No matter what kind of machinery and equipment in life, it needs daily maintenance. If it is maintained regularly, key problems or small phenomena will appear in future use. Today, many companies are using frequency conversion control cabinets, and the more common phenomenon of frequency conversion control cabinets is abnormal heat dissipation. Many people cannot make an accurate judgment on this phenomenon. Now the manufacturer of the frequency conversion control cabinet will analyze what affects the cooling of the frequency conversion control cabinet!

1. For the operation and maintenance of the fan, the internal fan of the frequency conversion control cabinet is the key way to dissipate heat in the cabinet, ensuring the normal operation of the control circuit. Therefore, if the fan operation is abnormal, maintenance should be carried out in time.

2. The over-temperature maintenance of the heat sink of the inverter module is an important part of the heat generated by the inverter control cabinet, and it is also an important and weak part of the inverter control cabinet. Therefore, the heat sink of each frequency conversion cabinet is equipped with over-temperature protection equipment.

3. The rated power of the braking resistor for over-temperature maintenance is selected according to short-term operation. Therefore, if the power-on time period is too long, it will overheat. At this time, stop using it and use it after cooling. Or choose a larger power resistor.

4. The inlet and outlet of the cooling air pipe shall not be blocked, and the temperature may be higher than the allowable value of the frequency conversion control cabinet. The way to solve the problem and rationalization suggestions are put forward. The application of frequency conversion control cabinet in actual engineering has certain reference value.

5. Pay attention to the interference phenomenon of the frequency conversion control cabinet on the microcomputer control panel. The microcomputer control board planned by the user has poor craftsmanship and does not meet the international standards for electromagnetic compatibility. After the frequency conversion control cabinet is selected, conduction and radiation interference usually lead to abnormal operation of the control system, and necessary measures should be taken.
