The main purpose of the frequency conversion control cabinet is to adjust the output power, reduce the power consumption in the work, and ensure that the equipment can work normally. Its main contribution is to reduce the damage to the motor caused by the high current of the equipment immediately starting. The frequency conversion control cabinet has a very good user reputation in industries such as industrial production, agriculture and animal husbandry, and construction. Let's briefly introduce the functional characteristics of the frequency conversion control cabinet.

Analysis of the functional characteristics of the frequency conversion control cabinet:

1. Switching power conversion and maintenance functions of frequency conversion control cabinet

The general design scheme of the frequency conversion control cabinet has isolating switch components, which are connected to the three-phase five-wire switching power supply, which can assist the frequency conversion control cabinet to conduct the conduction operation of the power circuit, and can be used when the power circuit and the soft starter have a short circuit fault or load. Show maintenance. In addition, the frequency conversion control cabinet can also cut off the power supply during motor maintenance to ensure the safety of operators.

2. The visualized operation function of the frequency conversion control cabinet

The cabinet door of the frequency conversion control cabinet is designed with a display system and an operation panel, which is connected to the electrical components inside the frequency conversion control cabinet, and can visually display the operation of the frequency conversion control cabinet, and at the same time, it is convenient for the operator to control the DC frequency conversion The operation of the equipment, and the on-site operation of the controlled system such as the motor.

On the cabinet door of the frequency conversion control cabinet, various instruments and indicators are also installed, such as ammeter, ammeter, frequency meter, and switching power indicator, alarm indicator, operation indicator, DC indicator, etc. The operation and operating conditions of the soft starter can be immediately reflected on various instrument panels and indicator lights, and complete the real-time monitoring of the working attitude of the soft starter.

3. The DC variable speed function of the frequency conversion control cabinet

The operation panel of the frequency conversion control cabinet is equipped with resistors for DC frequency conversion and variable speed, which can transmit command signals to the motor and control the speed ratio of the motor according to the output frequency of the operator. Some products in the frequency conversion control cabinet are set with a DC conversion function to ensure that the motor is converted back to a DC power supply through the automatic control circuit when the soft starter fails.

4. The safety protection function of the frequency conversion control cabinet

The frequency conversion control cabinet concentrates all kinds of electrical components including soft starters in the cabinet body, which can reduce the damage of environmental factors to electrical components and reduce the degree of air pollution of electrical components , It also reduces the risk of electric shock for the operators of the frequency conversion control cabinet, so it has a good safety effect.

According to the above content, it can help everyone to effectively understand the characteristics, application functions and safety factors of the frequency conversion control cabinet, so that users can operate more safely and efficiently when using the frequency conversion control cabinet.
