plc控制柜里的接(jie)觸器分為交流(liu)(liu)接(jie)觸器(電(dian)(dian)壓(ya)AC)和直(zhi)流(liu)(liu)接(jie)觸器(電(dian)(dian)壓(ya)DC),它應(ying)用于(yu)電(dian)(dian)力、配電(dian)(dian)與用電(dian)(dian)場(chang)合。接(jie)觸器廣義上是(shi)指工業(ye)電(dian)(dian)中利用線圈流(liu)(liu)過電(dian)(dian)流(liu)(liu)產(chan)生磁場(chang),使(shi)觸頭(tou)閉合,以達到控制負載(zai)的電(dian)(dian)器。
在電(dian)工(gong)學上,因為可(ke)快速(su)切斷交流與直流主回路和可(ke)頻繁地接通與關斷大電(dian)流控(kong)(kong)制(zhi)(zhi)(達800A)電(dian)路的(de)裝置(zhi),所以經常運用(yong)于(yu)電(dian)動機(ji)做為控(kong)(kong)制(zhi)(zhi)對象﹐也可(ke)用(yong)作(zuo)控(kong)(kong)制(zhi)(zhi)工(gong)廠設備﹑電(dian)熱(re)器﹑工(gong)作(zuo)母機(ji)和各樣電(dian)力(li)機(ji)組等電(dian)力(li)負載,接觸器不僅能接通和切斷電(dian)路,而且還具有(you)低電(dian)壓釋放保護(hu)作(zuo)用(yong)。接觸器控(kong)(kong)制(zhi)(zhi)容(rong)量大,適(shi)用(yong)于(yu)頻繁操(cao)作(zuo)和遠距離(li)控(kong)(kong)制(zhi)(zhi),是自動控(kong)(kong)制(zhi)(zhi)系統中的(de)重要元件之一。
大連plc控制柜接(jie)(jie)觸(chu)(chu)(chu)(chu)器(qi)(qi)(qi)首要作用是用來接(jie)(jie)通或斷開(kai)主電(dian)(dian)(dian)路(lu)的。主電(dian)(dian)(dian)路(lu)是指一(yi)個電(dian)(dian)(dian)路(lu)工作與否是由該電(dian)(dian)(dian)路(lu)是不是接(jie)(jie)通為標志。主電(dian)(dian)(dian)路(lu)概念與控制電(dian)(dian)(dian)路(lu)相(xiang)對應。一(yi)般(ban)(ban)主電(dian)(dian)(dian)路(lu)通過的電(dian)(dian)(dian)流比控制電(dian)(dian)(dian)路(lu)大(da)。容量大(da)的接(jie)(jie)觸(chu)(chu)(chu)(chu)器(qi)(qi)(qi)一(yi)般(ban)(ban)都帶有(you)滅弧裝置。接(jie)(jie)觸(chu)(chu)(chu)(chu)器(qi)(qi)(qi)的觸(chu)(chu)(chu)(chu)頭(tou)(tou)容量小的也有(you)9A;接(jie)(jie)觸(chu)(chu)(chu)(chu)器(qi)(qi)(qi)的觸(chu)(chu)(chu)(chu)頭(tou)(tou)一(yi)般(ban)(ban)有(you)三對主觸(chu)(chu)(chu)(chu)頭(tou)(tou)(主觸(chu)(chu)(chu)(chu)頭(tou)(tou)都是常開(kai)觸(chu)(chu)(chu)(chu)頭(tou)(tou))另外還有(you)幾(ji)對輔佐觸(chu)(chu)(chu)(chu)頭(tou)(tou)。接(jie)(jie)觸(chu)(chu)(chu)(chu)器(qi)(qi)(qi)不成(cheng)對設置,接(jie)(jie)觸(chu)(chu)(chu)(chu)器(qi)(qi)(qi)一(yi)般(ban)(ban)沒有(you)附加功用。
大連(lian)(lian)plc控制柜接(jie)(jie)觸(chu)器(qi)用來接(jie)(jie)通或斷(duan)開功(gong)率(lv)較大的(de)(de)負載,用在(功(gong)率(lv))主電路中,主觸(chu)頭(tou)可以(yi)帶有連(lian)(lian)鎖接(jie)(jie)點以(yi)表明(ming)主觸(chu)頭(tou)的(de)(de)開閉(bi)情況。如(ru)可以(yi)用繼電器(qi)的(de)(de)觸(chu)點去接(jie)(jie)通或斷(duan)開接(jie)(jie)觸(chu)器(qi)的(de)(de)線(xian)圈(quan)。一般繼電器(qi)都有較多(duo)的(de)(de)開閉(bi)觸(chu)點,當(dang)然繼電器(qi)通過恰(qia)當(dang)的(de)(de)接(jie)(jie)法(fa)還(huan)可以(yi)完結某些格外功(gong)用,如(ru)邏輯(ji)運算等(deng)。
