Description

Technical Field

[0001] This utility model belongs to the field of microgrid technology, and specifically relates to a switch cabinet used in microgrids. Background Technology

[0002] Microgrids consist of distributed power sources (such as photovoltaic and wind power), energy storage devices (such as lithium batteries and hydrogen fuel cell storage), load systems (such as industrial equipment and lighting loads), and intelligent control modules. They support grid-connected or islanded operation modes, enabling autonomous energy allocation. Switchgear is the core component of a microgrid power distribution system, responsible for power transmission, distribution, and protection. It connects distributed power sources, energy storage devices, and load equipment, ensuring circuit safety. Switchgear contains numerous electrical components that enable corresponding circuit connections and controls. These components generate heat during operation. Common switchgear designs often feature only a single ventilation hole structure connected to the outside, supplemented by cooling fans. However, this single ventilation hole structure cannot achieve effective airflow; the heat dissipation effect at the ventilation hole is far greater than in other areas. Furthermore, most ventilation holes connected to the outside are located on the side, allowing rainwater intrusion during rainy weather, posing a safety hazard to the internal electrical components.

[0003] In summary, we hope to propose a new structure to solve the aforementioned technical problems. Utility Model Content

The left and right sides of the rear side of the switch cabinet 102 are provided with transfer cavities 104 for auxiliary heat dissipation. A cleaning component 300 for auxiliary cleaning is provided inside the transfer cavity 104.

[0030] A maintenance cover plate 400 is installed at the rear end of the transfer chamber 104. A cooling fan 111 is fixedly connected to the lower end of the inner side of the heat dissipation pipe 110.

[0032] The switch cabinet 102 is provided with a rain cover 103 for rain protection. The rear side of the switch cabinet 102 is provided with a cover plate groove 117 around the transfer cavity 104. The maintenance cover plate 400 is interlocked with the cover plate groove 117 and is fixed by screws. The maintenance cover plate 400 is a detachable structure fixed in the cover plate groove 117, which can be disassembled later to assist in maintenance.

[0033] The transfer chamber 104 has a cleaning groove 106 on the lower side of one end near the center of the switch cabinet 102, which is used to assist the cleaning component 300 in moving back and forth. A cleaning slider 301 is provided in the cleaning component 300.

[0034] The cleaning slider 301 and the cleaning chute 106 are movably engaged with each other. The cleaning slider 301 is fixedly connected to a cleaning rack 302 at the end away from the center of the switch cabinet 102. The cleaning rack 302 is fixedly connected to a handle 303 at the lower side of the end near the center of the switch cabinet 102. Pulling the handle 303 causes the cleaning slider 301 to slide back and forth along the cleaning chute 106, so that the cleaning rack 302 assists in cleaning the inner side of the central transfer cavity 104.

[0035] Please see Figures 1-6 As the first embodiment of this utility model: First, during use, the electrical components installed inside the switch cabinet 102 generate heat.
