Problems solved by technology
[0003] The switchgear cabinet structure is the combination basis of low-voltage complete switchgear. It not only meets the combined functional conditions of each electrical unit, but also meets the inherent requirements of the cabinet body, including firmness, reliability, neatness and beauty, and easy adjustment. An important part of the cabinet body, it plays the role of connecting the frame and protecting the electrical components in the cabinet. However, in the prior art, due to the simple structure of the guard plate, there are problems such as poor heat dissipation and ventilation effect, low rigidity, and difficult fast and stable installation. Improve the service life and safety of low-voltage switchgear
