How to use the inverter to save more power
As an electronic circuit, the inverter itself consumes power (about 3-5% of rated power). A 1.5-pound air conditioner has a power consumption of 20-30W, which is equivalent to a long lamp. The inverter runs at the power frequency, and it is a reality to save power. However, the prerequisites are: 1. High power and fan/pump type load; 2, the device itself has power saving function (software support); br, long-term continuous Running. The above are three conditions for expressing the power saving effect. If you do not add preconditions to say that the inverter power frequency operation is energy-saving, it is exaggerated or commercial speculation. Know the original, you will use it to serve you. It is necessary to pay attention to the use of occasions and conditions to use correctly, or blind obedience. Power factor compensation energy saving
Reactive power not only increases the line loss and the heat of the equipment, but more importantly, the power factor decreases and the active power of the power grid decreases. A lot of reactive power is consumed in the line. The use of power is low and waste is serious. After the frequency conversion speed control device is used, the reactive power loss is reduced due to the effect of the internal filter capacitor of the frequency converter, and the active power of the power grid is increased. Soft-start energy saving
The hard start of the motor has a serious impact on the power grid, and the grid capacity requirements are too high, and the large current and sensation occurring at the time of launching damage the baffle and the valve greatly, the equipment The service life of the pipeline is extremely arrogant. After using the variable frequency energy-saving equipment, the soft-start function of the inverter will start the starting current from zero and not exceed the rated current, which can reduce the impact on the power grid and the requirements of the power supply capacity, and prolong the equipment and valves. Use life and save equipment maintenance costs. In theory, the frequency converter can be used in all mechanical equipment with electric motors. When the motor is started, the current will be 5-6 times higher than the rated value, which will not only affect the operating life of the motor, but also consume more power. The system will have a certain margin on the motor selection during the design, the speed of the motor is fixed, but in the actual application process, sometimes it is necessary to run at a lower or higher speed, so the frequency conversion transformation is right or wrong. Often necessary.
