However, for high-voltage distribution boxes of different depths, the interface on the distribution box and the detection terminals on the bench cannot be located at the same height, the bending degree of the connection between the detection terminals and the cable and the connection between the interface and the cable is too large, the cable is prone to breakage, and the connection end is prone to poor contact, which is not conducive to the learning, understanding and maintenance test task of the high-voltage distribution box.

[0037] It is found through research that, as shown in Figures 1-3 by arranging the adjusting structure, the interface on the distribution box and the detection terminals on the bench body are located at the same height, the problem that the interface on the distribution box and the detection terminals on the bench in the prior art cannot be located at the same height, the bending degree of the connection between the detection terminals and the cable and the connection between the interface and the cable is too large, the cable is prone to breakage, and the connection end is prone to poor contact are solved, the test effect of the bench on the high-voltage distribution box is improved, and the stability of the connection of the detection terminals of the high-voltage distribution box performance test bench in the teaching process is improved, which facilitates the use in the teaching process.

[0038] In order to better understand the above technical solution, the above technical solution will be described in detail in combination with the drawings of the specification and specific embodiments.

[0039] As shown in Figures 1-3 a high-voltage distribution box performance test bench, comprising a bench body 1 and a distribution box 2 placed on the bench body 1;

[0040] A panel 10 and an adjusting structure are arranged on the bench body 1, a test back plate and a plurality of detection terminals 12 are installed on the panel 10, and the plurality of detection terminals 12 are electrically connected with the test back plate;

[0041] A plurality of interfaces 20 are arranged on the distribution box 2, and each interface 20 is connected with a corresponding detection terminal 12 through a cable 121;

[0042] The placing surface of the frame body 1 is provided with a through groove;

[0043] The adjusting structure comprises a fixing block 13 and a supporting block 14, the fixing block 13 is located below the supporting block 14 and is fixedly connected with the frame body 1, a threaded rod 3 is installed on the fixing block 13, the threaded rod 3 is threadedly connected with the fixing block 13, and one side of the threaded rod 3 close to the supporting block 14 is rotationally connected with the supporting block 14 through a rotating disc 30;

[0044] The supporting block 14 is located below the through groove and slides along the vertical direction of the frame body 1 under the driving of the threaded rod 3.

[0045] During testing, the distribution box 2 is located on the supporting block 14 through the through groove, and the supporting block 14 is used to control the multiple interfaces 20 on the distribution box 2 to be in the same height as the multiple detection terminals 12 on the test backboard.

[0046] By setting the adjusting structure in the form of the fixing block 13 and the supporting block 14 and adjusting the height of the supporting block 14 in the vertical direction of the frame body 1 by using the threaded rod 3 arranged on the fixing block 13, the height of the interface 20 on the distribution box 2 is adjusted to be in the same height as the detection terminal 12 on the frame body 1, thereby solving the problem in the prior art that the height difference between the placing surface of the rack and the detection terminal 12 arranged on the rack is always consistent, the interface 20 on the distribution box 2 cannot be in the same height as the detection terminal 12 on the rack for high-voltage distribution boxes of different depths, the bending degree of the connection between the detection terminal 12 and the cable 121 and the connection between the interface 20 and the cable 121 is too large, the cable 121 is easily broken, and the connection between the detection terminal 12 and the cable 121 is unstable during the teaching process, thereby improving the testing effect of the rack on the high-voltage distribution box and the stability of the detection terminal 12 connected to the high-voltage distribution box performance testing rack during the teaching process, and facilitating the use during the teaching process.

[0047] Specifically, in the prior art, the high-voltage distribution box performance testing rack displays the detailed structure inside the high-voltage distribution box through the test backboard on the equipment teaching panel 10, which facilitates students to understand and effectively master knowledge, and corresponding components and indicator lights are fixed on the test backboard, so that the performance of the internal elements of the high-voltage distribution box can be intuitively judged when the internal elements of the high-voltage distribution box work.

[0048] As shown in Figure 3 One end of the fixing block 13 away from the supporting block 14 is provided with an internal thread sleeve 131, the threaded rod 3 passes through the internal thread sleeve 131 and is threadedly connected with the internal thread sleeve 131.

[0049] The internal thread sleeve 131 is integrally formed with the fixing block 13.

[0050] By setting the internal thread sleeve 131 below the fixed block 13, without increasing the thickness of the fixed block 13, the stability of the threaded rod 3 and the fixed block 13 during rotation is enhanced by the internal thread sleeve 131.

[0051] As shown in Figure 3 The side of the supporting block 14 away from the fixed block 13 is provided with at least one limiting block 141, and the low end of the distribution box 2 is provided with a groove 21 matched with the limiting block 141.

[0052] The distribution box 2 is fixed with the supporting block 14 through the limiting block 141 and the groove 21.

[0053] By setting the limiting block 141 and the groove 21, the stability of the distribution box 2 placed on the supporting block 14 is improved, which is convenient for teaching work of the rack.

[0054] As shown in Figure 1 A plurality of limiting rings 11 are arranged on the test backboard, and each limiting ring 11 is provided with an indicator lamp inside, and the plurality of indicator lamps are electrically connected with the test backboard.

[0055] The limiting ring 11 is arranged on the test backboard, and the limiting ring 11 is arranged on the outer surface of the corresponding indicator lamp.

[0056] The limiting ring 11 is detachably connected with the test backboard.

[0057] By setting a plurality of limiting rings 11, the corresponding indicator lamp is covered by the limiting ring 11, and the limiting ring 11 is arranged in a detachable manner with the test backboard. When the rack is used in a place with strong light, the limiting ring 11 is covered on the corresponding indicator lamp, and the covering of the limiting ring 11 can facilitate the observation of whether the indicator lamp is on in a place with strong light. When the rack is used in a laboratory with weak indoor light, the plurality of limiting rings 11 are detached from the test backboard, which can facilitate the observation of whether the plurality of indicator lamps are on. The problem that the existing rack indicator lamp cannot clearly indicate whether the indicator lamp is on in a place with strong light is solved, and the rack is convenient for teaching test in a place with high light intensity.

[0058] As shown in Figure 3 The end of the threaded rod 3 away from the rotating disc 30 is provided with a handle 31, and the handle 31 is L-shaped, which is convenient for rotation of the threaded rod 3.

[0059] During work, the corresponding interface 20 and detection terminal 12 are connected by the cable 121 to complete the electrical connection between the distribution box 2 and the test backboard of the rack.

[0060] After the connection is completed, the groove 21 on the distribution box 2 is sleeved on the corresponding limiting block 141 to complete the fixation between the distribution box 2 and the supporting block 14.

[0061] Then, according to the position of the interface 20 on the distribution box 2, the threaded rod 3 is rotated, since the threaded rod 3 is threadedly connected with the fixed block 13, when the threaded rod 3 is rotated, the threaded rod 3 moves along the vertical direction of the frame body 1, since the threaded rod 3 is rotationally connected with the supporting block 14 through the rotating disc 30, the supporting block 14 moves along the vertical direction of the frame body 1 with the movement of the threaded rod 3, and then the distribution box 2 is lifted to different heights;

[0062] According to the position of the interface 20 on the distribution box 2, the height of the distribution box 2 is adjusted, so that the interface 20 on the distribution box 2 is level with the detection terminal 12 on the frame body 1, and the protection of the cable 121 between the interface 20 and the detection terminal 12 is reduced.

[0063] Specifically, the length of the cable 121 used near the test backboard side of the distribution box 2 is equal to or slightly greater than the distance between the distribution box 2 and the test backboard, which can further protect the cable 121 and reduce the use of cable 121 material.

[0064] It should be noted that the distribution box 2 refers to a high-voltage distribution box, and the test backboard is a test system integrated with high-voltage distribution box performance, and the cable 121 is used to connect the high-voltage distribution box and the high-voltage distribution box performance test system to complete the performance test of the high-voltage distribution box.

[0065] In summary, compared with the prior art, the following beneficial effects are achieved:

[0066] 1. By setting the adjusting structure, the height of the rack placement surface is constant, and the height difference between the rack placement surface and the detection terminal 12 provided on the rack is always consistent. For high-voltage distribution boxes of different depths, the interface 20 on the distribution box 2 and the detection terminal 12 on the rack cannot be at the same height, the connection between the detection terminal 12 and the cable 121, and the connection between the interface 20 and the cable 121 are bent too much, which causes the cable 121 to be easily broken and the connection end to be poorly contacted.

[0067] 2. By setting multiple limiting rings 11, the corresponding indicator lights are covered by the limiting rings 11, and the limiting rings 11 are installed in a detachable manner with the test backboard. When the rack is used in a place with strong light, the limiting rings 11 are covered on the corresponding indicator lights, and the covering of the limiting rings 11 can facilitate the observation of whether the indicator lights are on in a place with strong light. When the rack is used in a laboratory with weak indoor light, the multiple limiting rings 11 are all detached from the test backboard, which can facilitate the observation of whether the multiple indicator lights are on, and solves the problem that the indicator lights of the existing rack cannot clearly indicate whether the indicator lights are on in a place with strong light, and facilitates the teaching test of the rack in a place with high light intensity.
