The inverter will always be affected by the use of the environment, such as temperature, humidity, air quality, etc.. Various tiny dust floating in the production plant is hard to be invisible with the naked eye. In general, the relevant administrator of the enterprise usually does not pay attention to the cleaning and maintenance of the inverter, after a period of time will find some dust accumulation on the inverter, especially the top corner. If the dust can not be removed in time, it will have a certain impact on the work of the inverter, and failure will occur seriously. That enterprise related managers should pay attention to what problems when using the inverter for dust removal?

1. Each inverter should be cleaned and maintained once a quarter. Maintenance and cleaning equipment must have detailed records and signatures of responsible personnel. Only when the management is in place, the task can be completed with quality and quantity.

2. Before cleaning, the power must be turned off and wait for the voltage to drop to a safe voltage before starting work.

3. When cleaning, the dust on the surface of the inverter should be cleaned with a brush first, but it is not recommended to clean the inverter with a compressor. Clearing the inverter.

4. If the inverter surface is greasy, wipe it carefully with a cloth dipped in a small amount of alcohol to clean it, and the inverter must be dried before it can be used again.

5. When repairing, check the inverter carefully to see if there are any hot discolored parts inside the inverter, if there are cracks in the cement resistor, and if there are prominent explosion-proof holes in the electrolytic capacitor.

6. For the conditionally removable housing, use compressed air to clean the dust inside and in the air duct. Be careful when using compressed air, because some compressed air contains a lot of moisture, so bleed it before blowing.

However, it is best to use a vacuum cleaner after disassembly and try not to use compressed air. Because blowing with compressed air is the worst effect, the inverter always alarm after blowing, it takes one shift to be normal, it will affect the normal operation of production
