[0019] Embodiments

[0020] As shown in Figure 1 The present application provides a coaxial cable slice sample insulation breakdown test rotary electrode device, specifically as follows:

[0021] The device base 1 is provided with a slide rail mechanism on the upper surface, two groups of slide table mechanisms are arranged on the slide rail mechanism, and electrode slide table modules 9 are arranged on the opposite sides of the two slide table mechanisms. The top of the two groups of slide table mechanisms is provided with a sample shaft support frame 14, and the sample shaft support frame 14 is arranged in the two sample shaft support frames 14. One end of the sample shaft 15 is connected to the motor mechanism through the telescopic fixing sleeve 19, and the sample mechanism is arranged on the sample shaft 15 and located between the two electrode slide table modules 9.

[0022] The horizontal slide rail track 2 of the slide rail mechanism is laid transversely, and the outer side is marked with a scale 4, which facilitates accurate measurement of the horizontal movement distance of the slide table mechanism. At both ends of the horizontal slide rail track 2, slide rail drive motors 5 are installed respectively to provide power for the horizontal movement of the slide table mechanism.

[0023] Each slide mechanism has a fixed slide rail base 6, on which a lead screw slide 7 and a wire drum 8 each play a role. The lead screw slide 7 is provided with a lead screw rail 13, and a rotating lead screw 24 is installed in the lead screw rail 13. The electrode slide module 9 is connected with the rotating lead screw 24, and when the rotating lead screw 24 rotates, the electrode slide module 9 can move vertically on the lead screw rail 13. The electrode slide module 9 contains a telescopic discharge electrode 10, and the top end of the discharge electrode 10 is provided with a discharge ball electrode 11 for discharging the sample, and the tail end of the electrode slide module 9 is provided with an electrode power input end 12 for connecting the power supply to supply power to the electrode. At the same time, the electrode power input end 12 at the tail end of the electrode slide module 9 is connected with the wire drum 8 through a wire, and the wire drum 8 plays a role in arranging and protecting the wire to prevent the wire from winding.

[0024] The sample mechanism is installed on the sample shaft 15, and the sample 18 is tightly clamped between the two sample fixing plates 16. At the connection between the sample fixing plates 16 and the sample shaft 15, a locking knob 17 is arranged, and by tightening the locking knob 17, the sample 18 can be ensured to be stable during the test. One end of the sample shaft 15 is connected with the motor mechanism through a telescopic fixing sleeve 19. The motor mechanism is installed on the motor support 20, and the motor support 20 is located on the upper surface of the device base 1. The rotating shaft motor 21 in the motor mechanism is the core driving component, and its operation drives the sample shaft 15 to rotate, and then the sample 18 rotates. In order to reduce the vibration generated when the rotating shaft motor 21 operates, a motor stabilizing ring 22 is installed on the rotating shaft motor 21. The motor support 20 is also provided with a control panel 23, which is convenient for the operator to start, stop and adjust the rotating speed of the rotating shaft motor 21 on the same side.

[0025] Working principle:

[0026] The utility model discloses the rotating shaft motor 21 drives the sample shaft 15 to rotate, and the sample 18 rotates, so that the different circumferential positions of the sample are exposed in turn under the electrode. At the same time, the telescopic discharge electrode 10 can move up and down, and can detect different height positions of the sample. The combination of the two realizes the comprehensive detection of different positions of the sample, and greatly expands the detection range.

[0027] After the slide rail driving motor 5 in the slide rail mechanism is started, the slide mechanism moves on the horizontal slide rail track 2, and the horizontal position adjustment of the electrode slide module 9 is realized. Inside the slide mechanism, the rotating lead screw 24 is rotated, and due to the limitation of the lead screw rail 13 of the lead screw slide 7, the electrode slide module 9 can only move vertically along the lead screw rail 13, so as to realize the vertical position adjustment of the electrode. The flexible adjustment in horizontal and vertical directions can quickly and accurately determine the detection point.

[0028] The sample 18 is clamped between two sample fixing plates 16, the sample fixing plates 16 are tightly fixed on the sample shaft 15 by screwing the locking knob 17, the sample is effectively prevented from shifting during the test, and the accuracy of the test result is ensured. The motor stabilizing ring 22 can reduce the vibration of the rotating shaft motor 21 during operation, thereby reducing the error in the test process.

[0029] Therefore, the coaxial cable slice sample insulation breakdown test rotating electrode device can comprehensively detect different positions of the sample through the rotation of the sample shaft and the up-down movement of the telescopic discharge electrode, greatly improving the detection range. The horizontal and vertical positions of the telescopic discharge electrode can be conveniently adjusted by using the sliding rail and the screw rod track, the detection point can be quickly and accurately determined, the test efficiency is improved, the overall stability of the device is enhanced, and the error in the test process is reduced.
