[0019] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0020] The transformer detection device according to the embodiment of the present invention will be described below with reference to the accompanying drawings.

[0021] The transformer detection device provided in the embodiment of the present invention can be used in the transformer assembly process to detect whether the noise and vibration conditions in the transformer meet the product field standards, and can assist relevant personnel to quickly locate the problem location and save maintenance time.

[0022] like Figure 1 , Figure 2 and Figure 5 As shown, the transformer detection device according to the embodiment of the present invention may include a limit component 1, a position adjustment component 2, a noise detection component 3 and a vibration detection component 4, wherein the limit component 1 is used to limit the transformer to be detected.

[0023] The position adjustment component 2 may include: a circular drive component 21 and a vertical drive component 22, wherein the circular drive component 21 is arranged above the limit component 1, the vertical drive component 22 is arranged on the circular drive component 21, the vertical drive component 22 is provided with a horizontal drive component 23, the horizontal drive component 23 is provided with a rotating device 24, and the noise detection component 3 is arranged on the rotating device 24.

[0024] It should be noted that the vertical drive assembly 22 described in this embodiment may adopt a ball screw pair drive structure, such as Figure 6 As shown, the vertical drive assembly 22 may include: a first warehouse body, a first drive motor, a first ball screw, a first ball slider and a first slide, the first drive motor is arranged on the first warehouse body, the first ball screw is arranged on the first drive motor, the first ball slider is arranged on the first ball screw, the first slide is slidably connected with the first warehouse body, and the first slide is connected with the first ball screw, and the horizontal drive assembly 23 is arranged on the first slide. The first drive motor drives the first ball screw to rotate, so that the first ball slider drives the horizontal drive assembly 23 (for example, a hydraulic telescopic machine) to move vertically through the first slide.

[0025] The position adjustment component 2 is configured to adjust the distance between the noise detection component 3 and various components of the transformer to be tested, so that the noise detection component 3 can detect multiple noise sources respectively.

[0026] It can be understood that the mutual cooperation of the quality inspection of the annular drive component 21, the vertical drive component 22, the horizontal drive component 23, and the rotating device 24 described in this embodiment can enable the noise detection component 3 to move to different positions around the transformer to be tested, so as to perform more comprehensive noise detection on the transformer to be tested and obtain more comprehensive detection data, which is convenient for relevant personnel to judge the fault location.

[0027] The vibration detection component 4 is arranged on the vertical driving component 22 and is used to detect the amplitude of the transformer to be tested.

[0028] It can be understood that the vibration detection component 4 described in this embodiment can detect the vibration amplitude of the transformer to be tested in multiple directions (for example, the vertical direction of the Z axis and the two lateral directions of XY) during the process of noise detection.

[0029] In order to clearly explain the above embodiment, in one embodiment of the present invention, as Figure 2-Figure 4 As shown, the limiting assembly 1 may include: a workbench 11 and a plurality of clamping members 12, the plurality of clamping members 12 are respectively arranged on the workbench 11, and the clamping members 12 may include: a hydraulic telescopic device 121, a fixed bin 122, a back plate 123, an elastic member 124, a plurality of rollers 125 and an electromagnet 126.

[0030] Among them, the hydraulic telescopic device 121 is arranged on the workbench 11, the fixed bin 122 is arranged at the telescopic end of the hydraulic telescopic device 121, the abutment plate 123 is in contact with the fixed bin 122, one end of the elastic member 124 is arranged in the fixed bin 122, and the other end of the elastic member 124 is connected to one side of the abutment plate 123. An installation groove 127 is opened on the other side of the abutment plate 123, and a plurality of roller bodies 125 are rotatably arranged in the installation groove 127. The electromagnet 126 is arranged in the installation groove 127, and the electromagnet 126 is magnetically connected to the plurality of roller bodies 125.

[0031] It should be noted that the clamping member 12 described in this embodiment can adopt different limiting methods according to different working requirements.

[0032] When the transformer to be tested needs to be stably clamped, the hydraulic expansion device 121 can drive the elastic member 124 to move the abutment plate 123 through the fixed chamber 122. After the abutment plate 123 abuts against the transformer to be tested, the fixed chamber 122 continues to move, and the fixed chamber 122 continues to press the elastic member 124 until the fixed chamber 122 slightly abuts against the abutment plate 123, so as to complete the clamping of the transformer to be tested. The provision of the elastic member 124 reduces the probability of over-clamping the transformer, thereby causing unnecessary damage to the transformer and the abutment plate 123.

[0033] When the vibration condition needs to be tested, the telescopic end portion of the hydraulic telescopic device 121 on the corresponding clamping member 12 retracts to separate the abutment plate 123 from the fixed bin 122. Under the action of the elastic member 124, the abutment plate 123 can still abut against the transformer to be tested, and the electromagnet 126 is controlled to lose magnetism so that the roller body 125 can roll freely. The elastic member 124 pushes the abutment plate 123 to abut against the transformer to prevent excessive vibration amplitude caused by transformer failure during the detection process, so as to cause a large displacement of the transformer on the workbench and damage other components.

[0034] It should be noted that when only the vibration condition in the vertical direction of the Z-axis is detected, the position of the hydraulic telescopic device 121 remains unchanged, and the abutment plate 123 can be completely separated from the transformer as needed, but the position of the abutment plate 123 can still limit the maximum moving distance of the transformer, and the elastic member 23 can be a spring, and multiple elastic members 23 can be provided.

[0035] In one embodiment of the present invention, Figure 5 and Fig. 9As shown, the vibration detection component 4 may include: a first electric telescopic rod 41, a second electric telescopic rod 42, a first motor 43 and a contact vibration detection device 44, wherein the first electric telescopic rod 41 is arranged on the vertical drive component 22, the second electric telescopic rod 42 is connected to the telescopic end of the first electric telescopic rod 41 through a connecting rod 45, the first electric telescopic rod 41 is configured to control the vertical movement of the second electric telescopic rod 42, and the telescopic end of the second electric telescopic rod 42 is provided with a first motor 43, the second electric telescopic rod 42 is configured to control the horizontal movement of the first motor 43, and the contact vibration detection device 44 is arranged on the driving end of the first motor 43.

[0036] It can be understood that the first electric telescopic rod 41 described in this embodiment is arranged on the first slide, the first electric telescopic rod 41 can drive the second electric telescopic rod 42 to move vertically through the connecting rod 45, the second electric telescopic rod 42 can drive the first motor 43 to move horizontally, and the first motor 43 can drive the contact vibration detection device 44 to rotate to adjust the working position of the contact vibration detection device 44.

[0037] In one embodiment of the present invention, Figure 5 , Figure 7 and Figure 8 As shown, the rotating device 24 may include: a mounting frame 241 and a second motor 242, the mounting frame 241 is arranged on the horizontal driving assembly 23, the second motor 242 is arranged on the mounting frame 241, and the noise detection assembly 3 is arranged at the driving end of the second motor 242, wherein the horizontal driving assembly 23 is configured to drive the mounting frame 241 to move horizontally. The annular driving assembly 21 includes: an annular guide rail 211 and an electric trolley 212, wherein the annular guide rail 211 is arranged above the limiting assembly 1, the electric trolley 212 is arranged on the annular guide rail 211, and the vertical driving assembly 22 is arranged on the electric trolley 212 (the first bin body is fixedly arranged on the electric trolley 212).

[0038] It can be understood that the horizontal driving assembly 23 described in this embodiment can adopt a hydraulic telescopic machine to drive the mounting frame 241 to move horizontally.

[0039] Specifically, after the relevant personnel have completed the assembly of the iron core and the winding on the workbench 11, they limit the assembled transformer on the workbench 11 through the limit assembly 1 and start noise detection. The electric trolley 212 can move along the annular guide rail 211. The electric trolley 212 can drive the vertical drive assembly 22 to move. The vertical drive assembly 22 can drive the mounting frame 241 to move horizontally through the horizontal drive assembly 23. The second motor 242 drives the noise detection assembly 3 to rotate. By adjusting the working position of the noise detection assembly 3, noise detection can be performed on different positions of the transformer.

[0040] The reason why the iron core produces noise is that there is electromagnetic attraction between the joints of the iron core silicon steel sheets and the laminations due to leakage magnetic field. Under the action of the alternating magnetic field, slight changes will occur, causing the iron core to vibrate periodically with the change of the excitation frequency, thereby generating noise. The reason why the winding vibrates is that the electromagnetic force is generated in the current winding. The leakage magnetic field can also cause the structural parts to generate noise. The noise detection component 3 is used to detect noise at different positions of the iron core and winding to obtain more accurate noise data. Relevant personnel can compare different noise data and determine the fault more quickly.

[0041] While performing noise detection, the first electric telescopic rod 41 can adjust the vertical position of the contact vibration detection device 44, and the second electric telescopic rod 41 can control the horizontal movement of the contact vibration detection device 44 so that the contact vibration detection device 44 contacts the transformer, and the contact vibration detection device 44 is driven to rotate by the first motor 43 to detect the vibration amplitude of the transformer in different directions.

[0042] It should be noted that the inspection can be carried out in sections during the assembly process. After the core and winding are assembled, an inspection can be carried out once, and then other components such as the housing and cooler can be inspected separately after installation.
