在日常使用中，變頻器控制柜的維修和保養(yǎng)關(guān)重要。檢查變頻器控制柜周?chē)沫h(huán)境溫度和濕度。只有實(shí)時(shí)掌握變頻器的工作情況，才能更好地判斷變頻器控制柜的工作狀態(tài)。需要檢查環(huán)境溫度是否在-1050之間，環(huán)境濕度是否低于90%，并觀察是否有結(jié)冰。這是變頻器控制柜正常工作效率的溫濕度范圍。
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.
使用變頻器控制柜時(shí)，應(yīng)注意定期檢查，如檢查所有變頻器控制柜設(shè)備和裝置是否有異常振動(dòng)和異常聲音，觀察變頻器控制柜的運(yùn)行狀態(tài)以避免隱患，檢查電源、電壓和主電路電壓是否正常運(yùn)行。檢查完這些，還要看變頻器的接線，加強(qiáng)緊固件，觀察元器件是否過(guò)熱。
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.
電機(jī)變頻器的工作頻率
Working frequency of motor frequency converter
電機(jī)變頻器在使用時(shí)具有高的工作頻率和低的工作頻率。普通電機(jī)變頻器大頻率是60Hz，有的甚是400Hz。高頻會(huì)使電機(jī)高速運(yùn)轉(zhuǎn)。對(duì)于普通電機(jī)，其軸承不能長(zhǎng)時(shí)間勻速運(yùn)轉(zhuǎn)。電機(jī)的轉(zhuǎn)子能承受這樣的離心力嗎?
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?
小工作頻率是電機(jī)運(yùn)行的小速度。電機(jī)低速運(yùn)轉(zhuǎn)時(shí)散熱性能很差，長(zhǎng)時(shí)間低速運(yùn)轉(zhuǎn)會(huì)燒壞電機(jī)。并且在低速時(shí)，電纜中的電流會(huì)增加，這也會(huì)導(dǎo)致電纜發(fā)熱。
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.
變頻器控制柜有哪些保護(hù)功能
What are the protection functions of inverter control cabinet
需要安裝變頻器控制柜，可以更好的幫助企業(yè)減排，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.
是變頻器控制柜的保護(hù)功能。變頻控制柜將包括變頻器在內(nèi)的各種電氣元件集中在柜體中，可以減少外部環(huán)境對(duì)電氣元件的影響，降低電氣元件的環(huán)境污染程度，降低變頻控制柜操作人員觸電的風(fēng)險(xiǎn)，因此具有較好的保護(hù)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，變頻器控制柜具有可視化控制功能。變頻控制柜的柜體上設(shè)計(jì)有顯示裝置和操作面板，與變頻控制柜內(nèi)部的電氣元件連接，可以直觀地顯示變頻控制柜的運(yùn)行狀態(tài)，方便操作人員控制變頻裝置的運(yùn)行和對(duì)電機(jī)等被控設(shè)備進(jìn)行現(xiàn)場(chǎng)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.
變頻器控制柜的機(jī)柜上還安裝有電壓表、電流表、頻率表、功率指示器、報(bào)警指示器、運(yùn)行指示器和工頻指示器等各種儀表和指示器。變頻控制柜的運(yùn)行和操作狀態(tài)可以直接反映在各種儀表和指示燈上，并可以隨時(shí)監(jiān)控變頻器的工作狀態(tài)。
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.
