[0029] like Figure 1-Figure 5The technical solution shown includes a frame 1, a test box 3 is installed on the frame 1, a test table 4 is arranged inside the test box 3, and an auxiliary component is arranged under the test table 4. The auxiliary component includes a sleeve 5 installed under the test table 4, and a telescopic cylinder 6 is arranged at the bottom of the sleeve 5. A tooth block 7 is installed on the side wall of the sleeve 5, and a gear 8 is meshed and connected to the side end of the tooth block 7. The gear 8 is symmetrically arranged, and the gear 8 is connected to the inside of the test box 3 through a support seat 9. A bracket 10 is installed on the gear 8, and an electromagnetic seat 11 is clamped at the end of the bracket 10. A detection piece 12 is installed on the electromagnetic seat 11, which is adsorbed on the iron casing of the transformer through the electromagnetic seat 11 of the auxiliary component, and the detection piece 12 is used for vibration detection. Open the test box 3 on the frame 1, and place the transformer to be tested on the test table 4. The test box 3 is symmetrically arranged, so it is not only convenient for multiple transformers to be tested, which improves the efficiency of the overall test, but also convenient for later comparative testing, which improves the overall practicality. At this time, the telescopic cylinder 6 is retracted, so that the sleeve 5 drives the detection platform 4 to descend, so that the tooth block 7 on the outside of the sleeve 5 drives the gear 8 to rotate on the support seat 9, thereby driving the bracket 10 to rotate. At this time, the symmetrically arranged bracket 10 moves toward the side end of the transformer. At this time, the electromagnetic seat 11 is energized, so that the electromagnetic seat 11 can be adsorbed on the iron casing of the transformer, so as to facilitate the detection of the detection piece 12 on the side end of the electromagnetic seat 11, so that the overall detection rigor is greatly improved. And the detection piece 12 is adsorbed on the transformer through the electromagnetic seat 11 for detection, which reduces the problem of reduced detection reliability caused by external detection, and the bracket 10 and the electromagnetic seat 11 are convenient for clamping. Therefore, after the overall detection, the bracket 10 can be clamped with the electromagnetic seat 11, and the electromagnetic seat 11 is turned off after being fixed, so that the electromagnetic seat 11 and the iron casing of the transformer are no longer adsorbed, so that the electromagnetic seat 11 can be rotated through the bracket 10, which is convenient for the rapid installation and disassembly of the detection piece 12.

The filter box 17 in the auxiliary box 2 filters the air, and the clean gas is transported to the first storage box 19 and the second storage box 20 through the transmission pipeline 18, which is convenient for cleaning the inside of the detection box 3, reducing the problem of the detection being affected by the dust inside the detection box 3, and the transported clean gas is convenient for later use, which improves the overall practicality. The double-axis motor 22 inside the protective cover 21 is opened, and the double-axis motor 22 is convenient for driving the forward and reverse screws 23 to rotate, so that the moving plate 24 on the forward and reverse screws 23 moves through the guide rod 25, and the moving plate 24 drives the piston 26 to move inside the temporary storage tube 27, so that the gas inside the temporary storage tube 27 is transported, which is convenient for later comparative detection and improves the overall detection efficiency. The double-axis motor 22 is convenient for driving the symmetrically arranged temporary storage tube 27 for use, so that the overall driving efficiency is greatly improved, and the problem of the need to set more driving structures leading to an increase in overall cost is reduced. The structure is simple, which makes the overall operation convenient, and reduces the problem of increasing maintenance costs due to setting a complex structure for driving.

[0032] Embodiment three: In this embodiment, in order to facilitate the adjustment of the temperature inside the detection box 3 so that the overall comparative detection can be conveniently performed, a gas transmission component is provided for use, the purpose of which is to evaluate the impact of temperature on the vibration characteristics of the transformer, thereby providing a basis for maintenance and optimization of the equipment.

[0033] Specific as Figure 2 , Figure 6 , Figure 7 and Fig.10 As shown, the input end of the temporary storage cylinder 27 is connected to a gas delivery assembly, which includes a first pipeline 28 installed at the input end of the temporary storage cylinder 27, the end of the first pipeline 28 is connected to a second pipeline 29 and a third pipeline 31, valves are provided on the second pipeline 29 and the third pipeline 31, the second pipeline 29 is connected to the inside of the second storage box 20, a heating element 30 is provided inside the second storage box 20, the third pipeline 31 is connected to the inside of the first storage box 19, a refrigeration element 32 is provided inside the first storage box 19, the output end of the temporary storage cylinder 27 is connected to a fourth pipeline 33, the fourth pipeline 33 is connected through the inside of the detection box 3, a nozzle 34 is installed on the fourth pipeline 33, a driving shaft 36 is connected to the forward and reverse screws 23 through a driving element 35, an eccentric wheel 37 is installed on the outside of the driving shaft 36, the eccentric wheel 37 is rotated and contacts with a filter plate 38, the filter plate 38 is connected to the inside of the filter box 17 through a shaking assembly, and the shaking assembly includes a connection The slider 39 at the end of the filter plate 38 is sleeved on the slide bar 42, and the slide bar 42 is installed inside the storage groove 40.
