Description

Technical Field

[0002] The core function of integrated equipment is to enable access, conversion and management of various energy inputs such as power grid, photovoltaic, and generator, and to provide uninterrupted, safe and reliable power supply for critical loads. It typically integrates energy management, static switching, current conversion and various circuit breaker protection modules.

[0003] Currently, most similar functional equipment on the market adopts traditional tower structure or distributed cabinet solutions. This type of existing technology usually installs each functional module, such as EMS controller, STS switch, PCS converter and various circuit breakers, in an independent chassis or cabinet, and then connects these dispersed units into a complete system through external cables.

[0004] However, existing technical solutions suffer from loose structures, large footprints, cumbersome installation processes, and require extensive inter-cabinet interconnection cabling, resulting in low on-site construction efficiency and high installation costs. The dispersed structure makes subsequent maintenance and repair extremely inconvenient, requiring operation on multiple independent units. Furthermore, it is difficult to achieve a uniform high protection level when splicing multiple cabinets, and each connection interface has weak points in protection, making it unsuitable for applications in harsh industrial environments such as dust and humidity.

[0017] The inventors, through analysis of existing technologies, discovered that most similar functional equipment on the market currently employs traditional tower structures or distributed cabinet solutions. These existing technologies typically install each functional module, such as EMS controllers, STS switches, PCS converters, and various circuit breakers, in separate chassis or cabinets, and then connect these dispersed units into a complete system via external cables. However, existing solutions suffer from loose structures, large footprints, cumbersome installation processes, and require extensive inter-cabinet interconnection cabling, resulting in low on-site construction efficiency and high installation costs. The distributed structure makes subsequent maintenance and repair extremely inconvenient, requiring operation on multiple independent units. Furthermore, it is difficult to achieve a uniform high protection level when splicing multiple cabinets, and each connection interface has weak points in protection, making it unsuitable for applications in harsh industrial environments such as dust and humidity.

[0018] In the embodiments of this application, compared with the problems of large footprint, cumbersome installation process, and inconvenient maintenance in the prior art, this application provides an energy management system with a structure incorporating a pull-out component and an air inlet filter cotton matching the shape of the door panel on the inner side of the first door. Specifically, it includes an equipment cabinet, a first door, a second door, functional modules, and a heat dissipation and ventilation system; the first door is located on one side of the cabinet, and the second door is located on the other side of the cabinet, with the first door and the second door facing each other and both hinged to the cabinet; the functional components are located inside the cabinet; the functional modules include an energy management module, a static conversion module, a converter module arranged in sequence, and a load switch, a grid switch, and a surge protection module arranged side by side; the heat dissipation and ventilation system includes an air inlet filter located at the bottom of the first door and a cooling fan located on the second door. The advantage of this application is that it provides a highly integrated, high-protection-level integrated equipment solution. By compactly arranging all core modules within a cabinet that meets protection standards, a small footprint is achieved. The modular design and optimized airflow for heat dissipation greatly simplify the installation process, reduce external wiring, lower the overall cost, facilitate maintenance, and significantly improve the equipment's reliability and market competitiveness in harsh environments.

[0019] Reference Figure 1-6This diagram illustrates the structure of an outdoor high-protection integrated device according to the present invention. Specifically, it includes the following structure: a cabinet 1, a first door 11, a second door 13, functional modules 2, and a heat dissipation and ventilation system. The first door 11 is located on one side of the cabinet 1, and the second door 13 is located on the other side of the cabinet 1. The first door 11 and the second door 13 are positioned opposite each other and are hinged to the cabinet 1. The functional modules 2 are located inside the cabinet 1. The functional modules 2 include an energy management module 21, a static conversion module 22, a converter module 23 arranged sequentially, and a load switch 24, a power grid switch 25, and a lightning protection module 26 arranged side-by-side.
