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.

使用变频器控制柜时，应注意定期检查，如检查所有变频器控制柜设备和装置是否有异常振动和异常声音，观察变频器控制柜的运行状态以避免隐患，检查电源、电压和主电路电压是否正常运行。检查完这些，还要看变频器的接线，加强紧固件，观察元器件是否过热。

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.

电机变频器的工作频率

Working frequency of motor frequency converter

电机变频器在使用时具有高的工作频率和低的工作频率。普通电机变频器大频率是60Hz，有的甚至是400Hz。高频会使电机高速运转。对于普通电机，其轴承不能长时间匀速运转。电机的转子能承受这样的离心力吗?

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?

小工作频率是电机运行的小速度。电机低速运转时散热性能很差，长时间低速运转会烧坏电机。并且在低速时，电缆中的电流会增加，这也会导致电缆发热。

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.

变频器控制柜有哪些保护功能

What are the protection functions of inverter control cabinet

需要安装变频器控制柜，可以更好的帮助企业节能减排，起到很好的降耗作用。

Need to install inverter control cabinet, can better help enterprises to save energy and reduce emissions, play a good role in reducing consumption.

首先是变频器控制柜的保护功能。变频控制柜将包括变频器在内的各种电气元件集中在柜体中，可以减少外部环境对电气元件的影响，降低电气元件的环境污染程度，降低变频控制柜操作人员触电的风险，因此具有较好的保护效果。

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.

此外，变频器控制柜具有可视化控制功能。变频控制柜的柜体上设计有显示装置和操作面板，与变频控制柜内部的电气元件连接，可以直观地显示变频控制柜的运行状态，方便操作人员控制变频装置的运行和对电机等被控设备进行现场操作。

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.

变频器控制柜的机柜上还安装有电压表、电流表、频率表、功率指示器、报警指示器、运行指示器和工频指示器等各种仪表和指示器。变频控制柜的运行和操作状态可以直接反映在各种仪表和指示灯上，并可以随时监控变频器的工作状态。

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.
