How to deal with the overheating of the frequency converter of the air compressor

If the frequency converter fails, it will also affect the operation of the entire air pressure system. Aiming at the overheating problem of the frequency converter of the air compressor, Sollant Air Compressor summarizes the common causes and solutions.

1. The ambient temperature is too high

If the ambient temperature is too high, the temperature of the components inside the inverter will be too high. In order to protect the internal circuit of the inverter, the inverter will alarm and stop at this time.

To reduce the temperature of the use environment, fans can be installed or the ground can be washed with water.

2. Poor ventilation

If the air duct of the inverter itself is blocked, or the air duct of the control cabinet is blocked, it will affect the heat dissipation inside the inverter and cause the inverter to overheat and alarm.

Regularly inspect the frequency converter, remove the garbage in the air duct, and smooth the air duct.

3. The cooling fan is blocked or damaged

When the cooling fan of the inverter does not work normally, a large amount of heat will accumulate inside the inverter and cannot be dissipated.

Check and repair the cooling fan of the inverter, and replace it if it is damaged.

4. The load is too heavy

When the load carried by the frequency converter is too heavy, it will generate excessive current and generate a lot of heat, and sometimes the frequency converter will also alarm for overheating.

Reduce the load or increase the capacity of the inverter.
