A novel adjustable reactor structure

Abstract

This utility model relates to the field of reactors, and more particularly to a novel adjustable reactor structure, comprising a reactor body, a gear ring, gears, and an iron core. The upper end of the reactor body has an upper retaining seat, and the lower end has a lower retaining seat. The top of the upper retaining seat has three through holes, into which the iron core is inserted. A gear ring arranged in a linear array is rotatably mounted on the top of the upper retaining seat, and gears are rotatably mounted between the gear rings. The outer wall of the iron core has threads, and the inner wall of the gear rings has threaded grooves, with the threads and grooves meshing. This device, through its design, allows for electrically controlled adjustment of the depth of the iron core inserted into the coil body, thereby adjusting the reactance amplitude. This solves the problem that existing reactors only have two modes—air core and solid core—lacking the ability to switch between them and provide stepless adjustment functionality.

Description

Technical Field

[0001] This utility model relates to the field of reactors, and in particular to a novel adjustable reactor structure. Background Technology

[0002] Reactors are inductive components used in power systems. They generate inductive reactance through coil windings, serving functions such as current limiting, filtering, and reactive power compensation. Their core principle is to use electromagnetic induction to impede changes in current. They are divided into two types: air-core (without an iron core, high linearity) and iron-core (with silicon steel sheets, high inductive reactance).

[0003] While existing technologies can achieve a certain reactive effect during use, they have drawbacks: existing reactors only have two modes, air-core and solid-core, lacking the ability to switch between the two and stepless adjustment. In view of this, we propose a new type of adjustable reactor structure that solves the above problems. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a novel adjustable reactor structure.

[0005] The technical solution of this utility model is as follows: A novel adjustable reactor structure includes a reactor body, a gear ring, gears, and an iron core. The upper end of the reactor body is provided with an upper retaining seat, and the lower end of the reactor body is provided with a lower retaining seat. The top of the upper retaining seat has three through holes, and the iron core is inserted into the through holes. A gear ring distributed in a linear array is rotatably mounted on the top of the upper retaining seat. Gears are rotatably mounted between the gear rings. The outer wall of the iron core is provided with threads, and the inner wall of the gear ring is provided with thread grooves. The threads and thread grooves mesh.

[0006] When in use, this device is no different from a common reactor. The connection method is the same: the main body is fixed to the upper end of the circuit, and then the contacts are electrically connected. This device mainly combines air core and solid core components. When it is necessary to increase the reactance, the motor drives the gear to rotate three gear rings simultaneously in the same direction, allowing the iron core to rotate into the coil inside the main body, increasing the reactance effect. When no increase is needed, the motor rotates in the opposite direction, and the iron core moves out of the coil center. Limiting rings are provided at the top and bottom of the iron core to prevent the iron core from separating due to excessive motor rotation. This device has the function of switching between strong and weak reactance, is simple to operate, can be integrated and controlled, and has high practicality.

[0007] Preferably, a mounting bracket is fixed to the surface of the upper bracket, and a motor is fixed to the upper end of the mounting bracket. The output shaft of the motor is fixedly connected to the rotation center of the upper end of the gear, and the lower end of the gear is rotatably connected to the upper bracket. The output shaft of the motor is directly connected to the gear to ensure that the gear ring rotates synchronously and to avoid the iron core from being misaligned or jammed. The motor is fixed to the mounting bracket, which saves space and makes it easy to integrate into the existing reactor system.

[0008] Preferably, the upper bracket is provided with upper bolts on both sides. The upper bolts fix the upper bracket laterally and lock the upper bracket laterally to prevent vibration or displacement during gear-ring transmission and ensure adjustment accuracy.

[0009] Preferably, the upper and lower card holders are connected to the main body via connecting columns. The connecting columns distribute the force on the upper and lower card holders, preventing the impact on the main body structure when the iron core moves, extending the service life, and facilitating fixed installation at corresponding points on the surface of the external structure.

[0010] Preferably, lower bolts are inserted into both sides of the lower bracket, and the lower bolts laterally fix the lower bracket, forming a bidirectional constraint with the upper bolts to ensure the stability of the overall structure under high voltage or high current.

[0011] Preferably, the lower bracket has positioning slots on both sides, and a rod is inserted into the lower end of the iron core. The rod is fixedly connected to the bottom of the body to prevent the iron core from rotating. The positioning slots cooperate with external supports or bases to simplify the on-site assembly process.

[0012] Preferably, the upper end of the upper card holder is fixed with buckles arranged in a square array, and the outer wall of one side of the main body is provided with a pair of contacts. The buckles support the quick installation of additional functional modules, improve system compatibility, and the paired contact design reduces contact resistance and avoids overheating.

[0013] Preferably, limit rings are fixed on both the upper and lower sides of the iron core.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] This invention utilizes a motor-driven gear ring to rotate, which engages with the iron core. The rotation of the gear ring is converted into the up-and-down movement of the iron core. The feed rate of the iron core can be infinitely adjusted by the motor, allowing the reactance to be adjusted to more subdivided levels, making it suitable for more complex circuits.

[0016] Based on the first beneficial effect, the gear rings are connected by a rotating gear. The participation of the gears can realize the synchronous and unidirectional rotation of the gear rings, and realize the simultaneous up and down movement of the three iron cores. This device has the function of finely dividing the reactance amplitude, which can be applied to more complex circuits and has high practicality.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The top of the upper retaining seat 12 has three through holes, and the iron core 5 is inserted into the through holes. The gear ring 8, which is linearly arrayed, is rotatably mounted on the top of the upper retaining seat 12. The gear 6 is rotatably mounted between the gear rings 8. The outer wall of the iron core 5 is provided with threaded wires, and the inner wall of the gear ring 8 is provided with threaded grooves. The threaded wires and threaded grooves mesh.

[0029] When in use, this device is no different from a common reactor, and the connection method is the same. The main body 1 is fixed at the upper end of the circuit, and then the contacts 9 are electrically connected. This device mainly combines air core and solid core into one unit. When it is necessary to strengthen the reactance, the motor 4 drives the gear 6 to drive the three gear rings 8 to rotate simultaneously in the same direction, so that the iron core 5 can rotate into the coil inside the main body 1 to increase the reactance effect. When it is not necessary to increase the reactance, the motor 4 rotates in the opposite direction, and the iron core 5 moves out of the center of the coil. The iron core 5 is equipped with limit rings 7 at the top and bottom to prevent the iron core 5 from separating due to excessive rotation of the motor 4. This device has the function of switching between strong and weak reactance, is simple to operate, can be integrated and controlled, and has high practicality. Example

The motor 4 is fixed to the mounting bracket 3, saving space and facilitating integration into the existing reactor system.

[0031] Upper bolts 13 are provided on both sides of the upper bracket 12. The upper bolts 13 fix the upper bracket 12 laterally and lock the upper bracket 12 laterally to prevent vibration or displacement during the transmission of gear 6-gear ring 8 and ensure adjustment accuracy.

[0032] The upper card holder 12 and the lower card holder 10 are connected to the main body 1 by a connecting post 11. The connecting post 11 distributes the force on the upper and lower card holders 10, avoids the impact on the structure of the main body 1 when the iron core 5 moves, extends the service life, and facilitates fixed installation on the corresponding points on the surface of the external structure.

[0033] Lower bolts 14 are inserted into both sides of the lower bracket 10. The lower bolts 14 fix the lower bracket 10 laterally and form a bidirectional constraint with the upper bolts 13 to ensure the stability of the overall structure under high voltage or high current.

[0034] The lower bracket 10 has positioning slots 15 on both sides. The lower end of the iron core 5 is inserted with a rod 16. The rod 16 is fixedly connected to the bottom of the body 1. The rod 16 prevents the iron core 5 from rotating. The positioning slots 15 cooperate with external brackets or bases to simplify the on-site assembly process.

[0035] The upper end of the upper card holder 12 is fixed with a square array of buckles 2. The outer wall of one side of the main body 1 is provided with a pair of contacts 9. The buckles 2 support the quick installation of additional functional modules, improve system compatibility, and the design of the pair of contacts 9 reduces contact resistance and avoids overheating.

[0036] Limiting rings 7 are fixed on the upper and lower sides of the iron core 5. The limiting rings 7 can prevent the iron core 5 from moving excessively and flying out of the through hole.
