Introduction to the functions of the frequency conversion control cabinet

1. Power switching and protection function of variable frequency control cabinet

Variable frequency control cabinets are usually designed with circuit breaker components, which are connected to the incoming power supply and can help the cabinet complete the on/off operation of the circuit. They can also provide protection in the event of a short circuit or overload between the circuit and the frequency converter. In addition, the frequency conversion cabinet can also cut off the power supply during motor maintenance to ensure the safety of operators.

2. Variable frequency speed regulation function of variable frequency control cabinet

The control panel of the variable frequency control cabinet is equipped with a potentiometer for variable frequency speed regulation, which can transmit command signals to the motor and control the motor speed according to the output frequency of the operator. Some products in the frequency conversion control cabinet are equipped with a power frequency switching function to ensure that in the event of a frequency converter failure, the motor is switched back to the power frequency supply through an automatic control circuit.

3. The intuitive control function of the variable frequency control cabinet

The cabinet body of the variable frequency control cabinet is designed with display devices and operation panels, which are connected to the electrical components inside the variable frequency control cabinet. They can intuitively display the operating status of the variable frequency control cabinet, and facilitate operators to control the operation of the variable frequency device and perform on-site operations on controlled equipment such as motors.

On the cabinet of the variable frequency control cabinet, various instruments and indicator lights are also installed, such as voltage meters, ammeters, frequency meters, as well as power indicator lights, alarm indicator lights, operation indicator lights, power frequency indicator lights, etc. The operation and status of the variable frequency control cabinet can be directly reflected on various instruments and indicator lights, achieving real-time monitoring of the working status of the variable frequency converter.

4. Safety protection function of variable frequency control cabinet

The frequency conversion control cabinet concentrates various electrical components, including the frequency converter, inside the cabinet, which can reduce the impact of external environment on electrical components, lower the degree of environmental pollution on electrical components, and also reduce the risk of electric shock for operators of the frequency conversion control cabinet. Therefore, it has a good safety protection effect.
