ZFeng 900 Series 280Kw-T-P General Vector Variable Frequency Drive Environmental Protection and Energy Saving, Intelligent Future -
ZFeng variable frequency drive Green Solution Smooth start-up, reducing impact on the power grid and equipment Principle: The traditional method of directly starting a motor generates a large starting current, usually 4-7 times the rated current, which can have an impact on the power grid, causing voltage fluctuations and affecting the normal operation of other equipment. The frequency converter adopts a soft start method, which gradually increases the input voltage and frequency of the motor to make the motor start smoothly, and the starting current can be controlled within the rated current. Case: When multiple motors are started simultaneously on a large
industrial production line, using a direct starting method can
cause a huge impact on the power grid, which may lead to a decrease
in grid voltage and affect the normal operation of other equipment.
After using a frequency converter, the motor can start smoothly,
avoiding impact on the power grid and equipment, and ensuring the
stable operation of the production line. Complete protection function Principle: The frequency converter is equipped with various protection functions, such as overcurrent protection, overvoltage protection, undervoltage protection, overload protection, overheating protection, etc. When there is an abnormal situation with the motor or frequency converter, these protective functions will automatically activate, cut off the power supply, and protect the motor and frequency converter from damage. Case: In the process of motor operation, if an overload fault
occurs, the overload protection function of the frequency converter
will act in a timely manner to reduce the output power of the motor
or stop the motor operation, avoiding the motor from burning out
due to overload. At the same time, the overvoltage and undervoltage
protection functions of the frequency converter can ensure that the
motor can still operate normally when the grid voltage fluctuates,
improving the reliability and stability of the equipment. Improve production efficiency and product quality Principle: By precisely controlling the speed and torque of the motor, the frequency converter can operate the equipment according to the optimal process parameters, improving production efficiency and product quality. For example, in industries such as plastic processing, printing, and packaging, frequency converters can accurately control the operating speed and tension of equipment according to production process requirements, ensuring the processing quality and consistency of products. Case: In the printing industry, using a frequency converter to
control the printing speed and tension of a printing machine can
make the quality of printed products more stable and reduce the
scrap rate. At the same time, the speed regulation function of the
frequency converter can flexibly adjust the printing speed
according to different printing materials and process requirements,
improving production efficiency. |
