Description

Technical Field

[0001] The utility model relates to the technical field of low-voltage cabinets, in particular to a low-voltage cabinet shell with high protection strength. Background Art

[0002] Low-voltage cabinets, also known as low-voltage switch cabinets, are electrical equipment widely used in power plants, petroleum, chemical, metallurgy, textile, high-rise buildings and other industries. They are mainly used for power transmission, distribution and power conversion. When low-voltage cabinets work in a variety of complex environments, the low-voltage cabinet shell is crucial to the safe and stable operation of the power system. From structural design to protection level, to mechanical strength and heat dissipation requirements, every aspect needs to be carefully considered to ensure that the low-voltage cabinet shell can maintain high performance in various situations. Here, a low-voltage cabinet shell with high protection strength is proposed.

[0003] According to the search, Chinese patent literature, announcement number: CN216016094U, discloses a low-voltage cabinet housing with high protection strength. The low-voltage cabinet housing, the first reinforcement frame, the second reinforcement frame, and the reinforcement beam cooperate with each other to make the overall structural strength higher and the appearance more beautiful. The strength of the housing under the same cross-section is significantly enhanced, which reduces the impact of transportation, installation, and earthquakes on the cabinet, and better adapts to work requirements in various situations. However, the device does not have effective electrical protection measures in actual use. Therefore, when the device is struck by lightning, or when its internal equipment ages and leaks electricity, it will cause electrical equipment failure or damage at the least, and electric shock, fire and other accidents at the worst, reducing the overall safety.
