接觸(chu)器(qi)分(fen)為交流(liu)(liu)接觸(chu)器(qi)（電壓(ya)AC）和直流(liu)(liu)接觸(chu)器(qi)（電壓(ya)DC），它(ta)應用于電力、配電與用電場(chang)合。接觸(chu)器(qi)廣義上(shang)是指工業電中(zhong)利用線圈流(liu)(liu)過(guo)電流(liu)(liu)后產生磁場(chang)，使觸(chu)頭(tou)閉合，以達到控制負載的電器(qi)。

在(zai)電工學(xue)上，正(zheng)泰接觸器CJX2廠家，因為(wei)可快速切斷交流與直流主回路和

可頻繁地接(jie)通與大(da)(da)電流控(kong)制（達800A）電路的裝置(zhi)，所以經常運用于電動(dong)機做為控(kong)制對象﹐也(ye)可用作控(kong)制工(gong)廠設備﹑電熱器(qi)﹑工(gong)作母(mu)機和(he)各樣(yang)電力機組等電力負載(zai)，接(jie)觸器(qi)不(bu)僅能接(jie)通和(he)切斷電路，而且還具有低(di)電壓釋放保護(hu)作用。接(jie)觸器(qi)控(kong)制容(rong)量大(da)(da)，適(shi)用于頻繁操(cao)作和(he)遠距離控(kong)制，是(shi)自動(dong)控(kong)制系(xi)統中的重(zhong)要元件之一。

在工(gong)業(ye)電(dian)氣中，接觸器的型號很(hen)多，工(gong)作電(dian)流在5A-1000A的不等，正泰接觸器CJX2供應商，其(qi)用處相當廣泛。

直流接觸器(qi)的選用方式

當接觸器線圈通電(dian)(dian)后，線圈電(dian)(dian)流后產生磁場，使靜鐵心產生電(dian)(dian)磁吸(xi)力吸(xi)引(yin)動鐵心，并帶動觸點(dian)(dian)動作：常(chang)(chang)閉(bi)觸點(dian)(dian)斷(duan)開(kai)，常(chang)(chang)開(kai)觸點(dian)(dian)閉(bi)合，兩者是聯動的。當線圈斷(duan)電(dian)(dian)時，電(dian)(dian)磁吸(xi)力消失，銜鐵在釋放彈簧的作用下釋放，使觸點(dian)(dian)復原：常(chang)(chang)開(kai)觸點(dian)(dian)斷(duan)開(kai)，常(chang)(chang)閉(bi)觸點(dian)(dian)閉(bi)合

混合式直流接觸器

直(zhi)流電(dian)流與交流電(dian)流相比較(jiao)，不(bu)存在周期性的電(dian)流數值(zhi)過零點，因此，傳(chuan)統(tong)接觸(chu)器開斷(duan)電(dian)路(lu)(lu)時(shi)，上海正(zheng)泰接觸(chu)器CJX2，觸(chu)頭(tou)之間產生的電(dian)弧較(jiao)為強烈，燃弧時(shi)間也比較(jiao)長，以便充分(fen)釋放電(dian)路(lu)(lu)中剩余的能量。電(dian)弧的燃燒產生高溫(wen)和強光，對觸(chu)頭(tou)表面(mian)有(you)嚴重的燒蝕作用，觸(chu)頭(tou)材料在多次開斷(duan)之后逐漸流失，觸(chu)頭(tou)電(dian)磨損嚴重時(shi)，導(dao)致直(zhi)流接觸(chu)器報廢(fei)，不(bu)能開斷(duan)電(dian)路(lu)(lu)。
