The Dry Silica Gel In The Ac Reactor Does Not Need To Be Replaced For The Time Being, As It Has Become Powder-free.

The dry silica gel in ac dc reactor is mainly used to adsorb moisture in the air inside the system and control the air humidity during the "breathing" process. This is similar to the principle of silica gel dryers used in high-voltage equipment such as transformers. Silica gel does not chemically react with the system medium; its moisture adsorption capacity comes from its highly porous structure.

Under normal operating conditions, if the dry silica gel in unit ac input reactor remains free of powdering and shows no obvious signs of saturation such as color change, its physical adsorption performance has not yet reached the point of failure. In this case, it is advisable to continue using the existing dry silica gel assembly rather than replacing it immediately. Powder-free means that the silicone particles remain intact, preventing fine dust from entering the ac output reactor and thus avoiding potential component wear risks.

Regularly checking the condition of ac reactor for inverter dry silica gel, including observing color changes and particle morphology, is one of the bases for evaluating whether to replace it. Color change is often used as an important visual indicator of moisture absorption.
