變頻器發熱原因

變頻器和電機(ji)本身問題

電機用久了(le)，不(bu)排除絕緣性(xing)能不(bu)好，或者軸(zhou)(zhou)承卡滯，本身可能會(hui)出現大電流而發(fa)熱。電機和(he)負(fu)載之(zhi)間的(de)連軸(zhou)(zhou)，也可能有磨(mo)損，或者電機三相(xiang)不(bu)平衡，電機的(de)固定裝置松動等(deng)等(deng)，會(hui)引(yin)起異常聲響和(he)發(fa)熱。

變頻(pin)(pin)器(qi)某些元件老化(hua)，或者(zhe)(zhe)矢量參數(shu)和電機(ji)匹配上有偏離，西(xi)門子V120變頻(pin)(pin)器(qi)價(jia)格，或者(zhe)(zhe)轉矩提升等(deng)參數(shu)設(she)置過大，或者(zhe)(zhe)加減速時間過短，變頻(pin)(pin)器(qi)載波頻(pin)(pin)率太小，宿遷(qian)西(xi)門子V120變頻(pin)(pin)器(qi)，都可能(neng)引起(qi)電機(ji)和變頻(pin)(pin)器(qi)一起(qi)發熱。

電(dian)機(ji)和變頻(pin)器之間(jian)的連接線(xian)，一般不宜太(tai)長了，不然會(hui)產生(sheng)衰減(jian)和波形畸(ji)變，西門子V120變頻(pin)器哪家好，如(ru)果要(yao)使(shi)(shi)用，也應該使(shi)(shi)用變頻(pin)器，外加電(dian)抗(kang)器來處理。

有些需要(yao)快速剎車(che)的(de)場合，西門子V120變頻器報價，需要(yao)根據制動功率(lv)選(xuan)購(gou)合適的(de)制動電阻(zu)和制動單元等配件。

明泰(tai)(tai)電(dian)(dian)(dian)(dian)(dian)氣（蘇州）有(you)限公司是正泰(tai)(tai)集團在(zai)蘇州地區一家(jia)授(shou)權的經銷(xiao)(xiao)企業，連續十年銷(xiao)(xiao)量居正泰(tai)(tai)營銷(xiao)(xiao)網絡(luo)名，公司主要經營“正泰(tai)(tai)”牌配電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)、控制電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)、終端電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)、電(dian)(dian)(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)、電(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)子、儀器(qi)(qi)(qi)儀表、建筑電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)、高壓電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)及成套設(she)備。

變(bian)頻(pin)器運行的相關(guan)參數(shu)設置：

1.控(kong)制(zhi)(zhi)方式：即速度(du)控(kong)制(zhi)(zhi)、轉距控(kong)制(zhi)(zhi)、PID控(kong)制(zhi)(zhi)或(huo)其他方式。采(cai)取控(kong)制(zhi)(zhi)方式后，一般要(yao)根據控(kong)制(zhi)(zhi)精度(du)，需(xu)要(yao)進行靜態或(huo)動態辨識。

2.運行(xing)頻率(lv)：即電(dian)機(ji)運行(xing)的轉(zhuan)速(su)，電(dian)機(ji)在(zai)低轉(zhuan)速(su)下(xia)(xia)運行(xing)時(shi)(shi)，其散熱性能很(hen)差，電(dian)機(ji)長(chang)時(shi)(shi)間(jian)運行(xing)在(zai)低轉(zhuan)速(su)下(xia)(xia)，會導致(zhi)電(dian)機(ji)燒(shao)毀。而且低速(su)時(shi)(shi)，其電(dian)纜中(zhong)的電(dian)流(liu)也(ye)會增(zeng)大，也(ye)會導致(zhi)電(dian)纜發熱。

變頻器發熱原因

優化使用環境

以往經濟條(tiao)件不(bu)好(hao)，很(hen)多小(xiao)廠都(dou)沒有(you)設計獨立的控(kong)制(zhi)(zhi)室，即使有(you)控(kong)制(zhi)(zhi)室，也沒有(you)給控(kong)制(zhi)(zhi)室安裝空(kong)調(diao)(diao)，現在條(tiao)件好(hao)了，完全可(ke)以把變(bian)(bian)頻(pin)器(qi)等器(qi)件安裝在帶空(kong)調(diao)(diao)的控(kong)制(zhi)(zhi)器(qi)里邊使用，這樣變(bian)(bian)頻(pin)器(qi)的溫(wen)度處于(yu)特佳(jia)狀態，不(bu)容易發熱(re)，也因(yin)為粉塵等減少延長了使用壽命，細算(suan)起來(lai)，實際上是比較(jiao)好(hao)的一種(zhong)投(tou)資(zi)了。
