電氣控制線路安裝接線圖,是為了安裝電氣設(shè)備和電器元件進(jìn)行配線或檢修電器故障服務(wù)的。在圖中可顯示出電氣設(shè)備中各元件的空間位置和接線情況,可在安裝或檢修時(shí)對照原理圖使用。它是根據(jù)電器位置布置依合理經(jīng)濟(jì)等原則安排的,它表示機(jī)床電氣設(shè)備各個(gè)單元之間的接線關(guān)系,并標(biāo)注出外部接線所需的數(shù)據(jù)。根據(jù)機(jī)床設(shè)備的接線圖就可以進(jìn)行機(jī)床電氣設(shè)備的安裝接線。對某些較為復(fù)雜的電氣設(shè)備,電氣安裝板上元件較多時(shí),還可畫出安裝板的接線圖。對于簡單設(shè)備,僅畫出接線圖就可以了。實(shí)際工作中,接線圖常與電氣原理圖結(jié)合起來使用。熔斷器的結(jié)構(gòu)一般分成熔體座和熔體等部分。熔斷器是串聯(lián)連接在被保護(hù)電路中的,當(dāng)電路電流超過一定值時(shí),熔體因發(fā)熱而熔斷,使電路被切斷,從而起到保護(hù)作用。熔體的熱量與通過熔體電流的平方及持續(xù)通電時(shí)間成正比,當(dāng)電路短路時(shí),電流很大,熔體急劇升溫,立即熔斷,當(dāng)電路中電流值等于熔體額定電流時(shí),熔體不會(huì)熔斷。所以熔斷器可用于短路保護(hù)。由于熔體在用電設(shè)備過載時(shí)所通過的過載電流能積累熱量,當(dāng)用電設(shè)備連續(xù)過載一定時(shí)間后熔體積累的熱量也能使其熔斷,所以熔斷器也可作過載保護(hù)。
