AI Technical Summary

⚠Technical Problem

In power distribution cabinets used in new energy applications, oxidation of metal components and aging of insulation materials can lead to increased contact resistance, localized overheating, or leakage risks. Furthermore, insulation resistance decreases in humid environments, endangering safety.

⚗Method used

The system employs a silica gel ball dehumidification system inside the drying cylinder. The motor drives the fan blades and agitator to increase the contact area between the air and the silica gel balls. Combined with a magnetic access door and fixing mechanism, the silica gel balls can be easily replaced, achieving both dehumidification and heat dissipation.

🎯Benefits of technology

It effectively prevents internal components of the distribution cabinet from being affected by moisture, extends their service life, improves safety and lifespan, simplifies the replacement process of silicone balls, and reduces workload.

Abstract

The application relates to the new energy technical field and discloses a power distribution cabinet for new energy, which comprises a power distribution cabinet, a display panel is arranged on the front side of the power distribution cabinet, a cabinet door is rotationally installed on the front side of the power distribution cabinet, a mounting frame is arranged in the power distribution cabinet, and a heat dissipation base is fixedly installed at the bottom of the power distribution cabinet. Through the operation of a motor, external cold air enters the inside of the power distribution cabinet through a ventilation opening and a drying cylinder. Before entering the power distribution cabinet, the air contacts silica gel balls in a movable way in a partition plate, the silica gel balls complete the air dehumidification operation through the material characteristics, and in addition, a disturbing rod disturbs the silica gel balls in the partition plate. Compared with a traditional device, the device increases the contact area between the air and the material by disturbing the dehumidification material, effectively avoids the influence of humidity on the precise elements in the power distribution cabinet, and prolongs the service life of the elements in the power distribution cabinet.
