目前,大多數(shù)國內(nèi)企業(yè)中,由于維修人員素質(zhì)、能力、實(shí)踐經(jīng)驗(yàn)及設(shè)備管理不到位等原因,在設(shè)備維修工作上,主要采取設(shè)備元部件整體更換的維修工作方式。對于設(shè)備中變頻器維修,也普遍采取整機(jī)報廢、更換(或更新)維修方式。故企業(yè)內(nèi)廢舊整機(jī)變頻器數(shù)量很多,每年要花費(fèi)大量資金購置新的變頻器,以維持實(shí)際設(shè)備運(yùn)行需要。另外,由于變頻器在使用中故障頻繁,從維修人員到管理層普遍認(rèn)為只有進(jìn)口機(jī)型,才有高質(zhì)量、低故障的保障。
有了A/D、D/A單元,余下的處理都是數(shù)字量,這對有信息處理能力的PLC并不難。中、大型PLC處理能力更強(qiáng),不僅可進(jìn)行數(shù)字的加、減、乘、除,還可開方,插值,還可進(jìn)行浮點(diǎn)運(yùn)算。有的還有PID指令,可對偏差制量進(jìn)行比例、微分、積分運(yùn)算,進(jìn)而產(chǎn)生相應(yīng)的輸出。計算機(jī)能算的它幾乎都能算。
由傳感器定義可知,傳感器要能感受到被測量,并能轉(zhuǎn)換成電量輸出,因此傳感器一般由敏感元件和轉(zhuǎn)換元件兩大部分組成。但很多時候也可將轉(zhuǎn)換電路及輔助電源作為其組成部分,因?yàn)楫?dāng)今傳感器件絕大多數(shù)都是將轉(zhuǎn)換電路、輔助電源與敏感元件、轉(zhuǎn)換元件一起做成一體化的器件。
變頻器的SPWM控制方式的特點(diǎn)是控制電路結(jié)構(gòu)簡單、成本較低,機(jī)械特性硬度也較好,能夠滿足一般傳動的平滑調(diào)速要求,已在產(chǎn)業(yè)的各個領(lǐng)域得到廣泛應(yīng)用。

在使用變頻器過程中,經(jīng)常會碰到變頻器無輸出現(xiàn)象。驅(qū)動電路損壞、逆變模塊損壞都有可能引起變頻器無輸出,此外輸出反饋電路出現(xiàn)故障也能引起此類故障現(xiàn)象。有時在實(shí)際中遇到變頻器有輸出頻率,沒有輸出電壓(實(shí)際輸出電壓非常小,可認(rèn)為無輸出),這時則應(yīng)考慮一下是否是反饋電路出現(xiàn)了故障所致。在反饋電路中用于降壓的反饋電阻是較容易出現(xiàn)故障的元件之一;檢測電路的損壞也是導(dǎo)致變頻器顯示OC(+pA或+pd或+pn)保護(hù)功能動作的原因,檢測電流的霍爾傳感器由于受溫度,濕度等環(huán)境因素的影響,工作點(diǎn)容易發(fā)生飄移,導(dǎo)致OC報警。
此時,應(yīng)避免和變頻器使用共同的接地線,并在接地時盡可能使二者分開。當(dāng)電源條件不太好時,應(yīng)在PLC的電源模塊以及輸入/輸出模塊的電源線上接入噪聲濾波器和降低噪音用的變壓器等。此外,如有必要在變頻器一側(cè)也應(yīng)采取相應(yīng)措施。當(dāng)把變頻器和PLC安裝在同一操作柜中時,應(yīng)盡可能使與變頻器有關(guān)的電線和與PLC有關(guān)的電線分開。通過使用屏蔽線和雙絞線達(dá)到提高抗噪聲水平的目的
交流接觸器按負(fù)荷種類一般分為一類、二類、三類和四類,分別記為AC1 、AC2 、AC3和AC4 。
