Under the action of a certain applied electric field strength, processes such as conduction, polarization, loss, and breakdown will also occur. Therefore, in order to detect the insulation performance, it is necessary to conduct experimental tests on them.

[0004] In the prior art, the workpiece is energized by two electrodes contacting the workpiece. However, the positions of the electrodes are fixed, which puts requirements on the size of the workpiece, and the size of the workpiece that can be detected is relatively single. At the same time, the clamping effect of the electrodes at fixed positions on the workpiece is not ideal, which will affect the conductive effect of the motor on the workpiece.

[0005] Therefore, we propose an insulation material test device. Content of the Utility Model

[0017] Beneficial effects

[0018] The present invention provides a test device for insulating materials, having the following beneficial effects:

[0019] 1. For this test device for insulating materials, by arranging a detection table, connecting the motor to a power source, the motor drives the lead screw to rotate. The lead screw moves two sliding blocks closer to each other. Then the two push plates move closer to each other and the electrodes clamp the workpiece. The electrodes can keep in close contact with the workpiece, thus ensuring the conductive effect, increasing the adaptation range for the length of the workpiece, reducing the probability that the insufficient contact between the workpiece and the electrodes affects conductivity, and improving the detection accuracy.

[0020] 2.

[0027] An insulation material testing device, as Figure 1 and Figure 2 shown, includes:

[0028] A protective cover 10 and a bottom plate 11, the bottom plate 11 is fixedly connected to the protective cover 10 and together form a sealed box structure;

[0029] Electrodes 12, symmetrically arranged in the cavity of the bottom plate 11 and connected to a power supply for limiting and conducting electricity to the workpiece to be detected. The two electrodes 12 are respectively connected to the positive and negative poles of the power supply through wires. Of course, a frequency converter and a transformer should also be electrically connected between the wires and the electrodes 12 to adjust the voltage and / or frequency between the two electrodes 12; the voltage and / or frequency in contact with the insulation material can be adjusted, making it closer to the actual working environment, and the voltage and / or frequency can be adaptively adjusted according to different insulation materials, with a wider application range. The frequency converter and the transformer are existing well-known technologies, and specific specifications are not limited too much here;

[0030] A groove 13 is formed on one side of the electrode 12. The groove 13 includes a rectangular first clamping groove and a circular second clamping groove. The first clamping groove communicates with the second clamping groove. By setting the first clamping groove, a rectangular block-shaped workpiece to be detected is clamped and limited, while the second clamping groove clamps a cylindrical workpiece, further improving the adaptability.

[0031] As Figure 2 , Figure 3 and Figure 4 shown, an adjusting structure is provided above the bottom plate 11 for adjusting the distance between the two electrodes 12. The adjusting structure includes a detection table 20, a push plate 21 and sliding blocks 22. The detection table 20 is fixedly connected to the bottom plate 11. A plurality of sliding blocks 22 are slidably arranged on the top of the detection table 20. The push plate 21 is elastically connected to the sliding blocks 22. The electrode 12 is fixedly arranged on one side of the push plate 21. A lead screw is provided on the wall surface of the detection table 20 to drive the two electrodes 12 to move towards each other. The adjusting structure further includes sliding channels 23. Two sliding channels 23 are formed on the top of the detection table 20. Two sliding blocks 22 are slidably connected in each sliding channel 23. The push plate 21 is respectively connected to the sliding blocks 22 in the two sliding channels 23. The sliding blocks 22 form a block structure. The sliding channels 23 and the sliding blocks 22 are used in cooperation. A threaded hole is formed on the wall surface of the sliding block 22. The lead screw is threadedly connected to the sliding block 22. A rotating shaft is fixedly installed on the inner wall surface of the detection table 20 at the position of the sliding block 22. The lead screw is fixedly connected to the inner ring of the bearing. A motor is fixedly installed on the wall surface of the detection table 20. The other end of the lead screw is fixedly connected to the output shaft of the motor. In this solution, by setting the detection table 20, by connecting the motor to the power supply, the motor drives the lead screw to rotate, and the lead screw moves the two sliding blocks 22 closer to each other. Then the two push plates 21 move closer to each other and the electrode 12 clamps the workpiece. The electrode 12 can keep in close contact with the workpiece, thus ensuring the conductive effect, increasing the adaptation range of the workpiece length, reducing the probability that the insufficient contact between the workpiece and the electrode 12 affects the conductivity, and improving the detection accuracy.

[0032] As Figure 5As shown in the figure, the adjusting structure further includes a connecting block 30 and a limiting groove 31. The top of the sliding block 22 is engaged with the limiting groove 31. The connecting block 30 is located in the limiting groove 31. An elastic member is provided in the limiting groove 31 to push the connecting block 30 to slide. The push plate 21 is fixedly connected to the connecting block 30. The limiting groove 31 is a rectangular groove, and the connecting block 30 is a rectangular block. The connecting block 30 is slidably connected to the limiting groove 31. The elastic member includes a spring but is not limited to a spring. The two ends of the spring are respectively fixedly connected to the connecting block 30 and the sliding block 22. As a supplement to the above solution, when the two electrodes 12 approach each other to clamp the workpiece, the push plate 21 can push the connecting block 30 to slide in the limiting groove 31 and compress the spring, realizing the elastic connection between the push plate 21 and the sliding block 22, so that the two electrodes 12 can both elastically clamp the workpiece and hard-contact clamp it. During the process of the electrodes 12 clamping the workpiece, the clamping surface of the workpiece can be fully attached to the attaching surface of the electrodes 12. Secondly, when detecting workpieces with similar sizes, the two push plates 21 can be pushed away from each other, and the workpiece can be placed between the two electrodes 12 to achieve clamping and fixing, which is more convenient and efficient, and there is no need to repeatedly start and stop the motor to drive the screw to rotate.

[0033] The working principle of the present invention: The two electrodes 12 are respectively connected to the positive and negative electrodes of the power supply through wires. Of course, a frequency converter and a transformer should also be electrically connected between the wires and the electrodes 12 to adjust the voltage and / or frequency between the two electrodes 12; the voltage and / or frequency in contact with the insulating material can be adjusted to be closer to the actual working environment.

[0034] Connect the motor to the power supply. The motor drives the screw to rotate. The screw moves the two sliding blocks 22 closer to each other. Then the two push plates 21 move closer to each other and the electrodes 12 clamp the workpiece. The electrodes 12 can maintain close contact with the workpiece to ensure the conductive effect. When the two electrodes 12 approach each other to clamp the workpiece, the push plate 21 can push the connecting block 30 to slide in the limiting groove 31 and compress the spring, realizing the elastic connection between the push plate 21 and the sliding block 22, so that the two electrodes 12 can both elastically clamp the workpiece and hard-contact clamp it. During the process of the electrodes 12 clamping the workpiece, the clamping surface of the workpiece can be fully attached to the attaching surface of the electrodes 12. When detecting workpieces with similar sizes, the two push plates 21 can be pushed away from each other, and the workpiece can be placed between the two electrodes 12 to achieve clamping and fixing.
