The auxiliary cabin 901 is provided below the control cabin 801.

[0048] When the distributed application outdoor equipment 100 is working, the liquid cooling unit in the liquid cooling cabin 101 transmits coolant through pipelines to perform heat exchange on multiple energy storage batteries, thereby achieving a cooling effect on the energy storage cabin.

[0058] In one embodiment, the second end of the converter is connected to the first end of the static conversion unit STS and the power grid through a three-phase four-wire system, specifically, the 380V AC power of the power grid is connected. In the traditional energy storage system, the converter is connected in a three-phase three-wire manner, so the present application adopts a three-phase four-wire connection, and the corresponding function can be realized without a transformer, which is conducive to reducing the volume of the outdoor cabinet, and is conducive to realizing the flexible setting of the modules in the outdoor cabinet to meet the application requirements of multiple scenarios.

[0059] The distributed outdoor equipment provided in this application is designed in a modular manner, and energy storage, photovoltaic, AC / DC load, charging pile access and related auxiliary systems are assembled in modules to form a system product that is easy to operate and install.

[0060] Figure 3 is a three-dimensional schematic diagram of an outdoor cabinet provided in an embodiment of the present application from one perspective; Figure 1 and Figure 3 As shown, because the energy storage battery compartment containing the battery clusters PACK1-PACK5 is arranged on the left side of the cabinet, the left side of the cabinet is heavier than the right side. For transportation safety considerations, the cabinet forklift hole 01 is not designed to be centered here, but the cabinet forklift hole 01 is arranged on the left side of the outdoor cabinet. Because the cabinet is designed as three independent compartments, the air inlet 02 of the liquid cooling unit arranged on the front door of the liquid cooling compartment 101 only cools down the liquid cooling unit in the liquid cooling compartment 101, and will not have a temperature impact on the energy storage battery compartment 201 where the battery cluster is placed. Furthermore, the front door of the energy storage battery compartment 201 of the outdoor cabinet is designed with an insulation layer 03, and the thickness and material of the insulation layer 03 are set according to the actual application scenario, which is beneficial to keep the battery cluster in the energy storage battery compartment 201 warm and reduce power consumption. Specifically, the thickness of the insulation layer 03 is set to 50mm, and 50mm insulation cotton is placed in the insulation layer 03. The energy storage battery compartment 201 is provided with a guide rail 04 for installing multiple battery PACKs, and the guide rail 04 is symmetrically installed on the left and right sides of the energy storage battery compartment 201, thereby providing installation support for the battery PACK. Because the high-voltage box is opened many times and is set at a relatively high position in the outdoor cabinet, a hinge 05 installation structure is designed for the baffle of the high-voltage box in the high-voltage box compartment 301, which is conducive to improving the portability of operation. At the same time, handles 06 are respectively provided for the cabinet body of the outdoor cabinet, thereby facilitating the installation and disassembly of the components in the cabinet body and improving the installation efficiency. Sealing strips 07 are provided on the edges of multiple compartments in the cabinet body to ensure the waterproofness of the cabinet body. Four electrical compartment baffles 09 are provided on the right side of the cabinet body of the outdoor cabinet, thereby dividing the installation of the entire electrical components, thereby facilitating the confirmation of the electrical installation position and ensuring the accuracy of the installation position; at the same time, the disassembly parts can be reduced during maintenance, and all wiring harnesses are blocked in the cabinet. When the cabinet is opened, no wiring harness can be seen, ensuring the simplicity and beauty of the appearance. At the same time, an air inlet is opened on the first baffle plate 08 of the external access cabin (501) to ensure the heat dissipation needs of the electrical components. The opening is directly facing the air inlet of the electrical components, which can maximize the heat dissipation of the electrical components by the air duct.

[0061] Figure 4 is a three-dimensional schematic diagram of another perspective of the outdoor cabinet provided in the embodiment of the present application; Figure 1 , Figure 3 and Figure 4 The cabin on the right side of the outdoor cabinet where multiple electrical components are placed is designed with a rear door air outlet 10 to ensure the heat dissipation of the electrical components in the cabinet. At the same time, a heat dissipation duct 11 is provided for the liquid cooling unit in the liquid cooling cabin 101, and the air outlet 12 of the liquid cooling unit is sealed so that the hot air of the liquid cooling unit is directly dissipated from the air outlet 12 of the liquid cooling unit. At the same time, the baffle provided on the liquid cooling cabin ensures that the hot air will not return to the inside of the cabinet, which is conducive to ensuring that the heat generated by the liquid cooling unit is dissipated out of the cabinet as soon as possible. A pressure relief valve 13 is designed in the energy storage battery cabin 201. When the battery fails due to heat, high temperature and high pressure will be generated in the cabinet. The pressure relief valve 13 will relieve the pressure in the cabinet to ensure the safety of the cabinet. At the same time, support members 14 are welded on the front and rear doors of the cabinet, and nylon wheels are provided in the door. The nylon wheels and support members 14 are in contact with each other to support the door cabinet and prevent the door hanging feet from deformation.

[0062] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0063] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention and are not intended to limit the present invention. As long as they are within the spirit of the present invention, appropriate changes and modifications to the above embodiments are within the scope of protection required by the present invention.
