Description

Technical Field

[0001] This utility model belongs to the technical field of air-core reactors, specifically an air-core reactor. Background Technology

[0002] A reactor is an electrical device used to limit or regulate current in a circuit. It mainly uses inductive characteristics to suppress current surges or harmonics and is widely used in power systems, industrial equipment, and electronic circuits. Its core function is to provide inductive reactance, thereby limiting short-circuit current, compensating for reactive power, or filtering high-frequency interference.

[0003] Some reactors are produced using a multi-curing process. The high temperature during each curing process repeatedly affects the insulation material, which can easily lead to aging, embrittlement, or performance degradation of the insulation material, damaging the integrity of the insulation structure. In addition, the inner liner and the reactor body are often designed separately, which can easily create gaps during assembly, forming weak points in the insulation. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a hollow reactor, which solves the problem that reactors often adopt a multi-curing production mode, which easily leads to aging, embrittlement or performance degradation of the insulation material, damaging the integrity of the insulation structure. In addition, the inner liner and the reactor body are mostly designed separately, which can easily create gaps during assembly, forming weak points in the insulation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hollow reactor, comprising a binding strap, an upper busbar, a product body, a lower busbar, and inlet / outlet terminals. An inlet terminal is provided on one side of the upper busbar. The upper and lower busbars are respectively located above and below the product body. An mounting screw is threaded onto the lower busbar, and an outlet terminal is provided on one side of the lower busbar. A post insulator is installed below the lower busbar via the threaded engagement of the mounting screw. An inner liner is connected inside the product body. Binding grooves are provided on both sides of the upper and lower busbars. Mounting holes are provided on both the upper and lower busbars. Full-threaded screw rods are threaded into the mounting holes, and fastening nuts are threaded onto both ends of the full-threaded screw rods. Wire welding positions are provided on both the upper and lower busbars.

[0006] As a further embodiment of this utility model: the incoming terminal on the upper busbar side and the outgoing terminal on the lower busbar side together constitute the incoming and outgoing terminal part; the inner liner and the product body are rigidly integrated and insulated, and the substrate is treated and encapsulated by wet winding of glass fiber non-woven tape.

[0007] As a further embodiment of this utility model: the upper busbar and the lower busbar are flat and horizontally placed along the long side of the cross section, and the inlet terminal and the outlet terminal are respectively located on both sides of the product body and are symmetrically distributed vertically and centrally.

[0008] As a further embodiment of this utility model: the binding strap is bound in the binding groove of the upper busbar and the lower busbar, and the binding strap is tightened once in the inclined direction and once in the straight direction through the binding groove.

[0009] Compared with existing technologies, the advantages of this utility model are as follows: By performing overall curing after the wire welding is completed and fully assembled, the entire unit is cured in one go, which avoids the damage to the insulation material caused by multiple high-temperature curing processes, reduces the number of processes, and lowers production time and power consumption costs. The flat upper and lower busbar design significantly increases the support area for the coil, thereby improving support stability and facilitating the connection between the product body and the post insulator. Furthermore, the flat placement reduces the volume of the product body and the number of upper and lower busbars required. At the same time, the integrated structure of the inner liner and the product body eliminates the cost of multiple mold types and the product damage caused by disassembly, saving process flow and operation time. In addition, the high strength of the inner liner and its rigid connection with the coil can avoid deformation caused by thermal expansion and contraction during furnace curing, ensuring the accuracy of the product shape and parameters. Moreover, the fiberglass non-woven tape encapsulation process makes processing more convenient, giving this hollow reactor the advantages of small size, stable production parameters, low production cost, no need for additional tooling, and easy processing.

[0011] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0012] like Figure 1-9 As shown, this utility model provides a technical solution: a hollow reactor, including a binding strap 2, an upper busbar 3, a product body 4, a lower busbar 5, and an inlet / outlet terminal section 10. An inlet terminal 1 is provided on one side of the upper busbar 3. The upper busbar 3 and the lower busbar 5 are respectively located above and below the product body 4. An installation screw 6 is threaded onto the lower busbar 5. An outlet terminal 7 is provided on one side of the lower busbar 5. The inlet terminal 1 on one side of the upper busbar 3 and the outlet terminal 7 on one side of the lower busbar 5 together constitute the inlet / outlet terminal section 10. The inner liner 9 and the product body 4 are rigidly integrated and insulated, and the substrate is treated and encapsulated by a glass fiber non-woven wet winding method. By adopting a rigid integrated insulation design between the inner liner 9 and the product body 4, the weak insulation area formed by the assembly gap between the two is eliminated structurally.

[0013] A support insulator 8 is installed below the lower busbar 5 via a screw 6. An inner liner 9 is connected inside the product body 4. Binding grooves 11 are provided on both sides of the upper busbar 3 and the lower busbar 5. Binding straps 2 are bound in the binding grooves 11 of the upper busbar 3 and the lower busbar 5. The binding straps 2 are tightened once in the inclined direction and once in the straight direction through the binding grooves 11. By binding the binding straps 2 together in the binding grooves 11 of the upper busbar 3 and the lower busbar 5, the upper busbar 3 and the lower busbar 5 are fixed above and below the product body 4, respectively. The double binding in the inclined direction and the straight direction can form a cross-force structure between the upper busbar 3, the lower busbar 5 and the product body 4. Compared with binding in a single direction, it can improve the balance of force on the upper busbar 3 and the lower busbar 5, so that the upper busbar 3 and the lower busbar 5 can maintain a precise docking position with the coil.

[0014] Both the upper busbar 3 and the lower busbar 5 have mounting holes 12. A full-threaded screw rod 14 is threaded into the mounting hole 12, and a fastening nut 13 is threaded onto both ends of the full-threaded screw rod 14. During assembly, the upper busbar 3 and lower busbar 5 are positioned above and below the product body 4 respectively using the full-threaded screw rod 14 and the fastening nut 13. The upper busbar 3 and lower busbar 5 are then secured by binding. Afterwards, the full-threaded screw rod 14 is removed by loosening the fastening nut 13, thus completing the installation and positioning operation of the upper busbar 3 and lower busbar 5. Both the upper busbar 3 and lower busbar 5 are provided with wire soldering positions 15. The upper busbar 3... The upper busbar 3 and lower busbar 5 are flat and horizontally placed along the long side of the cross-section. The input terminal 1 and output terminal 7 are symmetrically distributed on both sides of the product body 4. By placing the flat upper busbar 3 and lower busbar 5 horizontally along the long side of the cross-section, the conductive cross-sectional area of ​​the upper busbar 3 and lower busbar 5 can be greatly increased within the same installation space, reducing the resistance during current transmission. The input terminal 1 and output terminal 7 are symmetrically distributed on both sides of the product body 4. This layout makes the path of current flowing in from the input terminal 1, through the coil, and out to the output terminal 7 more regular, forming a uniform current loop.

[0015] The working principle of this utility model is as follows: During the production process, after the wire welding is completed and the assembly is finished, the entire assembly is then cured. This one-time curing structure design avoids the damage to the insulation material caused by multiple high-temperature curing processes, reduces the number of processes, and lowers production time and power consumption costs. The flat upper busbar 3 and lower busbar 5 design significantly increases the support area for the coil, thereby improving support stability and facilitating the connection between the product body 4 and the post insulator 8. The flat placement also reduces the volume of the product body 4 and the number of upper and lower busbars 3 and 5 required. At the same time, the integrated structure of the inner liner 9 and the product body 4 eliminates the cost of multiple mold types and the product damage caused by disassembly, saving process time and operation time. In addition, the high strength of the inner liner 9 and its rigid connection with the coil can prevent deformation caused by thermal expansion and contraction during furnace curing, ensuring the accuracy of the product's shape and parameters. Furthermore, the fiberglass non-woven tape encapsulation process makes processing more convenient, giving this hollow reactor the advantages of small size, stable production parameters, low production cost, no need for additional tooling, and easy processing.
