現如今，在工業以及農業生產中，電動機所扮演的角色是相當重要的，如果電動機出現問題，將會影響到整個工廠的運行，因此一定要對電動機保護加以重視，目前市場上比較主流的電動機保護裝置有電動機保護器以及熱繼電器兩種，那我們應該怎么選呢？
現在(zai)，在(zai)選擇電(dian)(dian)(dian)動(dong)機(ji)(ji)(ji)(ji)保(bao)護的時候我們一般會選擇電(dian)(dian)(dian)動(dong)機(ji)(ji)(ji)(ji)保(bao)護器，電(dian)(dian)(dian)動(dong)機(ji)(ji)(ji)(ji)保(bao)護器采用(yong)(yong)模塊化設計(ji)構(gou)造(zao)，產品體(ti)積小、結(jie)構(gou)緊湊(cou)、導軌或鏍栓(shuan)安(an)裝，適用(yong)(yong)于各種固定式柜體(ti)和抽屜柜中可直接安(an)裝使用(yong)(yong)，能(neng)夠對三相異(yi)步電(dian)(dian)(dian)動(dong)機(ji)(ji)(ji)(ji)和增(zeng)安(an)電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)進行保(bao)護控制(zhi)，是化工、石油、電(dian)(dian)(dian)力、礦山(shan)、煤炭、治金、市(shi)政、紡(fang)織業等眾多領域(yu)行業中的三相電(dian)(dian)(dian)動(dong)機(ji)(ji)(ji)(ji)保(bao)護理想產品。
熱繼(ji)電(dian)(dian)(dian)器(qi)(qi)的(de)價(jia)格非(fei)常優(you)惠，電(dian)(dian)(dian)動(dong)機(ji)(ji)保(bao)(bao)護(hu)(hu)(hu)器(qi)(qi)的(de)保(bao)(bao)護(hu)(hu)(hu)功能非(fei)常全(quan)(quan)面，但是凡(fan)事都有兩面性，熱繼(ji)電(dian)(dian)(dian)器(qi)(qi)主要是對電(dian)(dian)(dian)動(dong)機(ji)(ji)出現(xian)過(guo)載(zai)時(shi)對其(qi)保(bao)(bao)護(hu)(hu)(hu)器(qi)(qi)，及方式一般(ban)為：易熔合金(jin)式、雙金(jin)屬片(pian)式、熱敏電(dian)(dian)(dian)阻式。都是利(li)用金(jin)屬熱原理進行對電(dian)(dian)(dian)機(ji)(ji)斷(duan)電(dian)(dian)(dian)保(bao)(bao)護(hu)(hu)(hu)，保(bao)(bao)護(hu)(hu)(hu)效(xiao)果一般(ban)。但它的(de)優(you)勢在(zai)于成本(ben)低(di)，體積小，對于交流電(dian)(dian)(dian)動(dong)機(ji)(ji)過(guo)載(zai)的(de)斷(duan)相(xiang)保(bao)(bao)護(hu)(hu)(hu)應用非(fei)常成熟。但隨著目前的(de)發展需求，熱繼(ji)電(dian)(dian)(dian)器(qi)(qi)的(de)功能相(xiang)對較(jiao)少，不(bu)(bu)適(shi)應頻(pin)繁的(de)點(dian)動(dong)操作，也不(bu)(bu)能對短路原因進行電(dian)(dian)(dian)動(dong)機(ji)(ji)保(bao)(bao)護(hu)(hu)(hu)。而電(dian)(dian)(dian)動(dong)機(ji)(ji)保(bao)(bao)護(hu)(hu)(hu)器(qi)(qi)不(bu)(bu)僅可(ke)以(yi)(yi)提供(gong)一組用于故障保(bao)(bao)護(hu)(hu)(hu)使用的(de)獨立觸點(dian)，與熱繼(ji)電(dian)(dian)(dian)器(qi)(qi)相(xiang)比(bi)，其(qi)本(ben)體還有一組電(dian)(dian)(dian)氣上完全(quan)(quan)獨立的(de)常開(kai)觸點(dian)，用于設計報警或其(qi)他電(dian)(dian)(dian)路。并(bing)且可(ke)以(yi)(yi)根(gen)據現(xian)場工作要求，可(ke)以(yi)(yi)定制故障自(zi)動(dong)復(fu)位，時(shi)間可(ke)調，或過(guo)載(zai)立即保(bao)(bao)護(hu)(hu)(hu)等功能。
經過(guo)這些年的不(bu)斷(duan)發展(zhan)，電(dian)(dian)(dian)(dian)動機(ji)保(bao)護(hu)(hu)器(qi)已經由過(guo)去的機(ji)械(xie)式發展(zhan)成電(dian)(dian)(dian)(dian)子式以及智能(neng)型，通(tong)過(guo)電(dian)(dian)(dian)(dian)動機(ji)保(bao)護(hu)(hu)器(qi)可以直觀(guan)的看(kan)到電(dian)(dian)(dian)(dian)壓、電(dian)(dian)(dian)(dian)流(liu)、故(gu)障代(dai)碼等參數，既能(neng)對電(dian)(dian)(dian)(dian)動機(ji)進行保(bao)護(hu)(hu)又能(neng)通(tong)過(guo)參數初步(bu)判斷(duan)故(gu)障。上海碩吉電(dian)(dian)(dian)(dian)器(qi)有限公(gong)司是(shi)(shi)一(yi)家專業的電(dian)(dian)(dian)(dian)動機(ji)保(bao)護(hu)(hu)器(qi)生產廠家，公(gong)司所生產的電(dian)(dian)(dian)(dian)動機(ji)保(bao)護(hu)(hu)器(qi)是(shi)(shi)基于微處理器(qi)技術開(kai)發研制的電(dian)(dian)(dian)(dian)動機(ji)保(bao)護(hu)(hu)和(he)控制裝置，集測(ce)量、保(bao)護(hu)(hu)、控制、聯鎖、通(tong)訊等功能(neng)于一(yi)體，可對三相異(yi)步(bu)電(dian)(dian)(dian)(dian)動機(ji)和(he)增安電(dian)(dian)(dian)(dian)動機(ji)進行保(bao)護(hu)(hu)控制。
