Energy saving, a long-term development strategy goal of sustainable development in China.

The frequency inverter is an important part of the industrial control system, installed in the front end of the frequency conversion can realize the function of speed regulation and energy saving, and has significant advantages in the field of power energy saving.

How does the frequency inverter achieve power saving? Is the installation of a frequency converter can save energy?

1.Energy saving principle of frequency inverter

  Precise regulation

The inverter can accurately control the motor speed according to the need, so that the motor can reduce the power operation when it does not need to run at full speed, so as to achieve the purpose of power saving.

Reduce the number of starts and stops

The frequency converter can achieve smooth speed regulation, which can greatly avoid frequent motor start and stop. The motor consumes a lot of energy during the start and stop process, and the system energy consumption can be effectively reduced by reducing the number of start and stop times.

Adjust output power

The inverter can adjust the output power of the motor according to the actual working load, effectively avoiding the long-term operation of the motor in a state of high power, so as to achieve the purpose of energy saving.

Optimize motor operating conditions

By controlling the speed of the motor, the inverter can optimize the operating conditions of the motor, thereby reducing the efficiency loss of the motor and further reducing the energy loss.

Noise and shock reduction

The frequency converter can reduce the mechanical vibration and noise while controlling the motor speed, which is conducive to optimizing the system efficiency and indirectly affecting the energy saving.

Power factor correction

Using the control mechanism of inverter, the power factor of motor can be corrected, so as to improve the efficiency of motor and reduce the energy consumption of the system.

Optimization of load power and operating parameters

When the motor load rate is low, the energy-saving effect is more obvious. And by optimizing the original operating parameters, such as power, voltage, speed and other adjustable values, can also play a role in energy saving.

2.Frequency inverter energy saving condition

The frequency converter does not have energy saving functions in all cases, and in some cases the use of the frequency converter does not bring significant energy saving effects, but when the frequency converter is operated at the power frequency, it does have energy saving functions. And the need to meet these three conditions at the same time, in order to more obviously feel the energy-saving effect of the inverter.

The equipment is high-power, mainly used for fan and pump load

The device itself has energy saving support, which is usually supported by software

The device needs to run continuously for a long time
