Description

Technical Field

[0001] This application relates to the field of electrical engineering technology, specifically a high-precision testing device for electrical engineering. Background Technology

[0002] Transformers are electrical engineering equipment and one of the core devices in the power system and electrical drive field. They play an important role in the power grid, and their operational reliability is directly related to the safety and stability of the power system. During maintenance, it is necessary not only to detect and analyze partial discharge, but also to inspect the transformer's appearance, such as checking for damage to its porcelain bushings, whether the connecting bolts of each part are secure, whether there is oil leakage at each interface, whether there is mechanical damage and corrosion on the surface, and whether the paint is intact. In the current technology, when inspecting transformers installed in high areas, workers are usually moved to the vicinity of the transformer by an aerial work platform, and then they conduct a comprehensive inspection with handheld testing tools. This is very inconvenient and has certain dangers.

[0003] For example, the patent document with announcement number CN118604542B discloses a testing fixture for transformers and rectifiers. When using this testing fixture, the operator can move the scissor lift onto an aerial work platform, which then carries the operator and the scissor lift to the vicinity of the transformer to be tested. The operator can then move the scissor lift directly opposite the transformer, turn the crank to rotate the lead screw, and under the action of the lead screw, the trapezoidal slide rod slides along the trapezoidal groove, ultimately bringing the contact ultrasonic sensor into contact with the transformer surface. After a period of time, the operator can observe the test results through a partial discharge detector. By moving and starting the scissor lift, the top mount can be moved in multiple directions (front, back, up, down), allowing the contact ultrasonic sensor to contact different locations on the transformer. As can be seen from the above description, the core logic of the existing technology is equipment carrying personnel plus manual operation. Essentially, it expands the range of human activity through the lift. The testing process relies entirely on personnel skills, requiring operators to be with the equipment at height throughout the entire testing process. Safety risks persist throughout the entire testing cycle, resulting in prolonged exposure time for personnel at the testing site. The testing process requires multiple independent manual operations, severely limiting efficiency and demanding a high level of proficiency in manual operation. Summary of the Invention

[0004] The purpose of this application is to provide a high-precision testing device for electrical engineering to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: A high-precision testing device for electrical engineering includes a body and a magnetic connection assembly. The magnetic connection assembly is installed in the middle of the body. The magnetic connection assembly includes a sleeve embedded in one side of the body. A magnetic shielding plate is horizontally placed in the middle of the sleeve. An electromagnet is installed at the top opening of the sleeve above the magnetic shielding plate, and a receiving plate is electrically connected to the bottom of the electromagnet. A power supply is fixedly installed on one side below the magnetic shielding plate, and the power supply is connected to a receiving cap through a wire. The receiving cap is sleeved on the top of an insulating rod, and the insulating rod slides with a through hole on the other side of the magnetic shielding plate through a spring. A cylindrical cam is rotatably installed at the bottom of the sleeve below the magnetic shielding plate, and the eccentric profile of the top of the cylindrical cam abuts against the bottom of the insulating rod. The bottom of the cylindrical cam has an indentation.

[0006] Furthermore, a lifting rod is detachably connected to the bottom of the machine body, and the top of the lifting rod is provided with a cross end that engages with the inlet, and a support plate is radially fixed to the top of the lifting rod.

[0007] Furthermore, the lifting rod is inserted into the bottom inlet of the cylindrical cam and rotated to cause the eccentric profile at the top of the cylindrical cam to drive the insulating rod to rise. After the electrical cap at the top of the insulating rod contacts the receiving plate, a power supply and electromagnet are established and the rod is attracted and fixed to the bottom of the transformer housing.

[0008] Furthermore, a rotary motor is fixedly installed on the other side of the machine body, and a drive gear is fixedly connected to the rotating end of the rotary motor.

[0009] Furthermore, a translation component is fitted outside the sleeve. The translation component includes a driven gear ring rotatably mounted outside the sleeve. The driven gear ring meshes with the outer teeth of the drive gear, and wing plates are radially fixed at both ends of the driven gear ring.

[0010] Furthermore, the translation component also includes a folding notch opened in the top opening of the wing plate, a translation motor is bolted to the outer end of the wing plate, and a lead screw is fixedly connected to the rotating end of the translation motor.

[0011] Furthermore, a lifting assembly is folded and installed inside the folding notch. The lifting assembly includes a slider that is threaded to the outside of a lead screw. The slider engages with the guide groove on the side wall of the wing plate, and shaft brackets are fixed on both sides of the top of the slider.

[0012] Furthermore, the lifting assembly also includes a limiting strip fixedly installed at the bottom of the opposite surfaces of the two end shafts, and a damping shaft is rotatably installed inside the two end shafts, with a flip plate coaxially fixed in the middle of the damping shaft.

[0013] Furthermore, the lifting assembly also includes a lifting motor bolted to the outer end of the flip plate. The rotating end of the lifting motor is fixedly connected to a lead screw, and the lead screw is externally threaded to a slider, which is limited to the guide groove on the inner wall of the flip plate.

[0014] Furthermore, the lifting assembly also includes detectors bolted to both ends of the slider. The detectors integrate an ultrasonic detection module and an appearance visual inspection module, and are positioned opposite each other on both sides of the transformer.

[0015] Beneficial effects; 1. In the application of this application, the core logic of the prior art is that the equipment carries people and the operation is manual. In essence, it expands the range of human activities through the lifting platform. The detection process depends entirely on human skills. However, this application constructs a new mode of mechanical carrier plus automatic execution. Through the mechanical structure of lifting rod lifting, electromagnet fixing and multi-motor drive adjustment, the detection tool is integrated into the self-adjustable flip plate and wing plate. There is no need for manual hand holding or contact with the detector. Then, the electromagnet automatically attracts and fixes the detector to replace manual alignment. The lead screw slider mechanism automatically adjusts the detection parameters, so that the machine can complete the core detection action for humans, fundamentally getting rid of the dependence on manual operation.

[0016] 2. Under the meshing transmission of the outer cylindrical teeth of the drive gear and the driven gear ring, the driven gear ring and its radially extending wing plates on both sides are driven to swing back and forth outside the sleeve, realizing the angular offset of the detector around the side of the transformer, covering the side peripheral area of ​​the cylindrical or polyhedral transformer. When it is necessary to adjust the distance between the detector inside the flip plate and the side of the transformer during use, the translation motor is activated and the lead screw is driven to rotate. Under the threaded action of the lead screw and the slider, the slider is driven to slide within the guide groove on the side wall of the wing plate, thereby realizing the dynamic adjustment of the distance between the detector inside the flip plate and the side of the transformer, adapting to transformers of different diameters and surface irregularities, and avoiding data distortion caused by collision or excessive distance during detection.

[0017] 3. This application achieves the adjustment of the detector's installation height within the flip plate by using the threaded engagement between the lead screw and the slider to limit the slider's movement within the guide groove on the inner wall of the flip plate. This covers the vertical area of ​​the transformer from top to bottom, enabling longitudinal inspection without the need for a complete relocation of the entire device. This application achieves full-surface inspection coverage of the transformer without blind spots through three-dimensional dynamic adjustment of rotation offset angle, spacing, and height. The above parameters can be adjusted in real time during the inspection process without interrupting the inspection flow, ensuring the continuity of data acquisition and avoiding blind spots or repeated inspections caused by downtime for adjustments, thereby improving inspection efficiency and accuracy.

[0027] Please see Figures 1 to 6 The high-precision testing device for electrical engineering provided in this application includes a body 1 and a magnetic connection component 2, wherein the magnetic connection component 2 is installed in the middle of the body 1; The magnetic connection assembly 2 includes a sleeve 201 embedded on one side of the body 1. A magnetic shielding plate 202 is horizontally placed in the middle of the sleeve 201. An electromagnet 203 is installed at the top opening of the sleeve 201 above the magnetic shielding plate 202. The bottom end of the electromagnet 203 is electrically connected to a receiving plate 204. A power supply 205 is fixedly installed on one side below the magnetic shielding plate 202. The power supply 205 is connected to a receiving cap 206 through a wire. The receiving cap 206 is sleeved on the top of the insulating top rod 207. The insulating top rod 207 slides with a through hole on the other side of the magnetic shielding plate 202 through a spring. A cylindrical cam 208 is rotatably installed at the bottom end of the sleeve 201 below the magnetic shielding plate 202. The eccentric profile at the top of the cylindrical cam 208 abuts against the bottom end of the insulating top rod 207. The bottom end of the cylindrical cam 208 is recessed and has an inlet 209.

[0028] A lifting rod 3 is detachably connected to the bottom of the body 1. The top of the lifting rod 3 is provided with a cross end 4 that engages with the inlet 209. A support plate 5 is radially fixed to the top of the lifting rod 3. The lifting rod 3 is inserted into the inlet 209 at the bottom of the cylindrical cam 208 and rotated to drive the insulating top rod 207 to rise due to the eccentric profile at the top of the cylindrical cam 208. After the top of the insulating top rod 207 is connected to the electric cap 206 and contacts the receiving plate 204, a power supply 205 and an electromagnet 203 are established and the power supply 205 is attracted and fixed to the bottom of the transformer housing.

[0029] In use, the flip plate 905 is first unfolded from the folding notches 803 of the two side wing plates 802. Then, the operator inserts the lifting rod 3 into the inlet 209 at the bottom of the cylindrical cam 208, and lifts the machine body 1 from the ground to a height by the end plate 5 of the lifting rod 3, until the electromagnet 203 at the top opening of the cylindrical cam 208 abuts against the bottom of the transformer housing. After that, the lifting rod 3 is rotated, and the cross end 4 engages with the groove in the inlet 209 to drive the eccentric contour at the top of the cylindrical cam 208 to lift the insulating top rod 207. Then, after the electric cap 206 at the top of the insulating top rod 207 contacts the receiving plate 204, a power supply 205 and electromagnet 203 are established and the electromagnet is attracted and fixed to the bottom of the transformer housing. In the whole process, the lifting position - mechanical triggering - energization and attraction form a closed loop. This integrated system eliminates the need for manual operation of the fixed device, completely transforming the traditional high-altitude inspection workflow. It achieves physical isolation between humans and hazardous environments. Existing technologies rely on equipment carrying personnel plus manual operation, essentially expanding the range of human activity through a lift. The inspection process is entirely dependent on human skills. This application, however, constructs a new model combining a mechanical carrier and automated execution. Through a mechanical structure involving lifting rod 3, fixing with electromagnet 203, and multi-motor drive adjustment, the inspection tool is integrated onto an adjustable flip plate 905 and wing plate 802. There is no need for manual handling or contact with the detector 909. The electromagnet 203 automatically adsorbs and fixes the detector, replacing manual alignment. The lead screw and slider mechanism automatically adjusts the inspection parameters, enabling the machine to complete the core inspection actions, fundamentally eliminating dependence on manual operation.

[0030] Please see Figure 7 A rotary motor 6 is fixedly installed on the other side of the body 1, and a drive gear 7 is fixedly connected to the rotating end of the rotary motor 6. A translation component 8 is sleeved on the outside of the sleeve 201. The translation component 8 includes a driven gear ring 801 rotatably installed on the outside of the sleeve 201. The driven gear ring 801 meshes with the outer teeth of the drive gear 7. Wing plates 802 are radially fixed at both ends of the driven gear ring 801. The translation component 8 also includes a folding notch 803 opened in the top opening of the wing plate 802. A translation motor 804 is bolted to the outer end of the wing plate 802, and a lead screw 805 is fixedly connected to the rotating end of the translation motor 804.

[0031] The rotary motor 6 is activated and drives the drive gear 7 to rotate. Under the meshing transmission between the outer circular teeth of the drive gear 7 and the driven gear ring 801, the driven gear ring 801 and its radially extending wing plates 802 on both sides are driven to swing back and forth outside the sleeve 201. This allows the detector 909 to shift its angle around the side of the transformer, covering the circumferential area of ​​the cylindrical or polyhedral transformer. When it is necessary to adjust the distance between the detector 909 inside the flip plate 905 and the side of the transformer during use, the translation motor 804 is activated and drives the lead screw 805 to rotate. Under the threaded engagement between the lead screw 805 and the slider 901, the slider 901 is driven to slide within the guide groove on the side wall of the wing plate 802, thereby realizing the dynamic adjustment of the distance between the detector 909 inside the flip plate 905 and the side of the transformer. This adapts to transformers of different diameters and surface irregularities, avoiding data distortion caused by collisions or excessive distance during detection.

[0032] Please see Figure 8 The folding notch 803 houses a lifting assembly 9, which includes a slider 901 threadedly connected to the outside of a lead screw 805. The slider 901 engages with a guide groove on the side wall of the wing plate 802, and shaft brackets 902 are fixed to both sides of the top of the slider 901. The lifting assembly 9 also includes limiting strips 903 fixedly installed at the bottom of the opposing surfaces of the shaft brackets 902. A damping shaft 904 is rotatably mounted inside the shaft brackets 902, and a flip plate 905 is coaxially fixed to the middle of the damping shaft 904. 9 also includes a lifting motor 906 bolted to the outer end of the flip plate 905. The rotating end of the lifting motor 906 is fixedly connected to a lead screw 907, and the lead screw 907 is externally threaded to a slider 908. The slider 908 is limited to the guide groove on the inner wall of the flip plate 905. The lifting assembly 9 also includes a detector 909 bolted to the end of the slider 908. The detector 909 integrates an ultrasonic detection module and an appearance visual inspection module. The detector 909 is disposed opposite to both ends of the transformer side.

[0033] The specific operation is as follows: When it is necessary to adjust the installation height of the detector 909 within the flip plate 905 during use, the lifting motor 906 is activated and drives the lead screw 907 to rotate. Under the threaded engagement of the lead screw 907 and the slider 908, the slider 908 is driven to slide within the guide groove on the inner wall of the flip plate 905, thereby adjusting the installation height of the detector 909 within the flip plate 905. This covers the vertical area of ​​the transformer from top to bottom, and longitudinal inspection can be completed without the need for the entire moving equipment. This application achieves full-surface inspection coverage of the transformer without dead angles through three-dimensional dynamic adjustment of rotation offset angle, dynamic adjustment of spacing, and precise adjustment of height. The above parameters can be adjusted in real time during the inspection process without interrupting the inspection process, ensuring the continuity of data acquisition, avoiding blind spots or repeated inspections caused by downtime for adjustment, and improving inspection efficiency and accuracy.

[0034] It should be added that the ultrasonic detection module integrated in the detector 909 is used for internal partial discharge and structural defect detection, while the appearance visual inspection module is used for surface damage and deformation detection. A single inspection can obtain multi-dimensional data of the transformer's internal and external parts without the need for multiple disassembly and replacement of inspection equipment, resulting in stronger data correlation.

[0035] In summary, when using this high-precision testing device for electrical engineering: First, the flip plate 905 is unfolded from the folding notches 803 of the two side wing plates 802. Then, the operator inserts the lifting rod 3 into the inlet 209 at the bottom of the cylindrical cam 208, and lifts the machine body 1 from the ground to the air by the end plate 5 of the lifting rod 3 until the electromagnet 203 at the top opening of the cylindrical cam 208 abuts against the bottom of the transformer housing. After that, the lifting rod 3 is rotated and the cross end 4 engages with the groove in the inlet 209 to make the eccentric profile at the top of the cylindrical cam 208 drive the insulating top rod 207 to rise. Then, after the electrical cap 206 at the top of the insulating top rod 207 contacts the receiving plate 204, a power supply 205 and electromagnet 203 are established and the electromagnet 203 is attracted and fixed to the bottom of the transformer housing. It should be noted that the entire process involves a closed-loop linkage of lifting to position, mechanical triggering, and electrical adsorption, eliminating the need for manual operation of the fixing device. This completely changes the traditional high-altitude inspection work scenario, achieving physical isolation between people and the hazardous environment. The core logic of existing technologies is that the equipment carries people plus manual operation, essentially expanding the range of human activity through a lift. The inspection process relies entirely on human skills. This application, however, constructs a new model of mechanical carrier plus automatic execution. Through a mechanical structure of lifting rod 3, fixing electromagnet 203, and multi-motor drive adjustment, the inspection tool is integrated onto the self-adjustable flip plate 905 and wing plate 802. There is no need for manual handling or contact with the detector 909. The electromagnet 203 automatically adsorbs and fixes the detector, replacing manual alignment. The lead screw and slider mechanism automatically adjusts the inspection parameters, enabling the machine to complete the core inspection action, fundamentally eliminating the dependence on manual operation.

[0036] Next, the rotary motor 6 is activated and drives the drive gear 7 to rotate. Under the meshing transmission between the outer circular teeth of the drive gear 7 and the driven gear ring 801, the driven gear ring 801 and its radially extending wing plates 802 on both sides are driven to swing back and forth outside the sleeve 201, so as to realize the angular offset of the detector 909 around the side of the transformer, covering the side peripheral area of ​​the cylindrical or polyhedral transformer. Then, when it is necessary to adjust the distance between the inner detector 909 of the flip plate 905 and the side of the transformer during use, the translation motor 804 is activated and the lead screw 805 is driven to rotate. Under the threaded engagement of the lead screw 805 and the slider 901, the slider 901 is driven to slide within the guide groove on the side wall of the wing plate 802, thereby realizing the dynamic adjustment of the distance between the inner detector 909 of the flip plate 905 and the side of the transformer, adapting to transformers of different diameters and surface irregularities, and avoiding data distortion caused by collisions or excessive distance during detection. Finally, when it is necessary to adjust the installation height of the detector 909 within the flip plate 905 during use, the lifting motor 906 is activated, driving the lead screw 907 to rotate. Under the threaded engagement of the lead screw 907 and the slider 908, the slider 908 is driven to slide within the guide groove on the inner wall of the flip plate 905, thereby adjusting the installation height of the detector 909 within the flip plate 905. This covers the vertical area of ​​the transformer from top to bottom, allowing for longitudinal inspection without the need for the entire moving equipment. This application achieves full-surface inspection coverage of the transformer without blind spots through three-dimensional dynamic adjustment of rotation offset angle, spacing, and height. The above parameters can be adjusted in real time during the inspection process without interrupting the inspection process, ensuring the continuity of data acquisition, avoiding blind spots or repeated inspections caused by downtime for adjustment, and improving inspection efficiency and accuracy.
