Variable frequency drives (VFDs) are widely used in modern factories. They are a very expensive new type of equipment, and their maintenance is also very costly. Therefore, it is important to pay attention to how VFDs are used.
The physical environment is a significant factor affecting the operation of frequency converters. According to professional technicians specializing in frequency converter repair and their experience, most problems with frequency converters are caused by the logistics environment, mainly including the following three aspects:
1. Operating temperature: Inverters contain many electronic components, some of which will change their performance with temperature changes, and some may even be damaged by temperature. Therefore, it is recommended to control the normal operating temperature of the inverter between 0-55℃. Some items that are prone to heat should not be connected to the inverter.
2. Ambient temperature difference: If the ambient temperature changes too much, condensation will occur inside the frequency converter due to the temperature difference. The frequency converter is prone to burnout due to short circuits or other reasons during startup. Therefore, in places with large temperature differences between day and night, placing some desiccant inside the frequency converter will greatly reduce condensation.
3. Corrosive gases. The electronic components inside the frequency converter have poor corrosion resistance and must not come into contact with corrosive liquids and solids. However, corrosive gases can also damage the components. Therefore, excessive contact between corrosive gases and the frequency converter should be avoided.
