Power factor compensation saves energy

Reactive power not only increases line loss and equipment heating, but more importantly, the reduction of power factor leads to the reduction of the active power of the power grid, a large amount of reactive power consumption in the line, equipment use efficiency is low, waste is serious, after the use of frequency conversion speed control device, due to the role of the internal filter capacitor of the inverter, thereby reducing reactive power loss, increasing the active power of the power grid.

Soft start saves energy

1: The hard start of the motor will cause serious impact on the power grid, but also the capacity requirements of the power grid will be too high, and the large current and vibration generated during the start will cause great damage to the baffle and valve, which is extremely unfavorable to the service life of equipment and pipelines. After using the frequency conversion energy-saving device, the soft start function of the frequency converter will make the starting current start from zero, and the maximum value will not exceed the rated current, which reduces the impact on the power grid and the requirements for power supply capacity, and prolongs the service life of equipment and valves. Save maintenance costs on equipment.

2: Theoretically, the frequency converter can be used in all mechanical equipment with motor, when the motor starts, the current will be 5-6 times higher than the rating, which will not only affect the service life of the motor but also consume more electricity. The system will leave a certain margin in the motor selection when designing, and the speed of the motor is fixed, but in the actual use process, sometimes it is necessary to run at a lower or higher speed, so it is very necessary to carry out frequency conversion transformation. The frequency converter can realize the soft start of the motor and compensate for the power factor.
