It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of the present utility model.
[0029] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and do not necessarily have to be used to describe a specific order or sequence.
[0030] The terms "comprising" and "having" in the specification and claims of the present application and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device comprising a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.
[0031] An inductance control system 1, as Figures 1-8 shown, includes: an inductance 10 or a plurality of inductances 10 connected in series. Each inductance 10 has at least one winding 11; each inductance 10 is further provided with a switch 17 connected and conducting with the winding 11. The switch 17 is adapted to control the inductance 10 to be in an access state or a short-circuit state, so as to switch the number of inductances 10 connected to the inductance control system 1.
[0032] It can be understood that each inductance 10 in the inductance control system 1 has a switch 17, so as to separately control each inductance 10 in the inductance control system 1. Under the condition that the inductance 10 is in the access state, the winding 11 in the inductance 10 is connected to the inductance control system 1. In the case that the inductance 10 is in the short-circuit state, the winding 11 in the inductance 10 is short-circuited and thus not connected to the inductance control system 1. Furthermore, the number of inductances 10 connected to the inductance control system 1 is switched through the switch 17, so as to facilitate adjusting the inductance value of the inductances 10 in the inductance control system 1.
[0033] Furthermore, the inductors 10 are connected in series, and the circuit connection is relatively simple, facilitating an increase in the number of inductors 10 in the inductor control system 1, enabling the inductor control system 1 to have good scalability. That is to say, by simply changing the number of series-connected inductors 10, the inductor control system 1 can meet the test requirements of different inverter systems, which is beneficial to expanding the applicable range of the inductor control system 1.
[0034] In some embodiments, as Figure 1 and Figure 2 shown, the inductor 10 includes an upper lead row 12, a lower lead row 13, and a plurality of windings 11. The plurality of windings 11 are disposed between the upper lead row 12 and the lower lead row 13. One end of the coil of the winding 11 is connected and conducted with the upper lead row 12, and the other end of the coil of the winding 11 is connected and conducted with the lower lead row 13, so that the plurality of windings 11 are connected in parallel. The switch 17 is connected and conducted with the upper lead row 12 and the lower lead row 13, so that the switch 17 is adapted to control the inductor 10 to be in an access state or a short-circuit state.
[0035] That is to say, the upper lead row 12 is located at one end of the plurality of windings 11 to be connected and conducted with the end of the coil of the winding 11 close to the upper lead row 12, and the lower lead row 13 is located at the other end of the plurality of windings 11 to be connected and conducted with the end of the coil of the winding 11 close to the lower lead row 13, which is beneficial to shortening the wiring distance between the upper lead row 12 and each winding 11, and shortening the distance between the lower lead row 13 and each winding 11. Furthermore, the structure of the inductor 10 can be made more compact, and it is beneficial to improve the electrical connection reliability of the parallel connection between the windings 11. It is worth mentioning that the current is dispersed through the plurality of parallel windings 11, which is beneficial to reducing the heat generation and loss of a single winding 11.
[0036] In some embodiments, as Figure 1 and Figure 2 shown, the upper lead row 12 has an upper power connection board 121 and a plurality of upper connection ends 122 arranged at intervals. The upper power connection board 121 connects and conducts each upper connection end 122, and each upper connection end 122 is connected and conducted with one end of the coil of a winding 11; the lower lead row 13 has a lower power connection board 131 and a plurality of lower connection ends 132 arranged at intervals. The lower power connection board 131 connects and conducts each lower connection end 132, and each lower connection end 132 is connected and conducted with the other end of the coil of a winding 11, so that the windings 11 of the inductor 10 are connected in parallel. That is to say, one end of each winding 11 is connected and conducted with the upper power connection board 121 through an upper connection end 122, and the other end is conducted with the lower power connection board 131 through a lower connection end 132, making the structure of the inductor 10 more compact.
[0037] In some embodiments, as Figure 1As shown, the inductor 10 further includes at least one first conductive member 14 and at least one second conductive member 15. The first conductive member 14 is connected to conduct the upper connection end 122 of the upper lead row 12 and one end of the switch 17, and the second conductive member 15 is connected to conduct the lower connection end 132 of the lower lead row 13 and the other end of the switch 17, so that the switch 17 is adapted to control the inductor 10 to be in an access state or a short - circuit state.
[0038] In at least one embodiment, as Figure 1 shown, the number of the first conductive members 14, the number of the second conductive members 15 are the same as the number of windings 11 of the inductor 10. The coils of each winding 11 in the inductor 10 are respectively connected and conducted with the switch 17 through a set of the first conductive members 14 and the second conductive members 15. It can be understood that, compared with the connection and conduction of each winding 11 with the switch 17 through the same set of the first conductive members 14 and the second conductive members 15, the electrical connection method in this embodiment is beneficial to disperse the current, so as to reduce the current carried by each of the first conductive members 14 and the second conductive members 15, which is beneficial to improving the reliability of the inductor control system 1.
[0039] In a specific embodiment, both the first conductive member 14 and the second conductive member 15 are copper bars. It can be understood that, compared with using wires, the copper bars in this embodiment have a larger cross - sectional area, so as to carry a higher current, and are beneficial to reducing the resistance, thereby reducing the power loss while ensuring the reliability of the inductor control system 1. Further, the copper bars have a larger surface area, which is beneficial to heat dissipation, so as to improve the thermal stability of the inductor control system 1. In addition, the copper bars also have a higher mechanical strength. On the basis of connecting and conducting the upper lead row 12, the lower lead row 13 and the switch 17, they can also assist in supporting the switch 17, so that the switch 17 is located on one side of the winding 11.
[0040] In some embodiments, as Figures 5-8 shown, the inductor control system 1 includes at least two inductors 10 and at least one third conductive member 16. Each inductor 10 is arranged horizontally or vertically or in a rectangular array, so that the structure of the inductor control system 1 is more compact, which is beneficial to reducing the occupied space. The third conductive member 16 is connected to conduct the upper lead row 12 or the lower lead row 13 of one inductor 10 and the upper lead row 12 or the lower lead row 13 of another inductor 10, so that the inductors 10 in the inductor control system 1 are connected in series.
[0041] That is to say, through the third conductive member 16, two inductors 10 are connected in series, and thus the number of inductors 10 connected in series in the inductance control system 1 can be increased or decreased more conveniently, so that the inductance control system 1 has good scalability. Further, through the switches 17 of the respective inductors 10, the inductors 10 can be controlled to be in an access state or a short-circuit state, and thus the number of inductors 10 connected to the inductance control system 1 can be switched more conveniently to adjust the inductance value of the inductors 10 in the inductance control system 1.
[0042] In some embodiments, as Figures 5-8 shown, the number of the third conductive members 16 between two adjacent inductors 10 connected in series is the same as the number of windings 11 of the inductor 10. The coils of the respective windings 11 of one inductor 10 are respectively connected and conducted with the coils of the respective windings 11 of the other inductor 10 through the third conductive members 16 in a one-to-one correspondence. It can be understood that compared with connecting and conducting with one third conductive member 16 between two inductors 10, the electrical connection method in this embodiment is beneficial to dispersing the current, reducing the current carried by each third conductive member 16, and improving the reliability of the inductance control system 1.
[0043] In some embodiments, as Figure 5 and Figure 6 shown, under the condition that two adjacent inductors 10 connected in series are arranged vertically, the upper lead row 12 of one inductor 10 is arranged opposite to the lower lead row 13 of the other inductor 10, and the third conductive member 16 connects and conducts the upper connection end 122 of the inductor 10 located below and the lower connection end 132 of the inductor 10 located above, so that the respective inductors 10 in the inductance control system 1 are connected in series, which is beneficial to reducing the size of the inductance control system 1 in the horizontal direction.
[0044] In a specific embodiment, as Figure 5 and Figure 6As shown, the inductance control system 1 includes a first inductor 101 and a second inductor 102 arranged vertically, and three third conductive members 16. The first inductor 101 is located above the second inductor 102, so that the lower lead row 13 of the first inductor 101 and the upper lead row 12 of the second inductor 102 are arranged opposite to each other in the vertical direction. The first inductor 101 and the second inductor 102 each have three windings 11 arranged horizontally. The three windings 11 of the first inductor 101 and the three windings 11 of the second inductor 102 are arranged opposite to each other in the vertical direction one by one. Each third conductive member 16 connects and conducts a lower connection end 132 of the first inductor 101 and an upper connection end 122 of the second inductor 102 to play a role in shunting, so as to reduce the current carried by each third conductive member 16. Further, the third conductive member 16 is implemented as a copper row, so that the structure of the inductor 10 is more compact and the wiring is neater. Furthermore, the inductance control system 1 is connected to the inverter test system through an upper connection end 122 of the first inductor 101 and a lower connection end 132 of the second inductor 102, which is beneficial to reducing the vertical dimension of the inductance control system 1.
[0045] In some embodiments, as Figure 7 shown, under the condition that the upper lead rows 12 of adjacent two inductors 10 in series are arranged horizontally, the upper lead rows 12 of each inductor 10 are at the same height. The third conductive member 16 connects and conducts an upper connection end 122 of one inductor 10 and an upper connection end 122 of another inductor 10, or the third conductive member 16 connects and conducts a lower connection end 132 of one inductor 10 and a lower connection end 132 of another inductor 10, so that each inductor 10 in the inductance control system 1 is connected in series.
[0046] In a specific embodiment, as Figure 7As shown in the figure, the inductance control system 1 includes a first inductor 101 and a second inductor 102 arranged horizontally, and three third conductive members 16. The first inductor 101 is located on one side of the second inductor 102 in the horizontal direction, so that the upper lead row 12 of the first inductor 101 and the upper lead row 12 of the second inductor 102 are in the same plane, and the lower lead row 13 of the first inductor 101 and the lower lead row 13 of the second inductor 102 are in the same plane. The first inductor 101 and the second inductor 102 each have three windings 11 arranged horizontally. The three windings 11 of the first inductor 101 and the three windings 11 of the second inductor 102 are arranged in a horizontal "one" shape. Each third conductive member 16 connects and conducts an upper connection end 122 of the first inductor 101 and an upper connection end 122 of the second inductor 102 to play a role in shunting, so as to reduce the current carried by each third conductive member 16. Further, the third conductive member 16 is implemented as a wire to be suitable for electrical connection with a large span. Furthermore, the inductance control system 1 is connected to the inverter test system through a lower connection end 132 of the first inductor 101 and a lower connection end 132 of the second inductor 102.
[0047] In another specific embodiment, as Figure 8 shown in the figure, the inductance control system 1 includes a first inductor 101, a second inductor 102, a third inductor 103, and a fourth inductor 104 arranged in a rectangular array, and nine third conductive members 16. Specifically, the first inductor 101 is located above the second inductor 102, so that the lower lead row 13 of the first inductor 101 and the upper lead row 12 of the second inductor 102 are arranged opposite to each other in the vertical direction; the third inductor 103 is located above the fourth inductor 104, so that the lower lead row 13 of the third inductor 103 and the upper lead row 12 of the fourth inductor 104 are arranged opposite to each other in the vertical direction; the third inductor 103 is located on one side of the first inductor 101 in the horizontal direction, and the fourth inductor 104 is located on one side of the second inductor 102 in the horizontal direction.
[0048] Further, the first inductor 101 to the fourth inductor 104 each have three windings 11 arranged horizontally. The three windings 11 of the first inductor 101 and the three windings 11 of the second inductor 102 are arranged opposite to each other in the vertical direction in a one-to-one correspondence. The three windings 11 of the third inductor 103 and the three windings 11 of the fourth inductor 104 are arranged opposite to each other in the vertical direction in a one-to-one correspondence. The three windings 11 of the first inductor 101 and the three windings 11 of the third inductor 103 are arranged in a horizontal "one" shape, and the three windings 11 of the second inductor 102 and the three windings 11 of the fourth inductor 104 are arranged in a horizontal "one" shape. The three upper connection ends 122 of the first inductor 101 and the three upper connection ends 122 of the third inductor 103 are connected and conducted through the third conductive member 16 in a one-to-one correspondence. The three lower connection ends 132 of the first inductor 101 and the three upper connection ends 122 of the second inductor 102 are connected and conducted through the third conductive member 16 in a one-to-one correspondence. The three lower connection ends 132 of the third inductor 103 and the three upper connection ends 122 of the fourth inductor 104 are connected and conducted through the third conductive member 16 in a one-to-one correspondence, so that the first inductor 101 to the fourth inductor 104 are connected in series. Further, the inductor control system 1 is connected to the test system through a lower connection end 132 of the second inductor 102 and a lower connection end 132 of the fourth inductor 104.
[0049] In some embodiments, as Figure 2 and Figure 3 shown, the upper connection end 122 includes a first section 1221, a second section 1222, and a third section 1223 connected in sequence. Among them, the first section 1221 extends from one end of the winding 11 in a direction away from the lower lead row 13. One end of the first section 1221 is connected and conducted with the winding 11, and the first section 1221 is connected and conducted with the upper power connection plate 121. The second section 1222 extends from the other end of the first section 1221 in the direction of the switch 17. The second section 1222 is used to be connected and conducted with the switch 17 through the first conductive member 14. The third section 1223 extends from the end of the second section 1222 far from the first section 1221 in a direction away from the lower lead row 13. The third section 1223 is used to be connected and conducted with another inductor 10 through the third conductive member 16.
[0050] Further, as Figure 2 and Figure 4As shown, the lower connection end 132 includes a fourth segment portion 1321, a fifth segment portion 1322, and a sixth segment portion 1323 that are connected in sequence. Among them, the fourth segment portion 1321 extends from the other end of the winding 11 in a direction away from the upper lead row 12. One end of the fourth segment portion 1321 is connected and electrically conductive to the winding 11, and the fourth segment portion 1321 is connected and electrically conductive to the lower electrical connection plate 131. The fifth segment portion 1322 extends from the other end of the fourth segment portion 1321 toward the direction where the switch 17 is located. The fifth segment portion 1322 is used to be connected and electrically conductive to the switch 17 through the second conductive member 15. The sixth segment portion 1323 extends from the end of the fifth segment portion 1322 that is far from the fourth segment portion 1321 in a direction away from the upper lead row 12. The sixth segment portion 1323 is used to be connected and electrically conductive to another inductor 10 through the third conductive member 16.
[0051] Further, as Figure 2 shown, the second segment portion 1222 and the third segment portion 1223 of the upper connection end 122, and the fifth segment portion 1322 and the sixth segment portion 1323 of the lower connection end 132 all have connection holes 191 to facilitate connection and electrical conduction with the first conductive member 14 or the second conductive member 15 or the third conductive member 16.
[0052] Furthermore, as Figure 6 shown, the sixth segment portion 1323 is closer to the switch 17 than the third segment portion 1223. Under the condition that two adjacent inductors 10 in series are arranged vertically, the sixth segment portion 1323 of the upper inductor 10 and the third segment portion 1223 of the lower inductor 10 are arranged in different planes. The third conductive member 16 is implemented as a copper row bent in a shape similar to a "Z", so as to connect the sixth segment portion 1323 of one inductor 10 and the third segment portion 1223 of another inductor 10. It is worth mentioning that bending the copper row is beneficial to improving the structural strength of the copper row.
[0053] In some embodiments, as Figure 1 shown, the inductor 10 further includes an upper mounting frame 181 and a lower mounting frame 182. The upper ends of the iron cores of the respective windings 11 are connected to the upper mounting frame 181, and the lower ends of the iron cores of the respective windings 11 are fixedly connected to the lower mounting frame 182, so that the respective windings 11 are arranged in an array between the upper mounting frame 181 and the lower mounting frame 182. Further, both the upper mounting frame 181 and the lower mounting frame 182 have mounting holes 192. The mounting holes 192 are used to mount the inductor 10 on the cabinet body, and further to facilitate the installation of multiple inductors 10 on the cabinet body respectively and in series, so that the inductor control system 1 has good scalability. It is worth mentioning that the array arrangement of the respective windings 11 of the inductor 10 includes but is not limited to a linear array, a rectangular array, and a polygonal array.
[0054] In a specific embodiment, as Figure 1 and Figure 2As shown, each winding 11 of the inductor 10 is linearly arrayed between the upper mounting frame 181 and the lower mounting frame 182. The upper lead row 12 is disposed at one end of the winding 11 at an interval from the upper mounting frame 181, and the lower lead row is disposed at the other end of the winding 11 at an interval from the lower mounting frame 182. The switch 17 is located on one side of each winding 11 and is centered along the arrangement direction of the windings 11, so that the structure of the inductor 10 is more compact.
[0055] In some embodiments, the switch 17 of the inductor 10 is mounted on the cabinet body; or the switch 17 of the inductor 10 is connected to the iron core of the winding 11 through a mounting bracket; or the switch 17 of the inductor 10 is connected to the upper mounting frame 181 and / or the lower mounting frame 182 through a mounting bracket.
