The turning radius of the cables is also increasing, requiring more space and higher construction costs. At present, the mainstream solution for energy storage cabins generally adopts a bottom-in and bottom-out method, which requires digging a manhole near the energy storage cabin. Considering the turning radius of the cable wiring, a cable trench needs to be made during the construction of the energy storage cabin foundation, which further increases the cost.
[0003] In order to solve the above problems, the present application proposes a cable connection structure for an energy storage cabin. Utility Model Content
[0004] The technical problem to be solved by the utility model overcomes the existing defects and provides a cable connection structure for an energy storage cabin. An L-shaped copper busbar is used to replace the cable wiring turns in the prior art, and the energy storage cabin is wired by selecting a side-outlet cable method, which effectively saves construction costs and energy storage cabin space, and can effectively solve the problems in the background technology.
[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:
[0006] A cable connection structure for an energy storage cabin mainly comprises a box body, a battery cluster installed inside the box body, a cable interlayer arranged at the bottom of the box body, a junction cabinet installed inside the box body, a battery cluster external cable for electrically connecting the battery cluster and the junction cabinet, and an L-shaped copper bus fixedly connected between the junction cabinet and the cable interlayer. The battery cluster is electrically connected to the L-shaped copper bus inside the junction cabinet through the battery cluster external connection cable. The bottom of the L-shaped copper bus passes through the threading hole at the bottom of the junction cabinet and extends into the cable interlayer. The top of the L-shaped copper bus is fixedly connected to the battery cluster external cable by bolts. The bottom of the L-shaped copper bus is fixedly connected to the energy storage cabin external connection cable by bolts. The L-shaped copper bus is used as a transfer structure. At the same time, the energy storage cabin is wired by selecting a side-out cable method. Compared with the cable wiring bottom-in and bottom-out method in the prior art, construction cost and energy storage cabin space can be saved.
[0007] As a further improvement of the utility model, the bottom of the L-shaped copper busbar is connected to the external connection cable of the energy storage cabin through an aviation plug.
[0008] As a further improvement of the present invention, a cable through hole is provided at the bottom of the box body, and the cable through hole is located below the combiner cabinet.
[0009] As a further improvement of the utility model, a cable gland or a PVC sheath is provided inside the cable through hole for sealing.
[0010] As a further improvement of the utility model, a detachable wiring cover is installed on the top of the cable interlayer, and the wiring cover is arranged above the bottom of the L-shaped copper busbar.
[0011] As a further improvement of the present invention, connection holes are provided on the top and the bottom of the L-shaped copper busbar.
[0012] Beneficial effects of the utility model:
[0013] 1. A cable connection structure for an energy storage cabin, which uses an L-shaped copper busbar as a transfer structure and uses a side-out cable method to connect the energy storage cabin.

[0024] like Figure 1-Figure 5As shown, a cable connection structure for an energy storage cabin mainly comprises a box body 1, a battery cluster 2 installed inside the box body 1, a cable interlayer 3 arranged at the bottom of the box body 1, a junction box 4 installed inside the box body 1, a battery cluster external cable 5 for electrically connecting the battery cluster 2 and the junction box 4, and an L-shaped copper bus 6 fixedly connected to the junction box 4 and the cable interlayer 3. The battery cluster 2 is electrically connected to the L-shaped copper bus 6 inside the junction box 4 through the battery cluster external connection cable 5. The bottom of the L-shaped copper bus 6 passes through the threading hole at the bottom of the junction box 4 and extends into the cable interlayer 3. The top of the L-shaped copper bus 6 passes through the threading hole at the bottom of the junction box 4 and extends into the cable interlayer 3. The battery cluster is fixedly connected to the external cable 5 by bolts, and the bottom of the L-shaped copper busbar 6 is fixedly connected to the external connection cable 7 of the energy storage cabin by bolts. The L-shaped copper busbar 6 is used as a transit structure, and the energy storage cabin is wired by a side-out cable method. Compared with the cable wiring bottom-in and bottom-out method in the prior art, since the L-shaped copper busbar 6 is used to replace the cable wiring turns in the prior art, there is no need to consider the turning radius of the cable, and the side-out method is used to replace the traditional bottom-out method. There is no need to dig a cable trench during the construction of the energy storage cabin foundation, which effectively saves construction costs and energy storage cabin space.
[0025] In some optional embodiments, the bottom of the L-shaped copper bar 6 is connected to the energy storage compartment external connection cable 7 through an aviation plug, as shown in FIG. Figure 4 As shown, one end of the aviation plug is fixedly installed in the cable through-hole 11, and a cable of corresponding length is prefabricated and crimped on the left end of the aviation plug. The cable is fixedly connected to the L-shaped copper bus 6 by bolts, and the other end of the aviation plug is crimped on the energy storage cabin external connection cable 7. The energy storage cabin external connection cable 7 can be quickly connected to the L-shaped copper bus 6, and the cable connection is fully prefabricated, which saves on-site cable production and connection time. In addition, since the aviation plug has a fool-proof structural feature, using aviation plugs with different key positions or models of cables with different polarities can prevent the problem of cable connection errors during on-site wiring construction, reduce on-site construction risks, and reduce accidents.
[0026] In some optional embodiments, a cable through hole 11 is provided at the bottom of the box body 1, and the cable through hole 11 is located below the combiner cabinet 4. Figure 1 As shown, the cable through hole 11 is provided at the bottom of the side of the energy storage cabin, and the cable through hole 11 is used to connect the energy storage cabin to the external connection cable 7.
[0027] In some optional embodiments, a cable gland or a PVC sheath is provided inside the cable through hole 11 for sealing.
[0028] In some optional embodiments, a detachable wiring cover 8 is installed on the top of the cable interlayer 3, and the wiring cover 8 is arranged above the bottom of the L-shaped copper busbar 6. The detachable wiring cover 8 facilitates wiring of the bottom of the L-shaped copper busbar 6.
[0029] In some optional embodiments, connection holes 12 are formed at the top and the bottom of the L-shaped copper busbar 6 .
[0030] When in use, first fix the battery cluster external cable 5 on the top of the L-shaped copper busbar 6 with bolts, open the wiring cover 8, extend the battery cluster external cable 5 from the cable through hole 11 into the cable interlayer 3, use bolts to extend the energy storage cabin external connection cable 7 into the cable interlayer 3 and fix one end to the connection hole 12 at the bottom of the L-shaped copper busbar 6. After multiple cables are connected, put a wire tube on the cable for protection. Compared with the construction method of digging cable trenches in the prior art, it effectively saves construction costs. When aviation plugs are used for connection, the cable connection is fully prefabricated by prefabricated crimping, which saves on-site cable production and connection time, can eliminate the problem of cable connection errors during on-site wiring construction, reduce on-site construction risks, and reduce accidents.
