Judging The State And Timing Of Replacing Dry Silica Gel In An Alternating Current Reactor

As a crucial moisture-proof component within the electrical line reactor system, the working condition of dry silica gel directly impacts system stability. Many operators monitor the color change of the silica gel during routine inspections, as this is a direct way to determine its moisture absorption level.

Dry silica gel typically uses a color-changing indicator design. When not absorbing moisture, it appears blue or orange, gradually turning pink as it absorbs moisture. In the sealed environment of inverter ac reactor, silica gel continuously captures water molecules within the system through physical adsorption, preventing moisture from corroding the electrical components of reactor ac. When the silica gel particles retain their original color, it indicates that their moisture absorption capacity is not yet saturated, and their internal porous structure still provides sufficient adsorption space.

Maintenance personnel need to establish a regular observation mechanism for vfd reactor. Checking the silica gel's condition through the observation window or by opening the access panel indicates that the moisture absorption is within a safe range. Replacing it hastily in this case not only increases maintenance costs but also causes unnecessary downtime. Conversely, replacement should only be planned when the silica gel shows extensive discoloration, especially when more than 70% of the particles turn pink.
