[0021] The following further describes in detail the embodiments of the present utility model in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the technical solutions of the present utility model, but cannot be used to limit the protection scope of the present utility model.

[0022] Embodiment:

[0023] As Figure 1 , 2As shown in the figure, the utility model provides a mutual inductor detection fixture, which includes a support table 11. Above the support table 11, two groups of fixing components are arranged. The mutual inductor is clamped between the two groups of fixing components, so as to ensure that it can maintain a stable state during subsequent operations. The fixing component includes two groups of claws 21. A plurality of chutes 12 are opened on the support table 11. One end of the claw 21 is provided with a clamping block 22, and the clamping block 22 can be clamped in the chute 12. The claw 21 is slidably connected to the support table 11, and the claw 21 can slide freely within the range defined by the chute 12 to adapt to the fixing requirements of mutual inductors of different sizes, which not only provides flexibility but also increases the convenience of operation. At the same time, a support frame 13 is also arranged on the support table 11, and a control panel 31 is installed on the support frame 13. Through the control panel 31, the operator can conveniently control and monitor the entire detection process and understand the detection status and parameters in real time.

[0024] The fixing component further includes two groups of lead screws 23. Bearings are arranged at both ends of the chute 12, and both ends of the lead screw 23 are inserted into the bearings, so that the lead screw 23 can rotate smoothly with the assistance of the bearings. A through hole is opened on the clamping block 22, and the clamping block 22 is sleeved on the lead screw 23 through this through hole, so that the claw 21 is slidably connected to the lead screw 23. This makes it possible for the claw 21 to move and enables it to adjust its position according to actual needs. One end of the lead screw 23 is provided with a connecting wheel 24, and the two connecting wheels 24 are connected by a transmission belt 25. The presence of the transmission belt 25 ensures that the two connecting wheels 24 can cooperate to achieve force transmission and movement synchronization. Mounting plates 26 are arranged at both ends of the support table 11, and a motor is installed on the mounting plate 26, and the shaft end of the motor is closely connected to one of the connecting wheels 24. When the motor is started, its power is transmitted to the connecting wheel 24 through the shaft end, and then the two lead screws 23 are driven to rotate synchronously through the transmission belt 25. The claw 21 can then move smoothly along the chute 12 under the drive of the lead screw 23 to achieve the clamping or loosening action of the mutual inductor.

[0025] At the same time, a rubber pad 27 is arranged on one side of the claw 21. When the claw 21 fixes the mutual inductor, the rubber pad 27 will be in direct contact with the mutual inductor, which can not only increase the friction force to make the fixation of the mutual inductor more stable and reliable, but also play a certain buffering role to avoid damaging the mutual inductor during the fixation process.

[0026] As Figures 2 to 4As shown, an installation groove 14 is formed on the support platform 11, and a magnet plate 32 is disposed above the support platform 11. The magnet plate 32 is clamped in the installation groove 14, so that the magnet plate 32 can be stably placed on the support platform 11. At the same time, a through groove 15 is also formed on the support platform 11. The connecting seat 33 is clamped in the through groove 15, and through the fastening action of screws, the connecting seat 33 is firmly connected to the support platform 11. The connecting seat 33 contacts the magnet plate 32 to form a good conduction path. Through a wire, the connecting seat 33 can be smoothly connected to an external power supply, so as to ensure that current can be smoothly transmitted to the magnet plate 32, enabling it to exert its due magnetic force effect.

[0027] A gantry 34 is disposed above the support platform 11. Multiple groups of connection holes are formed on both the gantry 34 and the support platform 11, and connecting bolts are clamped in these connection holes, so that the gantry 34 is detachably connected to the support platform 11, providing great convenience for subsequent maintenance and adjustment. Multiple groups of scanning cameras 35 are disposed on the gantry 34. The scanning cameras 35 can adopt Uniview IPC-B2A2-IR infrared cameras. The scanning cameras 35 can perform real-time monitoring and scanning of the transformer and the surrounding environment in all directions, collect important data and information, and provide strong support for subsequent analysis and judgment. In addition, a card slot is formed on the support platform 11, and multiple groups of maintenance plates 36 are disposed above the support platform 11. The maintenance plates 36 are clamped in the card slot, and are further fastened through connecting screws. The clamping block 22 can pass through the maintenance plate 36 and be clamped in the sliding groove 12, which not only ensures the rationality of the structure, but also provides a more stable and reliable guarantee for the fixation and operation of the transformer.

[0028] The specific usage mode and function of this embodiment:

[0029] First, place the mutual inductor at the position between the two sets of fixing components on the support table 11. Start the motor, and the power of the motor is transmitted to the connecting wheel 24 through the shaft end, and then drives the two sets of lead screws 23 to rotate synchronously through the transmission belt 25, so that the claw 21 moves smoothly along the chute 12 under the drive of the lead screw 23 to realize the clamping action of the mutual inductor. At this time, the rubber pad 27 is in direct contact with the mutual inductor, increasing the friction and playing a buffering role. Then, through the control panel 31, the entire detection process can be conveniently controlled and monitored, and the status and parameters of the detection can be understood in real time. During the detection process, the Hikvision IPC-B2A2-I R infrared camera on the gantry 34 will monitor and scan the mutual inductor and the surrounding environment in all directions in real time, collect relevant data and information, and provide strong support for subsequent analysis and judgment. When maintenance or adjustment of the device is required, the gantry 34 can be removed from the support table 11 by removing the connecting bolts, facilitating subsequent operations. If the mutual inductor needs to be repaired, the repair board 36 can be clamped in the card slot and fastened by connecting screws, so that the card block 22 can pass through the repair board 36 and be clamped in the chute 12 to ensure the smooth progress of the repair work. Finally, through the cooperation of the connecting seat 33 and the magnet plate 32, the smooth transmission of the current and the normal exertion of the magnetic force of the magnet plate 32 are guaranteed.

[0030] The above shows and describes the basic principles, main features and advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments.
