How to use four-way inverter to save more power
As an electronic circuit, Quadruple Inverter itself consumes power (about rated power) 3-5%). A 1.5-pound air conditioner has a power consumption of 20-30W, which is equivalent to a long lamp. It is a fact that the inverter operates at the power frequency and has a power saving function. However, the preconditions are: top, high power and fan/pump load; second, the device itself has power saving function (software support); Long-term continuous operation. These are the three conditions that reflect the power saving effect. If you do not add preconditions to say that the inverter power frequency operation energy saving, it is exaggerated or commercial speculation. Know the original, you will use it to serve you. Be sure to pay attention to the use of the occasion and the conditions of use in order to use it correctly, otherwise it is obedience. Power factor compensation energy saving
Reactive power not only adds line loss and heat generation of the equipment, but more importantly, the power factor decreases and the active power of the power grid decreases. A large amount of reactive power is consumed in the line. The use efficiency is low and the waste is severe. After using the variable frequency speed control device, due to the effect of the internal filter capacitor of the inverter, then the reactive power loss is reduced, and the active power of the power grid is added. Soft start energy saving
The hard start of the motor has a severe impact on the power grid, and the grid capacity requirements are too high. The high current and sensation that occurs during startup are extremely harmful to the baffles and valves. The service life of the pipeline is extremely unfavorable. After using the variable frequency energy-saving equipment, the soft start function of the frequency converter will start the starting current from zero and not exceed the rated current, which can reduce the impact on the power grid and 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 leave 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.
