Description

Technical Field

[0001] This utility model relates to the field of debugging device technology, and in particular to a tuned series resonance test device. Background Technology

[0002] The series resonant test device is used in power systems to conduct withstand voltage tests on high-voltage power equipment and cables. It mainly consists of a variable frequency power supply platform, an excitation transformer, reactors, a voltage divider, and compensation capacitors, forming a series resonant circuit. When the input power frequency equals the resonant frequency of the resonant circuit, the series resonant circuit will form a high impedance, thus maximizing the test current. The reactors are primarily used to adjust the operating voltage; this function is achieved by stacking reactors during the series resonant test. The reactors require a base for installation during the series resonant test setup.

[0003] In order to improve the support stability of the reactor, most reactor bases / frames are often equipped with multiple protruding support rods to increase the support area. However, this structure is inconvenient to carry and difficult to assemble in actual use, thus reducing the installation efficiency of the reactor in series resonant tests.

[0004] Therefore, it is necessary to provide a new tuned series resonant test device to solve the above-mentioned technical problems. Utility Model Content

[0007] The support assembly includes a support plate, one end of which is provided with symmetrically distributed support blocks. A rotating rod is inserted and fixedly connected between two of the support blocks, and the end of the rotating rod is rotatably connected to the side wall of the mounting groove.

[0008] Preferably, the outer wall of the support block is provided with two vertically distributed docking blocks, and the outer wall of the docking block near the support plate is provided with a fixedly connected adapter rod a, and the outer wall of the support plate away from the support block is provided with a fixedly connected adapter rod b, and the adapter rod a and the adapter rod b are provided with the same fixedly connected protective arc plate.

[0009] Preferably, the mounting groove is provided with a limiting component for fixing the support plate. The limiting component includes a support frame, and a rotating cylinder is rotatably connected inside the support frame. Threaded screws are inserted into both sides of the rotating cylinder, and the thread directions of the outer walls of the screws on both sides are opposite.

[0010] Preferably, guide rods are fixedly connected to both sides of the support frame, and a slidingly connected linkage plate is sleeved on the outside of the guide rod, and the outer wall of the linkage plate is connected to the end of the screw.

[0011] Preferably, the outer wall of the linkage plate is provided with a fixedly connected plug on the side away from the screw, the docking block has a docking hole inside, and the outer wall of the plug abuts against the inner wall of the docking hole.

[0012] Preferably, the support plate has a threaded adjusting rod inserted inside, the end of the adjusting rod has a rotatably connected adjusting plate, and the adjusting plate has sliding rods on both sides of the outer wall of the adjusting rod, and the outer wall of the sliding rod abuts against and slides in connection with the inside of the support plate.

[0013] Compared with related technologies, the tuned series resonant test device provided by this utility model has the following advantages:

[0014] 1. By folding the support components, this utility model forms an integrated structure with the base plate and reactor, making it more flexible and convenient for workers to carry the entire device during later use.

[0015] 2. After the experimental test is completed, the support plate in the support assembly is folded.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0025] Please see Figures 1 to 5 The present invention provides a tuned series resonance test device, which includes a base plate 1.

[0026] In the embodiments of this utility model, please refer to Figures 1 to 5 A reactor 2 is provided on the base plate 1. Several annularly distributed mounting grooves 11 are opened inside the base plate 1, and a support assembly 3 is provided inside the mounting groove 11 to support the base plate 1. The support assembly 3 includes a support plate 31. One end of the support plate 31 is provided with symmetrically distributed support blocks 32. A rotating rod 33 is inserted and fixedly connected between two support blocks 32, and the end of the rotating rod 33 is rotatably connected to the side wall of the mounting groove 11. Two vertically distributed docking blocks 321 are provided on the outer wall of the support block 321. A fixedly connected adapter rod a34 is provided on the outer wall of the docking block 321 near the support plate 31. A fixedly connected adapter rod b35 is provided on the outer wall of the support plate 31 away from the support block 32. A protective arc plate 4 is provided on the adapter rod a34 and the adapter rod b35.

[0027] It should be noted that by rotating the support plate 31 to the base plate 1, the support plate 31 and the base plate 1 can form an integral structure. In use, the support plate 31 can be unfolded outward to expand the support area of ​​the base plate 1, thereby making the support of the base plate 1 for the reactor 2 more stable. After the device is used, the unfolded support plate 31 is folded and fixed. The protective arc plate 4 on the outer wall of the support plate 31 will abut against the outer wall of the reactor 2. At this time, the support plate 31 and the protective arc plate 4 can achieve double protection for the outer wall of the reactor 2, thereby reducing the probability of the reactor 2 being damaged by bumps during transportation.

[0028] In the embodiments of this utility model, please refer to Figures 1 to 5 The mounting groove 11 is provided with a limiting component 5 for fixing the support plate 31. The limiting component 5 includes a support frame 51. A rotating cylinder 52 is rotatably connected inside the support frame 51. Threaded screws 521 are inserted into both sides of the rotating cylinder 52. The threads on the outer walls of the two screws 521 are opposite in direction. Guide rods 53 are fixedly connected on both sides of the support frame 51. A sliding linkage plate 54 is sleeved on the outside of the guide rods 53. The outer wall of the linkage plate 54 is connected to the end of the screw 521. A fixedly connected insertion rod 541 is provided on the side of the outer wall of the linkage plate 54 away from the screw 521. A docking hole 322 is opened inside the docking block 321. The outer wall of the insertion rod 541 abuts against the inner wall of the docking hole 322.

[0029] It should be noted that since the threads on the two screws 521 are in opposite directions, during use, when the operator controls the rotating cylinder 52 to rotate, the two screws 521 can move relative to each other or in opposite directions, thereby driving the external insertion rod 541 to move synchronously relative to each other or in opposite directions. Therefore, in actual use, the state between the insertion rod 541 and the docking hole 322 can be flexibly controlled. When the insertion rod 541 is inserted into the docking hole 322, the external support plate 31 can be fixed. When the insertion rod 541 is removed from the docking hole 322, the fixing limit on the external support plate 31 can be released, and the operator can flexibly control the rotation of the support plate 31.

[0030] In the embodiments of this utility model, please refer to Figures 1 to 5 The support plate 31 is fitted with a threaded adjusting rod 62. The end of the adjusting rod 62 is fitted with an adjusting plate 6 that is rotatably connected. The adjusting plate 6 has sliding rods 61 on both sides of the outer wall of the adjusting rod 62. The outer wall of the sliding rod 61 abuts against and slides with the inside of the support plate 31.

[0031] It should be noted that by using the adjusting rod 62 to be installed movably, when the ground becomes uneven during use, the adjusting rod 62 can be controlled to move the adjusting plate 6 to adjust the distance between the bottom of the corresponding support plate 31 and the ground, so that each support plate 31 can smoothly abut against the ground, thus enabling the base plate 1 located between the support plates 31 to provide stable support for the reactor 2.

[0032] The working principle of the tuned series resonant test device provided by this utility model is as follows:

[0033] When using this device, the operator can first move the device to the required position, and then control the rotating cylinder 52 to rotate. The rotating cylinder 52 will drive the screws 521 on both sides inside to move relative to each other. The relatively moving screws 521 will drive the insertion rod 541 to slide out from the inside of the docking hole 322 through the linkage plate 54, thereby releasing the limitation on the support plate 31.

[0034] At this point, the staff can hold and move the support plate 31, causing it to rotate inside the mounting groove 11 via the rotating rod 33. When the support plate 31 is unfolded and in a horizontal state, the docking block 321 on the other side of the outer wall of the support block 32 will move to the position opposite to the insertion rod 541. Then, the rotating cylinder 52 can be controlled to rotate in the opposite direction, causing the screws 521 on both sides to drive the external insertion rod 541 to move in opposite directions until the insertion rod 541 is inserted into the docking hole 322 in the docking block 321, thereby fixing the unfolded support plate 31.

[0035] After the multiple support plates 31 are unfolded, when the ground becomes uneven, the staff can control the adjustment rod 62 to rotate as needed. The rotating adjustment rod 62 will cause the adjustment plate 6 to slide outside the support plate 31, thereby supporting the support plate 31 on the lower side of the ground. Therefore, the multiple support plates 31 can be stably pressed against the ground. At this time, by unfolding the multiple support plates 31, the support area of ​​the base plate 1 can be increased, which can make the base plate 1 more stably support the reactor 2, so that the reactor 2 can stably carry out the series resonance experiment.

[0036] After using the device, the above operation can be repeated to control the rotating cylinder 52 to rotate, so that the insertion rod 541 first releases the limit on the support plate 31, folds the unfolded support plate 31, and fixes the folded support plate 31. Then the protective arc plate 4 on the outer wall of the support plate 31 will abut against the outer wall of the reactor 2. At this time, the support plate 31 and the protective arc plate 4 can achieve double protection for the outer wall of the reactor 2, thereby reducing the probability of damage to the reactor 2 during transportation.

[0037] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0038] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
