Description

Technical Field

[0001] The present invention relates to the technical field of capacitor energy storage device assembly, in particular to a quick-assembly series capacitor energy storage device and an assembling method thereof. Background Art

[0002] Currently, series capacitors are typically assembled and fixed using a metal frame structure. The individual series capacitors are centrally mounted within the metal frame and transported to the installation site, making installation relatively simple. However, this installation method has some drawbacks and inconveniences. For example, in traditional series compensation technology, the capacity selection of the series fixed capacitors is critical. If the load increases rapidly, the capacity needs to be re-verified, which makes installation and replacement inconvenient.

[0003] In addition, although the external fuse method facilitates fault detection, the installation size is large; while the internal fuse method, although compact in structure, has a protection dead zone that may cause short-circuit faults. These factors may increase the complexity of installation and maintenance in actual applications. Summary of the Invention

[0004] The object of the present invention is to provide a quick-assembly series capacitor energy storage device and an assembly method thereof, so as to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A quick-assembly series capacitor energy storage device comprises: a cabinet, wherein a plurality of plug-in cabinets are arranged in the cabinet, and capacitor devices are detachably installed in the plug-in cabinets;

[0007] A positioning locking mechanism is provided in the plug-in cabinet, and the positioning locking mechanism includes a trigger assembly and a connection assembly. The trigger assembly includes a trigger member elastically slidably provided in the plug-in cabinet, and the connection assembly includes two groups of electrode sheets symmetrically provided along the length direction of the plug-in cabinet, and each group of electrode sheets is fixedly provided with a transverse movement structure;

[0008] During the process of inserting the capacitor device into the plug-in cabinet, the capacitor device can push the trigger member to retract into the plug-in cabinet, and during the retraction of the trigger member, the trigger member cooperates with the transverse movement structure to drive the two groups of electrode sheets to approach each other and lock the capacitor device;

[0009] An unlocking component is also provided in the plug-in cabinet, and the unlocking component can drive the two groups of electrode sheets to move away from each other.

[0010] The quick-assembly series-type capacitor energy storage device as described above: the trigger component includes a sliding rod fixedly arranged in the plug-in cabinet, and the sliding rods are symmetrically arranged in two groups along the length direction of the plug-in cabinet. A first spring is sleeved on the two groups of sliding rods, and one end of the first spring abuts against the cabinet, and the other end abuts against a push plate slidably arranged on the two groups of sliding rods.

[0011] As described above, the quick-assembly series capacitor energy storage device: the trigger member includes a fixing plate fixedly arranged on the pushing plate, and the fixing plates are symmetrically arranged in two groups along the length direction of the pushing plate, and both groups of fixing plates are fixedly provided with protruding columns.

[0012] The quick-assembly series-type capacitor energy storage device as described above: the transverse movement structure includes a transverse movement plate fixedly connected to the electrode sheet, a composite groove is provided on the transverse movement plate, and the protruding column is slidably arranged in the composite groove. When the pushing plate slides relative to the plug-in cabinet, the protruding column cooperates with the composite groove to drive the electrode sheet to slide along the length direction of the plug-in cabinet.

[0013] As described above, the quick-assembly series capacitor energy storage device: the composite slot includes a vertical slot opened on the transverse plate, the ends of the vertical slot are connected to an oblique slot and a horizontal slot, the horizontal slot and the oblique slot are connected by a reset slot, and the connection between the oblique slot and the vertical slot and the reset slot is respectively provided with a first guide member and a second guide member.

[0014] As described above, the quick-assembly series capacitor energy storage device: the first guide member includes a first deflection plate rotatably mounted at the connection between the inclined slot and the vertical slot, and the first deflection plate is elastically connected to the transverse plate via a first elastic sheet.

[0015] As described above, the quick-assembly series capacitor energy storage device: the second guide member includes a second deflection plate rotatably mounted at the connection between the inclined slot and the reset slot, and the second deflection plate is elastically connected to the transverse plate via a second elastic sheet.

[0016] As described above, the quick-assembly series-type capacitor energy storage device: the unlocking component includes a trigger block slidably arranged on the cabinet, and two groups of unlocking blocks are symmetrically fixed on the trigger block. The two groups of unlocking blocks cooperate with the wedge blocks fixedly arranged on the two groups of transverse plates to drive the two groups of electrode sheets away from each other.

[0017] As described above, the quick-assembly series capacitor energy storage device: guide blocks are fixedly provided on the left and right side walls of the plug-in cabinet, and arc guide surfaces are provided on both sets of the guide blocks.

[0018] A method for assembling a fast-assembly series capacitor energy storage device is also proposed, comprising the following steps:

[0019] Step 1: In the initial state, the two sets of electrode sheets are away from each other, and the push plate is close to the cabinet door;

[0020] When assembling the capacitor device, insert the capacitor device into the plug-in cabinet. When inserting, the guide block will align the capacitor device so that the capacitor device is in the center of the plug-in cabinet.

[0021] Step 2: When the capacitor device contacts the push plate, the push plate retracts, causing the protrusion to slide in the vertical slot until the capacitor device passes over the electrode sheet. The capacitor device is then pushed further, and the protrusion cooperates with the inclined slot to force the two sets of electrode sheets closer together. When the capacitor device cannot be pushed any further, the capacitor device is released, and the first spring pushes the capacitor device to move a certain distance.

[0022] Step 3: During this process, the protrusion slides along the reset groove until the protrusion cannot move, and the capacitor device is connected to the electrode sheet;

[0023] Step 4: When disassembling the capacitor device, press the trigger block inward. The unlocking block cooperates with the wedge block to force the two sets of electrode sheets away from each other. At the same time, with the cooperation of the push plate, the capacitor device will automatically protrude outward.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] By setting the guide block, the capacitor device can be automatically located in the center of the plug-in cabinet during installation, ensuring that the capacitor device is equally spaced from the left and right sides of the plug-in cabinet, thereby ensuring the heat dissipation efficiency and operational stability of the capacitor device during operation;

[0026] By providing a positioning locking mechanism and utilizing the cooperation between the trigger assembly and the connection assembly, during the insertion and placement of the capacitor device, the cooperation between the transverse movement structure in the connection assembly and the trigger member allows the capacitor device to be inserted and placed past the electrode sheets, and the two sets of electrode sheets are simultaneously forced to move closer together until the capacitor device can no longer be pushed inward, locking the position of the electrode sheets. Subsequently, when the capacitor device is released, the trigger assembly can push the capacitor device to automatically slide outward, thereby completing the electrical connection with the electrode sheets, making the entire installation process quick and convenient.

[0027] By setting up an unlocking component, when the capacitor device is subsequently disassembled, pressing the trigger block inward can drive the two sets of electrode plates away from each other, thereby releasing the locked state of the capacitor device. At the same time, with the cooperation of the trigger component, the capacitor device can automatically slide to the outside of the cabinet, making the disassembly operation simple.

[0038] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0039] In addition, numerous specific details are provided in the following specific examples to better illustrate the present application. Those skilled in the art will appreciate that the present application can be practiced without certain specific details. In some instances, methods, means, and components well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present application.

[0040] See also Figures 1-8 In an embodiment of the present invention, a fast-assembly series capacitor energy storage device includes:

[0041] A cabinet 1, wherein a plurality of plug-in cabinets 101 are provided in the cabinet 1, wherein capacitor devices 2 are detachably installed in the plug-in cabinets 101;

[0042] Preferably, see Figure 1 Figure 2 、 Figure 3 The above-mentioned plug-in cabinets 101 are arranged in three groups at equal intervals along the longitudinal direction of the cabinet 1, and each group of plug-in cabinets 101 is separated by partitions.

[0043] Specifically, see Figure 1 、 Figure 2 、 Figure 4 The left and right side walls of the plug-in cabinet 101 are respectively fixed with guide blocks 5, and both sets of guide blocks 5 are provided with arc guide surfaces 501;

[0044] When assembling the capacitor device 2 into the plug-in cabinet 101, the arc guide surfaces 501 on the two sets of guide blocks 5 cooperate with the cabinet body of the capacitor device 2 to correct the capacitor device 2 so that the capacitor device 2 is inserted and installed in the center of the plug-in cabinet 101, so that the distance between the capacitor device 2 and the left and right sides of the plug-in cabinet 101 is equal, thereby ensuring the heat dissipation efficiency of the capacitor device 2 when working.

[0045] The plug-in cabinet 101 is provided with a positioning locking mechanism, which includes a trigger assembly and a connection assembly. The trigger assembly includes a trigger member elastically slidably arranged in the plug-in cabinet 101, and the connection assembly includes two groups of electrode sheets 4 symmetrically arranged along the length direction of the plug-in cabinet 101, and each group of electrode sheets 4 is fixedly provided with a transverse movement structure;

[0046] It should be noted that the guide block 5 is closer to the outside of the cabinet 1 than the electrode sheet 4. When the capacitor device 2 is inserted and placed, the guide block 5 will first align the capacitor device 2. After the alignment is completed, the capacitor device 2 will pass over the electrode sheet 4. Therefore, during the assembly of the capacitor device 2, the alignment process of the capacitor device 2 will not interfere with the electrode sheet 4.

[0047] During the process of inserting the capacitor device 2 into the plug-in cabinet 101, the capacitor device 2 can push the trigger member to retract into the plug-in cabinet 101. During the retraction of the trigger member, the trigger member cooperates with the transverse movement structure to drive the two groups of electrode sheets 4 to approach each other and lock the capacitor device 2.

[0048] The trigger assembly includes a slide bar 6 fixedly arranged in the plug-in cabinet 101, and two groups of slide bars 6 are symmetrically arranged along the length direction of the plug-in cabinet 101. A first spring 7 is sleeved on each of the two groups of slide bars 6. One end of the first spring 7 abuts against the cabinet 1, and the other end abuts against the push plate 3 slidably arranged on the two groups of slide bars 6;

[0049] In particular, see Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 , the first spring 7 is always in a compressed state, and the first spring 7 in the compressed state pushes the push plate 3 to move toward the outside of the cabinet 1, so that in the initial state, the push plate 3 is close to the cabinet door of the cabinet 1; at this time, under the cooperation of the trigger member and the transverse movement structure, the two groups of electrode sheets 4 are away from each other (such as Figure 2 The plug-in cabinet 101 in the middle (as shown in the state) can make way for the insertion of the capacitor device 2 so that the capacitor device 2 can be normally inserted into the plug-in cabinet 101.

[0050] For details, see Figure 1-Figure 7 The trigger member includes a fixing plate 9 fixedly arranged on the pushing plate 3, and two groups of fixing plates 9 are symmetrically arranged along the length direction of the pushing plate 3, and the two groups of fixing plates 9 are fixedly provided with a protruding column 901;

[0051] The transverse movement structure includes a transverse movement plate 8 fixedly connected to the electrode sheet 4. The transverse movement plate 8 is provided with a composite groove. The protruding column 901 is slidably arranged in the composite groove. When the pushing plate 3 slides relative to the plug-in cabinet 101, the protruding column 901 cooperates with the composite groove to drive the electrode sheet 4 to slide along the length direction of the plug-in cabinet 101.

[0052] Specifically, see Figure 7 The above-mentioned transverse plate 8 is slidably connected to the guide rod 13 fixed on the partition, and the guide rod 13 is sleeved with a second spring 14, one end of the second spring 14 abuts against the transverse plate 8, and the other end abuts against the end of the guide rod 13.

[0053] Furthermore, the second spring 14 is always in a compressed state, and can push the transverse plate 8 to move toward the middle of the plug-in cabinet 101 along the length direction of the plug-in cabinet 101 .

[0054] The composite groove includes a vertical groove 801 formed on the transverse plate 8, with an oblique groove 802 and a horizontal groove 804 connected to the end of the vertical groove 801. The horizontal groove 804 is connected to the oblique groove 802 via a reset groove 803. A first guide and a second guide are provided at the connection between the oblique groove 802, the vertical groove 801 and the reset groove 803, respectively.

[0055] Specifically, see Figure 8 The above-mentioned inclined groove 802, reset groove 803 and horizontal groove 804 are arranged into a "right triangle" structure, and the three are clearly distinguished by the separator block 19.

[0056] The first guide member includes a first deflection plate 15 rotatably mounted at the connection between the inclined slot 802 and the vertical slot 801. The first deflection plate 15 is elastically connected to the transverse plate 8 via a first elastic piece 17. Specifically, the first deflection plate 15 is rotatably mounted on the partition block 19 and elastically connected to the partition block 19 via the first elastic piece 17. In the initial state, under the cooperation of the first elastic piece 17, the first deflection plate 15 blocks the horizontal slot 804, and the first deflection plate 15 can only deflect clockwise toward the inclined slot 802 (refer to FIG. Figure 8 describe);

[0057] The second guide member includes a second deflection plate 16 rotatably mounted at the connection between the inclined groove 802 and the reset groove 803. The second deflection plate 16 is elastically connected to the transverse plate 8 via a second elastic piece 18. Specifically, the second deflection plate 16 is rotatably mounted on the partition block 19 and elastically connected to the partition block 19 via the second elastic piece 18. In the initial state, under the cooperation of the second elastic piece 18, the second deflection plate 16 blocks the inclined groove 802, and the second deflection plate 16 can only deflect clockwise toward the reset groove 803 (refer to FIG. Figure 8 describe);

[0058] In the initial state, the protruding post 901 is located at the end of the stroke of the vertical slot 801 away from the inclined slot 802. At this time, the two sets of electrode sheets 4 are away from each other. When inserting and placing the capacitor device 2, the guide block 5 will first align the capacitor device 2. After the alignment is completed, the capacitor device 2 will continue to be pushed. The capacitor device 2 will pass over the electrode sheet 4 and continue to move toward the inside of the cabinet 1 until the capacitor device 2 contacts the pushing plate 3. Then, the capacitor device 2 will continue to be pushed. At this time, the pushing plate 3 will first retract inward to squeeze the first spring 7. At the same time, the protruding post 901 slides along the vertical slot 801. When the protruding post 901 moves to the end of the stroke of the vertical slot 801 When the first deflection plate 15 engages with the inclined groove 802, the capacitor device 2 completely passes over the electrode sheet 4 and is in a state of just passing over the electrode sheet 4. When the capacitor device 2 is subsequently pushed further, the protruding post 901 will slide along the inclined groove 802 under the guidance of the first deflection plate 15. During this process, the squeezing of the inclined groove 802 by the protruding post 901 can force the two sets of transverse plates 8 to drive the two sets of electrode sheets 4 closer to each other. At the same time, the protruding post 901 can push the second deflection plate 16 to deflect toward the reset groove 803. When the protruding post 901 moves to the end of the travel of the inclined groove 802, the second deflection plate 16 returns to its initial position under the action of the second elastic piece 18.

[0059] At this time, the capacitor device 2 will be unable to push, and the electrode sheet 4 moves to the extreme position; then, the capacitor device 2 is released, and the first spring 7 will release part of the elastic potential energy, pushing the push plate 3 and the capacitor device 2 to move outward; during this process, the protrusion 901 moves along the reset groove 803 until the protrusion 901 moves to the end of the stroke of the reset groove 803, the position of the capacitor device 2 and the push plate 3 is fixed, and the terminal on the capacitor device 2 is just connected to the electrode sheet 4, thereby completing the electrical connection between the capacitor device 2 and the cabinet 1.

[0060] It should be noted that when the protrusion 901 moves to the end of the stroke of the reset groove 803, since the second spring 14 is always in a compressed state, in this state, the protrusion 901 will be stably located at the connecting inflection point of the reset groove 803 and the horizontal groove 804, thereby fixing the position of the electrode sheet 4 and facilitating the connection between the capacitor device 2 and the electrode sheet 4.

[0061] Further, see Figure 4-Figure 8 , the plug-in cabinet 101 is further provided with an unlocking component, which can drive the two groups of electrode sheets 4 away from each other;

[0062] The unlocking assembly includes a trigger block 10 slidably mounted on the cabinet 1 , and two sets of unlocking blocks 11 are symmetrically fixedly mounted on the trigger block 10. The two sets of unlocking blocks 11 cooperate with wedge blocks 12 fixedly mounted on the two sets of transverse plates 8 to drive the two sets of electrode sheets 4 away from each other.

[0063] Preferably, the unlocking block 11 and the wedge block 12 are both configured as a "right-angled trapezoidal structure", each including a guide inclined surface 1101 and an inclined surface 1201;

[0064] In the initial state, see Figure 5 The trigger block 10 is in the middle position. At this time, the two groups of electrode plates 4 are away from each other, the inclined surface 1201 of the wedge block 12 does not contact the guiding inclined surface 1101 of the unlocking block 11, and the trigger block 10 can slide freely on the partition along the depth direction of the plug-in cabinet 101.

[0065] When the capacitor device 2 is inserted into the plug-in cabinet 101, the two sets of electrode sheets 4 close to each other can drive the inclined surfaces 1201 of the two sets of wedge blocks 12 to fit with the guiding inclined surfaces 1101 of the unlocking block 11 (state as shown in FIG. Figure 5 The remaining two groups of trigger blocks 10 are shown), at this time, the two groups of wedge blocks 12 can position the trigger blocks 10 so that the positions of the trigger blocks 10 remain fixed.

[0066] When the capacitor device 2 needs to be disassembled, the trigger block 10 is pressed inward, and the guide inclined surface 1101 of the unlocking block 11 cooperates with the inclined surface 1201 of the wedge block 12, which can force the wedge block 12 to drive the two groups of electrode sheets 4 away from each other. During this process, the transverse plate 8 slides along the length direction of the plug-in cabinet 101; at the same time, the protruding post 901 slides along the horizontal groove 804 and pushes the first deflection plate 15 to deflect toward the inclined groove 802; until the protruding post 901 moves to engage with the vertical groove 801, the first deflection plate 15 returns to its original position under the action of the first elastic piece 17 Position, the electrode sheet 4 returns to its initial position, and then the compressed first spring 7 releases its elastic potential energy, pushing the push plate 3 and the capacitor device 2 to move a certain distance to the outside of the cabinet 1. At the same time, the protrusion 901 slides along the vertical slot 801 until the protrusion 901 moves to the end of the stroke of the vertical slot 801, and the push plate 3 stops moving. At this time, the capacitor device 2 moves outward for a distance but is not able to completely detach from the plug-in cabinet 101. Subsequently, the capacitor device 2 is pulled outward to achieve complete separation of the capacitor device 2 from the cabinet 1; the whole process is quick and convenient.

[0067] A method for assembling a fast-assembly series capacitor energy storage device is also proposed, comprising the following steps:

[0068] Step 1: In the initial state, the two sets of electrode sheets 4 are away from each other, and the push plate 3 is close to the door of the cabinet 1;

[0069] When assembling the capacitor device 2, insert the capacitor device 2 into the plug-in cabinet 101. When inserting, the guide block 5 aligns the capacitor device 2 so that the capacitor device 2 is located in the center of the plug-in cabinet 101.

[0070] Step 2: When the capacitor device 2 contacts the push plate 3, as the push plate 3 retracts, the protrusion 901 slides in the vertical slot 801 until the capacitor device 2 passes over the electrode sheet 4. The capacitor device 2 is then pushed further, and the protrusion 901 cooperates with the inclined slot 802 to force the two sets of electrode sheets 4 closer together. When the capacitor device 2 cannot be pushed any further, the capacitor device 2 is released, and the first spring 7 pushes the capacitor device 2 to move a certain distance.

[0071] Step 3: During this process, the protrusion 901 slides along the reset groove 803 until the protrusion 901 cannot move any further, and the capacitor device 2 is connected to the electrode sheet 4;

[0072] Step 4: When disassembling the capacitor device 2, press the trigger block 10 inward, and the unlocking block 11 cooperates with the wedge block 12 to force the two groups of electrode sheets 4 to move away from each other. At the same time, with the cooperation of the pushing plate 3, the capacitor device 2 will automatically protrude outward.

The fast-assembly series capacitor energy storage device according to claim 1, characterized in that: Guide blocks (5) are fixedly provided on the left and right side walls of the insertion cabinet (101), respectively, and arc guide surfaces (501) are provided on both sets of the guide blocks (5).

10. A method for assembling a fast-assembly type series capacitor energy storage device, using the fast-assembly type series capacitor energy storage device according to claim 1, characterized in that: The steps include: Step 1: In the initial state, the two sets of electrode sheets (4) are separated from each other, and the push plate (3) is close to the cabinet door (1); When assembling the capacitor device (2), the capacitor device (2) is inserted into the plug-in cabinet (101). When inserting, the guide block (5) aligns the capacitor device (2) so that the capacitor device (2) is located at the center of the plug-in cabinet (101); Step 2: When the capacitor device (2) contacts the push plate (3), the push plate (3) retracts and the protruding column (901) slides in the vertical groove (801) until the capacitor device (2) passes over the electrode sheet (4). The capacitor device (2) is pushed further and the protruding column (901) cooperates with the inclined groove (802) to force the two sets of electrode sheets (4) to approach each other until the capacitor device (2) can no longer be pushed. The capacitor device (2) is released and the first spring (7) pushes the capacitor device (2) to move a certain distance. Step 3: During this process, the protruding column (901) slides along the reset groove (803) until the protruding column (901) cannot move, and the capacitor device (2) is connected to the electrode sheet (4); Step 4: When disassembling the capacitor device (2), press the trigger block (10) inward, and the unlocking block (11) cooperates with the wedge block (12) to force the two sets of electrode sheets (4) to move away from each other. At the same time, with the cooperation of the push plate (3), the capacitor device (2) will automatically protrude outward.
