[0002] The switch cabinet is highly closed, compact in structure, and has a small internal space. The relatively closed air circulation is poor, and moisture often enters due to lax sealing, underground moisture, etc. When the air humidity is too high, condensation is likely to occur in the cabinet, causing the insulating parts to become damp, which reduces the performance and life of the components, accelerates metal corrosion, oxidizes the contact surface, and increases the contact resistance, resulting in a serious decrease in the insulation strength of high-voltage electrical equipment, which in turn leads to accidents. Therefore, moisture-proof and dehumidification have become important factors in ensuring the safe and stable operation of the switch cabinet. The existing application number is CN201610232669.2, which is a high and low voltage switch cabinet with good heat dissipation and moisture resistance. A desiccant is arranged at the active air inlet to keep the inside of the switch cabinet dry. However, the desiccant needs to be replaced frequently, which increases the workload. Therefore, a high and low voltage switch cabinet with good heat dissipation and moisture resistance is proposed. Utility Model Content
