變頻控制柜系統(tǒng)中的變頻調(diào)速能夠應(yīng)用在大部分的電機(jī)拖動(dòng)場(chǎng)合，由于它能提供準(zhǔn)確的速度控制，因此可以方便地控制機(jī)械傳動(dòng)的上升、下降和變速運(yùn)行。變頻應(yīng)用可以地提高工藝的效率(變速不依賴(lài)于機(jī)械部分)，同時(shí)可以比原來(lái)的定速運(yùn)行電機(jī)更加節(jié)能。下面例舉使用變頻調(diào)速的10個(gè)理由，來(lái)說(shuō)明變頻器應(yīng)用日趨普及的基本認(rèn)識(shí):(1)控制電機(jī)的啟動(dòng)電流。當(dāng)電機(jī)通過(guò)工頻直接啟動(dòng)時(shí)，它將會(huì)產(chǎn)生7到8倍的電機(jī)額定電流。這個(gè)電流值將增加電機(jī)繞組的電應(yīng)力并產(chǎn)生熱量，從而降低電機(jī)的壽命。而變頻調(diào)速則可以在零速零電壓?jiǎn)?dòng)(也可適當(dāng)加轉(zhuǎn)矩提升)。一旦頻率和電壓的關(guān)系建立，變頻器就可以按照V/F或矢量控制方式帶動(dòng)負(fù)載進(jìn)行工作。使用變頻調(diào)速能充分降低啟動(dòng)電流，提高繞組承受力，用戶直接的好處就是電機(jī)的維護(hù)成本將進(jìn)一步降低、電機(jī)的壽命則相應(yīng)增加。(2)降低電力線路電壓波動(dòng)。在電機(jī)工頻啟動(dòng)時(shí)，電流劇增的同時(shí)，電壓也會(huì)大幅度波動(dòng)，電壓下降的幅度將取決于啟動(dòng)電機(jī)的功率大小和配電網(wǎng)的容量。電壓下降將會(huì)導(dǎo)致同一供電網(wǎng)絡(luò)中的電壓敏感設(shè)備故障跳閘或工作異常，如PC機(jī)、傳感器、接近開(kāi)關(guān)和接觸器等均會(huì)動(dòng)作出錯(cuò)。而采用變頻調(diào)速后，由于能在零頻零壓時(shí)逐步啟動(dòng)。淄博不銹鋼控制柜供應(yīng)</p><p
