The incoming line module is electrically connected to the input end of the three-level module, the output end of the three-level module is electrically connected to the input end of the filtering module, and the output end of the filtering module is electrically connected to the outgoing line module. By arranging the incoming line module, the three-level module, the filtering module, and the outgoing line module in the first chamber and the second chamber arranged side by side, the utilization rate of the internal space of the cabinet can be improved. The modules are arranged compactly with a high density, which can reduce the wiring, thereby reducing the volume of the energy storage inverter cabinet and lowering the cost.

[0004] Currently, for the above-mentioned existing cabinet designs, since the cabinet is directly placed on the ground after the assembly of each module and device, there are insufficient installation stability measures, which are prone to cause the cabinet to topple, thereby weakening the overall safety protection performance of the cabinet and making it face relatively high safety risks in practical applications.

[0005] Therefore, based on the above problems, we designed a grid-forming PCS energy storage inverter cabinet. Summary of the Utility Model

[0006] The utility model aims to solve at least one of the technical problems existing in the prior art. For this reason, the utility model provides a grid-forming PCS energy storage inverter cabinet, which solves the technical problem that in the existing cabinet design, since the cabinet is directly placed on the ground after the assembly of each module and device, there are insufficient installation stability measures, which are prone to cause the cabinet to topple, thereby weakening the overall safety protection performance of the cabinet and making it face relatively high safety risks in practical applications.

[0007] To achieve the above object, according to an embodiment of the first aspect of the present utility model, a grid-forming PCS energy storage inverter cabinet is proposed, which includes a cabinet body. The cabinet body includes a framework and several detachable cabinet doors arranged on the side of the framework;

[0008] It further includes:

A spring is sleeved on the rod body of each damper, and a mounting block is arranged on the top surface of the rod body. The cabinet body is arranged on the reinforcement base, and the sides are respectively connected to the four mounting blocks.

[0011] Further improvement lies in that each mounting clip is provided with a fixing stud, and each mounting plate is provided with an assembly hole for the installation of the fixing stud.

[0012] Further improvement lies in that each mounting clip and the clamping sleeve are internally provided with adsorption magnetic plates.

[0013] Further improvement lies in that each mounting block is provided with a fixing bolt, and each mounting block is connected to the outer side surface of the cabinet body through the fixing bolt.

[0014] Further improvement lies in that a limiting card slot is arranged inside the port of the reinforcement base, and the bottom of the cabinet body is arranged inside the limiting card slot.

[0015] Further improvement lies in that flat suction cups are additionally arranged at the four corners of the bottom surface of the reinforcement base, and the top surface of each flat suction cup is screwed onto the bottom surface of the cabinet body.

[0016] Further improvement lies in that reinforcement rods are additionally connected to the four corners of the top surface of the reinforcement base through fixing bolts, and grooves for sliding the ends of each reinforcement rod are provided on the side surface of the outer plate of the framework.

[0017] Compared with the prior art, the beneficial effects of the present utility model are:

[0018] (1) By using the adsorption magnetic plates inside the clamping sleeves and the mounting clips, the present utility model cleverly adsorbs the clamping sleeves inside each mounting clip, so as to adapt different modules and devices to be embedded into the four clamping sleeves, and then tightly connects the bottoms of each device and module to the mounting plate. This design greatly simplifies the assembly and disassembly process of the modules and devices, and improves the operation convenience;

[0019] (2) The present innovation cleverly configures flat suction cups at the bottom of the reinforcement base.

[0036] As Figures 1 to 4As shown in the figure, in this embodiment, for the grid-forming PCS energy storage inverter cabinet in the application document, each module and device is pre-assembled. After assembly, the working principle is the prior art and has been made public. It should be noted that this application document only targets the existing cabinet. Since the cabinet is directly placed on the ground after the assembly of each module and device, it lacks sufficient installation stability measures, is prone to tipping over, and thus weakens the overall safety protection performance of the cabinet, making it face relatively high safety risks in actual applications. This improvement does not involve other aspects. The working principle of such a grid-forming PCS energy storage inverter cabinet is introduced as follows:

[0037] During installation, the assembler selects a suitable bushing 22 according to the specifications of each module and device. Subsequently, by utilizing the adsorption magnetic plate 202 built into the bushing 22 and the mounting clip 21, the bushing 22 is skillfully adsorbed into each mounting clip 21, so as to accommodate different modules and devices to be embedded into the four bushings 22. Then, the bottom of each device and module is tightly connected to the mounting frame plate 2 through fixing bolts.

Then, the bottom of the cabinet 1 is accurately inserted into the limit card slot 301 of the reinforcement base 3, and at the same time, it is ensured that the lower end of the side of the cabinet 1 is tightly connected to the four shock-absorbing devices. These shock-absorbing devices are built with dampers 32 and springs 33, which can effectively absorb and relieve vibrations, thus preventing the cabinet from tipping over due to external factors and ensuring safe use. In addition, four reinforcement rods 302 added to the surface of the reinforcement base 3, the other ends of which are accurately embedded into the grooves 101 at the upper end of the side of the cabinet 1, provide additional support and reinforcement for the upper part of the cabinet 1, significantly enhancing the overall stability and safety of the cabinet 1 in the placed state.
