Improper use about frequency inverter

date: 2016-05-03
view: 63

 1. cut off the power if we do not use the frequency inverter

a. frequency inverter is electrical product, even you take it as standby application, it is better to make power on for emergency using

b. there are electrolytic capacitors in the inverter, users should charge and discharge it periodically

c. with power on but no using, there is only current in the control circuit, so it will not cause electric energy loss and life reduce

 

2. it is better to choose big capacity frequency inverter

a. use big capacity inverter could meet heavy load application, but the cost is high

b. for normal application, the capacity for inverter and motor should be the same

c. for some special occasion, the capacity of inverter is one level bigger than the motor

 

3. if we use frequency inverter, we can save energy

a. some people think the torque does not reach the motor rated torque(but the operating frequency is also 50Hz), use inverter could save energy, it is wrong

b. some people think it could save energy while there is no load, it is wrong

 

4. the application occasion is dirty, user should clean the dust everyday

If there is not a lot of dust, the dust is not wet, the air duct is not blocked, no need to clean it everyday. Normally we suggest make the cleaning every month. Also please make the power off while you make the cleaning
