In daily use, the maintenance of inverter control cabinet is very important. Check the ambient temperature and humidity around the inverter control cabinet. Only by mastering the working condition of the inverter in real time, can we judge the working condition of the inverter control cabinet better. It is necessary to check whether the ambient temperature is between - 10 and 50, whether the ambient humidity is lower than 90%, and observe whether there is ice. This is the temperature and humidity range of normal working efficiency of inverter control cabinet.
When using the inverter control cabinet, pay attention to regular inspection, such as checking whether all the inverter control cabinet equipment and devices have abnormal vibration and abnormal sound, observing the operation status of the inverter control cabinet to avoid hidden dangers, and checking whether the power supply, voltage and main circuit voltage are in normal operation. After checking these, we also need to see the wiring of the inverter, strengthen the fasteners, and observe whether the components are overheated.
Working frequency of motor frequency converter
Motor frequency converter has high working frequency and low working frequency in use. The frequency of common motor frequency converter is 60Hz, some even 400Hz. High frequency makes the motor run at high speed. For ordinary motor, its bearing can not run at constant speed for a long time. Can the rotor of the motor bear such centrifugal force?
Small working frequency is the small speed of the motor. When the motor runs at low speed, the heat dissipation performance is very poor, and the motor will burn out if it runs at low speed for a long time. And at low speed, the current in the cable will increase, which will also lead to cable heating.
What are the protection functions of inverter control cabinet
Need to install inverter control cabinet, can better help enterprises to save energy and reduce emissions, play a good role in reducing consumption.
The first is the protection function of inverter control cabinet. The frequency conversion control cabinet concentrates all kinds of electrical components including frequency converter in the cabinet, which can reduce the impact of external environment on electrical components, reduce the environmental pollution degree of electrical components, and reduce the risk of electric shock for operators of frequency conversion control cabinet, so it has good protection effect.
In addition, the inverter control cabinet has visual control function. The cabinet body of the frequency conversion control cabinet is designed with a display device and an operation panel, which are connected with the internal electrical components of the frequency conversion control cabinet, and can visually display the operation status of the frequency conversion control cabinet, which is convenient for the operators to control the operation of the frequency conversion device and conduct on-site operation of the controlled equipment such as the motor.
The cabinet of inverter control cabinet is also equipped with voltmeter, ammeter, frequency meter, power indicator, alarm indicator, operation indicator, power frequency indicator and other instruments and indicators. The running and operating status of the inverter control cabinet can be directly reflected on various instruments and indicator lights, and the working status of the inverter can be monitored at any time.
