1.Power switching and protection function
The frequency conversion control cabinet is usually designed with a circuit breaker component, which is connected to the incoming power supply, which can help the frequency converter cabinet complete the circuit on-off operation, and can be short-circuited or overloaded in the circuit and frequency converter provide protection.
2.Frequency conversion speed regulation function
The control panel of the inverter cabinet is equipped with a potentiometer for frequency conversion speed regulation, which can send command signals to the motor according to the output frequency of the operator to control the speed of the motor. Some products in the inverter cabinet are equipped with a power frequency switching function to ensure that the motor is switched back to the power frequency power supply through the automatic control circuit when the frequency converter fails.
3.Intuitive control function
The cabinet body of the inverter cabinet is designed with a display device and an operation panel, which are connected with the electrical components inside the inverter cabinet, which can visually display the operating status of the inverter cabinet, and at the same time facilitate the operator Control the operation of the frequency conversion device, and conduct on-site operations on the controlled equipment such as the motor.
4.Safety protection function
The inverter cabinet gathers all kinds of electrical components including inverters in the cabinet, which can reduce the influence of the external environment on the electrical components and reduce the degree of environmental pollution of the electrical components , It also reduces the risk of electric shock for the operator of the inverter cabinet, so it has a better safety protection effect.
The application fields of Lingshida’s special frequency converter for fans and pumps
The special frequency converter for fans and pumps is mainly used in various fan and pump loads in central air-conditioning, urban wastewater treatment systems, urban water supply systems, and factory blast and exhaust systems.
