Description

Technical Field

[0001] The utility model relates to the technical field of cabinets, in particular to a control cabinet structure. Background Art

[0002] A control cabinet is a device used to house and centrally control various electrical devices. It is commonly used in industrial and commercial environments to centrally house and manage equipment such as electrical control systems, PLCs (Programmable Logic Controllers), inverters, electrical protection devices, relays, and contactors. Control cabinets are typically constructed of metal and feature appropriate isolation and protection to protect the internal equipment from external environmental influences.

[0003] However, in the use of traditional control cabinet structures, when the electrical components inside the control cabinet are short-circuited or other reasons cause a fire in the control cabinet, the electrical components are easily damaged or even exploded. When the electrical components explode, it is easy to cause injuries to firefighters. The safety is low, and it is impossible to achieve simultaneous fire extinguishing of the control cabinet while cutting off the power after the control cabinet catches fire through structural improvements. At the same time, the electrical components in the traditional control cabinet structure are fixed in a fixed position, which is inconvenient for staff to inspect and repair. In addition, the cooling effect in the traditional control cabinet structure is not good. Since the electrical components will generate a lot of heat after working for a long time, if the cooling effect is not good, the working efficiency of the electrical components will be reduced, and even cause fire.
