Thus, a feature defined as "first", "second", and "third" may explicitly or implicitly include one or more of the features.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0028] In order to solve the technical problem of poor heat dissipation of inductive components in the prior art, the present application provides an integrated inductor.

[0029] See also Figure 1 and Figure 2 In a first aspect of the present application, an integrated reactor is provided. In a possible implementation, the integrated reactor includes: a base 6, a protective shell 9, a conjugate inductor 20, a capacitor 14, a resistor 10 and a water-cooling heat dissipation component; the conjugate inductor 20 includes: an iron core, a coil wound outside the iron core, and one or more copper bars connected to the coil outlet; the protective shell 9 is installed on the base 6, and the water-cooling heat dissipation component includes: a capacitor water-cooling radiator 13, a winding water-cooling radiator 12, an iron core water-cooling radiator 11 and a water-cooling bus 7, and the capacitor water-cooling radiator 13 is installed on the base 6. , the capacitor 14 is installed on the capacitor water-cooled radiator 13; the iron core water-cooled radiator 11 is arranged corresponding to the iron core, and the winding water-cooled radiator 12 is arranged corresponding to the winding; the capacitor water-cooled radiator 13, the winding water-cooled radiator 12 and the iron core water-cooled radiator 11 have a connected circulating water path, and the two ends of the water path are connected to the water inlet and the water outlet of the water-cooled bus 7; the capacitor 14 and the resistor 10 are divided into three groups, each group includes two capacitors 14 connected in series and one resistor 10, and after each group of capacitors 14 and resistors 10 are connected in series, one end is connected between each phase input and output of the conjugate inductor 20, and the other end is grounded.

[0030] In the above scheme, the design focus of the integrated inductor is on its compact structure and efficient heat dissipation. The base 6 not only provides structural support, but also serves as the installation basis for the main components. The design of the protective shell 9 takes into account the requirements of structural strength and easy assembly, and protects the internal components from external influences. The conjugate inductor 20 is the core component of the inductor, and its design optimizes the magnetic circuit structure and current distribution to improve the overall performance and efficiency. The material and shape of the core are carefully designed to achieve optimal magnetic permeability and minimum energy loss. The winding of the coil also takes into account the balance between the inductance and the resistance 10 value, as well as the control of temperature rise.

[0031] The use of copper busbars optimizes the transmission and distribution of current. Referring to FIG. 1 , specifically, the copper busbars include: upper outgoing line busbar I 101, upper outgoing line busbar II 103 and parallel starting busbar 105. The parallel starting busbar 105 is Figure 3 In the conjugate reactor input, the upper outgoing line row Ⅰ101 and the upper outgoing line row Ⅱ103 are the conjugate reactor output 1 and the conjugate reactor output 2.

[0032] The integrated reactor of the above scheme integrates capacitor 14, inductor, resistor 10 and water cooling technology by adopting a conjugate structure reactor, thereby improving the integration of the product; the reactor coil / winding is wound on the integral iron core, and the iron core is equipped with a water cooling radiator. The iron core structure is a conjugate structure, and the upper and lower winding structure, see Figure 1 and Figure 5 The yoke core 401 and the upper yoke core 402, the upper and lower windings share one incoming line row, the magnetic circuit of the reactor with a conjugated structure is more concentrated, the magnetic loss and eddy current loss are reduced, and the equipment efficiency is improved; the performance of the equipment can be further optimized by reasonably designing the parameters of the conjugated structure; the water-cooled heat dissipation structure is wound inside the winding, and the heat dissipation effect is improved under the condition of compactly arranging various components, taking into account the volume and performance of the product.

[0033] In the above solution, the core is made of high magnetic permeability material to further improve the performance and efficiency of the reactor.

[0034] See also Figure 7 In a possible implementation, the capacitor water-cooled radiator 13, the winding water-cooled radiator 12 and the iron core water-cooled radiator are installed in the middle position of the base 6, and the capacitor 14 and the conjugate inductor 20 are installed on both sides of the capacitor water-cooled radiator 13 and the iron core water-cooled radiator 11 respectively.

[0035] In the above scheme, the winding water-cooling radiator 12 and the iron core water-cooling radiator 11 are installed in the insulating material of the conjugate inductor (20), and are respectively arranged corresponding to the winding and the iron core to dissipate heat for the two.

[0036] The water-cooling heat dissipation components include: capacitor water-cooling radiator 13, winding water-cooling radiator 12 and core water-cooling radiator 11; the setting of each radiator ensures that the key components of the reactor can work in an environment with effective temperature control, extending the service life of the equipment and improving efficiency. The design of the water circuit allows cooling water to circulate between different radiators, thereby achieving efficient heat dispersion, effectively reducing the temperature of the equipment and extending the service life; in addition, the design of the water-cooling bus 7 takes into account the smoothness of water flow and easy maintenance.

[0037] The use of water cooling technology can effectively reduce the temperature of the equipment and extend its service life. The heat dissipation structure can adopt circulating water cooling or direct current water cooling. At the same time, in order to further improve the heat dissipation effect, a heat conducting sheet can be set in the heat dissipation structure or the heat dissipation area can be increased.

[0038] In the above scheme, the installation of the capacitor water-cooled radiator 13, the winding water-cooled radiator 12 and the core water-cooled radiator 11 is conducive to centralized cooling and improved heat dissipation efficiency. The design of installing the capacitor 14 and the conjugate inductor 20 on both sides makes the structure of the entire reactor more compact and convenient for maintenance and inspection. This layout also helps to minimize the electromagnetic interference inside the reactor; through the optimized design, the noise during the operation of the equipment is reduced.

[0039] See also Figure 6 In a possible implementation, it further includes: a control device 17 and a detection device 18, the detection device 18 and the control device 17 are respectively mounted on a mounting plate 21 on one side of the capacitor 14; one end of the control device 17 and the detection device 18 is connected between the three-phase input and output of the yoke inductor, and the other end is connected to each group of two capacitors 14 and resistors 10 connected in series. See the electrical connection diagram Figure 3 .

[0040] In the above scheme, the integrated reactor is increased with a control device 17 and a detection device 18, and the addition of these two devices improves the intelligent control and monitoring capabilities of the reactor. The control device 17 can adjust the working state of the reactor in real time based on the data provided by the detection device 18, thereby optimizing performance and reducing energy consumption. These devices are mounted on a mounting plate 21 on one side of the capacitor 14, which not only saves space, but also makes the circuit connection more concise. The control device 17 and the detection device 18 are directly connected to the three-phase input and output of the conjugate inductor 20, ensuring efficient signal transmission and processing.

[0041] The incoming line part is controlled by a contactor, and a signal is sent from a remote end to the control device 17 to realize remote control; the detection device 18 can be a current transformer connected to the incoming line end, which can detect the incoming line current.

[0042] In a possible implementation, it also includes: a terminal row 16, mounted on a mounting plate 21 on one side of the capacitor 14, the terminal row 16 includes one or more input ends and / or output ends of the following devices: one or more input ends and / or output ends of a conjugate inductor 20, a capacitor 14, and a resistor 10.

[0043] Further, in another embodiment, the introduction of the terminal block 16 provides a more flexible and convenient electrical connection option. The terminal block 16 makes it easier to connect the reactor to other electrical equipment or systems, simplifying installation and maintenance work. The design of the terminal block 16 takes into account easy access and high reliability connections.

[0044] In a possible implementation manner, the present invention further includes: a winding water-cooling radiator 12 is disposed inside the winding of the conjugate inductor 20 .

[0045] In the above solution, the winding water cooling radiator 12 is arranged inside the winding of the conjugate inductor 20. This design greatly improves the heat dissipation efficiency of the winding. Integrating the cooling system directly into the winding not only reduces the thermal resistance, but also improves the overall heat dissipation performance of the reactor. This is particularly important for reactors operating under high load or high temperature environment.

[0046] In a possible implementation manner, the capacitor 14 is mounted on the capacitor water-cooling radiator 13 by means of mounting bolts and a clamp 19 .

[0047] See also Figure 4 In the above scheme, the capacitor 14 is fixed to the capacitor water cooling radiator 13 by mounting bolts and clamps 19, see Figure 5 This installation method not only ensures the stability of the capacitor 14, but also facilitates maintenance and replacement. The use of the clamp 19 and the bolts provides sufficient mechanical strength to support the capacitor 14, while also allowing for quick disassembly when necessary.

[0048] The above scheme also includes: an integrated part 8, a capacitor 14 and a resistor 10 are integrated and installed together with a control 17 on a mounting plate 21 to form an integrated part 8, and the integrated part 8 is connected to the conjugate inductor (20) on the other side through a nut column 15 to form an integrated inductor as a whole, which has a compact structure and is convenient for installation, disassembly and maintenance.

[0049] In a possible implementation manner, a return opening 22 is provided at the bottom of the base 6 , and the return opening 22 accommodates a forklift fork.

[0050] In the above solution, a loop-shaped opening 22 is designed at the bottom of the base 6. This design takes into account the convenience of the reactor during transportation and handling. The loop-shaped opening 22 can accommodate forklift forks, thereby greatly reducing the difficulty of handling and installation. This design allows the reactor to be easily moved even in a narrow or inaccessible environment.

[0051] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0052] The above embodiments are only used to illustrate the technical solution of the present application rather than to limit it. Although the present application has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present application can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present application, which should be included in the scope of the technical solution requested for protection in the present application.
