In order to improve the efficiency of installation and connection, integrated substations with inverters and transformers set up on the same platform have emerged. Customers only need to leave the required interfaces at the construction site for quick connection.

[0003] However, existing integrated substations can only be hoisted using lifting tools, which makes installation difficult in some scenarios where lifting tools cannot be used. They often need to be installed separately, increasing installation costs.

[0004] In view of this, it is necessary to improve the existing photovoltaic inverter boost devices to solve the above problems. Utility Model Content

Detailed Implementation

[0017] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] like Figures 1 to 3 As shown, the photovoltaic inverter booster device 100 of this utility model includes a mounting base 1, a transformer cabinet 2 fixed on the mounting base 1, a photovoltaic inverter 3 fixed on the mounting base 1, and a hoisting main beam 4 fixedly connected to the top of the transformer cabinet 2 and the photovoltaic inverter 3.

[0021] The mounting base 1 has a forklift hole 11 that runs horizontally through it, and the transformer cabinet 2 and the photovoltaic inverter cabinet 3 are fixedly connected by a copper busbar 21.

[0022] The photovoltaic inverter booster device 100 of this utility model, by setting a mounting base 1 with a forklift hole 11, can integrate the transformer cabinet 2 and the photovoltaic inverter 3 on the one hand, and can be installed and moved by forklift when hoisting is not possible on the other hand.

[0023] Furthermore, the photovoltaic inverter booster device 100 of this utility model is also equipped with a hoisting main beam 4, which allows for hoisting of the photovoltaic inverter booster device 100 when a hoisting tool is available, realizing multiple installation modes. At the same time, the hoisting main beam 4 is fixedly connected to both the transformer cabinet 2 and the photovoltaic inverter 3, resulting in better hoisting effect. Both are subjected to force simultaneously, without affecting the connection between the transformer cabinet 2 and the photovoltaic inverter 3.

[0024] To prevent dust and debris from entering the mounting base 1 during use, the photovoltaic inverter booster device 100 in this embodiment also includes a shielding plate 12, which blocks the forklift hole 11 during non-forklift installation.

[0025] Furthermore, to better achieve the connection effect between the transformer cabinet 2 and the photovoltaic inverter 3, the copper busbar 21 is a flexible copper busbar 21. The flexible copper busbar 21 has the characteristics of high conductivity, fast heat dissipation, easy forming, and bendability. In this embodiment, the flexible copper busbar 21 is used to electrically connect the transformer cabinet 2 and the photovoltaic inverter 3, thereby eliminating the influence of process errors.

[0026] Furthermore, in this embodiment, there are two photovoltaic inverters 3, which are arranged on both sides of the transformer cabinet 2. Because of the flexible copper busbar 21, even if there are manufacturing errors between the transformer cabinet 2 and the photovoltaic inverters 3, the flexible copper busbar 21 can be connected by simple bending.

[0027] The forklift hole 11 is located below the photovoltaic inverter 3 and is symmetrically arranged. This ensures that the photovoltaic inverter boost device 100 maintains uniform force during forklift installation.

[0028] The mounting base 1 is formed by welding I-beams. The bottom of the transformer cabinet 2 has an exposed air inlet. Two through-holes 13 are formed on the mounting base 1 near the transformer cabinet 2, and each air inlet 13 contains a filter screen 14. In this embodiment, the mounting base 1 allows the transformer cabinet 2 to be raised, and the bottom of the transformer cabinet 2 has an air inlet for ventilation. To ensure effective ventilation, through-holes 13 are provided, and filters 14 are used to filter the air, preventing debris from entering the transformer cabinet 2. Air enters the bottom of the transformer cabinet 2 through the air inlets 13 and then enters the transformer cabinet 2 through the air inlets.

[0029] The transformer cabinet 2 is also equipped with a cooling window, which will not be described in detail here.

[0030] The mounting base 1 is equipped with a support frame, and a cable clamp is fixed on the support frame. In this embodiment, because the mounting base 1 supports the transformer cabinet 2 and the photovoltaic inverter 3, cables can be connected to the transformer cabinet 2 and / or the photovoltaic inverter 3 from below.

[0031] In this embodiment, the cable clamp is located below the transformer cabinet 2. The cable is only connected to the transformer cabinet 2, which is connected to the photovoltaic inverter 3 via a copper busbar 21. The cable clamp serves to support the cable and prevent it from falling off and breaking under gravity.

[0032] The transformer cabinet 2 and the photovoltaic inverter 3 are provided with mounting holes on their tops. The hoisting main beam 4 is provided with a through hole. The photovoltaic inverter booster device 100 also includes a fixing screw 5. The fixing screw 5 passes through the through hole and is threadedly connected to the mounting hole to fix the hoisting main beam 4.

[0033] In this embodiment, the transformer cabinet 2 and the photovoltaic inverter 3 have different widths. Therefore, the rear sides of the transformer cabinet 2 and the photovoltaic inverter 3 are made flush, and the hoisting main beam 4 is fixedly connected to the rear edges of the transformer cabinet 2 and the photovoltaic inverter 3. Because the hoisting main beam 4 is fixedly connected to the transformer cabinet 2 and the photovoltaic inverter 3, the transformer cabinet 2 and the photovoltaic inverter 3 are subjected to force simultaneously during hoisting.

[0034] In other embodiments, if the front sides of the transformer cabinet 2 and the photovoltaic inverter 3 are flush, the hoisting main beam 4 can also be fixedly connected to the front sides of the transformer cabinet 2 and the photovoltaic inverter 3; if the widths of the transformer cabinet 2 and the photovoltaic inverter 3 are equal, two hoisting main beams 4 can be set to be fixedly connected to the front and rear sides simultaneously; or, the hoisting main beam 4 can be set as an irregular structure to connect the transformer cabinet 2 and the photovoltaic inverter 3.

[0035] In this embodiment, the photovoltaic inverter booster device 100 further includes a lifting auxiliary beam 6 fixed to the top of the photovoltaic inverter 3, and the lifting auxiliary beam 6 is spaced apart from the main lifting beam 4. The lifting auxiliary beam 6 is located on the rear side of the photovoltaic inverter 3. During hoisting, the lifting equipment is simultaneously fixed to both the lifting auxiliary beam 6 and the main lifting beam 4, thus ensuring that the photovoltaic inverter booster device 100 is subjected to uniform force from front to back, making the hoisting process more stable.

[0036] The photovoltaic inverter booster device 100 of this utility model can integrate the transformer cabinet 2 and the photovoltaic inverter 3, and can be installed by hoisting or forklift.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
