在污水(shui)處理設備(bei)中電動(dong)機的馬達(da)保護器有哪些作(zuo)用？我想大家一定不(bu)是特別了解，依斯倍作(zuo)為專業(ye)從事工業(ye)廢水(shui)處理的水(shui)處理環保企業(ye)，為大家提供環保行業(ye)設備(bei)常見(jian)工藝技術問(wen)題知識解答，今天(tian)我(wo)們(men)就(jiu)這個專業問題給大家(jia)帶(dai)來解答(da)。

在廢水處理項目利(li)民，設計系統中(zhong)用到了(le)很多馬(ma)達保(bao)(bao)護器(qi)，要確定馬(ma)達保(bao)(bao)護器(qi)的(de)(de)型號，首先得了(le)解電動機的(de)(de)型號規格、功能特(te)性、防護形式(shi)、額(e)定電壓、額(e)定電流、額(e)定功率、電源頻率以及絕緣等級等。作用是給電動機全面的(de)(de)保(bao)(bao)護，在電動機出現(xian)超時啟動、過(guo)流、欠(qian)流、斷相(xiang)、堵轉(zhuan)、短路、過(guo)壓、欠(qian)壓、漏(lou)電（接地）、三相(xiang)不平衡、過(guo)熱、軸(zhou)承磨損、定轉(zhuan)子偏(pian)心、外部(bu)故障、來電自啟動、反時限時，予以報警或保(bao)(bao)護的(de)(de)裝置。

馬(ma)達電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)因(yin)(yin)(yin)電(dian)(dian)(dian)(dian)(dian)(dian)性(xing)原(yuan)因(yin)(yin)(yin)出(chu)(chu)現(xian)過(guo)負荷、缺相(xiang)(xiang)(xiang)、層(ceng)間短路及線(xian)間短路、線(xian)圈的(de)(de)(de)(de)(de)(de)接地漏電(dian)(dian)(dian)(dian)(dian)(dian)、瞬(shun)間過(guo)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)的(de)(de)(de)(de)(de)(de)流(liu)入等造(zao)成損(sun)(sun)壞，或者是(shi)(shi)由于(yu)(yu)機(ji)(ji)械原(yuan)因(yin)(yin)(yin)，如(ru)堵轉、電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)轉動體遇到固體時，因(yin)(yin)(yin)軸承磨損(sun)(sun)或潤滑油(you)缺乏(fa)出(chu)(chu)現(xian)熱傳導(dao)現(xian)象，損(sun)(sun)壞電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)。由于(yu)(yu)非正常運行或停止或損(sun)(sun)壞，會造(zao)成生(sheng)產損(sun)(sun)失或停止時間內產生(sheng)的(de)(de)(de)(de)(de)(de)人力損(sun)(sun)失無(wu)法(fa)與電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)本(ben)身更換的(de)(de)(de)(de)(de)(de)費用相(xiang)(xiang)(xiang)提并論(lun)，其(qi)損(sun)(sun)失巨(ju)大，那么我們就需要(yao)對電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)進行有效(xiao)的(de)(de)(de)(de)(de)(de)保(bao)護(hu)(hu)，以便保(bao)證生(sheng)產的(de)(de)(de)(de)(de)(de)正常運行。對于(yu)(yu)因(yin)(yin)(yin)電(dian)(dian)(dian)(dian)(dian)(dian)性(xing)原(yuan)因(yin)(yin)(yin)出(chu)(chu)現(xian)的(de)(de)(de)(de)(de)(de)故障，無(wu)論(lun)是(shi)(shi)過(guo)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)還是(shi)(shi)過(guo)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)，其(qi)主要(yao)是(shi)(shi)因(yin)(yin)(yin)為電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)瞬(shun)間增大，超過(guo)了電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)的(de)(de)(de)(de)(de)(de)負載電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)值而造(zao)成損(sun)(sun)壞。馬(ma)達保(bao)護(hu)(hu)器根據這一(yi)原(yuan)理，通過(guo)監測(ce)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)的(de)(de)(de)(de)(de)(de)兩相(xiang)(xiang)(xiang)（三相(xiang)(xiang)(xiang)）線(xian)路的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)值變化(hua)(hua)，進行電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)的(de)(de)(de)(de)(de)(de)保(bao)護(hu)(hu)，對于(yu)(yu)過(guo)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)、低電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)，是(shi)(shi)通過(guo)檢測(ce)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)相(xiang)(xiang)(xiang)間的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)變化(hua)(hua)，進行電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)的(de)(de)(de)(de)(de)(de)保(bao)護(hu)(hu)，防止出(chu)(chu)現(xian)問題。依斯倍追(zhui)求卓越的(de)(de)(de)(de)(de)(de)質量，讓使用壽命高于(yu)(yu)行業平均水平，為客戶提供高效(xiao)穩定的(de)(de)(de)(de)(de)(de)系統。
