In these industrial fields, the electric control box contains one or more low-voltage switchgear and related electrical components such as control, measurement, signal, protection, and regulation, so that the electric control box is used to integrate and control various types and specifications of equipment, thereby ensuring that the equipment is protected under abnormal conditions such as overcurrent, overvoltage, and short circuit.

[0003] The basic structure of an electric control box usually consists of a cabinet, measuring instruments, protective electrical appliances and auxiliary equipment. These components are assembled in a closed or semi-closed cabinet to form a low-voltage power distribution device. According to the usage scenario and structural characteristics, the electric control box can be divided into multiple types, such as fixed plate type electric control box, protective electric control box, drawer type electric control box, power supply and lighting electric control box, etc.

[0004] However, although the electric control box plays a vital role in modern industry, it still has many shortcomings in terms of waterproofing and moisture-proofing. Many existing electric control boxes have poor waterproofing and insulation performance, and it is not easy to prevent the invasion of external moisture and humidity, which causes the electrical components inside the electric control box to get damp, reduces its insulation performance, and increases the risk of short circuit and fire. In a humid environment, the electrical components inside the existing electric control box get damp, resulting in performance degradation or even damage. However, the existing electric control box often lacks effective moisture-proof measures, and is unable to remove internal moisture in time to ensure the dryness and stability of the inside of the electric control box, thereby affecting the use effect of the electric control box.
