[0032] like Figures 1 to 5As shown, a component partial discharge test device provided by an embodiment of the utility model comprises: a box body 1, one end of the box body 1 is open, a box door 2 is hinged at the opening of the box body 1, the box body 1 and the box door 2 are both made of insulating materials to prevent leakage, a test device body 3 is arranged on one side of the box body 1, a screw guide rail 4 is arranged on one side of the box body 1, a detection head 5 is arranged at the movable end of the screw guide rail 4, and the detection head 5 is electrically connected to the test device body 3, a rotating assembly 6 is arranged at the bottom of the box body 1, and a tray 7 is detachably connected to the upper surface of the rotating assembly 6, and a plurality of groups of accommodating grooves 8 are arranged in a circumferential array on the surface of the tray 7. By removing the tray 7 from the rotating assembly The components to be tested are removed from the rotating assembly 6, and then the components to be tested are placed in multiple groups of receiving slots 8. Then the tray 7 is placed on the upper surface of the rotating assembly 6, and the box door 2 is closed to make the box body 1 a sealed environment. The movable end of the screw guide rail 4 drives the detection head 5 to move up and down to perform a partial discharge test on the components. After each group of components is tested, the rotating assembly 6 drives the tray 7 to rotate so that the next component to be tested is located directly under the detection head 5, thereby realizing continuous component testing, reducing the tedious work of detecting a group of components each time, and improving the efficiency of component detection. At the same time, the entire test process is in a sealed environment and will not be affected by the external environment, thereby ensuring the safety of the detection personnel.
[0033] The rotating component 6 includes a chassis 601, and a plurality of groups of support columns 602 are arranged on the lower surface of the chassis 601. One end of the plurality of support columns 602 is fixedly installed at the bottom of the box body 1, and the support columns 602 support the chassis 601. Two or more groups of support columns 602 can be arranged. A first groove 9 is opened on the upper surface of the chassis 601. The first groove 9 is arranged in an annular shape. A plurality of groups of rollers 603 are slidably connected in the first groove 9. A turntable 604 is fixedly installed at one end of the plurality of groups of rollers 603. The plurality of groups of rollers 603 support the turntable 604. At the same time, the plurality of groups of rollers 603 move in the annular first groove 9 to rotate the turntable 604. The rollers 603 reduce the friction in the first groove 9, so that the turntable 604 can rotate on the chassis 601. The tray 7 is detachably connected to the upper surface of the turntable 604.
[0034] A ring gear 605 is fixedly mounted on the lower surface of the rotating disk 604, and the ring gear 605 is meshed with a first gear 606. The first gear 606 is rotatably connected to the upper surface of the chassis 601, and the first gear 606 is meshed with a second gear 607. A rotating shaft 608 is fixedly mounted on one end of the second gear 607, and one end of the rotating shaft 608 passes through the chassis 601 and is rotatably connected to the bottom wall of the box body 1. A first bevel gear 609 is fixedly mounted on the surface of the rotating shaft 608, and the first bevel gear 609 is meshed with a second bevel gear 610. A motor 611 is fixedly mounted on one end of the second bevel gear 610. 611 is fixedly installed on the bottom wall of the box body 1. The second bevel gear 610 drives the first bevel gear 609 to rotate through the rotation of the output shaft of the motor 611. The rotating shaft 608 drives the second gear 607 to rotate synchronously. The first gear 606 meshing with the second gear 607 drives the ring gear 605 to rotate, so that the turntable 604 rotates. At the same time, multiple groups of rollers 603 move in the first groove 9, so that the tray 7 detachably connected to the upper surface of the turntable 604 rotates together, which is convenient for continuously switching the test objects during the test to carry out continuous tests to ensure the detection efficiency.
[0035] Two groups of slide grooves 10 are provided on the upper surface of the turntable 604, and a slider 11 corresponding to the slide groove 10 is fixedly installed on the lower surface of the tray 7. The slider 11 is slidably connected in the slide groove 10 to achieve a detachable connection between the tray 7 and the turntable 604, which makes it convenient to slide the tray 7 out from the upper surface of the turntable 604, replace the test components in the receiving slot 8, or prepare two groups of trays 7 to further improve the detection efficiency.
[0036] A second groove 12 is provided on the upper surface of the tray 7, and a third groove 13 is provided on the surface of the turntable 604. The second groove 12 and the third groove 13 are arranged correspondingly, and a through hole is provided in the second groove 12. A clamping block 14 is provided in the second groove 12, and one end of the clamping block 14 passes through the through hole and is clamped in the third groove 13. When the tray 7 and the turntable 604 are connected, they need to be fixed and positioned to prevent the detection head 5 from being offset from the component to be tested, or when the turntable 604 drives the tray 7 to rotate, the slider 11 slides out of a part of the slide groove 10, thereby causing inaccurate or untested tests. Therefore, the clamping block 14 is clamped in the third groove 13 to achieve fixation and positioning of the tray 7 and the turntable 604, to prevent the slider 11 from sliding out of a part of the slide groove 10 during the rotation of the turntable 604, causing the component to be tested on the tray 7 and the detection head 5 to be offset.
[0037] The clamping block 14 includes a clamping rod 1401, which is arranged in the second groove 12. A stopper 1402 is fixedly installed at one end of the clamping rod 1401. An arc groove is arranged in the third groove 13. The stopper 1402 is slidably connected to the arc groove. The clamping rod 1401 is inserted into the third groove 13 to fix and position the tray 7 and the turntable 604. However, during the transportation or conveying of the box 1, when the box 1 is in an inverted state, the tray 7 will be separated from the turntable 604. Therefore, the stopper 1402 is fixedly installed at one end of the clamping rod 1401. The clamping rod 1401 is rotated to slide the stopper 1402 into the arc groove, so that the tray 7 cannot be separated from the turntable 604 when the box 1 is inverted. At the same time, the stopper 1402 further improves the connectivity between the tray 7 and the turntable 604.
[0038] A blocking piece 1403 is provided at one end of the clamping rod 1401 , a spring 15 is fixedly installed in the second groove 12 , one end of the clamping rod 1401 passes through the hollow area of the spring 15 , and one end of the spring 15 is fixedly installed on the lower surface of the blocking piece 1403 .
[0039] A fourth groove 16 is provided on the lower surface of the chassis 601, and the fourth groove 16 is arranged in a ring shape. A plurality of groups of L-shaped blocks 17 are provided in a ring array on the surface of the turntable 604. A ball 18 is rotatably connected to one end of the L-shaped block 17, and the ball 18 is slidably connected to the fourth groove 16. The turntable 604 is tightly connected to the chassis 601 through the cooperation between the L-shaped block 17 and the ball 18. At the same time, during the rotation of the turntable 604, the ball 18 rotates in the fourth groove 16 without affecting the rotation of the turntable 604.
[0040] An observation port 19 is provided at one end of the box door 2, and an observation window 20 is embedded in the observation port 19. The observation window 20 is an explosion-proof window.
