Description

Technical Field

[0001] This utility model relates to a thermal shock testing device for glass insulators, belonging to the field of thermal shock testing technology. Background Technology

[0002] In power systems, conductors need to be supported and stretched. To prevent current leakage, connecting components often need to be insulated. To further improve the safety level of power systems and their stability in harsh environments, glass insulators have gradually evolved. Glass itself is insulating and corrosion-resistant. Under certain special conditions, whether due to external environmental factors or localized discharge causing temperature changes, insulators need to be able to withstand sudden cooling and heating. Thermal shock testing equipment is used to simulate extreme temperature changes after insulator production to test the insulator's tolerance and ensure safety during use.

[0003] For example, Chinese utility model patent application CN202420516321.6 discloses a thermal shock testing device for glass insulators, comprising a housing and a heating chamber. The heating chamber is fixedly connected to the surface of the housing, and the heating chamber penetrates the surface of the housing and communicates with the interior of the housing. The surface of the housing is provided with a sealing device, and the surface of the heating chamber is provided with a clamping device. Multiple sets of heating rods are fixedly connected to the inner surface of the heating chamber. In this thermal shock testing device for glass insulators, through the cooperation of the clamping device and the sealing device, the output shaft of the second motor rotates, driving the threaded rod to rotate, allowing the platform to carry the glass insulator into the liquid inside the housing, so that the glass insulator can be tested. By reducing the heating space and improving the sealing performance, the energy consumption during heating can be reduced, while the heating speed can be increased, thus improving the working efficiency of the device.

[0004] The aforementioned document reduces energy consumption by shrinking the heating space where the insulator is located. During use, only the entire insulator is heated and then placed in a liquid for cooling. The test results are relatively simple, and when the temperature changes, only the overall change from hot to cold is observed. Utility Model Content

[0025] like Figure 3 As shown, the rotating device 2 includes a rotating motor 201 fixed to the bottom of the outer casing 1. The output shaft of the rotating motor 201 extends into the outer casing 1, and a lower plate 202 is rotatably engaged with the bottom of the outer casing 1. The bottom of the lower plate 202 is fixedly connected to the output shaft of the rotating motor 201. A support plate is fixed on the lower plate 202, and a bearing plate 203 is fixed on the top of the support plate. The bearing plate 203 has a receiving groove in the center and a protective net on it, which facilitates the stable placement of the insulator body 8. The insulator body 8 is placed on the bearing plate 203. Corresponding bottom holes are opened at the bottom of both the lower plate 202 and the outer casing 1. An input pipe connected to an external cold or heat source is provided on the side wall of the temperature regulating box 3, which facilitates the circulation of fluid.

[0026] like Figure 6 As shown, the limiting component 6 includes a cover 601 located above the insulator body 8. A vertical cylinder 602 is fixed to the top edge of the cover 601, and an inner cylinder 603 is fixed to the top of the cover 601. A buffer spring 604 is fixed to the bottom inside the inner cylinder 603, and a movable plate 605 is fixedly connected to the top of the buffer spring 604. The movable plate 605 and the bottom end of the lifting telescopic rod 5 are rotatably connected, which can better fix the insulator body 8 without affecting the rotation of the insulator body 8.

[0027] like Figure 4 , Figure 5 and Figure 7 As shown, the partition assembly 4 includes an edge plate 401 fixed to the bottom of the top plate 101, and a partition strip assembly 402 that can slide up and down in the passage strip hole. The partition strip assembly 402 is composed of interlocking partition strip individuals that can slide up and down. A soft strip 403 is fixedly connected to the bottom of the partition strip assembly 402. The soft strip 403 is made of strip-shaped heat insulation cloth wrapped with ceramic particles, which can facilitate the separation of temperature zones. The top of the partition strip assembly 402 extends above the top plate 101, and a protruding block 404 is individually fixed on the side wall of each partition strip individual, which can facilitate the raising of the height of the partition strip assembly 402.

[0028] like Figure 4 As shown, the control frame 7 includes an intermediate plate 701 fixed to the lifting telescopic rod 5. A lifting frame 702 is provided above the passage strip hole. The lifting frame 702 is located below the protruding block 404. An ear plate 703 is fixed on the side wall of the lifting frame 702.

During the test, the temperature control box 3 blows fluid of a specific temperature onto the insulator body 8, and the isolation component 4 effectively isolates the temperature range. After the temperature of the insulator body 8 stabilizes, the rotating device 2 quickly moves the insulator body 8 to another temperature range, thereby conducting a thermal shock test on the insulator body 8 to withstand sudden temperature changes.

[0030] In use, the protective door is opened, and the insulator body 8 is placed on the support plate 203. Then, the lifting telescopic rod 5 is lowered so that the cover 601 covers the insulator body 8. The cover 601 and the vertical cylinder 602 can provide a tight fit for the spacer strip group 402. Then, the cover 601 is pressed onto the insulator body 8. At this time, the control frame 7 is lowered, and the spacer strip group 402 follows. The soft strip 403 can fit and cover the outer wall of the insulator body 8. Then, different temperature control boxes 3 need to be connected to different temperature sources, which can be gas or liquid. After the fluid passes through the outside of the insulator body 8, it can directly change the local temperature of the insulator body 8. Then, the fluid can be discharged through the support plate 203 and the bottom hole at the bottom of the outer shell 1. In actual application, it can be fed back to the external temperature source for recycling. After the rotating motor 201 drives the insulator body 8 to rotate, it can carry the insulator body 8 to different temperature areas.
