Notes on the use of amusement equipment frequency converter

Frequency converter, as an electrical component of energy conversion, is an electric power control equipment that uses frequency conversion technology and micro-electronic technology to control ac motors by changing the frequency of the motor’s working power supply.  Inverter by internal IGBT to adjust the voltage and frequency of the output power supply, according to the actual needs of the motor to provide the required power supply voltage, so as to achieve the purpose of energy saving, speed regulation.  In addition, inverter has over current, over voltage, overload protection and many other protection functions.  However, the application of frequency converters in amusement equipment is limited due to the phenomenon of electromagnetic and power grid interference. So, what are the precautions for the use and maintenance of amusement equipment frequency converters?

  1. Precautions for the use of amusement equipment frequency converter  
  2. Filter can be added to avoid interference from external power grid  
  3. Iron shell is usually used for shielding to eliminate the interference of the inverter itself  
  4. Pay attention to solve the interference on the sensor output analog signal  
  5. Use pipe fittings for shielding to eliminate interference in the system power supply circuit  
  6. Pay attention to solve the problems of ambient temperature and heat dissipation of frequency converter  
  7. Pay attention to the relationship between speed and load, and select the appropriate matching motor and working section  
  8. Note that the interlock between power frequency output and frequency conversion output should be qualified  
  9. Pay attention to the grounding wire of the motor and other strong electric control system should be correctly closed
