The 115V medium frequency static power module's temperature exceeded 55°C. The fan speed increases linearly with temperature changes. Fault detection for fan failure is in place; after a fan failure, the fan failure current limiting output is activated, along with a fault alarm. Due to the fan's operating speed being related to load size, the fan's lifespan is longer compared to pure air-cooling, and its reliability is significantly enhanced.
The aviation power rectifier utilizes a cooling method that combines fans with natural cooling. This not only effectively reduces the internal operating temperature of the rectifier in high ambient temperatures, extending the lifespan of the device, but also allows the rectifier's fan to operate at a reduced speed in low ambient and load conditions, thereby extending the fan's lifespan.
Aluminum wires have low conductivity, high electrical losses, poor tensile strength, and low corrosion resistance. The joint areas are particularly prone to oxidation, and when connected with copper wires, the joint areas are more susceptible to corrosion due to potential differences, which can easily lead to circuit faults. These issues are relative to low-voltage lines, but aluminum wires also offer clear advantages in high-voltage lines. We must clarify this point and not make a blanket statement.
