Description

[Technical field]

[0001] This application relates to a control center. [Background technology]

[0002] Conventionally, an operating handle mechanism has been proposed that has a mechanism for turning a molded case circuit breaker on / off in synchronization with the ON / OFF of an operating handle, and a mechanism for moving an interlock rod up and down (see, for example, Patent Document 1). In this document, the interlock rod retracts when the operating handle is OFF, and protrudes when the operating handle is ON.

[0003] With the control device mounted on the panel, when the operating handle is turned from OFF to ON, the interlock rod passes through an engagement portion provided on a partition plate inside the control center housing and is fixed to the control center housing.

[0004] On the other hand, if an attempt is made to store the control device in the control center housing with the operating handle in the ON position, the interlock rod protruding upward from the control device will interfere with the partition plate, preventing the control device from being stored in this state.

[0005] Such an interlock rod mechanism can prevent the following erroneous operations. First, it is possible to prevent the control device from being mounted on the panel while the molded case circuit breaker is in the ON state. Next, it is possible to prevent the mounted control device from being pulled out from the panel while the molded case circuit breaker is in the ON state. [Prior art documents] [Patent documents]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Embodiment 1 The control center according to the first embodiment will be described below with reference to the drawings. FIG. 1 is a perspective view of a control center 100. The control center 100 comprises a control center housing 10 and a number of control devices 20 housed therein. The control center housing 10 is provided with partition plates 30 for separating the respective control devices 20, which divide the internal space into a number of sections vertically.

[0013] Fig. 2 is a perspective view of the control device 20. For convenience of explanation, the front panel has been removed. In Fig. 2, the partition plate 30 of the control center housing 10 is indicated by a dashed line. FIG. 3A is a top view of the partition plate 30 and the control device 20 as viewed from the upper surface side of the partition plate 30. FIG. FIG. 3B is a top view of the control device 20.

[0014] The control device 20 has a contactor 21 that electrically connects the control device 20 to a main bus (not shown) provided in the control center housing 10, a circuit breaker 22 for protecting load equipment (motor, pump, etc.) not shown that is provided below the control device 20, an operating handle 23 for turning the circuit breaker 22 on / off, an interlock rod 24 that moves linearly in the vertical direction in synchronization with the ON / OFF of the operating handle 23, and a latch mechanism 50 that engages with the partition plate 30 of the control center housing 10 in the operating position.

[0015] 4A is an enlarged perspective view of a main part of the control device 20. The control device 20 is stored in the operating position of the control center housing 10, and the latch mechanism 50 is still in the OFF state. 4B is an enlarged perspective view of a main part of the control device 20. The control device 20 is stored in the operating position of the control center housing 10, the latch mechanism 50 is ON, and the operating handle 23 is still OFF. 4C is an enlarged perspective view of a main part of the control device 20. This shows a state in which the control device 20 is stored in the operating position of the control center housing 10, the latch mechanism 50 is ON, and the operating handle 23 is ON.

[0016] The latch mechanism 50 has the function of fixing the control device 20 stored in the operating position of the control center housing 10 to the partition plate 30 of the control center housing 10, and the function of preventing erroneous operation of the operating handle 23 by the operator by enabling the interlock rod 24, which is linked to the ON operation of the operating handle 23, to engage with the partition plate 30 only when the control device 20 is engaged with the partition plate 30.

[0017] 5 to 7 are perspective views of the latch mechanism 50 (excluding the rotation shaft), each viewed from a different direction. The latch plate 51 of the latch mechanism 50 consists of a flat plate perpendicular to the storage direction Y of the control device 20 shown in Figures 1 and 2, and has a partition plate engagement portion 51A that engages with the latch mechanism engagement hole 30RH (latch mechanism engagement portion) of the partition plate 30 of the control center housing 10 shown in Figure 3A.

[0018] The interlock rod control section 51B is connected perpendicularly to the latch plate 51, and controls the passage / stop of the interlock rod 24 by the rotation of the latch plate 51 about a rotation axis O parallel to the storage direction Y of the control device 20 (controls whether the interlock rod 24 can be inserted into the interlock rod engagement hole 30IH (interlock rod engagement section) of the partition plate 30). In reality, the latch mechanism 50 of the present embodiment 1 is composed of a single plate.

[0019] In addition, the top plate 25 of the control device 20 shown in Figure 3B has a latch plate through hole 25RH through which the partition plate engagement portion 51A of the latch plate 51 penetrates upward when the latch plate 51 is engaged with the partition plate 30, and an interlock rod through hole 25IH through which the interlock rod 24 penetrates upward when the interlock rod 24 is engaged with the partition plate 30.

[0020] Next, a procedure for storing the control device 20 in the control center housing 10 will be described with reference to FIGS. 4A to 4C and 8A to 13B. 8A is a perspective view of the main part, seen from diagonally above, showing a state in which the control device 20 is stored in the operating position at the rear of the control center housing 10 and the latch mechanism 50 is still OFF. In FIG. 8A, the partition plate 30 of the control center housing 10 is depicted. FIG. 8B is a diagram in which the partition plate 30 is removed from FIG. 8A.

[0021] FIG. 9A is a perspective view of FIG. 8A seen from below. FIG. 9B is a perspective view of FIG. 8B seen from below.

[0022] Fig. 10A is a perspective view of the essential parts seen from diagonally above in a state in which the control device 20 is stored in the operating position at the back of the control center housing 10, the latch mechanism 50 is ON, and the operating handle 23 is still OFF. Fig. 10A illustrates the partition plate 30 of the control center housing 10. FIG. 10B is a diagram in which the partition plate 30 is removed from FIG. 10A.

[0023] FIG. 11A is a perspective view of FIG. 10A seen from below. FIG. 11B is a perspective view of FIG. 10B seen from below.

[0024] Fig. 12A is a perspective view of the essential parts seen from diagonally above in a state in which the control device 20 is stored to the operating position at the back of the control center housing 10, the latch mechanism 50 is ON, and the operating handle 23 is also ON. Fig. 12A illustrates the partition plate 30 of the control center housing 10. FIG. 12B is a diagram in which the partition plate 30 is removed from FIG. 12A.

[0025] FIG. 13A is a perspective view of FIG. 12A seen from below. FIG. 13B is a perspective view of FIG. 12B seen from below.

[0026] 4A, the control device 20 is pushed into and stored in the control center housing 10 with the operating handle 23 in the OFF position and the latch mechanism 50 in the OFF position. When the operating handle 23 is in the OFF position, the interlock rod 24 is in the lowered position.

[0027] In addition, when the latch mechanism 50 shown in FIG. 4A is in the OFF state, the partition plate engagement portion 51A of the latch plate 51 is not engaged with the partition plate 30, and the interlock rod control portion 51B of the latch plate 51 is positioned in a position that prevents the upward movement of the interlock rod 24.

[0028] If an attempt is made to store the control device 20 in the control center housing 10 with the latch mechanism 50 in the ON state, the partition plate engagement portion 51A of the latch plate 51 protrudes above the top plate 25 of the control device 20, causing interference between the partition plate engagement portion 51A and the partition plate 30, and making it impossible to store the control device 20 completely to the operating position at the back of the control center housing 10.

[0029] As shown in Fig. 4B, after the control device 20 is stored to the operating position at the back of the control center housing 10, the partition plate engaging portion 51A of the latch plate 51 is engaged with the partition plate 30 (the partition plate engaging portion 51A is rotated counterclockwise), and in synchronization with this, the interlock rod control portion 51B also rotates counterclockwise, allowing the interlock rod 24 to penetrate upward through the latch mechanism 50. This state is defined as the ON state of the latch mechanism 50. In other words, the operating handle 23 can be turned from OFF to ON only when the latch mechanism 50 is in the ON state.

[0030] As shown in FIG. 4C, when the operating handle 23 is turned ON, the interlock rod 24 moves upward in synchronization with the movement of the operating handle 23 from OFF to ON, and passes upward through the interlock rod through hole 25IH provided in the top plate 25 of the control device 20 to engage with the interlock rod engagement hole 30IH provided in the partition plate 30.

[0031] According to the control center 100 according to the first embodiment, The system comprises a control center housing and a plurality of control devices housed in the control center housing, the control center housing includes a partition plate for separating the control devices from each other; The control device includes an operation handle, a molded-case circuit breaker that is turned on / off in synchronization with the ON / OFF of the operation handle, and an interlock rod that moves linearly in synchronization with the ON / OFF of the operation handle, The control device is provided with a latch mechanism having a latch plate having a partition plate engaging portion engageable with the latch mechanism engaging portion of the control center housing when the control device is stored to the operating position of the control center housing, and an interlock rod control portion that controls the operation of the interlock rod so that the interlock rod can engage with the interlock rod engaging portion of the partition plate only when the partition plate engaging portion of the latch plate is engaged with the latch mechanism engaging portion of the control center housing, The interlock rod control section 51B provided on the latch plate 51 of the latch mechanism 50 determines whether the interlock rod 24 can be inserted into the interlock rod engagement hole 30IH of the partition plate 30 or not. In the conventional case where the passing / stopping control of the interlock rod was controlled by a partition plate provided in the latch mechanism, bending and deformation of the partition plate had to be prevented, otherwise the operating handle could be turned on even in a position where it should not be possible to turn it on, and so it was essential to reinforce the partition plate. However, in the present application, this can be achieved by simply reinforcing the interlock rod control unit 51B provided in the latch plate 51 of the latch mechanism 50.

[0032] Furthermore, even when replacing the control device 20, reinforcement can be completed within the control device 20 alone, without changing the partition plate 30 attached to the control center housing 10.

[0033] In addition, the partition plate engagement portion 51A and the interlock rod control portion 51B of the latch plate 51 are not limited to those according to this embodiment, and the partition plate engagement portion 51A may be configured to engage with a part of the control center housing 10, and the interlock rod control portion 51B may be configured to control the passage / stop of the interlock rod 24 depending on whether or not the control device 20 is engaged with the control center housing 10.

[0034] Further, in the first embodiment, the direction of movement of the interlock rod 24 is the up-down direction of the control device 20, but it may be the left-right direction or the front-rear direction.

[0035] According to the control center 100 according to the first embodiment, The latch mechanism includes the latch plate having a flat shape perpendicular to a direction in which the control device is stored, and the interlock rod control unit perpendicularly connected to the latch plate, Since the latch plate is rotatable about a rotation axis parallel to the storage direction of the control device, the structure of the latch mechanism can be simplified and manufacturing costs can be reduced.

[0036] According to the control center 100 according to the first embodiment, The top plate of the control device has a latch plate through hole through which the partition plate engaging portion of the latch plate penetrates when the latch plate is engaged with the partition plate, and an interlock rod through hole through which the interlock rod penetrates when the interlock rod is engaged with the partition plate, The operating position of the control device 20 inside the control center housing 10 can be accurately determined.

[0037] According to the control center 100 according to the first embodiment, The interlock rod has an L-shaped cross section perpendicular to the longitudinal direction, and the latch mechanism engagement portion is an L-shaped through hole. Although a cylindrical rod is used as the interlock rod 24, the present invention is not limited to this, and the cross section perpendicular to the operating direction may be L-shaped, for example, as shown in Fig. 41B. By making the interlock rod engagement hole 30IH of the partition plate 30 a through-hole of the same L shape as shown in Fig. 41A, the positional relationship between the interlock rod 24 and the interlock rod engagement hole 30IH is determined by the two sides of the L shape, so that it is possible to prevent the control device 20 from being turned from OFF to ON when the control device 20 is inserted at an angle.

[0038] In the first embodiment, a cylindrical rod is used as the interlock rod 24, but a release (mechanical, electromagnetic, etc.) may also be used. For the rod-shaped interlock rod 24, restrictions on the positional relationship between the operating handle 23 and the latch mechanism 50 are relaxed, allowing the latch mechanism 50 to be flexibly positioned.

[0039] Embodiment 2 The control center according to the second embodiment will be described below, focusing on the differences from the first embodiment. Fig. 14 is a perspective view of the control device 220. For convenience of explanation, the front panel has been removed. In Fig. 14, the partition plate 230 of the control center housing 10 is indicated by a dashed line.

[0040] The difference between the first embodiment and the second embodiment is that, whereas in the first embodiment, the control device 20 is provided with one latch mechanism 50 and one interlock rod 24, in the second embodiment, the control device 220 is provided with two latch mechanisms 250A and 250B and two interlock rods 224A and 224B. There is only one operating handle 223, and the two interlock rods 224A and 224B move linearly in synchronization with the ON / OFF operation of the single operating handle.

[0047] After storing the control device 220 to the operating position at the back of the control center housing 10, the latch mechanism 250A and the latch mechanism 250B are turned from OFF to ON. As a result, the partition plate engagement parts 251A1 and 251A2 engage with the latch mechanism engagement holes 230RH1 and 230RH2 of the partition plate 230, the interlock rod control parts 251B1 and 251B2 are opened, and the interlock rods 224A and 224B can move above the control device 220.

[0048] Thereafter, when the operating handle 223 is turned from OFF to ON, in synchronization therewith, the interlock rods 224A, 224B move upwardly of the control device 220, pass through the interlock rod through holes 225IH1, 225IH2 provided in the top plate 225 of the control device 220, and engage with the interlock rod engagement holes 230IH1, 230IH2 provided in the partition plate 230.

[0049] According to the control center according to the second embodiment, At least one of the latch mechanism and the interlock rod is provided in plurality. By providing two latch mechanisms 250A, 250B and two interlock rods 224A, 224B, redundancy for each can be ensured.

[0050] Furthermore, since the control device 220 and the partition plate 230 engage with each other in a plurality of positions, it is possible to prevent the operating handle 23 from being turned from OFF to ON when the control device 20 is stored at an angle. In addition, since the force transmitted to the interlock rods 224A and 224B can be reduced by half, the reinforcement of the interlock rod control section can be simplified (for example, the plate thickness can be made thinner than in the case of claim 1), which leads to cost reduction.

[0051] In the second embodiment, two latch mechanisms and two interlock rods are provided, but either one may be provided alone. In addition, it is acceptable for three or more latch mechanisms and interlock rods to be provided. For example, FIG. 21 is a diagram showing another example of a control device, and is a front view of the control device including one latch mechanism 250A and two interlock rods 224A, 224B.

[0052] Embodiment 3 The control center according to the third embodiment will be described below, focusing on the differences from the first embodiment. Fig. 22 is a perspective view of the control device 320. For convenience of explanation, the front panel has been removed. In Fig. 22, the partition plate 330 of the control center housing 10 is indicated by a dashed line. FIG. 23A is a top view of the partition plate 330 of the control center housing 10. FIG. FIG. 23B is a perspective view of the partition plate 330 of the control center housing 10. FIG. FIG. 23C is a top view of the top plate 325 of the control device 320. FIG. FIG. 23D is a perspective view of top plate 325 of control device 320.

[0053] FIG. 24A is a perspective view of a main part showing an operating state of the control device 320. FIG. 24B is a diagram showing a state in which the latch mechanism 350 is turned ON and the operating handle 23 is turned ON when the control device 320 is in the operating position. The partition plate 330 of the control center housing 10 is also illustrated. FIG. 25A is a perspective view of a main part showing a transition state of control device 320. FIG. 25B is a diagram showing a state in which the latch mechanism 350 of the control device 320 is switched to the test position, the operating handle 23 is turned OFF, and the control device 320 is pulled out to the test position. The partition plate 330 of the control center housing 10 is also illustrated. FIG. 26A is a perspective view of a main part showing a test position of the control device 320. FIG. 26B is a diagram showing the state where the latch mechanism 350 is ON and the operating handle 23 is OFF in the test position of the control device 320. The partition plate 330 of the control center housing 10 is also shown. In the test position, the circuit of the control device 320 can be tested with the control device 320 disconnected from the main busbar. FIG. 27A is a perspective view of the main part showing a state in which the control device 320 is pulled out from the control center housing 10. FIG. 27B is a diagram showing the state of the latch mechanism 350 and the interlock rod 324 when the control device 320 is pulled out from the control center housing 10 and when it is stored to the operating position. The partition plate 330 of the control center housing 10 is also illustrated.

[0054] The difference between this embodiment 3 and embodiment 1 is that the latch mechanism 350 of the control device 320 and the partition plate 330 of the control center housing 10 have a mechanism for controlling the storage position of the control device 320 within the control center housing 10 and the function at each position.

[0055] That is, (1) In the operating position of the control device 320 shown in FIGS. 24A and 24B, the operating handle 23 can be turned ON by turning the latch mechanism 350 ON. (2) As shown in Figures 25A and 25B, by placing the latch mechanism 350 in the test position and turning the operating handle 23 OFF, the control device 320 can be moved from the operating position to the test position, and vice versa. In this case, the interlock rod 324 interferes with the interlock rod control section 351B, so that the operating handle 23 cannot be turned ON. (3) As shown in Figures 26A and 26B, the position of control device 320 can be fixed by moving control device 320 to the test position and turning on latch mechanism 350. Note that in this position, even if an attempt is made to turn operating handle 23 on, it cannot be turned on because interlock rod 324 interferes with top plate 325 of control device 320. (4) As shown in Figures 27A and 27B, by setting the latch mechanism 350 to the OFF position, the control device 320 can be moved to the operating position or the control device 320 can be completely pulled out from the control center housing 10. When the latch mechanism 350 is in the OFF state, the control device 320 can be moved, but the operating handle 23 cannot be turned ON.

[0056] FIG. 29 is a perspective view of the latch mechanism 350. FIG. 30 is a perspective view of the latch mechanism 350. FIG. 31 is a perspective view of the latch mechanism 350. The latch mechanism 350 includes a latch plate 351 having a partition plate engaging portion 351A that engages with the partition plate 330 of the control center housing 10 and an operating position-test position transition portion 351C that allows the control device 320 housed in the control center housing 10 to move only between the operating position and the test position, and an interlock rod control portion 351B that controls the passing / stopping of the interlock rod 324. 22 of the control device 320, and the latch plate 351 is rotatable about a rotation axis O parallel to the storage direction Y of the control device 320. The interlock rod control unit 351B has a plate with a U-shaped cross section fixed to the rotation axis O perpendicular to the latch plate 351.

[0057] 23A and 23B, the partition plate 330 has a latch mechanism engagement hole 330RH that engages with the partition plate engagement portion 351A of the latch mechanism 350 when the control device 320 is in the operating position, a latch mechanism test position engagement hole 330RHT (latch mechanism test position engagement portion) that engages with the partition plate engagement portion 351A when the control device 320 is in the test position, and a partition plate protrusion 330P that protrudes upward from the plate surface of the partition plate 330, protruding from the control device 320 toward the control center housing 10 side and through which only the operating position-test position transition portion 351C of the latch plate 351 can pass back and forth when the control device 320 is moved between the operating state position and the test position. The latch mechanism engagement hole 330RH and the latch mechanism test position engagement hole 330RHT are connected by a space formed below the partition plate protrusion 330P.

[0058] As shown in Figures 23C and 23D, the top plate 325 of the control device 320 has a latch plate through hole 325RH through which the partition plate engagement portion 351A and the operating position-test position transition portion 351C of the latch plate 351 can pass vertically, and a through hole 325H3 that combines the function of the interlock rod through hole 25IH in embodiment 1 and the function of preventing interference when the interlock rod control portion 351B rotates.

[0068] FIG. 40A is a perspective view of FIG. 39A seen from below. FIG. 40B is a perspective view of FIG. 39B seen from below.

[0069] (1) Storage of the control device 320 To store the control device 320 in the control center housing 10, the control device 320 is pushed into the operating position at the back of the control center housing 10 with the operation handle 23 in the OFF state and the latch mechanism 350 in the OFF state, as shown in Figures 27A, 27B, 31A, 31B, 32A, and 32B. When the operation handle 23 is in the OFF state, the interlock rod 324 is in a lowered state. When the latch mechanism 350 is in the OFF state, the partition plate engagement portion 351A of the latch plate 351 is not engaged with the partition plate 330. In addition, the interlock rod control portion 351B is located in a position that prevents the upward movement of the interlock rod 324.

[0070] (2) Put the control device 320 into operation. After storing the control device 320 in the control center housing 10, as shown in Figures 24A, 24B, 33A, 33B, 34A and 34B, the partition plate engagement portion 351A of the latch mechanism 350 is inserted upward through the latch plate through hole 325RH of the top plate 325 and then engaged with the latch mechanism engagement hole 330RH of the partition plate 330 (in Figure 31A, the partition plate engagement portion 351A is rotated 180 degrees clockwise), and in synchronization with this, the interlock rod control portion 351B also rotates 180 degrees clockwise, and the restriction on upward movement of the interlock rod 324 is released.

[0071] When the operating handle 23 is turned ON from this state (FIGS. 33A to 34B), the state changes to that shown in FIGS. 35A to 36B, and the interlock rod 324 passes upward through the through-hole 325H3 of the top plate 325 and further engages with the interlock rod engaging hole 330IH of the partition plate 330.

[0072] The contactor 21 of the control device 320 is connected to the main bus when the control device 320 is stored in the operating position at the back of the control center housing 10, and by going through the above procedure and turning the operating handle 23 to ON, power can be supplied from the main bus to the load.

[0073] Next, a test procedure for the control device 320 will be described. (1) Suspension of operation First, the operating handle 23 is turned OFF to stop the operation of the control device 320. Accordingly, the engagement between the interlock rod 324 and the partition plate 330 is released. (2) The controller 320 is extended from the operating position to the test position. In order to test the control circuit mounted in the control device 320, it is necessary to disconnect the contactor 21 from the main bus. To do this, the control device 320 is pulled out from the operating position to the test position. By pulling out the control device 320, the contactor 21 is disconnected from the main bus.

[0074] Next, the partition plate engagement portion 51A of the latch mechanism is rotated counterclockwise by 90 degrees, whereby the relationship between the partition plate 330 and the latch plate 351 becomes as shown in Figures 25A, 25B, and 37A to 38B. 37B, operating position-test position transition portion 351C of latch plate 351 protrudes above the top plate of control device 320. When control device 320 is pulled out toward the front in this state, operating position-test position transition portion 351C of latch plate 351 passes along the lower surface of partition plate protrusion 330P and stops by hitting the front edge of latch mechanism test position engagement hole 330RHT of partition plate 330.

[0075] 26A, 26B, and 39A to 40B, the partition plate engagement portion 51A engages with the latch mechanism test position engagement hole 330RHT, and the control device 320 is positioned at the test position. By drawing out the control device 320, the contactor 21 is disconnected from the main busbar, so that the control circuit of the control device 320 can be tested in a safe state where the contactor 21 and the main busbar are disconnected.

[0076] It should be noted that the control device 320 can be returned from the test position to the operation position by reversing this order. In either position, the control device 320 can be completely withdrawn by turning off the latch mechanism 350.

[0077] Partition plate protrusion 330P is shaped so that partition plate engagement portion 51A cannot pass through it. When operating position-testing position transition portion 351C is protruding above top plate 325 of control device 320, it can pass back and forth under the partition plate protrusion to move between the test position and operating position of control device 320, but control device 320 cannot be completely pulled out.

[0078] According to the control center according to the third embodiment, the partition plate further has the latch mechanism engaging portion, a latch mechanism test position engaging portion that engages with the partition plate engaging portion when the control device is in a test position, and a partition plate protruding portion that protrudes from a plate surface of the partition plate and protrudes from the control device toward the control center housing side when the control device is moved between the driving position and the test position, and under which only the driving position-test position transition portion of the latch plate can pass back and forth; The latch mechanism engaging portion and the latch mechanism test position engaging portion are connected by a space formed below the partition plate protrusion, It is possible to combine a latch mechanism 350 for controlling the storage position of the control device 320 with an interlock rod control section 351B for controlling the ON / OFF of the operating handle 23. This allows the operating handle 23 to be turned ON only when the control device 320 is in the storage position.

[0079] According to the control center according to the third embodiment, The latch plate of the latch mechanism is a flat plate perpendicular to the storage direction of the control device, The latch plate is rotatable about a rotation axis parallel to a storage direction of the control device, The latch plate includes the partition plate engagement portion and the operating position-test position transition portion, and the interlock rod control portion includes a U-shaped cross-section plate fixed to the rotation shaft perpendicular to the latch plate, It is possible to combine a latch mechanism for controlling the storage position of the control device 320 with an interlock rod control section 351B that controls the ON / OFF of the operating handle 23. This makes it possible to reduce the number of parts and improve storage efficiency.
