How to maintain the frequency converter will not damage, or regular maintenance?
1. cooling fan, inverter power module is the most serious heating device, the continuous heat generated by the work must be promptly discharged, the general fan life of about 10Kh-40Kh. According to the continuous operation of converter for 2-3 years, it is necessary to replace the fan2. filter capacitor, intermediate circuit filter capacitor: also called electrolytic capacitor, its main function is to smooth the DC voltage, absorb the low-frequency harmonic in dc.
The correct use method and reasonable maintenance can extend the service life of the inverter to a certain extent. The common maintenance methods of the inverter are cleaning the air filter, cooling the air duct and the interior dust. Check whether the screws, bolts and plug are loose, the input and output reactor ground and interphase resistance is short circuit, the normal should be more than tens of megabytes of europe. The conductor and insulator are corrosion phenomenon, if in time to wipe clean with alcohol.
If the conditions permit, use the oscilloscope to measure the stability of the switching power supply output voltage, such as: 5V, 12V, 15V, 24V and other voltage. Is there any distortion in the square wave of the measuring circuit?. Periodic inspection is recommended and shall be conducted once a year.
Replacement of spare parts is a common maintenance method of general inverter, inverter composed of various components, some parts of the work for a long time after its performance will gradually decrease, aging, which is the main reason of inverter fault, in order to ensure the normal operation of equipment for a long time, the device should be replaced regularly:
The use of the environment on the frequency conversion is very large, the general installation environment requirements: minimum environmental temperature -5 degrees, the highest ambient temperature 40 degrees. The failure rate of the frequency converter rises with the increase of temperature, and the service life decreases with the increase of the temperature. The temperature of the environment rises by 10 degrees, and the service life of the inverter will be halved. In addition, the operation of the inverter is good, and the degree of environmental cleanliness also has a lot to do. Equipment failures can only be reduced through good maintenance work.When the frequency converter is broken, it is better not to give no maintenance experience to repair! Otherwise, it may get worse and worse
