2020-12-22

In order to strengthen your understanding and understanding of the frequency converter, let's talk about the daily inspection of the inverter control cabinet for you. For details, please see the summary of the following points:


After the use of frequency converter, there must be daily maintenance and overhaul. First of all, in the process of inspection, we should check the inverter wiring, strengthen the fasteners, and at the same time, we should observe whether the components have signs of overheating. This is to avoid any problems when using the inverter control cabinet. In addition, it should also check whether the terminal block is damaged, whether the conductor is skewed, and whether the outer layer of the wire is damaged.


Not only this, but also check whether the filter capacitor leaks liquid and whether it expands when using the inverter control cabinet. The electrostatic capacity measured by the capacity tester should be more than 85% of the rated capacity; whether the contact is rough and broken; whether there is crack in the insulation of resistor and resistor, and whether there is broken wire are also the inspection operations that should be possessed by the inspection and maintenance of inverter control cabinet Cheng
