變頻器應用領域：

電(dian)(dian)梯高(gao)架游覽車類負載　　由于(yu)電(dian)(dian)梯是載人工(gong)具，要(yao)求拖動系統高(gao)度可靠，又要(yao)頻繁的加(jia)減速(su)和正反(fan)轉，電(dian)(dian)梯動態特性(xing)(xing)和可靠性(xing)(xing)的提高(gao)，邊增加(jia)了電(dian)(dian)梯乘坐(zuo)的安全感(gan)、舒(shu)適感(gan)和效(xiao)率。過去電(dian)(dian)梯調速(su)直流(liu)居(ju)多(duo)，近幾年逐漸轉為交(jiao)流(liu)電(dian)(dian)機變(bian)頻調速(su)，無(wu)論日本(ben)還是德國。我國不少電(dian)(dian)梯廠(chang)都爭先恐(kong)后的用變(bian)頻調速(su)來(lai)裝備(bei)電(dian)(dian)梯。

變頻器發熱原因

優化使用環境

以(yi)往經濟條(tiao)件不好(hao)(hao)，很多小廠都沒(mei)有設計獨立的(de)控制室(shi)，即使(shi)(shi)有控制室(shi)，西門子V120變(bian)頻器，也沒(mei)有給控制室(shi)安裝(zhuang)(zhuang)空(kong)調(diao)，現在條(tiao)件好(hao)(hao)了，完全可(ke)以(yi)把變(bian)頻器等器件安裝(zhuang)(zhuang)在帶空(kong)調(diao)的(de)控制器里邊(bian)使(shi)(shi)用，這樣變(bian)頻器的(de)溫(wen)度(du)處于(yu)特佳狀態，不容(rong)易發(fa)熱，也因為粉塵等減少延長了使(shi)(shi)用壽命，細(xi)算起來，實際上是比較好(hao)(hao)的(de)一種投資了。

明(ming)泰(tai)電(dian)(dian)(dian)(dian)氣（蘇州）有(you)限公司(si)(si)是(shi)正泰(tai)集團在蘇州地區(qu)一家授(shou)權的經(jing)銷企業，連續十(shi)年銷量居正泰(tai)營銷網絡名，公司(si)(si)主要(yao)經(jing)營“正泰(tai)”牌配電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)器、控制電(dian)(dian)(dian)(dian)器、終端電(dian)(dian)(dian)(dian)器、電(dian)(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)(dian)器、電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)子、儀器儀表、建筑電(dian)(dian)(dian)(dian)器、高(gao)壓(ya)電(dian)(dian)(dian)(dian)器及成套設備。

如何選擇變頻器的功率。

1.變(bian)(bian)頻器功率值(zhi)與電動機功率值(zhi)相當時，以利變(bian)(bian)頻器在高(gao)的效(xiao)率值(zhi)下運(yun)轉。

2.在(zai)變頻(pin)器的(de)功(gong)(gong)率(lv)(lv)分級與電動(dong)(dong)機(ji)功(gong)(gong)率(lv)(lv)分級不(bu)相同時，則變頻(pin)器的(de)功(gong)(gong)率(lv)(lv)要盡可(ke)能接近電動(dong)(dong)機(ji)的(de)功(gong)(gong)率(lv)(lv)，西(xi)門子V120變頻(pin)器哪(na)家(jia)好，但(dan)應(ying)略大于(yu)電動(dong)(dong)機(ji)的(de)功(gong)(gong)率(lv)(lv)。

3.當電動(dong)(dong)(dong)機(ji)屬頻(pin)繁起動(dong)(dong)(dong)、制動(dong)(dong)(dong)工作或處于重(zhong)載起動(dong)(dong)(dong)且較頻(pin)繁工作時，西(xi)門子V120變頻(pin)器(qi)報價，可選取大一級的變頻(pin)器(qi)，以(yi)利(li)用變頻(pin)器(qi)長期、安全地運行。

4.經測試，電(dian)動機實際功(gong)率確實有富余，可以(yi)考(kao)慮選用功(gong)率小于電(dian)動機功(gong)率的變頻(pin)器(qi)，但要注意(yi)瞬(shun)時峰值(zhi)電(dian)流是(shi)否會造(zao)成過電(dian)流保(bao)護動作(zuo)。

5.當變(bian)頻(pin)器與(yu)電(dian)動機功率不相同時，則必須(xu)相應調整節(jie)能程序的(de)設置，以利達到較高的(de)節(jie)能效果(guo)。
