3 It is a cross-sectional view when the drawer-type equipment 2 is pulled out. As Figure 3 shown, when the drawer-type equipment 2 is pulled out, the partition plate 20 moves to the pulled-out position, forming a baffle 50 (the upper baffle 50A and the lower baffle 50B) in a state of closing the opening 7A of the bushing 7 in a covering manner. At this time, the grounding member 22 moves together with the movement of the partition plate 20 to a position closer to the drawer-type equipment compartment 100A side than the position in the inserted state of the Figure 2 drawer-type equipment 2, that is, it moves to the Figure 3 left side.

[0016] As described above, in this embodiment, the bushing 7 is not fixed to the partition plate 20, and the partition plate 20 is arranged to be movable in two directions, namely, to the drawer-type equipment compartment 100A side and to the high-voltage compartment 100D side, relative to the bushing 7 fixed to the fixing frame 30. That is, when the drawer-type equipment 2 is inserted as Figure 2 shown, compared with when the drawer-type equipment 2 is pulled out as Figure 3 shown, the partition plate 20 moves to a position on the high-voltage compartment 100D side ( Figure 2 right side) relative to the bushing 7.

[0017] As described above, a baffle 50 (the upper baffle 50A and the lower baffle 50B) is provided. When the drawer-type equipment 2 is inserted, the baffle 50 opens the opening 22A of the grounding member 22, and as Figure 3 shown, when the drawer-type equipment 2 is pulled out, the baffle 50 covers the opening 22A of the grounding member 22. That is, as Figure 2 shown, when the drawer-type equipment 2 is inserted, the upper baffle 50A moves upward and the lower baffle 50B moves downward, thereby opening the opening 7A of the bushing 7.

[0018] In this embodiment, as Figure 2 shown, when the drawer-type equipment 2 is inserted, since the partition plate 20 and the grounding member 22 move to the high-voltage compartment 100D side, a predetermined creepage insulation distance LA can be ensured between the main circuit terminal 11 of the drawer-type equipment 2 and the grounding member 22. In this way, since a predetermined creepage insulation distance can be ensured between the main circuit terminal 11 of the drawer-type equipment 2 and the grounding member 22, the reliability of the operator can be ensured when the drawer-type equipment 2 is inserted.

[0019] On the other hand, in the present embodiment, as Figure 3 shown, when the pull-out device 2 is pulled out, since the partition plate 20 and the grounding member 22 move toward the pull-out device compartment 100A side, the distance LB between the grounding member 22 and the baffle plates 50 (the upper baffle plate 50A and the lower baffle plate 50B) can be shortened.

[0020] Figure 4 And Figure 5 are diagrams for explaining the mechanism for moving the partition plate of the embodiment. Figure 4 is a diagram when the pull-out device 2 is inserted, and is a diagram viewed from the A-A line of Figure 2 . Figure 5 is a diagram when the pull-out device 2 is inserted, and is a diagram viewed from the B-B line of Figure 3 . In the present embodiment, as a means for moving the partition plate 20, a link 25 for driving the partition plate and a return spring 26 are provided, and the pull-out device 2 is configured to be moved by using them.

[0021] As Figure 4 and Figure 5 shown, the link 25 for driving the partition plate is mounted on the partition plate 20. In addition, a return spring 26 is provided between the link 25 for driving the partition plate and a fixing portion 27 fixed to the side wall 110 of the compartment. As Figure 4 shown, when the pull-out device 2 is inserted, since the pull-out device 2 presses the link 25 for driving the partition plate, the partition plate 20 can be moved to the insertion position (the position when the pull-out device 2 is inserted and the fixed terminal 10 is engaged with the main circuit terminal 11). On the other hand, as Figure 5 shown, in the case of pulling out the pull-out device 2, along with the movement of the pull-out device 2, under the action of the force of the return spring 26, the partition plate 20 returns to the position before being pressed by the pull-out device 2, that is, returns to the pull-out position. Here, although it returns to the pull-out position under the action of the return spring 26, the partition plate 20 may also return to the pull-out position by other means.

[0022] Figure 7 And Figure 8 are front views showing the drive mechanism of the partition plate and the baffle plate of the embodiment. Figure 7 is when Figure 2 shown, the pull-out device 2 is inserted, and is a front view observed from the side of the pull-out device 2 ( Figure 2 the left side), and is a view observed in the state where the pull-out device 2 is removed. Figure 8 is when Figure 3The front view observed from one side ( Figure 3 the left side) of the pull-out device 2 when the pull-out device 2 is pulled out is a view observed in a state where the pull-out device 2 is removed. As Figure 7 and Figure 8 shown, partition driving guides 21 are respectively provided at the upper and lower parts of the partition plate 20. Tracks (not shown) are provided at positions of the compartment side wall 110 corresponding to the partition driving guides 21, and the tracks extend in the direction in which the pull-out device 2 is inserted and pulled out. The partition driving guides 21 are guided by the tracks so that the partition plate 20 can move. Here, guides are provided at four positions respectively at the upper and lower parts of the partition plate 20, but they may also be provided only at the upper part, and the number is not particularly limited. In addition, the tracks may be provided on one side of the compartment top plate 120 and one side of the compartment bottom plate 130.

[0023] The baffle 50 is driven in the vertical direction by engaging with the pull-out device 2 and the baffle driving link portion in accordance with the movement of the pull-out device 2. Here, as described later, the upper baffle 50A converts the downward movement of the baffle driving link into an upward movement through the link rotation shaft 52A of the baffle driving link, but the implementation manner is not limited as long as the baffle 50 can be driven in the vertical direction.

[0024] As Figure 7 and Figure 8 shown, a baffle driving link portion for driving the baffle 50 described below is provided at positions corresponding to the side and lower parts of the partition plate 20. The baffle driving link portion for driving the upper baffle 50A includes a first baffle driving link 51, a second baffle driving link 52, and a third baffle driving link 53. The first baffle driving link 51 is provided at the side portion of the partition plate 20 to move in the vertical direction. Along with the vertical movement of the first baffle driving link 51, the upper baffle 50A coupled to the first baffle driving link 51 moves in the vertical direction. The second baffle driving link 52 is mounted on the partition plate 20 so as to rotate about the link rotation shaft 52A, one end is connected to the first baffle driving link 51, and the other end is connected to the third baffle driving link 53. A hole portion is provided at the other end of the second baffle driving link 52, and the front end of the third baffle driving link 53 is inserted into the hole portion, so that the other end of the second baffle driving link 52 and the third baffle driving link 53 are connected together. As described later Figure 9As shown, the third baffle drive link 53 extends from a position on the side of the partition plate 20 closer to the pull-out device 2 towards the partition plate 20. One end is connected to the other end of the second baffle drive link 52 as described above, and the other end is rotatably mounted in a manner that rotates about a rotating shaft 53A provided on the compartment bottom plate 130 (here, provided on the compartment bottom plate, but may also be provided on the compartment side wall). The third baffle drive link 53 is arranged to be inclined at a preset angle θ with respect to the compartment bottom plate 130 in a state where the pull-out device 2 is pulled out.

[0025] The baffle drive link portion for driving the lower baffle 50B includes a fourth baffle drive link 54, a fifth baffle drive link 55, and a sixth baffle drive link 56. The sixth baffle drive link 56 is arranged to move in the vertical direction at the side of the partition plate 20. Along with the vertical movement of the sixth baffle drive link 56, the lower baffle 50B coupled to the sixth baffle drive link 56 moves in the vertical direction. One end of the fifth baffle drive link 55 is connected to the sixth baffle drive link 56, and the other end is connected to the fourth baffle drive link 54. As described later Figure 9 As shown, the fourth baffle drive link 54 extends from a position on the side of the partition plate 20 closer to the pull-out device 2 towards the partition plate 20. One end is connected to the other end of the fifth baffle drive link 55 as described above, and the other end is rotatably mounted in a manner that rotates about a rotating shaft 54A provided on the compartment bottom plate 130 (here, provided on the compartment bottom plate, but may also be provided on the compartment side wall). The fourth baffle drive link 54 is arranged to be inclined at a preset angle θ with respect to the compartment bottom plate 130 in a state where the pull-out device 2 is pulled out.

[0026] Figures 9 to 12 It is a diagram for explaining the operation of the baffle in the embodiment. Figure 9 It is a side view of the interior of the compartment showing the state where the pull-out device 2 is pulled out, Figure 10 It is also a front view observed from the side of the pull-out device compartment 100A showing the state where the pull-out device 2 is pulled out. Figure 11 It is a side view of the interior of the compartment showing the state where the pull-out device 2 is inserted, Figure 12 It is also a front view observed from the side of the pull-out device compartment 100A showing the state where the pull-out device 2 is inserted. In addition, Figures 9 to 12 For explaining the operation of the baffle, the baffle and the baffle drive link are mainly shown, and other components are appropriately omitted.

[0027] As shown in the figure, one end side of the third baffle driving link 53 and the fourth baffle driving link 54 engages with the bottom of the pull-out device 2 when the pull-out device 2 is inserted. In addition, when the pull-out device 2 is inserted, the third baffle driving link 53 and the fourth baffle driving link 54 rotate about the rotating shafts 53A and 54A provided on one side of the compartment bottom plate 130 as pivots and move toward the compartment bottom plate 130 side. That is, when the pull-out device 2 is inserted, the bottom of the pull-out device 2 contacts the third baffle driving link 53 and the fourth baffle driving link 54, and thus moves on the third baffle driving link 53 and the fourth baffle driving link 54. The third baffle driving link 53 and the fourth baffle driving link 54 are installed in a manner that they can rotate about the rotating shafts 53A and 54A. Therefore, as the pull-out device 2 moves, the third baffle driving link 53 and the fourth baffle driving link 54 are pushed against the bottom of the pull-out device 2 and rotate about the rotating shafts 53A and 54A, and the other end sides of the third baffle driving link 53 and the fourth baffle driving link 54 move toward the compartment bottom plate 130 side.

[0028] Next, the operation of the upper baffle 50A will be described. Since a force is generated under the action of the third baffle driving link 53 to push the other end of the second baffle driving link 52 toward the compartment bottom plate 130 side, the other end of the second baffle driving link 52 also moves downward, that is, the second baffle driving link 52 rotates clockwise about the link rotating shaft 52A. Figure 10 In addition, although the other end of the third baffle driving link 53 is inserted into the hole of the second baffle driving link 52, it is only supported and not fixed. Therefore, as the third baffle driving link 53 rotates, the second baffle driving link 52 can move toward the compartment bottom plate 130 side.

[0029] In the state where the pull-out device 2 is pulled out, as Figure 10 shown, the upper baffle 50A covers the opening 7A of the sleeve 7. When the pull-out device 2 is inserted, as described above, the third baffle driving link 53 engages with the pull-out device 2, and the third baffle driving link 53 is driven toward the compartment bottom plate 130 side. When the third baffle driving link 53 moves toward the compartment bottom plate 130 side, the second baffle driving link 52 rotates about the link rotating shaft 52A as a pivot. When the second baffle driving link 52 rotates, the first baffle driving link 51 connected to the second baffle driving link 52 moves toward the compartment top plate 120 side. Since the upper baffle 50A is fixed to the first baffle driving link 51, as Figure 12 shown, the upper baffle 50A moves upward in conjunction with the movement of the first baffle driving link 51, thereby opening the opening 7A of the sleeve 7. In addition, when the drawer-type device 2 is pulled out, under the action of a return spring (not shown), the upper baffle 50A returns to cover the opening 7A of the sleeve 7.

[0030] Next, the operation of the lower baffle 50B will be described. Since a force is generated by the fourth baffle drive link 54 to push the other end of the fifth baffle drive link 55 toward the compartment bottom plate 130, the other end of the fifth baffle drive link 55 also moves downward. In the state where the drawer-type device 2 is pulled out, as Figure 10 shown, the lower baffle 50B covers the opening 7A of the sleeve 7. When the drawer-type device 2 is inserted, as described above, the fourth baffle drive link 54 engages with the drawer-type device 2, and the fourth baffle drive link 54 is driven toward the compartment bottom plate 130. When the fourth baffle drive link 54 moves toward the compartment bottom plate 130, the fifth baffle drive link 55 connected to the fourth baffle drive link 54 moves toward the compartment bottom plate 130. In addition, the sixth baffle drive link 56 connected to the fifth baffle drive link 55 also moves toward the compartment bottom plate 130. Since the lower baffle 50B is fixed to the sixth baffle drive link 56, as Figure 12 shown, the lower baffle 50B moves downward in conjunction with the movement of the sixth baffle drive link 56, thereby opening the opening 7A of the sleeve 7. In addition, when the drawer-type device 2 is pulled out, under the action of a return spring (not shown), the lower baffle 50B returns to cover the opening 7A of the sleeve 7.

[0031] In the foregoing description, the link rotation shaft 52A, the first baffle drive link 51, and the sixth baffle drive link are configured to be installed on the partition plate 20 and cooperate with the movement of the drawer-type device 2 to drive the baffle 50. However, the link rotation shaft 52A, the first baffle drive link 51, and the sixth baffle drive link 56 may be installed on a part other than the partition plate 20, and a structure that drives the baffle 50 without cooperating with the movement of the drawer-type device 2.

[0032] As described above, according to the present embodiment, in a distribution board for accommodating a drawer-type device, it includes: a conductive partition plate that divides a high-voltage compartment in the distribution board and a drawer-type device compartment for accommodating the drawer-type device, and can move to a pulled-out position and an inserted position in conjunction with the pulling-out action and the inserting action of the drawer-type device; and a sleeve that is fixed to a fixing frame provided on the frame of the distribution board and is provided with fixing terminals for engaging with the main circuit terminals of the drawer-type device Therefore, it is possible to provide a distribution board that can suppress the number of components, is easy to assemble, and ensures reliability.

[0033] The distribution board includes a conductive grounding member disposed on the side of the partition plate closer to the draw-out equipment compartment and covering the outer periphery of the bushing when the draw-out equipment is pulled out. Therefore, it is possible to provide a distribution board with ensured reliability.

[0034] In addition, when the draw-out equipment is inserted, since the partition plate and the grounding member move toward the high-voltage compartment side, a preset creepage insulation distance is ensured between the main circuit terminal of the draw-out equipment and the grounding member. Therefore, the reliability of the operator can be ensured.

[0035] In addition, a guide for driving the partition plate is provided on the partition plate, and a track for guiding the guide for driving the partition plate is provided on the frame of the distribution board. Therefore, the partition plate can move smoothly.

[0036] In addition, a link for driving the partition plate is installed on the partition plate, and a return spring is provided between the link for driving the partition plate and the frame of the distribution board. When the draw-out equipment is inserted, the draw-out equipment presses the link for driving the partition plate, thereby moving the partition plate to the insertion position. And when the draw-out equipment is pulled out, along with the movement of the draw-out equipment, under the action of the return spring, the partition plate returns to the pull-out position. Therefore, it is possible to move the partition plate in conjunction with the insertion and pull-out of the draw-out equipment with a simple structure.

[0037] In addition, the distribution board includes a baffle that covers the opening of the bushing when the draw-out equipment is pulled out. Therefore, the reliability of the operator can be ensured.

[0038] In addition, the distribution board includes a grounding member disposed on the side of the partition plate closer to the draw-out equipment compartment and covering the outer periphery of the bushing when the draw-out equipment is pulled out. When the draw-out equipment is pulled out, the distance between the baffle and the grounding member is set to be less than or equal to a predetermined distance. Thereby, the discontinuity of the grounding member at the position where the draw-out equipment is pulled out reaches less than or equal to a predetermined distance, and the reliability of the operator can be further ensured.

[0039] In addition, a baffle driving link portion is provided on the baffle. Under the action of the baffle driving link part, when the pull-out device is inserted, the baffle opens the opening of the sleeve, and when the pull-out device is pulled out, the baffle closes the opening of the sleeve. Therefore, with a simple structure, the baffle can open and close the opening of the sleeve in conjunction with the insertion and withdrawal of the pull-out device.
