電(dian)動機保護器(qi)可避(bi)免設備不必要(yao)的停機
傳統(tong)的電(dian)(dian)(dian)(dian)機保(bao)護裝置(zhi)以熔(rong)斷(duan)器(qi)、熱(re)繼電(dian)(dian)(dian)(dian)器(qi) 為(wei)主，熔(rong)斷(duan)器(qi)主要用(yong)于短路保(bao)護，熔(rong)斷(duan)器(qi)電(dian)(dian)(dian)(dian)流(liu)的選擇需考慮電(dian)(dian)(dian)(dian)動(dong)(dong)機的起動(dong)(dong)電(dian)(dian)(dian)(dian)流(liu)，所以單獨使用(yong)熔(rong)斷(duan)器(qi)保(bao)護電(dian)(dian)(dian)(dian)動(dong)(dong)機是(shi)不可取的。熱(re)繼電(dian)(dian)(dian)(dian)器(qi)是(shi)應用(yong)最廣(guang)的電(dian)(dian)(dian)(dian)機過載保(bao)護裝置(zhi)，但熱(re)繼電(dian)(dian)(dian)(dian)器(qi)靈敏度低、誤差大、穩(wen)定(ding)性(xing)差，保(bao)護不可靠。事實(shi)也正(zheng)是(shi)這樣，盡管許多設備安裝了熱(re)繼電(dian)(dian)(dian)(dian)器(qi)，但電(dian)(dian)(dian)(dian)機損壞而影響(xiang)正(zheng)常生(sheng)產的現(xian)象仍普(pu)遍存在。傳統(tong)的保(bao)護裝置(zhi)還(huan)沒有能夠實(shi)現(xian)電(dian)(dian)(dian)(dian)動(dong)(dong)機的機械磨(mo)損監測、定(ding)轉子偏心監測的產品(pin)。
開民電(dian)動機保護器(qi)是對電(dian)動機運(yun)行(xing)過程(cheng)中(zhong)的(de)(de)各(ge)種運(yun)行(xing)信(xin)息(xi)數據(ju)進(jin)行(xing)采集、運(yun)算(suan)(suan)、分析、監控、報警、控制的(de)(de)綜(zong)合性(xing)裝(zhuang)置，可(ke)以通過數據(ju)信(xin)息(xi)通訊實現電(dian)動機運(yun)行(xing)狀況的(de)(de)詳細信(xin)息(xi)在上位機上進(jin)行(xing)實時(shi)監測(ce)，并(bing)經計算(suan)(suan)機數據(ju)處理提供管理信(xin)息(xi)，在設備(bei)可(ke)能產生重(zhong)大故障前，越限報警可(ke)及時(shi)提醒管理人員進(jin)行(xing)處理，避免了不必要的(de)(de)停機而對正常生產造(zao)成影響，最大限度地保證(zheng)設備(bei)運(yun)行(xing)和控制的(de)(de)有(you)效性(xing)。
電動機保(bao)護(hu)器安裝好壞將直接影響到(dao)后期設備的(de)(de)正(zheng)常運(yun)行，因此使用者應(ying)注意對其的(de)(de)安裝，步驟如(ru)下：
1、根(gen)據安裝部位要求方式(shi)和(he)保護功能的需要，合理選擇電動機(ji)保護器型號及其各項保護動作(zuo)參(can)數設置；
2、按(an)產品使用(yong)說明書要求正確安裝(zhuang)，應按(an)各接線端子用(yong)途正確無誤連接，工作電(dian)源(yuan)應接在控制回路前，并(bing)注意標稱電(dian)壓與(yu)實際電(dian)壓相(xiang)符合；
3、電(dian)(dian)動機保(bao)護器(qi)配用(yong)電(dian)(dian)流(liu)變比互感(gan)器(qi)時(shi)，若設備現場或(huo)控制室需電(dian)(dian)流(liu)表顯示時(shi)，最好另配一個電(dian)(dian)流(liu)互感(gan)器(qi)，不(bu)然對配帶(dai)電(dian)(dian)流(liu)表的那(nei)相電(dian)(dian)流(liu)顯示會(hui)有(you)影響；
4、安裝(zhuang)分體式的保護器不要(yao)將(jiang)不同編號的配(pei)套互感(gan)器和顯示部分共同使用；
5、可以按用戶要求改(gai)進，模擬(ni)量(liang)4-20毫安(an)接(jie)口輸出量(liang)應與連接(jie)設(she)備相匹配使用；
6、正(zheng)確接地，低壓系(xi)(xi)統(tong)為TN-C保(bao)(bao)(bao)護系(xi)(xi)統(tong)時，保(bao)(bao)(bao)護器負載側的設備的接地保(bao)(bao)(bao)護線(xian)必須(xu)改為按TT系(xi)(xi)統(tong)的獨立(li)保(bao)(bao)(bao)護接地，中(zhong)性(xing)線(xian)不(bu)得重復接地，不(bu)得作為保(bao)(bao)(bao)護線(xian)。
