Description

Technical Field

[0001] The present application relates to the technical field of DC bias suppression equipment, and in particular to an integrated cabinet for DC bias suppression equipment. Background Art

[0002] DC bias refers to an abnormal working state of the transformer, mainly referring to the uneven distribution of magnetic flux in the transformer core due to the DC current flowing through the transformer winding. This phenomenon will cause the transformer core to be oversaturated, causing the excitation current waveform to be distorted, increasing the power consumption of the transformer, and also causing the temperature of the transformer to rise, seriously affecting the service life and safe operation of the transformer.

[0003] Connecting a capacitor-type DC isolation device to the transformer is one of the common means of controlling DC bias. It refers to using the characteristics of capacitors to pass AC and isolate DC to isolate the impact of DC on the transformer, thereby reducing the impact of DC on the transformer.

[0004] Capacitor-type DC isolation devices usually require an integrated cabinet to integrate various electrical equipment (including monitoring controllers, communication terminals, capacitor banks, circuit breakers, zinc oxide components, etc.) of various capacitor-type DC isolation devices. Among them, the capacitor bank includes multiple capacitors, and a separate storage compartment is usually set in the integrated cabinet to accommodate the capacitors, and multiple capacitors are layered in the storage compartment.

[0005] Since the size and layout of the integrated cabinet have been finalized when it leaves the factory, when a large number of capacitors need to be installed in the integrated cabinet, it is inconvenient for operators to install more capacitors in the integrated cabinet due to the limitations of the space inside the integrated cabinet and other components. Utility Model Content

[0006] In order to facilitate installation of a greater number of capacitors in an integrated cabinet, the present application provides an integrated cabinet for a DC bias suppression device.

[0007] The present application provides an integrated cabinet for DC bias suppression equipment, which adopts the following technical solution:

[0008] An integrated cabinet for DC bias suppression equipment comprises a cabinet body and an adjustment plate arranged in the cabinet body, wherein the adjustment plate is used to carry a capacitor, a fixing device is arranged in the cabinet body, and the fixing device is used to limit the height of the adjustment plate. The fixing device is provided in a plurality of groups, and the plurality of groups of the fixing devices are distributed in sequence along the height direction of the cabinet body.

[0009] Through the above technical solution, when a large number of capacitors need to be installed in the integrated cabinet, the operator adjusts the height of the adjustment plate, that is, fixes the adjustment plate at different heights with the help of fixing devices at different heights, thereby reducing the vertical distance between two adjacent adjustment plates. At this time, the operator can install more adjustment plates in the integrated cabinet, and then install more capacitors on the newly added adjustment plates.

[0010] In a preferred example, the utility model can be further configured as follows: the fixing device includes a plurality of support blocks and a plurality of limit rods, the plurality of limit rods and the plurality of support blocks are arranged in a one-to-one correspondence, the limit rods are arranged on the corresponding support blocks, the support blocks are all installed on the inner wall of the cabinet, the support blocks and the adjustment plate are abutted and matched, and the adjustment plate is provided with a through hole for the limit rod to pass through.

[0011] Through the above technical solution, when the operator needs to adjust the height of the adjustment plate, the adjustment plate is first placed on the support block so that the limit rod passes through the through hole on the adjustment plate. Under the support of the support block, the possibility of the adjustment plate moving downward in the vertical direction is reduced. Under the blocking effect of the limit rod on the adjustment plate, the possibility of the adjustment plate moving in the horizontal direction is reduced. Therefore, under the joint action of the support block and the limit rod, the adjustment plate is fixed.

[0012] On the contrary, when the operator needs to adjust the height of the adjustment plate, he first lifts the adjustment plate upwards so that the adjustment plate and the support block are separated from each other, and at the same time, the limit rod is disengaged from the through hole to remove the obstruction of the limit rod and the support block to the adjustment plate, so that the operator can use other fixing devices to limit the height of the adjustment plate.

[0013] In a preferred example, the utility model can be further configured as follows: a nut for pressing the adjustment plate is provided on the limiting rod, and the nut and the limiting rod are threadedly matched.

[0014] With the above technical solution, after the limit rod passes through the through hole of the adjustment plate, the operator rotates the nut so that the nut presses the adjustment plate. Due to the obstruction of the nut on the adjustment plate, the possibility of the adjustment plate moving upward in the vertical direction is reduced.

[0015] In a preferred example, the utility model can be further configured as follows: a protective washer is sleeved on the limiting rod, and the protective washer is arranged between the nut and the adjusting plate.

[0016] Through the above technical solution, the protective gasket can be made of rubber material. Under the protective effect of the protective gasket on the adjusting plate and the nut, the possibility of the adjusting plate and the nut being pressed against each other and causing damage to both is reduced.

[0017] In a preferred example, the utility model can be further configured as follows: a connecting rod is provided on the support block, a connecting hole for the connecting rod to be inserted is opened in the cabinet, and the connecting rod and the inner wall of the connecting hole are interference fit.

[0018] Through the above technical solution, before the operator installs the adjustment plate, the connecting rod on the support block is inserted into the connecting hole in advance to complete the installation of the support block, so that the adjustment plate can be supported by the support block.

[0019] After the operator completes the installation and height adjustment of the adjustment plate, the operator pulls out the connecting rod to release the supporting effect of the connecting rod on the support block, and then the support block can be removed from the integrated cabinet. This not only reduces the impact of the support block on the capacitor installation, but also reduces the impact of the subsequent support block on the vertical displacement of the adjustment plate.

[0020] In a preferred example, the utility model can be further configured as follows: a plurality of connecting rods are provided on a single support block, a connecting block is provided inside the support block, a plurality of connecting rods corresponding to the support block are installed on the connecting block, a connecting groove for the connecting block to be embedded is provided inside the support block, a sliding hole for the connecting rod to pass through is provided inside the support block, and the sliding hole and the connecting groove are connected to each other.

[0021] Through the above technical solution, the arrangement of multiple connecting rods can improve the stability of the support block installation. In addition, the connecting rods are arranged on the connecting blocks, and the connecting blocks with the connecting rods and the support blocks are arranged in a split type, thus facilitating the assembly and rapid processing of parts.

[0022] In a preferred example, the utility model can be further configured as follows: a mounting hole is provided on the top surface of the connecting block, and the limiting rod is threadedly connected to the inner wall of the mounting hole.

[0023] Through the above technical solution, after the connecting block is inserted into the supporting block and before being installed in the cabinet, the limiting rod is inserted into the mounting hole through the supporting block, so that the limiting rod is threadedly connected to the inner wall of the mounting hole. At this time, under the obstruction of the supporting block, the possibility of the connecting rod and the connecting block detaching from the supporting block is reduced, thereby improving the integrity of the limiting rod, the supporting block and the connecting block.

[0024] In a preferred example, the present invention can be further configured as follows: a handle is installed on a side wall of one end of the connecting block away from the connecting rod.

[0025] According to the technical solution, after the operator removes the adjustment plate from the support block, he or she can hold the handle and use appropriate force to pull out the connecting rod to release the connection between the support block and the cabinet.

[0026] In summary, the utility model includes the following beneficial technical effects:

[0027] 1. The operator adjusts the height of the adjustment board in the integrated cabinet to reduce the vertical distance between two adjacent adjustment boards, so that the operator can install more adjustment boards in the integrated cabinet, and then install more capacitors on the newly added adjustment boards;

[0028] 2. The support block is installed in a detachable manner in the integrated cabinet. On the one hand, it reduces the impact of the support block on the installation of the capacitor, and on the other hand, it reduces the impact of the subsequent support block on the vertical displacement of the adjustment plate.

[0036] The following is combined with Figure 1 -Attached Figure 5 This application is described in further detail.

[0037] An embodiment of the present application discloses an integrated cabinet for DC bias suppression equipment.

[0038] Refer to the attached Figure 1As shown, an integrated cabinet of a DC bias magnetic suppression device includes a cabinet body 1, and the cabinet body 1 is made of metal material.

[0039] Refer to the attached Figure 1 As shown, the cabinet top 13 is arranged in a slope shape to reduce the water flow accumulated on the cabinet body 1. The bottom, back and both sides of the cabinet body 1 are all closed (except for the necessary threading holes). Several compartments are provided inside the cabinet body 1 for installing monitoring controllers, communication terminals, capacitor banks, circuit breakers and zinc oxide components, etc. (the relevant specific component structures are not shown in the attached drawings). The front of the cabinet body 1 is open, and several cabinet doors 12 are hinged on the front of the cabinet body 1 to close the cabinet body 1 to prevent rainwater and debris from entering the cabinet body 1 and interfering with the components inside the integrated cabinet.

[0040] Refer to the attached Figure 1 and attached Figure 2 As shown, an adjustment plate 2 is arranged in the cabinet 1, and the capacitor is installed on the top surface of the adjustment plate 2. The adjustment plate 2 has a rectangular cross section, and the adjustment plate 2 is arranged horizontally in the cabinet 1.

[0041] Refer to the attached Figure 2 and attached Figure 3 As shown, a plurality of groups of fixing devices 3 are arranged in the cabinet 1 , and the fixing devices 3 are used to limit the height of the adjustment plate 2 . The plurality of groups of fixing devices 3 are evenly distributed along the height direction of the cabinet 1 .

[0042] One adjusting plate 2 corresponds to one fixing device 3 . Since the structures of each group of fixing devices 3 are basically the same, only one group of fixing devices 3 will be described in detail below.

[0043] Refer to the attached Figure 1 , Attachment Figure 2 And attached Figure 3 As shown, each set of fixing devices 3 includes four support blocks 31 and four limit rods 32 . The four support blocks 31 and the four limit rods 32 are arranged in one-to-one correspondence, and the four support blocks 31 correspond to the four corners of the same adjustment plate 2 .

[0044] Refer to the attached Figure 1 , Attachment Figure 2 And attached Figure 3 As shown, the limiting rod 32 is vertically arranged, and the limiting rod 32 is installed on the corresponding support block 31, and the support block 31 is detachably installed on the inner wall of the cabinet 1, and the top surface of the support block 31 and the bottom surface of the adjustment plate 2 are abutted and matched, and the adjustment plate 2 is provided with a through hole 21 for the limiting rod 32 to pass through. A nut 321 is installed on each limiting rod 32, and the nut 321 is used to press the top surface of the adjustment plate 2, and the nut 321 is threadedly connected to the limiting rod 32, that is, the adjustment plate 2 is arranged between the support block 31 and the nut 321.

[0045] The operator places the adjustment plate 2 on the support block 31 so as to provide installation support for the capacitor through the adjustment plate 2. Under the blocking effect of the limit rod 32 and the nut 321 on the adjustment plate 2, and under the supporting effect of the support block 31 on the adjustment plate 2, the possibility of displacement of the adjustment plate 2 is reduced, thereby improving the stability of the capacitor installation.

[0046] When the operator needs to install a large number of capacitors in the integrated cabinet, he first unscrews the nut 321, takes out the adjustment plate 2, moves the adjustment plate 2 upward or downward, and supports the adjustment plate 2 through the support blocks 31 of other groups to reduce the distance between two adjacent adjustment plates 2, so that more adjustment plates 2 can be installed in the integrated cabinet, and more capacitors can be installed in the cabinet body 1.

[0047] Refer to the attached Figure 2 and attached Figure 3 As shown, a protective washer 322 is sleeved on the limiting rod 32 . The protective washer 322 is located between the nut 321 and the adjusting plate 2 . The protective washer 322 is made of rubber material, which is beneficial to strengthen the protection of the adjusting plate 2 .

[0048] Refer to the attached Figure 2 , Attachment Figure 4 And attached Figure 5 As shown, a connecting groove 311 is provided in the support block 31, and a connecting block 5 is embedded in the connecting groove 311. The connecting block 5 is square in shape, and the connecting block 5 can slide into the connecting groove 311 and can slide out of the connecting groove 311. Two sliding holes 312 are provided in the support block 31, and the sliding holes 312 and the connecting groove 311 are interconnected. A connecting rod 4 is slidably provided in each sliding hole 312 along the horizontal direction, and the length of the connecting rod 4 is greater than the length of the sliding hole 312. Both connecting rods 4 are fixedly connected to the connecting block 5. A connecting hole 11 for plugging in the connecting rod 4 is provided in the cabinet 1, and the connecting rod 4 and the inner wall of the connecting hole 11 are interference fit. A handle 51 is fixedly connected to the connecting block 5 to facilitate the operator to pull out the connecting rod 4 and the connecting block 5. The handle 51 and the connecting rod 4 are respectively located on both sides of the connecting block 5.

[0049] Before the operator installs the adjustment plate 2, the connecting block 5 with the connecting rod 4 is inserted into the connecting groove 311 of the support block 31, so that the connecting rod 4 extends out of the support block 31, and then the connecting rod 4 is inserted into the connecting hole 11 of the cabinet 1 to complete the installation of the support block 31, so as to facilitate the installation of the adjustment plate 2 on the support block 31.

[0050] The operator pulls the handle 51 to separate the redundant support block 31 and the connecting rod 4 from the cabinet 1 , which not only reduces the impact of the support block 31 on the capacitor installation, but also reduces the impact of the subsequent support block 31 on the vertical displacement of the adjustment plate 2 .

[0051] The top surface of the connecting block 5 is provided with a mounting hole 313, and the limiting rod 32 can pass through the support block 31 and be threadedly connected to the inner wall of the mounting hole 313. After the connecting block 5 is inserted into the support block 31 and before being installed in the cabinet 1, the limiting rod 32 passes through the support and is threadedly connected to the inner wall of the mounting hole 313. Under the obstruction of the support block 31, the possibility of the connecting rod 4 and the connecting block 5 being separated from the support block 31 is reduced, thereby improving the integrity of the limiting rod 32, the support block 31 and the connecting block 5.

[0052] The implementation principle of this embodiment is: the operator adjusts the height of the adjustment plate 2 in the integrated cabinet to reduce the vertical distance between two adjacent adjustment plates 2, so that the operator can install more adjustment plates 2 in the integrated cabinet, and then install more capacitors on the newly added adjustment plates 2 to meet the energy supply requirements of the DC bias suppression equipment.

[0053] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application in sequence. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
