[0002] The main functions of electrical cabinets include protecting components from damage, controlling fault range, implementing measurement and control and data acquisition, and preventing short circuits. Electrical cabinets are made of steel and are used to protect components from damage. They are generally made of hot-rolled steel plates and cold-rolled steel plates. Cold-rolled steel plates are more suitable for electrical cabinet manufacturing due to their softer material. Electrical cabinets have a wide range of applications, including but not limited to the chemical industry, environmental protection industry, power system, and transportation industry. Electrical cabinets are easily stolen or opened by unauthorized personnel and may not promptly trigger audible and visual alarms, which can easily lead to damage or theft of the equipment.

[0003] Electrical cabinets are typically secured with keys or combination locks. Unauthorized personnel opening the equipment can damage or steal it, or the cabinet doors may become loose and easily blown open by the wind.
