What is a frequency conversion vfd cabinet?
Variable frequency cabinet is a control cabinet used to regulate the operating frequency of equipment. By changing the power supply frequency, it controls the speed of the motor, thereby achieving energy-saving and efficient operation of the equipment.
Operating Principle
Based on the proportional relationship between the rotational speed of an electric motor and the supply frequency, the frequency converter changes the frequency of the output power supply, thereby altering the power supply frequency of the motor, and precisely adjusting the rotational speed of the motor. For example, in a constant - pressure water supply system, according to the feedback signal of the pipe network pressure, the control unit adjusts the output frequency of the frequency converter, changes the rotational speed of the water pump motor, and keeps the pipe network pressure constant.
Structural Composition
Frequency Converter: It is the core component. It converts the power supply with the power frequency into a power supply with a variable frequency, enabling precise control over the rotational speed of the motor. It is also equipped with protection functions against overload, short - circuit, overheating, etc.
Control Unit: Usually contains a Programmable Logic Controller (PLC), a single - chip microcomputer, etc. Based on the set parameters and feedback signals, it sends control commands to the frequency converter to achieve logical control and arithmetic functions.
Display and Operation Panel: It is used to display operating parameters such as frequency, voltage, and current. It also allows users to set parameters, start and stop operations, etc. It consists of components like a touch screen, buttons, and indicator lights.
Protection Devices: Include circuit breakers, fuses, thermal relays, etc. When faults such as overload, short - circuit, or undervoltage occur in the circuit, they automatically cut off the circuit to protect the safety of equipment and personnel.
Other Auxiliary Equipment: Such as reactors, filters, contactors, relays, etc. Reactors suppress current harmonics, filters reduce electromagnetic interference, and contactors and relays are used to control the on - off of the circuit and perform signal conversion.
