DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the application will be described clearly and completely below with reference to the drawings in the embodiments of the application; obviously, the described embodiments are only part of the embodiments of the application, not all the embodiments of the application, and all other embodiments obtained by those skilled in the art without creative labor based on the embodiments in the application belong to the protection scope of the application.

[0025] As Figures 1-4 shown, the embodiment of the application discloses a novel aging test bench, which comprises a rack 10, and the rack 10 is provided with a test oil groove 20, a computer console 30 and a high-voltage generator 40.

[0026] The test oil groove 20 is provided with a fixed cover 50 and a sliding cover 60, the fixed cover 50 is arranged at the rear end of the test oil groove 20, and the sliding cover 60 is covered at the front end of the test oil groove 20 and slides along the front-rear direction.

[0027] During setup, the fixed cover 50 includes a top plate 51. Limiting strips 52 are provided at the bottom of the top plate 51 at the rear end and on both sides. The distance from the outer edge of the limiting strip 52 to the corresponding side edge of the top plate 51 is consistent with the thickness of the corresponding side of the top of the test oil tank 20. This ensures that the top plate 51 is precisely secured within the test oil tank 20 by the limiting strips 52. Two C-shaped retaining plates 53 are provided at the rear end of the top plate 51. The C-shaped retaining plates 53 and the rear end of the top plate 51 form insertion holes 54. Limiting pieces 55 are provided within the insertion holes 54. The lower end of the limiting pieces 55 abuts against the rear side wall of the test oil tank 20, preventing the top plate 51 from moving forward, thus fixing the top plate 51 horizontally to the rear end of the test oil tank 20. When it is necessary to disassemble or open the fixed cover 50, simply use a hoisting device to lift the fixed cover 50 upwards for easy disassembly.

[0028] The sliding cover 60 includes a cover plate 61 mounted on the test oil tank 20. Side plates 62 protrude downwards from both sides of the cover plate 61, and a fixing plate 63 is mounted at the bottom of the side plates 62. A slide rail 11 is mounted on each side of the test oil tank 20 on the frame 10. A sliding plate 13 is slidably mounted on the slide rail 11 via a slider 12. The fixing plate 63 on the sliding cover 60 is connected to the sliding plate 13 via a connecting plate 14, thus slidably connecting the sliding cover 60 to the slide rail 11. A handle is also provided on the sliding cover 60; manually pushing or pulling the handle allows the sliding cover 60 to slide on the slide rail 11, thereby opening or closing the test oil tank 20. The use of a push-pull structure with slide rail 11 for opening and closing the test oil tank 20 makes opening and closing the test oil tank 20 more convenient, eliminates the original counterweight structure, reduces safety risks, and saves space.

[0029] Furthermore, the high-voltage generator 40 adopts a split high-voltage power supply, including a control module and a voltage multiplier module. The control module is mounted on the frame 10 and connected to the computer control console 30 via a serial port for easier connection and operation. The voltage multiplier module is located inside the test oil tank 20, which effectively reduces the repeated insulation distance and thus effectively reduces the volume of the test oil tank 20. The control module and the voltage multiplier module are connected by a cable, and the cable is sealed where it passes through the test oil tank 20 to prevent leakage of insulating oil.

[0030] A filtering and cooling system is additionally arranged at the bottom of the test oil tank 20, that is, an oil outlet and an oil inlet are arranged at the bottom of the test oil tank 20, the oil outlet and the oil inlet are connected through a pipeline, and a filter 21, a circulating pump 22 and an air-cooled radiator 23 are sequentially arranged on the pipeline, the filter 21 filters the insulating oil from the test oil tank 20, the circulating pump 22 controls the circulating flow of the insulating oil in the whole filtering and cooling system, and the air-cooled radiator 23 cools the insulating oil filtered by the filter 21 to reduce the temperature of the insulating oil. Through the arrangement of the filter 21 and the air-cooled radiator 23, the insulating oil is filtered and cooled, and the electric insulation strength of the insulating oil in the test oil tank 20 can be effectively improved, and the qualified rate of product testing can be improved.

[0031] The preferred embodiments of the present application have been described above, the protection scope of the present application is not limited to the above-mentioned embodiments, any technical scheme falling within the idea of the present application belongs to the protection scope of the present application. It should be noted that, for ordinary skilled in the art, some improvements and decorations without departing from the principle of the present application are also considered as the protection scope of the present application.
