Frequency conversion control cabinet is relatively common in control equipment. Now both electronic components and equipment need regular maintenance, otherwise it may affect the luck and service life of the equipment. The more common problem in frequency conversion control cabinet is abnormal heat dissipation. What are the factors that affect the heat dissipation of frequency conversion control cabinet?
Frequency conversion control cabinet is relatively common in control equipment. Now both electronic components and equipment need regular maintenance, otherwise it may affect the luck and service life of the equipment. The more common problem in frequency conversion control cabinet is abnormal heat dissipation. What are the factors that affect the heat dissipation of frequency conversion control cabinet?
1. For the operation and maintenance of the fan, the internal fan of the frequency conversion control cabinet is the main way of heat dissipation in the cabinet to ensure the normal operation of the control circuit. Therefore, if the fan is operating abnormally, maintenance should be carried out immediately.
2. Overheating maintenance of the inverter module heat sink is an important part of the inverter control cabinet to generate heat, and it is also an important and weak part of the inverter control cabinet. Therefore, the heat sink of each variable frequency control cabinet is equipped with overheating maintenance equipment.
3. The rated power of braking resistor for overheated maintenance shall be selected according to short-term operation. Therefore, once the power-on time is too long, it will overheat. At this time, it should be suspended and cooled down. Or choose a larger power resistor.
The cooling pipe does not block the outlet, and the ambient temperature can be higher than the allowable value of the frequency control cabinet. The methods to solve the problem and suggestions for improvement are put forward. The application of frequency conversion control cabinet in practical engineering has certain reference value.
5. Pay attention to the interference of the frequency conversion control cabinet to the microcomputer control board. The process level of the microcomputer control board planned by the user is poor and does not conform to the international electromagnetic compatibility standard. After the selection of frequency conversion control cabinet, conduction and radiation interference will generally lead to abnormal operation of the control system, and necessary measures should be taken.
These are the factors that affect the heat dissipation of the frequency conversion control cabinet. I hope this article will help you.
