[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings.

[0023] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. In addition, the descriptions of "preferred", "sub-preferred", etc. in the present invention are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "preferred" or "sub-preferred" may explicitly or implicitly include at least one such feature.

[0024] like Figure 1-5 As shown, a through-core capacitor withstand voltage detection device includes a base 1, a bracket assembly 2 and two guide slides 3 arranged in the bracket assembly 2 and longitudinally arranged are provided on the top surface of the base 1, a slider 4 is sleeved on the guide slide 3, and a supporting plate 5 is provided between the top surfaces of the sliders 4 of the guide slides 3 on both sides, a longitudinally arranged electric cylinder 6 is provided on the top surface of the base 1 and the moving end is connected to the supporting plate 5 to drive the supporting plate 5 to slide along the guide slide 3, a tray positioning frame assembly 8 for positioning the through-core capacitor loading tray 7 is provided on the top surface of the supporting plate 5, a detection plate 9 is provided on the upper side of the supporting plate 5, two vertically arranged movable limit rods 10 passing through the bracket assembly 2 are provided on the top surface of the detection plate 9, a motor 11 with a downwardly arranged rotating shaft is provided on the bracket assembly 2, a driving member 12 is provided on the detection plate 9 for cooperating with the rotating shaft of the motor 11 to drive the detection plate 9 to move up and down, and a plurality of voltage detection contact groups respectively in contact with the conductive ends of the through-core capacitor are provided on the bottom surface of the detection plate 9, and the voltage detection contact group includes two voltage detection contacts 13 respectively in contact with the two conductive ends of the through-core capacitor. The outer side surface of the end of the rotating shaft of the motor 11 is provided with an external thread, and the driving member 12 is provided with a driving member threaded hole that cooperates with the rotating shaft of the motor 11.

[0025] Before the withstand voltage test, the through-hole capacitors to be tested are placed on the tray 7, as shown in the following figure: Figure 3-4As shown, three rows of through-core capacitors to be tested are provided on the tray 7 in this case; during the test, the tray 7 together with the through-core capacitors to be tested are positioned and placed on the tray positioning frame assembly 8. After the test is started, the moving end of the electric cylinder 6 drives the supporting plate 5 to move, thereby driving the tray positioning frame assembly 8, the tray 7 and the through-core capacitors to be tested to move into the bracket assembly 2 together. When the first row of through-core capacitors moves to the test position, the electric cylinder 6 stops working, and then controls the motor 11 to rotate. Under the action of the screw rotation of the driving member 12, the detection plate 9 moves downward, so that the voltage detection contacts 13 of each voltage detection contact group on the detection plate 9 are respectively in contact with the two conductive ends of the corresponding through-core capacitors, and then the control host provided on the machine base 1 controls each voltage detection contact group to contact each The through-core capacitors are subjected to a withstand voltage test, and the test results are displayed on the display on the machine base 1; when the test of the first row of through-core capacitors is completed, the motor 11 rotates in the opposite direction to move the detection plate 9 upward, so that each voltage detection contact group is separated from the through-core capacitors, and then the tray positioning frame assembly 8, the tray 7 and the through-core capacitors to be tested are driven to continue to move by the electric cylinder 6. When the second row of through-core capacitors moves to the test position, the electric cylinder 6 stops working, and then the motor 11 rotates to drive the detection plate 9 to move downward so that each voltage detection contact group is in contact with each through-core capacitor and a withstand voltage test is performed, until the three rows of through-core capacitors have completed the withstand voltage test respectively, the electric cylinder 6 works to drive the tray 7 to move and send it out of the bracket assembly 2, realizing the function of quickly and accurately performing withstand voltage tests on multiple through-core capacitors.

[0026] like Figure 3-4 As shown, the tray positioning frame assembly 8 includes two supporting blocks 81 arranged horizontally on the top surface of the supporting plate 5, and the tops of the supporting blocks 81 are located on the opposite sides of the two supporting blocks 81 and are respectively provided with positioning grooves 811 for the through-core capacitor loading tray 7 to be installed; positioning bosses 83 are respectively provided on both sides of the top surface of the supporting plate 5 between the two supporting blocks 81, and tray positioning holes 71 are respectively provided on both sides of the through-core capacitor loading tray 7 to cooperate with the positioning bosses 83, so that the tray 7 is positioned and installed on the supporting plate 5; a buffer part 82 is provided in the positioning groove 811, which plays a buffering role when the tray 7 is placed.

[0027] like Figure 4 As shown, a plurality of rows of through-core capacitors are provided on the through-core capacitor loading tray 7, and the bottom of the through-core capacitor extends through the through-core capacitor loading tray 7. A plurality of transverse partitions 84 are provided on the top surface of the supporting plate 5 and located between the two supporting blocks 81 for transversely separating the through-core capacitors. A plurality of longitudinal partitions 85 are provided between the two transverse partitions 84 for longitudinally separating the through-core capacitors, which independently separate the lower parts of the through-core capacitors to avoid mutual influence during testing.

[0028] like Figure 4-5As shown, the voltage detection contact group is arranged horizontally on the bottom surface of the detection board 9, and a detection contact separation plate 91 is provided between adjacent voltage detection contact groups to separate the upper parts of the same through-core capacitors during the withstand voltage test to avoid mutual influence.

[0029] like Figure 4 As shown, the length of the detection contact separation plate 91 is less than the sum of the lengths of the voltage detection contact 13 and the upper portion of the through-core capacitor, ensuring that the voltage detection contact 13 is in contact with the conductive end of the through-core capacitor.

[0030] like Figure 1-3 As shown, the bracket assembly 2 includes a frame 21 disposed on the outside of the support plate 5. A motor mounting plate 22 is provided on the top surface of the frame 21. The motor 11 is mounted on the motor mounting plate 22, and the motor 11 shaft passes through the motor mounting plate 22. The motor mounting plate 22 is provided with a mounting plate limiting hole 221 for the movable limiting rod 10 to pass through. When the motor 11 rotates, the movable limiting rod 10 cooperates with the mounting plate limiting hole 221 to limit the upward and downward movement of the detection plate 9, ensuring that the voltage detection contact group on the detection plate 9 contacts the conductive ends of the lower through-core capacitors.

[0031] like Figure 1-2 As shown, protective baffles 23 are respectively provided on the front side, left side, right side and upper side of the rear side of the frame 21 to play a protective role and improve the safety of the pressure test.

[0032] The above are only preferred embodiments of the present invention and do not limit the patent scope of the present invention.
