Description

Technical Field

[0001] This invention relates to the field of high-voltage fuse technology, specifically to a high-voltage fuse debugging and testing device. Background Technology

[0002] High-voltage fuses are critical protective components in power systems, primarily used for overload and short-circuit protection. Their performance directly affects the safe and stable operation of the power system. In a power system, when the current abnormally rises above the rated carrying capacity of equipment or lines, it may cause equipment damage, fire, or even more serious safety accidents. High-voltage fuses, through their internal fuse wires or contacts, quickly melt and break the circuit when the current exceeds a set value, effectively preventing these hazards. Drop-out fuses are a commonly used short-circuit protection switch, characterized by their economy, practicality, ease of operation, and strong adaptability. To ensure smooth use of drop-out fuses after production, they undergo commissioning and testing before leaving the factory. This includes testing the current conductivity, resistance value, and mechanical structural stability of the fuses. However, manual disassembly and reassembly of the fuse and switching between testing scenarios during commissioning affect the convenience and efficiency of the process. Furthermore, existing testing equipment is not suitable for commissioning and testing fuses of different specifications. Therefore, we propose a high-voltage fuse commissioning and testing device.

The second electric telescopic rod 39 and the second brake motor 45 are controlled by the control panel 65 on the front of the pentagonal box 1. This is a conventional technology. The output ends of the two second electric telescopic rods 39 are fixedly connected to the moving columns 40.

The lifting seats 38 are provided with holes for the first detection lines 43 to pass through, and the first detection lines 43 can be set as elastic coils so that they can be extended and retracted.

[0021] The mechanical strength testing unit 7 includes a third sealing plate 47 hinged to the inner cavity of the third testing port 46. The third sealing plate 47, the second sealing plate 34, and the first sealing plate 23 are all equipped with locking devices to secure them.

The outer diameter of the plug post 57 is smaller than the inner diameter of the through hole 61. At the same time, when the upper support seat 18 and the lower support seat 15 move to the lower and upper parts of the two plug posts 57, the plug post 57 is aligned with the through hole 61 so that the plug post 57 can pass through the through hole 61 so that the second detection post 60 contacts the top and bottom of the insulating post of the fuse.

[0025] In summary, when using this high-voltage fuse debugging and testing equipment, firstly, place the bottom of the insulating post on the standard drop-out fuse into the slot 21 on the lower support 15 through the pick-and-place port 3. Then, start the first brake motor 14 to drive the first bidirectional screw 11 to rotate. Through the threaded engagement between the first bidirectional screw 11 and the two pentagonal plates 12, the two pentagonal plates 12 are moved closer together. The lower pentagonal plate 12 drives the lower support 15 and the fuse to move upward, simultaneously causing the top of the insulating post on the fuse to insert into the slot 21 at the bottom of the upper support 18. At this time, turn off the first brake motor 14 and start the third brake motor 62 to drive the first spur gear 64 to rotate intermittently one revolution. Through the meshing transmission between the first spur gear 64 and the second spur gear 63, the pentagonal box 9 is driven. The lower support 15, upper support 18, and standard fuse rotate intermittently. When the standard fuse moves to face the detection plate 31, the first electric telescopic rod 25 is activated, driving the moving plate 26, telescopic cylinder 28, telescopic square column 30, and detection plate 31 to move closer to the fuse, so that the outer side of the fuse tube on the fuse contacts the first contact sensor 32 on the detection plate 31. When the standard fuse moves to face the second mounting box 35, the second brake motor 45 is activated, driving the second bidirectional screw 36 to rotate. Through the threaded engagement between the second bidirectional screw 36 and the two lifting seats 38, the two lifting seats 38 are moved, so that the positions of the two first detection columns 44 are aligned with the upper and lower terminals on the standard fuse. Then, when the standard fuse re-enters the airflow... When the fuse is moved to face the pick-up / drop-off port 3, remove the standard fuse from the lower support 15 and the upper support 18. Then, insert the top of the manufactured fuse insulation post into the slot 21 below the upper support 18 and push the upper support 18 upwards. At this point, the first spring 17 is stretched. When the bottom of the fuse insulation post moves to the top surface of the lower support 15, release the push on the upper support 18, allowing the bottom of the fuse insulation post to insert into the slot 21 on the lower support 15. Simultaneously, the restoring force of the first spring 17 drives the upper support 18 downwards, allowing the fuse to be installed on the lower support 15 and the upper support 18. Then, use the pentagonal box 9 to intermittently rotate the fuse to be tested by a certain angle. When the fuse moves to face the test plate 31 and the fuse tube is aligned with the first... When the first contact sensor 32 makes contact, if the pressure sensor 27 is not compressed, it indicates that the position between the insulating post and the fuse tube on the fuse is acceptable. If the pressure sensor 27 is squeezed by the telescopic cylinder 28, the second spring 29, the telescopic square post 30, and the detection plate 31, it indicates that the fuse tube on the fuse is squeezing the first contact sensor 32 on the detection plate 31, indicating that the position between the insulating post and the fuse tube on the fuse is unacceptable. When the fuse is detected as unacceptable, the fuse is removed from the lower support base 15 and the upper support base 18 through the discharge port 5 and reassembled. When the fuse is acceptable, the fuse continues to rotate so that it is aligned with the first detection post 44. At this time, the two second electric telescopic rods 39 are activated to move the two first detection posts 44 toward the fuse.The ends of the two first detection posts 44 are brought into contact with the upper and lower terminals on the fuse. The DC resistance of the fuse is measured using a high-precision micro-ohmmeter 42, the first detection line 43, and the first detection posts 44 to determine whether the internal connection is good and whether the contact resistance is within the allowable range. When the fuse continues to rotate due to the pentagonal box 9, so that the fuse is facing the tension sensor 50, the end of the hook 51 is located between the insulating post and the fuse tube on the fuse. The third electric telescopic rod 49 drives the tension sensor 50 and the hook 51 to move outward, and the hook 51 pulls the fuse tube on the fuse. The tension sensor 50 measures the tension of the hook 51 and detects the static tension of the hook 51 pulling the fuse tube away from the fuse to assess the stability of its mechanical structure. At this time, the two fourth electric telescopic rods 54 are activated to drive the two lifting blocks 56 and the two... The two insertion posts 57 are brought close together so that they are inserted into the through holes 61 on the lower support base 15 and the upper support base 18. When the second contact sensor 58 at the end of the insertion post 57 contacts the top and bottom of the insulating post of the fuse, the two second detection posts 60 contact the top and bottom of the insulating post respectively. The resistance value to the insulating post is measured using an electronic megohmmeter 53, the second detection line 59, and the second detection posts 60 to ensure electrical isolation performance. Finally, when the tested fuse is moved back to face the pick-up and drop-off port 3, the fuse is pushed upward to move the upper support base 18 upward so that the tested fuse can be removed. Other fuses to be tested are then installed on the lower support base 15 and the upper support base 18 for further testing. In addition, multiple sets of lower support bases 15 and upper support bases 18 on the side of the pentagonal box 9 can be used to install different fuses to be tested, so that multiple fuses can be tested simultaneously.

[0026] The control method of the present invention is through the control panel 65. The control circuit of the control panel 65 can be implemented by those skilled in the art through simple programming. The data measured by the electronic megohmmeter 53 and the high-precision micro-ohmmeter 42 can also be transmitted to the control panel 65 so that all the detection data can be viewed from the control panel 65. The power supply is common knowledge in the art, so the control method and circuit connection will not be explained in detail in the present invention.

[0027] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
