Description

Technical Field

[0001] This utility model relates to the field of insulator airtightness testing technology, and in particular to a three-phase box-type insulator airtightness testing tooling vehicle device. Background Technology

[0002] Metal-enclosed gas-insulated switchgear (GIS) boasts advantages such as compact structure, small footprint, high reliability, flexible configuration, convenient installation, strong safety, and strong environmental adaptability. Therefore, it is widely used in high-voltage, ultra-high-voltage, and extra-high-voltage fields. Three-phase common-enclosure basin insulators, as a crucial component of GIS, play a vital role in isolating the gas chamber and supporting the conductors. During the manufacturing process of three-phase common-enclosure basin insulators, airtightness testing fixtures are required. However, when these fixtures are used, inconsistent torque application can lead to air leakage. Furthermore, poor demolding processes in three-phase common-enclosure basin insulators can cause basin friction and other problems, resulting in equipment discharge and insufficient airtightness. Summary of the Invention

[0003] The purpose of this invention is to provide a three-phase box-type insulator airtightness testing tooling vehicle to solve the technical problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This utility model discloses a three-phase box-type insulator airtightness testing fixture vehicle device, including a bracket, on which an airtight fixture is rotatably mounted. A handle wheel for driving the airtight fixture to rotate is provided on the outside of the bracket. An air inlet valve and a pressure gauge connected to the inside are provided oppositely on the outer wall of the airtight fixture. Two three-phase box-type insulators to be tested are symmetrically arranged on both sides of the airtight fixture. Pressure plates for fixing the two three-phase box-type insulators are detachably mounted on the outer side of each of the two three-phase box-type insulators.

[0006] Furthermore, each end of the airtight fixture is fixedly provided with a rotating shaft, and the two rotating shafts are respectively rotatably connected to the first mounting sleeve and the second mounting sleeve fixedly provided at both ends of the top of the bracket.

[0007] Furthermore, a screw is fixedly connected to the free end of the rotating shaft that is rotatably connected to the second mounting sleeve. A threaded hole adapted to the screw is opened in the middle of the handle wheel. A slide seat that slides with the screw is provided between the handle wheel and the second mounting sleeve. A limiting boss adapted to the limiting groove opened on the second mounting sleeve is provided on the slide seat.

[0008] Furthermore, the airtight fixture has a plurality of screws evenly arranged around its circumference near its outer edge. Each screw passes through the through hole in the three-phase box basin insulator and the pressure plate. Each screw is provided with a matching fastening nut at the part of its outer side on the pressure plate.

[0009] Furthermore, the pressure plate is made of a hard metal plate.

[0010] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0011] This invention connects the pressure plate, airtight fixture, and support together with the three-phase common-box basin insulator to be tested. The insulator is filled with the appropriate gas as specified, and the pressure gauge is checked for depressurization within a specified time to determine whether the airtightness of the three-phase common-box basin insulator is qualified. Therefore, this invention can quickly test the airtightness of three-phase common-box basin insulators, ensuring surface quality during the testing process, and features simple structure, stable performance, and convenient operation.

[0016] like Figures 1-2 As shown, a three-phase box-type insulator airtightness testing fixture vehicle device includes a bracket 1, on which an airtight fixture 2 is rotatably mounted. Specifically, two ends of the airtight fixture 2 are respectively fixedly provided with rotating shafts 3, and the two rotating shafts 3 are respectively rotatably connected to a first mounting sleeve 4 and a second mounting sleeve 5 fixedly provided at both ends of the top of the bracket 1.

[0017] The bracket 1 is externally mounted with a handle wheel 6 for driving the airtight fixture 2 to rotate. In this embodiment, a screw 7 is fixedly connected to the free end of the rotating shaft 3, which is rotatably connected to the second mounting sleeve 5. A threaded hole adapted to the screw 7 is provided in the middle of the handle wheel 6. A slide block 8 that slides with the screw 7 is installed between the handle wheel 6 and the second mounting sleeve 5. The slide block 8 is provided with a limiting boss 9 that is adapted to the limiting groove opened on the second mounting sleeve 5.

[0018] An air inlet valve 10 and a pressure gauge 11, which are connected to the interior of the airtight fixture 2, are installed opposite each other on the outer wall of the fixture.

[0019] The airtight fixture 2 has two symmetrically and detachably mounted three-phase box-type insulators 12 to be tested on both sides. Each of the two three-phase box-type insulators 12 has a detachably mounted pressure plate 13 for fixing it. Specifically, multiple screws are evenly arranged circumferentially near the outer edge of the airtight fixture 1. Each screw passes through a through hole in both the three-phase box-type insulator 12 and the pressure plate 13. A matching fastening nut 14 is installed on the outer part of each screw on the pressure plate 13. In this embodiment, the pressure plate 13 is made of rigid metal plate.

[0020] The working principle of this utility model is as follows:

[0021] First, align the three-phase common-box basin insulator to be tested with the dedicated airtight fixture on the support. Then, use a pressure plate and multiple fastening nuts to fix the three-phase common-box basin insulator to the airtight fixture. This invention allows for the installation of two three-phase common-box basin insulators on both sides of the airtight fixture. After installing one side as described above, with the screw fixed, rotate the handle wheel threaded to the screw. The handle wheel will rotate outward, and then the slide block slidably connected to the screw will be moved outward, disengaging the slide block from the engagement with the second mounting sleeve. Then, the workers will rotate the handle wheel and screw together, flipping the side of the airtight fixture where the three-phase common-box basin insulator will be installed to a horizontal position. At this point, move the slider again to engage the limiting boss with the limiting groove on the second mounting sleeve, and tighten the handle to lock the airtight fixture, allowing for the safe installation of the three-phase common-box basin insulator to be tested.

[0022] After the three-phase box-type insulators on both sides of the airtight fixture are installed, turn the handle wheel out again and move the slide block in the same way as before to flip the entire airtight fixture to a vertical position. Then turn the slide block back and tighten the handle wheel to prevent the airtight fixture from rotating randomly during operation and avoid accidents.

[0023] During testing, the corresponding inflation / deflation device is connected via the inlet valve, and the entire device is covered with a mesh cover to prevent accidents during filling. Gas is filled and deflated according to the product specifications. Once the pressure gauge reaches the specified pressure, the inlet valve and the deflation device are immediately closed. The pressure gauge reading is monitored for changes over a specified time. If the pressure decreases, a leak detector is immediately used to check the center conductor and the area around the pressure plate of the three-phase common-box basin insulator, checking each potential leak point to take appropriate leak detection measures before proceeding to the next step.

[0024] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
