The humid environment of hydropower stations makes traditional electrical secondary control cabinets susceptible to damage during heat dissipation, shortening the lifespan of electronic components and causing economic losses.
A secondary electrical control cabinet for a hydropower station was designed, which combines heat dissipation pipes and a drying box. The heat dissipation pipes are equipped with guide frames and magnetic structures. An auxiliary mechanism ensures that the desiccant is evenly spread inside the heat dissipation pipes and scrapes off any adhering substances when the tubes are pulled out. The desiccant moves automatically inside the drying box for easy replacement.
It effectively prevents humid air from entering the control cabinet, extends the life of electronic components, improves heat dissipation, facilitates desiccant replacement, and avoids inconvenience caused by adhesion.
