Why does the frequency converter go wrong when parked for a long time?

Article Source：Kinri Energy | Author：Kinri Energy | Issuing Time：2024.05.22
I believe many people have this question: how can a good frequency converter go wrong when placed? Actually, the reason behind this is not simple.


frequency converter

Firstly, electronic components will age. Just like how our bodies age over time, the electronic components inside the frequency converter will gradually age, deteriorate, or even fail due to environmental changes such as temperature and humidity after being placed for a long time, which poses a hidden danger for the explosion of the machine.

Secondly, there is a problem with the capacitor. There are many capacitors in the frequency converter, which are like the "heart" of a machine. If not used for a long time, the electrolyte of the capacitor may dry up or deteriorate, the capacity will decrease, the leakage current will increase, and the crystal will be damp. If there is no standardized capacitor restructuring, once it is re used, it is extremely easy to cause the frequency converter to explode.

Thirdly, dampness is also a major issue. If the storage environment is relatively humid, the internal circuits are easily affected by moisture, and short circuits and other faults may occur when powered on, with unimaginable consequences.

So, everyone must pay attention that when the frequency converter is restarted after being parked for a long time, a comprehensive inspection and maintenance must be carried out, including cleaning, checking the status of electronic components, testing capacitors, etc., and gradually debugging and testing should be carried out to ensure its safe and reliable operation.
