[0002] A magnetic flux trip device is a device that uses magnetic field changes to achieve mechanical tripping. It is commonly used in circuit breakers or switchgear to quickly cut off the circuit when abnormal current is detected. The intelligent measurement switch monitors the current in real time through the magnetic flux trip device, and combines sensors and microprocessors to achieve accurate current measurement and fault detection.

[0003] Currently, the existing magnetic flux trip devices for intelligent measurement switches have the following deficiencies in use: during actual operation of the existing magnetic flux trip devices for intelligent measurement switches, when the current borne by the electromagnetic trip device exceeds its rated value, it will cause the coil to overheat, which in turn will reduce the magnetization performance of the iron core and result in demagnetization. After the electromagnetic trip device is demagnetized, the magnetic force generated by it will weaken, leading to a reduction in the tripping speed. If not repaired in time, it may cause the electromagnetic trip device to malfunction during normal operation. In the case of faults such as short circuits, this may prolong the duration of the fault current, increase the risk of equipment damage, and thus affect the stability of system operation.

Detailed implementation manners

[0032] In an embodiment of the present invention, by providing a flux trip for an intelligent measurement switch, the following problems are solved: In the actual operation of the existing flux trip for an intelligent measurement switch, when the current borne by the electromagnetic trip exceeds its rated value, it will cause the coil to overheat, thereby reducing the magnetization performance of the iron core and resulting in a demagnetization phenomenon. After the electromagnetic trip is demagnetized, the magnetic force generated by it will weaken, resulting in a reduction in the tripping speed. If not repaired in time, it may cause the electromagnetic trip to malfunction during normal operation. In the case of faults such as short circuits, this may prolong the duration of the fault current and increase the risk of equipment damage, thus affecting the stability of system operation.

[0033] To better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0034] Combined with the appendix Figures 1-8A flux release for an intelligent measurement switch, comprising an intelligent measurement switch housing 1. A middle spacer 41 is fixedly connected to the inner side of the intelligent measurement switch housing 1. A wire passing plate 11 is fixedly installed on one side wall of the middle spacer 41. A magnetic push induction component 551 is arranged inside the intelligent measurement switch housing 1. The magnetic push induction component 551 includes two iron core tubes 7 arranged inside the intelligent measurement switch housing 1. A coil 8 is sleeved on the outer surface of the iron core tube 7. A moving core block 34 is arranged inside the iron core tube 7. A magnetic core sleeve 33 is inserted through one side of the iron core tube 7. A hook release push rod 42 is inserted and movably arranged inside the magnetic core sleeve 33. A clamping plate 2 is rotatably installed on one side of the intelligent measurement switch housing 1. Two internal insulation brackets 31 are fixedly connected to the upper surface of the clamping plate 2. A linkage conversion component 553 is rotatably installed on one side of the internal insulation bracket 31. A plurality of limiting slide rods 30 are fixedly connected to the inner side of the internal insulation bracket 31. A limiting slider 28 is inserted and slidably sleeved on the outer surfaces of the plurality of limiting slide rods 30 together. A positioning preparation component 555 is fixedly connected to one side of the limiting slider 28. A strengthening linkage rotating rod 20 is rotatably installed on the upper surface of the clamping plate 2. Pushing auxiliary components 552 are fixedly sleeved on both sides of the strengthening linkage rotating rod 20.

A positioning preparation component 555 is fixedly connected to one side of the limiting slider 28. The linkage conversion component 553 includes a threaded lead screw 29 rotatably installed on one side of the internal insulation bracket 31. A threaded sleeve block 27 is threadedly sleeved on the outer surface of the threaded lead screw 29. A worm 26 is fixedly connected to the bottom end of the threaded lead screw 29. The worm 26 is rotatably arranged with the clamping plate 2. The limiting slider 28 is fixedly connected to the threaded sleeve block 27. A driving traction component 554 is fixedly installed on the inner wall of the intelligent measurement switch housing 1. The driving traction component 554 includes a micro driver 6 fixedly installed on the inner wall of the intelligent measurement switch housing 1. A first pulley 23 is fixedly sleeved on the output shaft of the micro driver 6. A second pulley 24 and a worm gear 25 are respectively fixedly sleeved on one end of the internal insulation bracket 31. The first pulley 23 is connected to the second pulley 24 through a belt. The worm gear 25 is engaged with the worm 26. A contact overload channel 4 is arranged inside the intelligent measurement switch housing 1. A current conducting sheet 16 is arranged inside the intelligent measurement switch housing 1. An anti-interference block 3 is arranged inside the intelligent measurement switch housing 1.

[0035] After the above technical solution operates through the micro driver 6, the output shaft drives the first pulley 23 to rotate, thereby driving the second pulley 24 to rotate synchronously through the belt. When the second pulley 24 rotates, it can drive the worm wheel 25 to rotate accordingly, causing the engaged worm 26 to rotate. After the worm 26 rotates, it drives the connected threaded lead screw 29 to rotate, thus enabling the threaded sleeve block 27 to move upward. Under the movement of the threaded sleeve block 27, the limiting slider 28 is driven to move synchronously. After the limiting slider 28 moves, it stably slides on the limiting slide bar 30, further driving the short connecting rod 35 to move, thereby driving the chamber draft seat 45 to move and lift the unhooking push rod 42, causing the lower iron core tube 7 to move upward. This is beneficial for timely replacing components such as the iron core after a short circuit fault, avoiding damage to the equipment, and further improving the maintenance efficiency and safety quality of the overall flux release.

[0036] For a further technical solution, the pushing auxiliary component 552 includes adapter plates 32 fixedly sleeved on both sides of the reinforced linkage rotating rod 20. A guiding groove 37 is formed in the middle of the adapter plate 32. A guiding slide frame 38 is inserted and slidably arranged inside the guiding groove 37. Two matching snap rings 43 and placement ring pieces 44 are respectively rotatably connected inside the guiding slide frame 38. Both sides of the reinforced linkage rotating rod 20 are fixedly connected with reverse couplings 36. A traction turntable 21 is sleeved on one side of the reverse coupling 36. A boosting push rod 22 is fixedly connected to the corresponding side of the two traction turntables 21. Two path connectors 12 connected to the wire passing pieces 11 are fixedly connected to one side of the intermediate spacer 41. The circuit connector 40 is snap-connected to the path connector 12. The positioning preparation component 555 includes a plurality of short connecting rods 35 fixedly connected to one side of the limiting slider 28. A chamber draft seat 45 is fixedly connected to the corresponding side of the plurality of short connecting rods 35. A guiding bridge frame 18 is fixedly connected to the upper surface of the clamping plate 2. An arc-shaped limiting frame 17 is fixedly connected to one side of the guiding bridge frame 18.

[0037] In response to the above technical solution, driven by the output shaft of the micro drive 6, the traction turntable 21 starts to rotate counterclockwise, and drives the reinforced linkage rod 20 to rotate in the reverse direction through the reverse coupling 36, thereby driving the adapter plate 32 to turn upward. When the adapter plate 32 turns, it can drive the snap ring 43 and the placement ring piece 44 to move, so as to drive the upper hook release push rod 42 to move, so that the hook release push rod 42 slides between the arc-shaped limiting frame 17 and the guiding bridge 18. During this process, the guiding slide 38 will be driven to slide in the guiding groove 37. When the iron core tube 7 is driven to the bend of the guiding bridge 18, it stops. At this time, the rotation of the traction turntable 21 drives the assist push rod 22 to a predetermined angle to push down the hook release push rod 42. When personnel need to repair, open the clamping plate 2 and take it out. Then, as the limiting slider 28 drives the short connecting rod 35 to move, and pushes the chamber draft seat 45 to lift the hook release push rod 42, so as to drive the side communication core plate 14 to move upward and enter the outside of the wire passing piece 11 to engage with it. At the same time, the iron core tube 7 drives the coil 8 to move, so that the circuit connector 40 moves to a predetermined position and engages with the passage chuck 12. After replacement, the push assist component 552 is reset. During this process, the snap ring 43 abuts and lifts against the chamber draft seat 45, and the placement ring piece 44 pushes the hook release push rod 42 to slide in the chamber draft seat 45, so as to shovel the hook release push rod 42 into the placement ring piece 44. After that, the linkage conversion component 553 is reset and waiting for personnel to maintain and replace the spare parts again, so as to replace the new magnetic flux components in time when the load of the magnetic flux tripping coil part of the measuring switch or the magnetic force is insufficient due to short circuit, ensure the normal operation of the switch, and reduce the maintenance time.

[0038] A further technical solution is that a telescopic device 9 is fixedly installed on the inner wall of the intelligent measurement switch housing 1, and a phase change material cylinder 10 is arranged on one side of the telescopic device 9.

[0039] In response to the above technical solution, when the magnetic flux tripping device is in use, the telescopic device 9 can be opened to push the phase change material cylinder 10 to move. After the phase change material cylinder 10 moves, it gradually approaches the iron core tube 7 and is inserted into the other end of the hook release push rod 42. Thus, during use, the component can absorb or release heat in the face of temperature changes, so as to achieve the effect of cooling when heated and warming when cooled. This is beneficial for the magnetic flux tripping device to effectively prevent the coil from losing magnetism due to overheating during long-term use and ensure the tripping speed.

[0040] The specific usage method of the present invention:

[0041] In a magnetic flux release for an intelligent measuring switch of the present invention, the switch of the micro-driver 6 is first turned on by an external controller. After the micro-driver 6 is running, the output shaft drives the first pulley 23 to rotate, thereby driving the second pulley 24 to rotate synchronously through the belt. When the second pulley 24 rotates, it can drive the worm wheel 25 to follow the rotation, so that the meshing worm 26 is driven to rotate. After the worm 26 rotates, it drives the connected threaded screw 29 to rotate, so that the threaded sleeve 27 moves upward, and the movement of the threaded sleeve 27 drives the limiting slider 28 to move synchronously. After the limiting slider 28 moves, it slides stably on the limit slide 30, and further drives the short connecting rod 35 to move, so The driving chamber drawing seat 45 moves to lift the unhooking push rod 42, so that the lower iron core tube 7 moves upward, and at the same time, the traction turntable 21 starts to rotate counterclockwise under the drive of the output shaft of the micro-driver 6, and drives the reinforced linkage rotating rod 20 to rotate in the opposite direction through the reverse coupling 36, thereby driving the adapter plate 32 to flip upward. When the adapter plate 32 flips, it can drive the clamping ring 43 and the placement ring piece 44 to move, so that the upper unhooking push rod 42 moves, so that the unhooking push rod 42 slides between the arc-shaped limit frame 17 and the guide bridge frame 18, and in the process, it drives the guide slide 38 to slide in the guide groove 37. When the iron core tube 7 is driven to the bend of the guide bridge frame 18, When the traction turntable 21 rotates, it drives the assist push rod 22 to a predetermined angle to push the unhooking push rod 42 down. When the personnel need to repair, the clamping plate 2 is opened and taken out. Then, the limiting slider 28 drives the short connecting rod 35 to move, and pushes the chamber drafting seat 45 to lift the unhooking push rod 42, so that the driving side connecting core plate 14 moves upward and enters the outer side of the through-line piece 11 to engage with it. At the same time, the iron core tube 7 drives the coil 8 to move, so that the circuit connector 40 moves to a predetermined position and engages with the passage clamp 12. After replacement, the auxiliary component 552 is pushed to reset. During the process, the clamping ring 43 contacts and lifts up the chamber drafting seat 45, and the ring piece 44 is placed to push the unhooking push rod 42 on the chamber drafting seat 45, thereby shoveling the unhooking push rod 42 into the placement ring piece 44, and then the linkage conversion component 553 is reset and the spare parts can be replaced by personnel for maintenance. Therefore, when the magnetic flux release coil of the measuring switch is partially loaded or the short-circuit magnetism is insufficient, a new magnetic flux component can be replaced in time to ensure the normal operation of the switch and reduce maintenance time. When the magnetic flux release is in use, the phase change material cylinder 10 can be pushed to move by opening the telescopic device 9. After the movement, the phase change material cylinder 10 gradually approaches the iron core tube 7 and is plugged with the other end of the unhooking push rod 42. Therefore, in use, the component can absorb or release heat when facing temperature changes, thereby achieving the effect of cooling when hot and heating when cold.
