The replacement of spare parts for a frequency converter consists of various components, some of which will gradually decrease in performance and age after long-term operation, which is also the main reason for the failure of the frequency converter. In order to ensure the long-term normal operation of the equipment, the following components should be replaced regularly:
The power module of the cooling fan frequency converter is the most severely heated component, and the heat generated by its continuous operation must be discharged in a timely manner. Generally, the lifespan of the fan is about 10Kh-40Kh. According to the conversion of continuous operation of the frequency converter, the fan needs to be replaced every 2-3 years. There are two or three lines for direct cooling fans. One line of the two line fan is the positive pole, and the other line is the negative pole. When replacing, do not connect it incorrectly; In addition to the positive and negative poles, there is also a detection wire for the three wire fan. Be careful when replacing it, otherwise it may cause the frequency converter to overheat and alarm. AC fans are generally divided into 220V and 380V, and the voltage level should not be mistaken when replacing them.
2. Filter capacitor: Intermediate circuit filter capacitor: also known as electrolytic capacitor, its main function is to smooth DC voltage and absorb low-frequency harmonics in DC. The heat generated by its continuous operation and the heat generated by the frequency converter itself will accelerate the drying of its electrolyte, directly affecting its capacity. Under normal circumstances, the service life of the capacitor is 5 years. It is recommended to regularly check the capacitor capacity at least once a year. Generally, if the capacity is reduced by more than 20%, it needs to be replaced.
