What are the consequences of the deterioration of the capacitor parameters of the air conditioner fan?

To make the air conditioner operate normally, the air conditioner fan capacitor is one of the indispensable components. Once its parameters deteriorate during use, it will produce unfavorable factors. Today we will introduce it. What are the consequences of the deterioration of the parameters.

1. Capacitance drop and loss increase

The capacitance of the air-conditioning motor capacitor will decrease with time. This is mainly because the electrolyte is constantly repaired and the anodic oxide film is constantly increasing during the long-term load process.

Especially for aluminum electrolytic air conditioner fan capacitors, especially after a long time of use, the amount of electrolyte loss will continue to become thick, the resistivity will increase, and the capacitance loss will be obvious.

When the electrolyte with relatively high viscosity is in the etched oxide film layer, the effective area of ​​the electrode plate will become smaller, which will lead to a decrease in the capacitance. Once the capacitance of the capacitor decreases significantly, it shows that its service life is also fast. it's over.

Second, the leakage current increases

The leakage current of the air conditioner motor increases, which will lead to the failure of the air conditioner fan capacitor.

When the manufacturer's process level is not fine enough during production and processing, the fineness and firmness of the oxide film are relatively poor.

In addition, the process of chip opening is relatively backward, which is easy to cause damage to the oxide film and contamination. The raw material purity of the electrolyte is relatively low, and the amount of impurities will cause the leakage current of the capacitor to exceed tolerance and fail.

Once the chloride ion in the air conditioner fan capacitor is stained, it will further cause the decomposition of the oxide film, resulting in an increase in current, and eventually perforation, shortening the service life, and even some unexpected accidents.
