[0049] In the embodiment, first direction a and second direction b of box 10 can be the length direction and the width direction of box 10 respectively. Box 10 can be a standard 20 feet container structure, a plurality of cavities are formed in box 10, so that various structures are distributed in various cavities, thereby optimizing the layout of the internal structure of box 10.

[0050] The transformer chamber 12 can be located on one side of the energy storage converter chamber 11 in the first direction a, so that after the energy storage converter assembly 20 is installed in the energy storage converter chamber 11 and the transformer 30 is installed in the transformer chamber 12, the transformer 30 can be located on one side of the energy storage converter assembly 20 in the first direction a.

[0051] The high-voltage chamber 13 can be located on the side of the transformer chamber 12 away from the energy storage converter chamber 11 in the first direction a, so that after the high-voltage device 40 is installed in the high-voltage chamber 13, the high-voltage device 40 can be located on the side of the transformer 30 away from the energy storage converter assembly 20. Similarly, the low-voltage chamber 14 can be located on the side of the transformer chamber 12 away from the energy storage converter chamber 11 in the first direction a, so that after the low-voltage device 50 is installed in the low-voltage chamber 14, the low-voltage device 50 can be located on the side of the transformer 30 away from the energy storage converter assembly 20. And the low-voltage chamber 14 and the high-voltage chamber 13 are arranged along the second direction b, so that after the low-voltage device 50 is installed in the low-voltage chamber 14 and the high-voltage device 40 is installed in the high-voltage chamber 13, the low-voltage device 50 and the high-voltage device 40 can be arranged along the second direction b.

[0052] In actual application, the energy storage converter assembly 20 can be spaced apart by two groups, three groups, four groups, etc. of energy storage units 21 in the second direction b, which can be set according to the size of the energy storage unit 21 in the second direction b and the size of the energy storage converter chamber 11 in the second direction b. And each group of energy storage units 21 can be adjacent to two, three, four, five, six, seven, eight, nine, etc. energy storage converters 211 in the first direction a, which can be set according to the size of the energy storage converter 211 in the first direction a and the size of the energy storage converter chamber 11 in the first direction a.

[0053] In some embodiments, for the size of the energy storage converter chamber 11 in the second direction b, two groups of energy storage units 21 can be arranged in the energy storage converter chamber 11 along the second direction b, and the two groups of energy storage units 21 are symmetrically distributed. And for the size of the energy storage converter chamber 11 in the first direction a, each group of energy storage units 21 can be adjacent to eight energy storage converters 211 along the first direction a, and the adjacent two energy storage converters 211 can be connected together by bolts, buckles, welding, etc.

[0054] Please refer to Figure 2 , Figure 4In an embodiment of the utility model, energy storage converter chamber 11 is equipped with partition 15, partition 15 divides energy storage converter chamber 11 into first chamber 11a and second chamber 11b distributed in upper and lower, and energy storage converter assembly 20 is arranged in first chamber 11a, and circuit breaker assembly 60 is installed in second chamber 11b.

[0055] Thus, by adopting the integrated partition 15 and the box body 10, the energy storage converter assembly 20 is installed on the partition 15, which can effectively improve the installation strength of the energy storage converter assembly 20; in addition, the partition 15 can also divide the energy storage converter chamber 11 into the first chamber 11a and the second chamber 11b distributed in upper and lower, so as to install the energy storage converter assembly 20 in the first chamber 11a, and install and fix the energy storage converter 211 through the partition 15, and at the same time, the second chamber 11b separated can be used to install the circuit breaker assembly 60, so as to further optimize the layout design of the internal structure of the box body 10, and more structures can be integrated in the standard 20 feet container.

[0056] In some embodiments, the circuit breaker assembly 60 can include a DC molded case circuit breaker 61, a fuse 62, a control panel 63, an AC frame circuit breaker 64, a split excitation relay board 65, a transfer board 66, a wind deflector 67, a copper-aluminum row and a connection cable, etc. The circuit breaker assembly 60 is a common circuit breaker structure, which will not be described one by one.

[0057] Please refer to Figure 2 、 Figure 4 In an embodiment of the utility model, at least two frames 151 are distributed in the second direction b in the first chamber 11a, and an energy storage unit 21 is installed on a frame 151.

[0058] Thus, by using at least two frames 151 to install and fix at least two groups of energy storage units 21, it is more convenient to realize the independent installation of at least two groups of energy storage units 21, and it is also convenient to realize the independent maintenance of at least two groups of energy storage units 21.

[0059] In some embodiments, the at least two frames 151 can be welded on the inner wall of the box body 10 to integrate the partition 15 on the box body 10.

[0060] Please refer to Figure 6In an embodiment of the utility model, first chamber 11a is equipped with first side plate 111 and second side plate 112 that are spaced apart along second direction b, first side plate 111 and second side plate 112 all extend along first direction a, the top of first chamber 11a is equipped with top plate 113, first side plate 111 is equipped with first air inlet 111a, second side plate 112 and top plate 113 are all equipped with first air outlet 113a, one group of energy storage units 21 is arranged close to first side plate 111, and the other group of energy storage units 21 is arranged close to second side plate 112.

[0061] Thus, for the heat dissipation of energy storage converter assembly 20, under the action of the external wind wheel or the internal wind wheel of box body 10, external airflow can enter first chamber 11a from first air inlet 111a of first side plate 111, the airflow entering from first air inlet 111a of first side plate 111 can flow through several energy storage units 21 to take away the heat generated by energy storage units 21 during operation, and the airflow is finally discharged outward from first air outlet 113a of second side plate 112 and first air outlet 113a of top plate 113, that is, effective heat dissipation of energy storage converter assembly 20 can be realized.

[0062] In the embodiment, first side plate 111 and second side plate 112 can be front upper side plate and rear upper side plate of box body 10 respectively, so that front upper air inlet and rear upper air outlet and top air outlet are used to dissipate heat of energy storage converter assembly 20.

[0063] Please refer to Figure 1 、 Figure 6 In an embodiment of the utility model, a confluence passage 22 is formed between the two adjacent groups of energy storage units 21, and at least one first air outlet 113a is arranged correspondingly with the confluence passage 22.

[0064] Thus, by forming the confluence passage 22 between the two adjacent groups of energy storage units 21, the airflow entering from first air inlet 111a of first side plate 111 flows through several energy storage units 21 and then enters the confluence passage 22, so that the airflow is confluenced in the confluence passage 22 and is more smoothly discharged outward from first air outlet 113a.

[0065] Please refer to Figure 2 、 Figure 5 、 Figure 6 In an embodiment of the utility model, second chamber 11b is equipped with third side plate 114 and fourth side plate 115 that are spaced apart along first direction a, third side plate 114 and fourth side plate 115 all extend along second direction b, fourth side plate 115 is located between second chamber 11b and high-pressure chamber 13, third side plate 114 is equipped with second air inlet 114a, and fourth side plate 115 is equipped with second air outlet 115a.

[0066] In this way, heat dissipation of the circuit breaker assembly 60 can be realized by the external wind wheel or the internal wind wheel of the cabinet 10, and the external air flow can enter the second chamber 11b from the second air inlet 114a of the third side plate 114, flow through the circuit breaker assembly 60 in the second chamber 11b, and finally flow out from the second air outlet 115a of the fourth side plate 115, so that the circuit breaker assembly 60 can be effectively cooled.

[0067] In this embodiment, the third side plate 114 and the fourth side plate 115 can be the lower left side plate and the lower side plate close to the transformer chamber 12 of the cabinet 10 respectively, so that the circuit breaker assembly 60 can be cooled by the left lower air inlet and the right lower air outlet. The air flow blown out from the second air outlet 115a of the fourth side plate 115 can directly flow into the transformer chamber 12, and the heat absorbed by the air flow can be dissipated in the transformer chamber 12, so that the transformer 30 in the transformer chamber 12 is not affected.

[0068] In some embodiments, a fan 68 can be arranged at the second air outlet 115a, so that the external air flow can enter the second chamber 11b from the second air inlet 114a of the third side plate 114 under the action of the fan 68.

[0069] Please refer to Figure 1 In an embodiment of the utility model, the high-voltage device 40 is a sulfur hexafluoride gas-filled cabinet.

[0070] In this way, by using the sulfur hexafluoride gas-filled cabinet as the high-voltage device 40, compared with the air ring main unit, since the insulating medium used in the sulfur hexafluoride gas-filled cabinet is sulfur hexafluoride, the insulating effect of the medium is much better than that of air, so the insulating space required by the sulfur hexafluoride gas-filled cabinet can be designed to be smaller, so that the land occupation of the sulfur hexafluoride gas-filled cabinet is small, and the volume of the high-voltage device 40 can be reduced by 40% to 60%; for example, the land occupation of the high-voltage chamber 13 can be reduced to 1.63m 2 Meanwhile, the DV / CCV cabinet can also be compatible.

[0071] Please refer to Figure 2 , Figure 4 , Figure 5 In an embodiment of the utility model, a partition plate 16 is arranged in the low-voltage chamber 14, and the partition plate 16 divides the low-voltage chamber 14 into an upper chamber 14a and a lower chamber 14b arranged in an upper-lower distribution manner; the low-voltage device 50 includes a control device 51 and an auxiliary transformer 52, the control device 51 is arranged in the upper chamber 14a, and the auxiliary transformer 52 is arranged in the lower chamber 14b.

[0072] Thus, by separating the low-voltage chamber 14 into the upper chamber 14a and the lower chamber 14b with the partition 16, the low-voltage device 50 is modularly designed, wherein the control device 51 is installed in the upper chamber 14a and the auxiliary transformer 52 is installed in the lower chamber 14b, so that the space utilization is maximized. Compared with the ordinary left-right distribution mode, the upper-lower modular design can reduce the occupied space of the low-voltage chamber 14 by 50%-60%. In addition, the design of the partition 16 can effectively block the heat generated by the auxiliary transformer 52 from flowing into the upper chamber 14a, thereby preventing the heat from affecting the control device 51 in the upper chamber 14a.

[0073] Please refer to Figure 2 、 Figure 4 、 Figure 6 In an embodiment of the present application, the low-voltage chamber 14 is provided with the fifth side plate 141 and the sixth side plate 142 arranged at an angle, the fifth side plate 141 is located on the side of the low-voltage device 50 away from the transformer 30; the fifth side plate 141 is provided with the third air inlet 141a and the fourth air inlet 141b, the sixth side plate 142 is provided with the third air outlet 142a and the fourth air outlet 142b, the third air inlet 141a and the third air outlet 142a communicate with the upper chamber 14a, and the fourth air inlet 141b and the fourth air outlet 142b communicate with the lower chamber 14b.

[0074] Thus, for the heat dissipation of the control device 51 in the low-voltage device 50, under the action of the external fan or the internal fan of the cabinet 10, external airflow can enter the upper chamber 14a from the third air inlet 141a of the fifth side plate 141, the airflow can flow through the control device 51 in the upper chamber 14a to carry away the heat generated by the control device 51 in the working process, and the airflow finally flows out from the third air outlet 142a of the sixth side plate 142, so that the control device 51 can be effectively cooled. For the heat dissipation of the auxiliary transformer 52 in the low-voltage device 50, under the action of the external fan or the internal fan of the cabinet 10, external airflow can enter the lower chamber 14b from the fourth air inlet 141b of the fifth side plate 141, the airflow can flow through the auxiliary transformer 52 in the lower chamber 14b to carry away the heat generated by the auxiliary transformer 52 in the working process, and the airflow finally flows out from the fourth air outlet 142b of the sixth side plate 142, so that the auxiliary transformer 52 can be effectively cooled.

[0075] Therefore, the present application uses two independent air ducts to cool the control device 51 and the auxiliary transformer 52 respectively, which can reduce the influence of high heat of the auxiliary transformer 52 on the control device 51.

[0076] Please refer to Figure 1 ,Figure 2 、 Figure 4 In an embodiment of the present application, the transformer 30 is provided with heat dissipation fins 31 on both sides, the heat dissipation fins 31 on one side are located between the transformer 30 and the energy storage converter chamber 11, and the heat dissipation fins 31 on the other side are located between the transformer 30 and the high-voltage chamber 13 and the low-voltage chamber 14.

[0077] In this way, the heat dissipation area of the transformer 30 can be effectively increased by using the heat dissipation fins 31 on both sides, which not only improves the heat dissipation effect of the transformer 30, but also realizes high-density integration of the transformer 30 in a compact space to adapt to the design of a standard 20-foot container.

[0078] In some embodiments, the transformer 30 can use a large-capacity double-split oil-immersed transformer 30 with a rated power > 6MW.

[0079] Please refer to Figure 1 In an embodiment of the present application, the ratio of the height to the width of the heat dissipation fin 31 is 0.92-0.99, and the width direction of the heat dissipation fin 31 is consistent with the second direction b. Specifically, the ratio of the height to the width of the heat dissipation fin 31 can be 0.92, 0.93, 0.94, 0.95, 0.96, 0.97, 0.98, 0.99, etc.

[0080] In this way, by increasing the ratio between the height and the width of the heat dissipation fin 31, the height of the heat dissipation fin 31 is designed to be increased, so that the width of the heat dissipation fin 31 can be reduced while ensuring that the heat dissipation fin 31 has sufficient heat dissipation area, thereby being more suitable for the design of a standard 20-foot container.

[0081] Please refer to Figure 2 、 Figure 4 、 Figure 6 In an embodiment of the present application, the transformer chamber 12 is provided with a first mesh door 121 and a second mesh door 122 distributed along the second direction b.

[0082] In this way, by using the design of the first mesh door 121 and the second mesh door 122, the first mesh door 121 and the second mesh door 122 themselves form a plurality of heat dissipation holes in communication with the outside, so that the heat dissipation fins 31 can dissipate heat to the outside after absorbing the heat of the transformer 30, thereby effectively reducing the heat of the transformer.

[0083] Please refer to Figure 1 、 Figure 3 、 Figure 6 In an embodiment of the present application, one side of the box body 10 is provided with a detachable support 17, and the support 17 is used to install the power supply 70.

[0084] Thus, due to the limited internal space of the standard 20-foot container and the large volume of the power supply 70, the detachable support 17 is arranged on one side of the box 10, and the support 17 is mounted on one side of the box 10 during use, so that the power supply 70 is mounted on the support 17; and during transportation, the support 17 can be detached from the box 10, so that the support 17 does not increase the volume of the box 10, thereby facilitating the transportation of the energy storage, conversion and voltage boosting integrated machine 100.

[0085] In actual application, the support 17 can be detachably mounted on one side of the box 10 by means of bolts, buckles and the like. In addition, the support 17 can be foldable and mounted on one side of the box 10, so that the support 17 can be switched between the open state and the folded state, and the support 17 can be moved to the open state during use, and the support 17 can be moved to the folded state during transportation, so that the support 17 does not need to be detached during transportation.

[0086] The above is only an exemplary embodiment of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation, direct / indirect application in other related technical fields based on the technical concept of the present application and the content of the present application are included in the patent protection scope of the present application.
