Description

Technical Field

[0002] A transformer is an electrical device used to convert alternating current electrical energy between different voltage levels. It is widely used in power systems to improve the transmission efficiency and safety of electrical energy. Withstand voltage detection is an important test for transformers, aiming to ensure that the transformer can withstand a certain voltage without insulation breakdown or other failures under normal operating conditions.

[0003] When performing a withstand voltage test on a transformer, ensure that the transformer is in a power-off state. Then, connect the electrical clips and wires of the test component to the high-voltage winding of the transformer. Next, start the test equipment, gradually increase the voltage to the set value, and observe the readings of the test equipment to ensure that there is no breakdown or abnormal situation.

[0004] In the operation and use process of existing power equipment withstand voltage detection devices, it is necessary to manually wind the wire around the outer end of the high-voltage sleeve in sequence. This is not only time-consuming and laborious, but also due to manual operation differences, being too loose easily leads to poor contact, affecting signal transmission and reducing the accuracy of detection results. The clamping of the chuck also relies on manual labor, with low efficiency and safety risks. At the same time, it is difficult to accurately control the contact force and position, and it is extremely easy to cause detection data deviation due to poor contact. Summary of the Invention

[0020] According to an embodiment of the present invention in combination with Figure 1-8Shown.

The distance between the two eight-shaped plates 814 is smaller than the diameter of the high-voltage connection end, greatly improving the efficiency of the detection work, avoiding the errors and time consumption of manual handling and positioning, and enabling the transformer to accurately and quickly reach the detection position.

[0022] A dust removal component 82 is arranged inside the housing 87. The dust removal component 82 includes an airbag 821 arranged inside the housing 87, a spring 822 for returning position arranged inside the airbag 821.

Openings are arranged on the surface of the housing 87, and a number of openings are arranged. Automatically removing dust from the high-voltage connection end before detection can effectively remove dust and impurities on the surface, avoid interference of these foreign matters on the withstand voltage detection result, and improve the accuracy and reliability of the detection result.

[0023] The top pressing component 83 includes a side plate 831 arranged inside the housing 87. A rotating rod 833 is rotatably connected to one side of the side plate 831. One end of the rotating rod 833 is provided with a second hairspring 832, and the second hairspring 832 is connected to the side plate 831. An inclined plate 834 is arranged on the outer side of the rotating rod 833, which is convenient for driving.

[0024] The pressing component 84 includes a fixing plate 841 disposed inside the housing 87. One side of the fixing plate 841 is rotatably connected to a rotating shaft 842. A first gear 843 is disposed on the outer side of the rotating shaft 842. A first rack 844 is disposed on one side of the inclined plate 834.

A sleeve frame 849 is disposed on one side of the receiving plate 8410. A push plate 848 is slidably connected inside the sleeve frame 849. One end of the push plate 848 is provided with a hollow plate 847. The hollow plate 847 is slidably connected with the round block 846. One end of the push plate 848 away from the hollow plate 847 is provided with a fitting plate 8411. The fitting plate 8411 is used to fit the wire guiding ring 86 with the surface of the high-voltage connection end. A sleeve structure 85 is disposed on one side of the first rack 844. The sleeve structure 85 includes an adapter plate 851 disposed on one side of the first rack 844. The adapter plate 851 is inclined. One end of the adapter plate 851 is provided with a sleeve 852. The sleeve 852 is sleeved on the outer end of the wire guiding ring 86. Four groups of the sleeve structures 85 are equally spaced. The four groups of sleeves 852 drive the wire guiding ring 86 to move downward to be flush with the inner side of the fitting plate 8411, thus realizing that it is not necessary to manually wind the wire guiding ring 86 on the surfaces of the three high-voltage connection ends in sequence, saving time and effort and avoiding the cumbersome operation of manually winding the wire guiding ring 86.

[0025] The clamping structure 9 includes a side connection plate 91 disposed on one side of the connecting plate 10. A second rack 92 is disposed on one side of the side connection plate 91. A horizontal connection plate 93 is disposed on one side of the frame 5. A second gear 94 is rotatably connected to one side of the horizontal connection plate 93. A screw rod 95 is disposed on the outer side of the second gear 94. The second gear 94 is meshed and connected with the second rack 92. An extension plate 97 is disposed on one side of the horizontal connection plate 93. A long rod 98 is disposed on one side of the extension plate 97. A ring 99 is slidably connected to the outer side of the long rod 98. A sleeve 96 is disposed on one side of the ring 99. The sleeve 96 is threadedly connected with the screw rod 95. One end of the sleeve 96 is provided with a bottom connection plate 910. A chuck 911 is fixedly installed at the top end of the bottom connection plate 910. An electric push rod 912 is disposed on one side of the chuck 911. The electric push rod 912 is used to push one clamping handle of the chuck 911 to rotate, thereby clamping the surface of the high-voltage connection end. The clamping structure 9 realizes the automatic clamping connection between the detection component and the high-voltage connection end, avoids problems such as poor contact that may occur in manual clamping, and ensures the stability and reliability of the electrical connection.

[0026] A workpiece table 3 is disposed on one side of the conveyor belt 2. A clamping component 4 is disposed on one side of the workpiece table 3. The clamping component 4 is used to fix the transformer placed on the workpiece table 3. The detection component includes a withstand voltage detector disposed on one side of the frame 5. A cable is connected to one side of the withstand voltage detector. The cable is connected with the chuck 911.

[0027] Specifically, as Figure 1-4 shown, a feeding component and a discharging component are respectively arranged on both sides of the conveying table 1. A manipulator is used to convey the transformer to the corresponding workpiece table 3 on the surface of the conveyor belt 2, and the clamping component 4 is used to fix the transformer on the corresponding workpiece table 3. The clamping component 4 includes a bidirectional motor, a lead screw nut and a limiting component. The clamping component 4 can also fix the transformer on the surface of the workpiece table 3 in other ways, which is the prior art and will not be described in detail. With the start of the conveyor belt 2, the transformer is conveyed to the lower part of the frame 5. By arranging a moving guide rail 6 at the top of the frame 5, the driving moving guide rail 6 drives the cylinder 7 to move for position adjustment. Then, the cylinder 7 is started to drive the connecting plate 10 at the output end to move downward. Since the bottom end of the connecting plate 10 is correspondingly arranged with the three groups of high-voltage connection ends of the transformer, with the connecting plate 10 driving the three groups of automatic threading structures 8 to move downward, the outer shell 87 moves downward with the connecting plate 10, so that the high-voltage connection ends push open the two groups of eight-shaped plates 814. The two groups of eight-shaped plates 814 are rotated in the reverse direction by the rotating rods 813 to a longitudinal state, and the two rotating rods 813 respectively drive the clockwork spring 812 to rotate and store energy. The clockwork spring 812 facilitates the subsequent return of the eight-shaped plates 814. The two groups of eight-shaped plates 814 facilitate the alignment and positioning of the high-voltage connection ends. Only when the high-voltage connection ends simultaneously push open the two groups of eight-shaped plates 814 can the subsequent sleeving of the wire guide ring 86 be facilitated, greatly improving the efficiency of the detection work, avoiding the errors and time consumption of manual handling and positioning, enabling the transformer to accurately and quickly reach the detection position, and laying a good foundation for the subsequent withstand voltage detection; As Figure 5 shown, with the rotation and opening of the eight-shaped plates 814, the eight-shaped plates 814 squeeze the airbag 821, and the spring 822 inside the airbag 821 is squeezed and stores energy. Thus, the gas inside the airbag 821 is exhaled through the air outlet pipe 824 connected to the top end. Since one end of the air outlet pipe 824 is connected with an arc-shaped pipe, and a plurality of blowing heads 825 are equidistantly connected to the surface of the arc-shaped pipe, the gas inside the airbag 821 is exhaled through the blowing heads 825 in an arc-shaped trajectory to remove dust from the surface of the high-voltage connection ends. Automatically removing dust from the high-voltage connection ends before detection can effectively remove dust and impurities on the surface, avoid interference of these foreign matters on the withstand voltage detection results, and improve the accuracy and reliability of the detection results; As Figure 5As shown, the bottom end of the airbag 821 is connected to an air inlet pipe 823. One-way valves are provided on the surfaces of the air inlet pipe 823 and the air outlet pipe 824. When the airbag 821 is not squeezed and rebounds through the spring 822, the one-way valve on the surface of the air inlet pipe 823 is opened for air intake. When the airbag 821 is squeezed, the one-way valve on the surface of the air outlet pipe 824 is opened, and the gas inside the airbag 821 can only be exhaled through the air outlet pipe 824. The setting of the one-way valve ensures the orderly progress of the air intake and air outlet processes of the airbag 821, enabling the dust removal operation to be completed continuously and stably. At the same time, the rebounding effect of the spring 822 realizes the automatic reset and re-air intake of the airbag 821, prepares for the next dust removal, and improves the practicability and stability of the device; As Figure 3-7 shown, as the outer shell 87 continues to descend, the top end of the high-voltage connection end squeezes the four groups of inclined plates 834 inside the outer shell 87. The inclined plates 834 rotate from an inclined state to a horizontal state through the rotating rod 833. The rotating rod 833 drives the second hairspring 832 to rotate and store energy, facilitating the return of the inclined plates 834 when not squeezed through the rotational force of the second hairspring 832. The rotating rod 833 is fixed to the inner wall of the outer shell 87 through the side plate 831 connected by the rotating plate. As the four groups of inclined plates 834 rotate, they drive the first rack 844 on one side to move downward. Thus, the four groups of first racks 844 drive the collar 852 connected through the connecting plate 851 on one side to move downward. A wire guide ring 86 is sleeved inside the four groups of collars 852. Thus, the four groups of collars 852 drive the wire guide ring 86 to move downward to correspond to the inner side of the fitting plate 8411. As the first rack 844 moves downward, it meshes with the first gear 843. The first gear 843 drives the rotating shaft 842 at one end to rotate. One end of the rotating shaft 842 is rotatably connected to the fixing plate 841, and the fixing plate 841 is connected to the inner wall of the outer shell 87. The rotating shaft 842 drives the round block 846 on the surface of the rotating plate 845 to rotate one circle. The round block 846 slides from one end of the hollow plate 847 to the other end, causing the hollow plate 847 to drive the push plate 848 on one side to reciprocate once. The push plate 848 is slidably connected to the sleeve frame 849, and the sleeve frame 849 is connected to the inner wall of the outer shell 87 through the receiving plate 8410 on one side. Thus, the push plate 848 drives the fitting plate 8411 at one end to reciprocate, causing the fitting plate 8411 to squeeze the wire guide ring 86 to fit onto the surface of the high-voltage connection end, facilitating the withstand voltage detection of the high-voltage connection end. Thus, it is realized that there is no need to manually wind the wire guide ring 86 on the surfaces of the three high-voltage connection ends in sequence, saving time and effort. The entire automatic sleeving process of the wire guide ring 86 cleverly utilizes the linkage of the mechanical structure, avoiding the cumbersome operation of manually winding the wire guide ring 86. It not only improves the work efficiency but also ensures the consistency and stability of the fit between the wire guide ring 86 and the high-voltage connection end, providing a reliable connection for accurate withstand voltage detection; As Figure 8As shown, while the downward movement of the connecting plate 10 drives the rack two 92 fixed to the side connecting plate 91 to move downward. The rack two 92 is meshed and connected with the gear two 94. The rack two 92 drives the gear two 94 to rotate. The gear two 94 drives the screw rod 95 to rotate. One end of the gear two 94 is rotationally connected with a transverse connecting plate 93. The transverse connecting plate 93 is connected to the frame 5. The screw rod 95 is threadedly connected with the sleeve 96, so that the sleeve 96 drives the outer ring 99 to be slidably connected with the long rod 98. The long rod 98 is connected to the transverse connecting plate 93 through the extension plate 97. The sleeve 96 drives the bottom connecting plate 910 at one end to approach the corresponding high-voltage connection end. At the same time, the electric push rod 912 fixed to the clamping handle on one side of the chuck 911 is started. The start of the electric push rod 912 drives the other clamping handle at the output end to rotate and close to contact the surface of the high-voltage connection end, thus automatically completing the clamping work with the high-voltage connection end without manual operation. Then, only the voltage of the tester needs to be adjusted. The clamping structure 9 realizes the automatic clamping of the detection component and the high-voltage connection end, avoids problems such as poor contact that may occur in manual clamping, ensures the stability and reliability of the electrical connection, further improves the automation degree of the detection work and the accuracy of the detection result, and reduces the labor intensity of manual operation and human error.
