變頻器工作正常。變頻器操作手冊上的故障對策表中介紹的皆為較常見的故障,在出現(xiàn)未涉及的一些的代碼時應(yīng)對變頻器作檢查。(6)MM420/MM440變頻器的AOP面板僅能存儲一組參數(shù)變頻器選型手冊中介紹AOP面板中能存儲10組參數(shù),但在用AOP面板作第二臺變頻器參數(shù)的備份時,顯“存儲容量不足”。解決辦法如下:a)在菜單中選擇“語言”項;b)在“語言”項中選擇一種不使用的語言;c)按Fn+Δ鍵選擇刪除,經(jīng)提示后按P鍵確認(rèn);這樣,AOP面板就可存儲10組參數(shù)。造成這種現(xiàn)象的原因可能是設(shè)計時AOP面板中的內(nèi)存不夠。(7)ABBACS600變頻器在運(yùn)行時直流回路過壓跳閘該變頻器配置有制動斬波器和制動電阻,但外方調(diào)試人員在調(diào)試時將電壓控制器選擇為ON而未使用制動斬波器和制動電阻。

1.比較器檢測通過穩(wěn)壓管固定比較器一端的電壓,被檢測的電壓取樣后再與之比較,結(jié)果通過比較器輸出。2.ADC檢測(模擬/數(shù)字轉(zhuǎn)換器)被檢測的電壓通過電阻降壓取樣后,落在ADC可檢測的范圍,可以通過程序設(shè)定電壓的報警范圍。主電路中的儲能電容,對運(yùn)行中變頻器過壓、欠壓影響很大。而變頻器電路的各種零部件又有一定使用壽命的,所以一旦變頻器零部件達(dá)到使用壽命就會帶來故障的發(fā)生。像主電路中的儲能電容或其它零部件的原因都有可能對主電路造成影響,從而使整個變頻器發(fā)生故障。通常變頻器停用時間過長,達(dá)到一年以上,則應(yīng)對儲能電容要做一次體檢。對長時間不用的變頻器,如何來避免這種現(xiàn)象發(fā)生呢?按照要求,停用的變頻器應(yīng)每隔兩三個月通電—次。

等效成兩相靜止坐標(biāo)系下的交流電流Ia1Ib1,再通過按轉(zhuǎn)子磁場定向旋轉(zhuǎn)變換,等效成同步旋轉(zhuǎn)坐標(biāo)系下的直流電流ImIt1(Im1相當(dāng)于直流電動機(jī)的勵磁電流;It1相當(dāng)于與轉(zhuǎn)矩成正比的電樞電流),然后模仿直流電動機(jī)的控制方法,求得直流電動機(jī)的控制量,經(jīng)過相應(yīng)的坐標(biāo)反變換,實現(xiàn)對異步電動機(jī)的控制。其實質(zhì)是將交流電動機(jī)等效為直流電動機(jī),分別對速度,磁場兩個分量進(jìn)行獨立控制。通過控制轉(zhuǎn)子磁鏈,然后分解定子電流而獲得轉(zhuǎn)矩和磁場兩個分量,經(jīng)坐標(biāo)變換,實現(xiàn)正交或解耦控制。矢量控制方法的提出具有劃時代的意義。然而在實際應(yīng)用中,由于轉(zhuǎn)子磁鏈難以準(zhǔn)確觀測,系統(tǒng)特性受電動機(jī)參數(shù)的影響較大,且在等效直流電動機(jī)控制過程中所用矢量旋轉(zhuǎn)變換較復(fù)雜。

t為熱穩(wěn)定電流時間。額定容量電流互感器二次額定容量要大于實際二次負(fù)載,實際二次負(fù)載應(yīng)為25~二次額定容量。容量決定二次側(cè)負(fù)載阻抗,負(fù)載阻抗又影響測量或控制精度。負(fù)載阻抗主要受測量儀表和繼電器線圈電阻、電抗及接線接觸電阻、二次連接導(dǎo)線電阻的影響。使用注意事項編輯使用原則1)電流互感器的接線應(yīng)遵守串聯(lián)原則[8]:即一次繞阻應(yīng)與被測電路串聯(lián),而二次繞阻則與所有儀表負(fù)載電流互感器電流互感器串聯(lián)2)按被測電流大小,選擇合適的變比,否則誤差將增大。同時,二次側(cè)一端必須接地,以防絕緣一旦損壞時,一次側(cè)高壓竄入二次低壓側(cè),造成人身和設(shè)備事故3)二次側(cè)不允許開路,因一旦開路,一次側(cè)電流I1全部成為磁化電流,引起φm和E2驟增。
