1, frequency control cabinet power switching and protection functions
Frequency control cabinet is usually designed with circuit breaker components, which connects the incoming power supply, can help the inverter control cabinet to complete the circuit on and off operation, and in the circuit and inverter short circuit or overload to provide protection. In addition, the frequency converter cabinet can also cut off the power supply to ensure the safety of the operator.
2, frequency control cabinet frequency control function
The control panel of the frequency conversion control cabinet is provided with a potentiometer for frequency conversion and speeding, and the command signal can be transmitted to the motor according to the output frequency of the operator to control the rotational speed of the motor. Some of the products in the frequency control cabinet are equipped with frequency switching function to ensure that the motor is switched back to the power supply through the automatic control circuit when the inverter is faulty.
3, variable frequency control cabinet of the intuitive control function
The cabinet of the frequency conversion control cabinet is designed with a display device and an operation panel. It is connected with the electrical components inside the inverter control cabinet, and can display the running status of the frequency conversion control cabinet intuitively. At the same time, it is convenient for the operator to control the operation of the frequency conversion device, Controlled equipment for field operation.
Frequency control cabinet cabinet, also installed a variety of instrumentation and indicators, such as voltmeter, ammeter, frequency table, and power indicator, alarm indicator, running lights, frequency lights and so on. Frequency control cabinet operation and operating status, you can directly respond to the various instruments and lights, to achieve the work of the inverter from time to time monitoring.
4, frequency control cabinet security protection
Frequency control cabinet will include a variety of inverter, including a variety of electrical components are concentrated in the cabinet, which can reduce the external environment on the impact of electrical components, reduce the degree of environmental pollution of the electrical components, but also reduce the frequency control cabinet operator The risk of electric shock, so it has a better security effect.
Do the maintenance and maintenance of frequency control cabinet, can better drive the inverter control cabinet for a long time, saving the cost.
