[0015] 1. This 10-35kV energy storage and booster integrated unit features a protective structure comprising an upper and lower semi-circular shell, which are rotatably connected at the rear of their tops. A locking mechanism secures the upper and lower semi-circular shells. The cooling component includes symmetrical cooling structures and a chilled water supply assembly.

[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 protection scope of the present utility model.

[0024] Please see Figures 1-5 The 10-35kV energy storage booster unit offers two technical solutions:

[0025] The first implementation includes an energy storage module 1, a boost module 2, and a control unit 5. A connection mechanism is provided between the energy storage module 1 and the boost module 2. The connection mechanism includes a protective structure 3 and a cooling component 4. The wires used to connect the energy storage module 1 and the boost module 2 pass through the protective structure 3, and the high temperature generated when the wires are energized is reduced by the cooling component 4.

[0026] The protective structure 3 includes an upper semi-circular shell 31 and a lower semi-circular shell 32. The upper semi-circular shell 31 and the lower semi-circular shell 32 are rotatably connected at the rear of their tops. A latch 34 is provided between the upper semi-circular shell 31 and the lower semi-circular shell 32 for locking. The cooling component 4 includes a symmetrical cooling structure and a cold water supply component 45. The two cooling structures are respectively located inside the upper semi-circular shell 31 and the lower semi-circular shell 32. The cooling structures are used to cool the wires passing through the protective structure 3. Semi-circular rings 33 are fixedly connected to the surfaces at both ends of the upper semi-circular shell 31 and the lower semi-circular shell 32. The semi-circular rings 33 on the lower semi-circular shell 32 have through holes inside. The two semi-circular rings 33 are fixed to the boost module 2 and the energy storage module 1 respectively by bolts.

[0027] The latch 34 includes two fixed seats 341 on the left and right. Both fixed seats 341 are fixedly connected to the surface of the upper semi-circular shell 31. A middle rod 342 is fixedly connected between the opposite sides of the two fixed seats 341. A hanging plate 343 is rotatably connected to the surface of the middle rod 342. A hook 344 is fixedly connected to the surface of the lower semi-circular shell 32, and the hook 344 can be deformed.

[0028] The cooling structure includes multiple water pipes 41, which are connected by staggered connecting pipes 42. The last water pipe 41 is connected to an inlet check valve 43, and the first water pipe 41 is connected to an outlet check valve 44. The cold water supply assembly 45 consists of a protective box and a water tank, pressure pump, and compressor installed inside the protective box. The outlet and inlet of the cold water supply assembly 45 are respectively connected to a double-ended inlet pipe 46 and a double-ended return pipe 47. The two outlets of the double-ended inlet pipe 46 are respectively connected to the upper and lower inlet check valves 43, and the two inlets of the double-ended return pipe 47 are respectively connected to the two outlet check valves 44.

[0029] A connection mechanism is provided between the energy storage module 1 and the boost module 2, allowing the connecting wires to pass through the inside of the protective structure 3. The protective structure 3 can be easily opened for wiring. Furthermore, the cooling component 4 can quickly cool down the heated wires, preventing excessive losses due to the wire temperature change and improving the practicality of the device.

[0030] The second embodiment differs from the first embodiment in that: the energy storage module 1 includes an outer shell 11 and a SiC power conversion unit 14 disposed inside the outer shell 11. The SiC power conversion unit 14 is connected to the DC bus via a copper busbar 13. The outer shell 11 is made of aluminum alloy. The inner wall of the outer shell 11 is provided with a honeycomb sound-absorbing layer 12. The thickness of the honeycomb sound-absorbing layer 12 is 5 mm to 10 mm. The diameter of each honeycomb unit is 3 mm to 6 mm. The bottom of the boost module 2 is provided with a shock-absorbing base 21. The shock-absorbing base 21 is made of rubber material and has a thickness of 10 mm to 20 mm.

[0031] The outer casing 11 is made of aluminum alloy, and its inner wall is provided with a honeycomb sound-absorbing layer. The honeycomb sound-absorbing layer 12 absorbs the noise generated by the energy storage module 1 during operation, which significantly reduces the overall noise level of the equipment. At the same time, the shock-absorbing base 21 at the bottom of the boost module 2 disperses the vibration generated during operation through rubber material, reducing the mechanical impact on the equipment and extending the service life of the equipment.

[0032] When connecting the wires between the energy storage module 1 and the boost module 2, rotate the upper semi-circular housing 31 to open it, allowing the wires to pass through the lower semi-circular housing 32. After the wires are connected, rotate the upper semi-circular housing 31 to close it with the lower semi-circular housing 32. Rotate the hanging plate 343 to contact the hook 344, causing the hook 344 to deform upwards. The hanging plate 343 can then pass over the hook 344 and enter the inside of the hook 344, thus locking it in place. Additionally, when the wire temperature rises, the cold water supply component 45 sends cold water into the water pipe 41 through the double-ended inlet pipe 46. The cold water flows between the multiple water pipes 41, quickly removing the heat from the wires. Simultaneously, the cold water that has undergone heat exchange flows back to the cold water supply component 45 through the double-ended return pipe 47 for recooling, thus achieving a circulating cooling effect.
