Description

Technical Field

[0001] This application relates to the field of circuit elements, and more particularly to a series reactor. Background Technology

[0002] Reactors, also called inductors, are widely used in circuits. Due to the electromagnetic induction effect, they possess inductance, which helps to resist changes in current. When a conductor carries current, it generates a magnetic field within the space it occupies; therefore, all current-carrying conductors have inductance in a general sense. However, the inductance of a long, straight conductor carrying current is relatively small, and the magnetic field it produces is not strong. Therefore, practical reactors are made by winding wire into a solenoid, called air-core reactors. Sometimes, to give the solenoid a larger inductance, an iron core is inserted into the solenoid, called an iron-core reactor.

[0003] Inside the compensation cabinet, when the three-phase lines are connected to the reactor and then connected in series from the reactor to the capacitor, the space inside the compensation cabinet is small and the wiring is relatively complex. In order to keep the wiring neat, cable ties are often needed to restrict the wiring of the reactor inside the compensation cabinet. However, after long-term use, the cable ties are prone to loosening, resulting in messy wiring inside the compensation cabinet and affecting the normal operation of the equipment. Therefore, this needs to be improved. Summary of the Invention

[0004] To address the issue of needing cable ties to restrict wiring when reactors are placed inside compensation cabinets in related technologies, this application provides a series reactor.

[0005] The series reactor provided in this application adopts the following technical solution:

[0006] A series reactor includes a coil, an upper mounting plate above the coil, a mounting groove on the upper mounting plate, a first mounting tube inserted into the mounting groove, a connecting groove on the inner side wall of the first mounting tube, an electrical plate coupled to the coil on the bottom wall of the connecting groove, a second mounting rod inserted into the first mounting tube, an electrical connector on the side wall of the second mounting rod, the electrical connector being inserted into the mounting groove and slidably connected to the mounting groove, the electrical connector abutting against the electrical plate, and a connector for connecting external wires at the end of the second mounting rod away from the first mounting tube.

[0007] By adopting the above technical solution, when the series reactor in this application is connected, when the three-phase line is connected to the reactor, the three-phase line is connected to the connector. Then, the second mounting rod is slid in the first mounting tube so that the distance of the second mounting rod extending out of the mounting plate changes. Therefore, when different three-phase lines are connected, the distance of the second mounting rod extending out of the mounting plate can be adjusted to distinguish the different three-phase lines, thereby making the wiring in the compensation cabinet more regular and reducing the possibility of line interference affecting the normal operation of the equipment.

[0008] Optionally, the outer wall of the mounting plate is provided with a fixing structure for fixing the second mounting rod.

[0009] By adopting the above technical solution, the fixed structure makes it difficult for the second mounting rod to slide horizontally after installation, thereby improving the stability of the second mounting rod during wiring and further improving the stability of the wiring inside the compensation cabinet.

[0010] Optionally, the fixing structure includes a locking rod, a locking plate, and a locking spring. A connecting plate is provided on the side wall of the second mounting rod, and a connecting hole is provided on the connecting plate. The locking rod is inserted into the connecting hole. A fixing hole is provided on the side wall of the mounting plate, and the locking rod is threadedly connected to the fixing hole. The locking plate is provided at the end of the locking rod away from the mounting plate. One end of the locking spring is connected to the mounting plate, and the other end abuts against the locking plate. The locking rod is inserted into the locking spring.

[0011] By adopting the above technical solution, the structure of the connecting piece and the locking rod allows the operator to rotate the locking rod to engage with the fixing hole, thereby changing the length of the locking rod extending out of the mounting plate. Since the connecting piece abuts against the locking rod, the position of the connecting piece changes under the action of the locking rod and the locking spring. Therefore, when the second mounting rod is adjusted to a suitable length, the second mounting rod is less likely to slip, thus improving the stability of the second mounting rod.

[0012] Optionally, the fixing structure includes a fixing ring, a connecting rod, a connecting block, and a limiting spring. The fixing ring is sleeved on the side wall of the second mounting rod and is interference-fitted with the second mounting rod. The connecting rod is disposed on the side wall of the fixing ring. A limiting groove is formed on the side wall of the mounting plate near the second mounting rod. The connecting block is slidably inserted into the limiting groove and is connected to the connecting rod. One end of the limiting spring is connected to the inner side wall of the limiting groove, and the other end is connected to the connecting block.

[0013] By adopting the above technical solution, when the second mounting rod is fixed using the structure of the fixed rubber ring and the connecting rod, the operator can pull the fixed rubber ring to fix it on the second mounting rod, and then push the limiting spring to limit the position of the connecting block, so that the position of the connecting block is restricted, and the connecting rod drives the fixed rubber ring to be fixed. The above structure improves the stability of the second mounting rod by fixing it with the limiting spring.

[0014] Optionally, the connecting block may be made of an insulating material.

[0015] By adopting the above technical solution, the connecting block is made of insulating material, which reduces the possibility of the operator's fingertips touching the connecting block due to its conductivity and thus improves the safety of the system.

[0016] Optionally, the connector includes a contact joint and a contact rod, the contact rod being rotatably connected to the second mounting rod, and the contact joint being located at the end of the contact rod away from the second mounting rod.

[0017] By adopting the above technical solution, through the structure of the contact rod and the second mounting rod being rotatably connected, the position of the contact joint can be adjusted not only by adjusting the length of the second mounting rod outside the mounting plate, but also by rotating the contact rod. This further improves the regularity of the wiring in the compensation cabinet and reduces the possibility of line interference affecting the normal operation of the equipment.

[0018] Optionally, a second locking groove is provided at the axial position of one end of the second mounting rod near the contact rod, and a axial connector is provided in the second locking groove. A second connecting groove is provided at the axial position of the contact rod, and a second connecting connector is inserted in the second connecting groove. The second connecting connector is connected to the contact connector.

[0019] By adopting the above method, and by setting a axial connector at the axis of the second mounting rod, when the second mounting rod and the contact rod rotate relative to each other, the second connecting connector abuts against the axial connector and the contact connector, so the circuit always remains connected, thereby making it relatively convenient to adjust the relative angle between the second mounting rod and the contact rod.

[0020] Optionally, the contact rod near the end of the second mounting rod has a plurality of first locking grooves, and the second mounting rod near the end of the contact rod has a first connecting groove. A fixed magnet is provided in the first locking groove, and a connecting magnet is provided in the connecting groove. The fixed magnet and the connecting magnet are magnetically attracted to each other. The first locking grooves are evenly opened along the end wall of the second mounting rod.

[0021] By adopting the above technical solution, and by using a structure in which a fixed magnet is inserted into the first locking groove and a connecting magnet is inserted into the first connecting groove, and by the attraction between the fixed magnet and the connecting magnet, the contact rod is less likely to rotate relative to the second mounting rod under the action of gravity, thereby improving the stability of the connection between the second mounting rod and the shaft connector.

[0022] Optionally, the contact rod includes a first connecting rod and a second connecting rod. The first connecting rod is rotatably connected to the second mounting rod. The second connecting rod is located at the end of the first connecting rod away from the second mounting rod. The contact connector is located at the end of the second connecting rod away from the first connecting rod. The second connecting rod and the first connecting rod are staggered.

[0023] By adopting the above technical solution, the second connecting rod is staggered with the first connecting rod, so that when the contact joint is making circuit connections, the radius of the circular trajectory of the second connecting rod when it rotates is larger, thereby increasing the wiring range and improving the overall applicability of the system.

[0024] Optionally, the second connecting rod is detachably connected to the first connecting rod.

[0025] By adopting the above technical solution, the second connecting rod is detachably connected to the first connecting rod. This allows the radius of the circular trajectory of the second connecting rod to be adjusted by replacing the second connecting rod. This enables the second connecting rod to be replaced according to actual conditions, such as the volume of the compensation cabinet, thereby improving the applicability of the system.

[0026] In summary, this application includes at least one of the following beneficial effects:

[0027] 1. The structure of electrical connectors and electrical plates is adopted. When the series reactor in this application is connected, when the three-phase line is connected to the reactor, the three-phase line is connected to the connector. Then, the second mounting rod is slid in the first mounting tube so that the distance of the second mounting rod extending out of the mounting plate changes. Therefore, when different three-phase lines are connected, the distance of the second mounting rod extending out of the mounting plate can be adjusted to distinguish different three-phase lines, thereby making the wiring in the compensation cabinet more regular and reducing the possibility of line interference affecting the normal operation of the equipment.

[0028] 2. The structure of the connecting plate and locking rod is adopted. The structure of the connecting plate and locking rod allows the operator to rotate the locking rod to engage with the fixing hole, thereby changing the length of the locking rod extending out of the mounting plate. Since the connecting plate and the locking rod abut against each other, the position of the connecting plate changes under the action of the locking rod and the locking spring. Therefore, when the second mounting rod is adjusted to the appropriate length, the second mounting rod is not easy to slip, thus improving the stability of the second mounting rod.

[0029] 3. A structure with a fixed rubber ring and connecting rod is adopted. When the fixed rubber ring and connecting rod are used to fix the second mounting rod, the operator can pull the fixed rubber ring to fix it on the second mounting rod, and then push the limit spring to limit the position of the connecting block, so that the position of the connecting block is restricted, and the connecting rod drives the fixed rubber ring to be fixed. The above structure improves the stability of the second mounting rod by fixing it with the limit spring. Attached Figure Description

[0036] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0037] This application discloses a series reactor.

[0038] Example 1: Refer to Figure 1A series reactor includes a coil 1, an iron core is disposed inside the coil 1, a mounting base plate 111 is disposed at the bottom of the coil 1, a mounting plate 11 is disposed at the top of the coil 1, and a wire electrically connected to the coil 1 is disposed inside the mounting plate 11.

[0039] Reference Figure 2 and Figure 3 The mounting plate 11 has a mounting groove 12 on its side wall. A first mounting tube 13 is welded and fixed inside the mounting groove 12. The first mounting tube 13 is entirely located inside the mounting groove 12, and an electrical plate groove 121 is formed on the inner side wall of the first mounting tube 13. An electrical plate 16 is glued and fixed to the inner bottom wall of the electrical plate groove 121. The electrical plate 16 is made of conductive material. A second mounting rod 14 is inserted into the first mounting tube 13. An electrical connector 17 is welded and fixed to the outer side wall of the second mounting rod 14. Both the second mounting rod 14 and the electrical connector 17 are made of conductive material, and the electrical connector 17 is inserted into the electrical plate groove 121, abutting against the electrical plate 16.

[0040] Reference Figure 2 and Figure 3 A fixing structure 2 for fixing the second mounting rod 14 is provided on the side wall of the mounting plate 11 near the second mounting rod 14. The fixing structure 2 includes a locking rod 21, a locking plate 22, and a locking spring 23. A connecting plate 24 is welded and fixed to the side wall of the second mounting rod 14. The connecting plate 24 has a connecting hole 25 extending through it along the length of the second mounting rod 14. The locking rod 21 is inserted into the connecting hole 25 and is a threaded rod. The locking plate 22 is welded and fixed to the end of the locking rod 21 away from the mounting plate 11, and the cross-sectional area of ​​the locking plate 22 is larger than the area of ​​the connecting hole 25. The locking plate 22 abuts against the connecting plate 24. A fixing hole 26 is provided on the side wall of the mounting plate 11 near the locking plate 22. The fixing hole 26 is a threaded hole, and the end of the locking hole near the mounting plate 11 is inserted into the fixing hole 26. The locking rod 21 is fitted with a locking spring 23. One end of the locking spring 23 near the mounting plate 11 is glued to the side wall of the mounting plate 11 near the connecting piece 24, and the other end abuts against the connecting piece 24.

[0041] Reference Figure 2 and Figure 3A connector 18 is provided at the end of the second mounting rod 14 away from the first mounting tube 13. The connector 18 includes a contact connector 4 and a contact rod 41. The contact rod 41 is located on the side of the contact connector 4 near the mounting plate. The contact rod 41 is connected to the second mounting rod 14. A second locking groove 54 is provided at the axis of the end of the second mounting rod 14 near the contact connector 4. An axis connector 55 is fixedly inserted in the second locking groove 54. A second connecting groove 57 is provided at the axis of the contact rod 41. A second connecting connector 56 is fixedly inserted in the second connecting groove 57 and is connected to the contact connector 4. Both the second connecting connector 56 and the contact connector 4 are conductive. The contact rod 41 has eight first locking grooves 5 at one end near the second mounting rod 14. A fixing magnet 51 is glued and fixed in the first locking groove 5, and the fixing magnet 51 is flush with the end wall of the contact rod 41. The second mounting rod 14 has a first connecting groove 52 corresponding to the first locking groove 5 at one end near the contact rod 41. A connecting magnet 53 is glued and fixed in the first connecting groove 52. The connecting magnet 53 is flush with the end wall of the second mounting rod 14, and the fixing magnet 51 and the connecting magnet 53 are magnetically attracted to each other.

[0042] Reference Figure 2 The contact rod 41 includes a first rod 61 and a second rod 62. The first rod 61 is rotatably connected to the second mounting rod 14. The second rod 62 is located at the end of the first rod 61 away from the second mounting rod 14, and the second rod 62 and the first rod 61 are detachably connected via a flange. The contact connector 4 is installed at the end of the second rod 62 away from the first rod 61. The second rod 62 has a Z-shaped structure, meaning that the end of the second rod 62 closest to the first rod 61 and the end of the second rod 62 connected to the contact connector 4 are not on the same vertical line. That is, the first rod 61 and the second rod 62 are staggered. The arrangement of the first rod 61 and the second rod 62 makes the radius of the circular trajectory of the second mounting rod 14 larger when it rotates, thereby increasing the wiring range and improving the overall applicability of the system.

[0043] The implementation principle of a series reactor in this application embodiment is as follows: When the series reactor in this application is in use, the operator can rotate the locking plate 22, causing the locking plate 22 to drive the locking rod 21 to rotate within the fixing hole 26, thereby adjusting the position of the locking plate 22 outside the mounting plate 11. Therefore, the length of the second mounting rod 14 outside the mounting plate 11 is adjusted. Then, the first connecting rod 61 and the second mounting rod 14 are rotated to adjust the position of the contact joint 4. When several contact joints 4 are adjusted to suitable connection positions, the reactor and capacitor are connected, thereby making the wiring in the compensation cabinet more regular in space and reducing the possibility of line interference affecting the normal operation of the equipment.

[0044] Example 2: Refer to Figure 4 and Figure 5 The difference between Embodiment 2 and Embodiment 1 is that the fixing structure 2 includes a fixing ring 3, a connecting rod 31, a connecting block 32, and a limiting spring 33. The fixing ring 3 is made of rubber and is sleeved on the second mounting rod 14. The fixing ring 3 and the second mounting rod 14 are interference-fitted, allowing the operator to manually adjust the position of the fixing ring 3. However, when the second mounting rod 14 slides, a large frictional force is generated between it and the fixing ring 3, thus limiting the second mounting rod 14. The connecting rod 31 is glued to the side wall of the fixing ring 3, and the end of the connecting rod 31 away from the fixing ring 3 is rotatably connected to the connecting block 32, which is made of rubber insulation material. A limiting groove 34 is provided on the side wall of the mounting plate 11 near the fixing collar. The connecting block 32 is inserted into the limiting groove 34 and is slidably connected to the limiting groove 34. A limiting spring 33 is glued to the inner side wall of the limiting groove 34. The limiting spring 33 is in a compressed state, and one end of the limiting spring 33 near the connecting block 32 is connected to the side wall of the connecting block 32.

[0045] When the second mounting rod 14 is fixed using the structure of the fixing ring 3 and the connecting rod 31, the operator can pull the fixing ring 3 to fix it onto the second mounting rod 14, and then push the limiting spring 33 to limit the position of the connecting block 32, thereby restricting the position of the connecting block 32 and causing the connecting rod 31 to drive the fixing ring 3 to be fixed. The above structure improves the stability of the second mounting rod 14 by fixing it with the limiting spring 33.

[0046] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
