A Humid Environment Will Accelerate The Corrosion Process Of The Inverter's Metal Terminals.

High humidity can cause moisture in the air to seep into the interior of frequency converter 50hz to 60hz three phase and adhere to the metal terminals and conductive connections. When the temperature changes or the equipment is shut down for cooling, these water vapors may condense into liquid water, further triggering oxidation and chemical corrosion on the metal surface of industrial frequency converter. Trace amounts of ions and contaminants in humid air can exacerbate this reaction, leading to rust and material erosion on the terminals.

Over time, this corrosion process can alter the conductivity and mechanical properties of the terminal contact surfaces, causing poor contact, changes in resistance, and even localized overheating. Once oxidation occurs, an oxide layer or corrosion products form on the surface of the metal terminal. These layers may interfere with current conduction or create microcracks under vibration and thermal cycling. Furthermore, the metal structure at the terminal connection points experiences greater mechanical stress during repeated moisture absorption and drying cycles, accelerating material fatigue.
