[0002] A reactor is an inductive element that works based on the principle of electromagnetic induction. It is mainly used to limit current changes, stabilize voltage, suppress harmonics, or compensate reactive power.

[0003] Chinese Patent No. CN202223369610.8 discloses a reactor, including a magnetic yoke and a coil. The magnetic yoke is provided with a plurality of fasteners that pass through it laterally. A bracket connecting two adjacent fasteners is provided on one side of the magnetic yoke. At least one temperature controller terminal is installed on the bracket, and the temperature controller terminal is located between two adjacent fasteners.

[0004] As can be seen from the above, the design uses a bracket on the side of the magnetic yoke to mount the thermostat terminal, positioning the thermostat terminal between two fasteners. This helps prevent damage from external forces. However, the design also has the following shortcomings:

[0005] Firstly, the winding uses ordinary copper wire, which has low conductivity, resulting in a large voltage drop and high energy consumption during operation.

[0006] Secondly, the heat dissipation method is singular, relying mainly on natural heat dissipation, which can easily affect performance stability due to overheating when operating under high load;

[0007] Third, the fixing structure of the iron core and winding is not rigid enough, and it is easy to loosen due to vibration, and it is difficult to adapt to the installation requirements under different working conditions.

[0008] Therefore, a low-voltage-drop energy-saving filter reactor is proposed to address the above problems. Summary of the Invention

[0009] To overcome the shortcomings of existing technologies, such as large voltage drop, high energy consumption, and poor heat dissipation of reactors, this utility model proposes a low voltage drop energy-saving filter reactor.

[0010] The technical solution adopted by this utility model to solve its technical problem is as follows: The low voltage drop energy-saving filter reactor of this utility model includes a main body and an energy-saving component; the main body is composed of an upper iron core seat, a protective shell and a lower iron core seat, and the energy-saving component is set inside the protective shell, including a first clamping channel steel, a second clamping channel steel, a first clamping bolt, a water inlet, a second clamping bolt, a copper tube, a silicon steel sheet and a water outlet; the copper tube is spirally wound around the outside of the silicon steel sheet, the first clamping channel steel and the second clamping channel steel are symmetrically distributed on both sides of the silicon steel sheet, and the copper tube and the silicon steel sheet are clamped and fixed by the first clamping bolt and the second clamping bolt, and the water inlet and the water outlet are respectively sealed and connected to the two ends of the copper tube.

[0011] Preferably, the copper tube has 48 turns, the diameter of a single turn is adapted to the width of the silicon steel sheet, and the copper tube is made of high-conductivity copper.

[0012] Preferably, the water circulation passage formed by the inlet and outlet nozzles has a water circulation flow rate of 4 cubic meters per hour, the port diameter of the inlet and outlet nozzles is 20-30 mm, and the inner wall is provided with spiral guide patterns.

[0013] Preferably, the silicon steel sheets are made of high-efficiency, low-loss silicon steel material and are stacked in an alternating manner to form an iron core structure. The thickness of a single silicon steel sheet is 0.3-0.5mm, and the upper and lower ends of the silicon steel sheets are respectively fixedly connected to the upper iron core seat and the lower iron core seat by bolts.

[0014] Preferably, the protective shell is made of high-temperature resistant insulating material with a temperature resistance rating of not less than 120°C. The upper and lower ends of the protective shell are respectively sealed to the upper iron core seat and the lower iron core seat through sealing rings, and the side wall is provided with evenly distributed heat dissipation holes.

[0015] Preferably, the surfaces of the first and second clamping channel steels are galvanized for corrosion protection, and the channel steels have a U-shaped cross-section with an opening size that matches the thickness of the silicon steel sheet.

[0016] The advantages of this utility model are:

[0017] 1. This utility model achieves low-energy operation by combining a copper tube made of high-conductivity purple copper material with a high-efficiency, low-loss silicon steel sheet in an energy-saving component. The high conductivity of the purple copper tube reduces the winding resistance and thus reduces the voltage drop, while the low-loss silicon steel sheet reduces hysteresis and eddy current losses through optimized materials and stacking methods. This solves the problems of high energy consumption and large voltage drop caused by insufficient material performance in traditional reactors, and improves energy utilization efficiency.

[0018] 2. This utility model has a dual heat dissipation structure formed by the water circulation path consisting of the inlet and outlet nozzles and the heat dissipation holes of the protective shell. Combined with the U-shaped adaptation design of the first and second clamping channel steels and the galvanized anti-corrosion treatment, it can efficiently dissipate operating heat to adapt to high load conditions, and enhance structural stability and corrosion resistance. It solves the problems of poor heat dissipation, easy loosening of structure and weak environmental adaptability of traditional reactors, and improves the operating stability and service life of the equipment.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figures 1-2 As shown, a low voltage drop energy-saving filter reactor includes a main body 1 and an energy-saving component 2. The main body 1 consists of an upper iron core seat 11, a protective shell 12, and a lower iron core seat 13. The energy-saving component 2 is disposed inside the protective shell 12 and includes a first clamping channel steel 21, a second clamping channel steel 22, a first clamping bolt 23, a water inlet nozzle 24, a second clamping bolt 25, a copper tube 26, a silicon steel sheet 27, and a water outlet nozzle 28. The copper tube 26 is spirally wound around the outside of the silicon steel sheet 27. The first clamping channel steel 21 and the second clamping channel steel 22 are symmetrically distributed on both sides of the silicon steel sheet 27 and are clamped and fixed to the silicon steel sheet 27 by the first clamping bolt 23 and the second clamping bolt 25. The water inlet nozzle 24 and the water outlet nozzle 28 are respectively sealed and connected to both ends of the copper tube 26.

[0025] During operation, the energy-saving component 2, as the core functional component, is fixed inside the protective shell 12 by the upper iron core seat 11 and the lower iron core seat 13 to form a closed protective structure. The first clamping channel steel 21 and the second clamping channel steel 22 are bolted to tightly fit the copper tube 26 and the silicon steel sheet 27 to ensure magnetic field coupling efficiency. After the copper tube 26 is energized, it generates an alternating magnetic field, which works with the silicon steel sheet 27 to achieve the filtering function. At the same time, the water inlet nozzle 24 and the water outlet nozzle 28 are connected to the cooling system, and the operating heat is removed through liquid circulation.

[0026] Furthermore, the copper tube 26 has 48 turns, and the diameter of a single turn is compatible with the width of the silicon steel sheet 27. The copper tube 26 is made of high-conductivity copper.

[0027] During operation, the high conductivity of copper can significantly reduce winding resistance, and the 48 turns of the winding match the 27 width of the silicon steel sheet to ensure a uniform magnetic field distribution.

[0028] Furthermore, the water circulation passage formed by the inlet nozzle 24 and the outlet nozzle 28 has a water circulation flow rate of 4 cubic meters per hour. The port diameters of the inlet nozzle 24 and the outlet nozzle 28 are 20-30 mm, and the inner walls are provided with spiral guide patterns.

[0029] During operation, the spiral guide pattern causes the coolant to flow in a spiral pattern within the copper pipe 26, extending the heat exchange time. The flow rate of 4 cubic meters per hour ensures that heat is dissipated in a timely manner. The 20-30mm port diameter is compatible with conventional cooling pipes, improving system compatibility and avoiding performance degradation caused by local overheating.

[0030] Furthermore, the silicon steel sheet 27 is made of high-efficiency and low-loss silicon steel material, and is stacked in an interlaced manner to form an iron core structure. The thickness of a single silicon steel sheet is 0.3-0.5mm, and the upper and lower ends of the silicon steel sheet 27 are fixedly connected to the upper iron core seat 11 and the lower iron core seat 13 by bolts, respectively.

[0031] During operation, the low-loss silicon steel material and the 0.3-0.5mm thin sheet structure can significantly reduce eddy current and hysteresis losses; the staggered stacking method reduces magnetic resistance and improves magnetic permeability; the bolt connection with the core seat ensures the overall rigidity of the core and avoids structural loosening caused by vibration.

[0032] Furthermore, the protective shell 12 is made of high-temperature resistant insulating material with a temperature resistance rating of not less than 120℃. The upper and lower ends of the protective shell 12 are respectively sealed to the upper iron core seat 11 and the lower iron core seat 13 through sealing rings, and the side walls are provided with evenly distributed heat dissipation holes.

[0033] During operation, the high-temperature resistant material and sealing ring prevent external dust and moisture from entering, and the temperature resistance rating of over 120℃ adapts to high-load operating environments; the side wall heat dissipation holes work in conjunction with the internal water circulation to maintain the stable operating temperature of the components.

[0034] Furthermore, the surfaces of the first clamping channel steel 21 and the second clamping channel steel 22 are galvanized for corrosion protection. The channel steel has a U-shaped cross-section, and the opening size is adapted to the thickness of the silicon steel sheet 27.

[0035] During operation, the galvanized layer effectively resists environmental corrosion and extends service life; the U-shaped cross section is compatible with the thickness of the silicon steel sheet 27, ensuring uniform clamping of the copper tube 26.

[0036] Working Principle: During operation, current flows through the copper tube 26 made of red copper to generate an alternating magnetic field. The iron core formed by the silicon steel sheet 27 enhances the magnetic field strength. The filtering function is achieved using the principle of electromagnetic induction, removing harmonic components from the power grid. The high conductivity of the red copper tube 26 reduces winding resistance, and the high-efficiency, low-loss silicon steel sheet 27 reduces hysteresis and eddy current losses, thereby reducing voltage drop and overall energy consumption. Simultaneously, coolant is introduced through the water inlet 24, and guided by the spiral flow pattern inside the copper tube 26, it forms a spiral flow, increasing contact with the inner wall of the copper tube 26. Time, improve heat exchange efficiency, the coolant after absorbing heat is discharged from the water outlet 28, and the heat dissipation holes on the side wall of the protective shell 12 assist in heat dissipation, forming a dual heat dissipation system to adapt to high load operation; the first clamping channel steel 21 and the second clamping channel steel 22 clamp and fix the copper tube 26 and silicon steel sheet 27 through the first clamping bolt 23 and the second clamping bolt 25, combined with the bolt connection between the silicon steel sheet 27 and the upper iron core seat 11 and the lower iron core seat 13, to ensure the stability of the overall structure, effectively resist the influence of vibration, and adapt to the installation and operation requirements under different working conditions.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
