Detailed understanding of maintaining universal test machine frequency converter

electronicUniversal testing machineThe tester must be familiar with the basic working principles and characteristics of the frequency converter and the operation common sense. Before daily maintenance of the inverter, it is necessary to ensure that the entire equipment power is cut off; and then stop after the inverter has completely disappeared for 3-30 minutes (based on the inverter's power). Pay attention to checking the power grid voltage, improving the surrounding environment of the inverter, motor and line, regularly clearing the internal dust of the inverter, and reducing the fault rate of the inverter to the limit through enhanced equipment management.

Due to the consumption characteristics of some companies, the corrosion gases in each electrical mcc chamber are too large, resulting in corrosion damage to many electrical equipment (including frequency converters).

electronicUniversal testing machineTo solve the above problems, a medium frequency converter can install an air conditioning system and use positive pressure novel wind to improve environmental conditions. In order to reduce the corrosion of corrosive gases on components on the circuit board, inverter consumers can also be requested to stop anti-corrosion processing of the circuit board, and spray preservatives after repair, which effectively reduces the defect rate and improves the efficiency of application.

While maintaining, you must carefully check the inverter, send power regularly, and work at a low frequency of 2hz for about 10 minutes to ensure that the inverter works normally.
