山武AZBIL繼電器選用技巧

繼(ji)(ji)電(dian)器(qi)(qi)線(xian)圈在(zai)電(dian)路(lu)中用一(yi)個(ge)長(chang)方(fang)(fang)(fang)框(kuang)符(fu)(fu)號表示(shi)(shi)，如果(guo)繼(ji)(ji)電(dian)器(qi)(qi)有兩個(ge)線(xian)圈，就畫(hua)兩個(ge)并列(lie)的(de)長(chang)方(fang)(fang)(fang)框(kuang)。同時在(zai)長(chang)方(fang)(fang)(fang)框(kuang)內或(huo)長(chang)方(fang)(fang)(fang)框(kuang)旁標(biao)上繼(ji)(ji)電(dian)器(qi)(qi)的(de)文字符(fu)(fu)號“J"。繼(ji)(ji)電(dian)器(qi)(qi)的(de)觸(chu)(chu)(chu)點有兩種表示(shi)(shi)方(fang)(fang)(fang)法：一(yi)種是把(ba)它們直(zhi)接畫(hua)在(zai)長(chang)方(fang)(fang)(fang)框(kuang)一(yi)側，這種表示(shi)(shi)法較為(wei)直(zhi)觀。另一(yi)種是按照電(dian)路(lu)連接的(de)需要，把(ba)各(ge)個(ge)觸(chu)(chu)(chu)點分別(bie)畫(hua)到各(ge)自的(de)控制(zhi)電(dian)路(lu)中，通常在(zai)同一(yi)繼(ji)(ji)電(dian)器(qi)(qi)的(de)觸(chu)(chu)(chu)點與線(xian)圈旁分別(bie)標(biao)注(zhu)上相同的(de)文字符(fu)(fu)號，并將觸(chu)(chu)(chu)點組編上號碼(ma)，以示(shi)(shi)區別(bie)。

是指繼電(dian)(dian)器能夠產生(sheng)吸合動作的電(dian)(dian)流(liu)。在正常使用時，給定的電(dian)(dian)流(liu)必(bi)須略大于吸合電(dian)(dian)流(liu)，這(zhe)樣繼電(dian)(dian)器才能穩(wen)定地工作。而(er)對(dui)于線(xian)圈(quan)所加的工作電(dian)(dian)壓，一般不要超過額定工作電(dian)(dian)壓的1.5倍(bei)，否則會產生(sheng)較大的電(dian)(dian)流(liu)而(er)把線(xian)圈(quan)燒(shao)毀。

繼(ji)電(dian)(dian)器動(dong)作(zuo)(zuo)時(shi)(shi)所需電(dian)(dian)壓(ya)(ya)(ya)值。觸(chu)點(dian)(dian)接(jie)(jie)觸(chu)電(dian)(dian)阻(zu)。觸(chu)電(dian)(dian)閉合(he)時(shi)(shi)，兩(liang)觸(chu)頭之(zhi)間的電(dian)(dian)阻(zu)值。 機械壽(shou)命。機械部分在不損(sun)壞的情況下(xia)，繼(ji)電(dian)(dian)器反復開關動(dong)作(zuo)(zuo)次(ci)(ci)數(shu)。 觸(chu)點(dian)(dian)接(jie)(jie)觸(chu)電(dian)(dian)壓(ya)(ya)(ya)。觸(chu)電(dian)(dian)閉合(he)時(shi)(shi)，觸(chu)電(dian)(dian)回(hui)路中(zhong)施(shi)(shi)加(jia)(jia)一定(ding)(ding)(ding)負(fu)(fu)載(zai)電(dian)(dian)流，觸(chu)點(dian)(dian)間電(dian)(dian)壓(ya)(ya)(ya)值。電(dian)(dian)壽(shou)命。繼(ji)電(dian)(dian)器驅動(dong)線圈兩(liang)端施(shi)(shi)加(jia)(jia)額定(ding)(ding)(ding)電(dian)(dian)壓(ya)(ya)(ya)，觸(chu)點(dian)(dian)回(hui)路中(zhong)施(shi)(shi)加(jia)(jia)額定(ding)(ding)(ding)阻(zu)性負(fu)(fu)載(zai)時(shi)(shi)，每小時(shi)(shi)循環(huan)小于(yu)300次(ci)(ci)、占空比1∶4條(tiao)件下(xia)，繼(ji)電(dian)(dian)器的可靠(kao)動(dong)作(zuo)(zuo)次(ci)(ci)數(shu)。過負(fu)(fu)荷能力。繼(ji)電(dian)(dian)器驅動(dong)線圈兩(liang)端施(shi)(shi)加(jia)(jia)額定(ding)(ding)(ding)電(dian)(dian)壓(ya)(ya)(ya)，觸(chu)點(dian)(dian)回(hui)路中(zhong)施(shi)(shi)加(jia)(jia)1．5倍額定(ding)(ding)(ding)負(fu)(fu)載(zai)時(shi)(shi)，動(dong)作(zuo)(zuo)頻率（10±1）次(ci)(ci)/分條(tiao)件下(xia)，繼(ji)電(dian)(dian)器可靠(kao)動(dong)作(zuo)(zuo)次(ci)(ci)數(shu)

釋(shi)放電(dian)(dian)(dian)流(liu)(liu)(liu)：是指繼(ji)電(dian)(dian)(dian)器(qi)產(chan)生釋(shi)放動(dong)作的(de)(de)電(dian)(dian)(dian)流(liu)(liu)(liu)。當繼(ji)電(dian)(dian)(dian)器(qi)吸(xi)合(he)狀態的(de)(de)電(dian)(dian)(dian)流(liu)(liu)(liu)減小(xiao)(xiao)到(dao)定程度時，繼(ji)電(dian)(dian)(dian)器(qi)就會(hui)恢復到(dao)未通電(dian)(dian)(dian)的(de)(de)釋(shi)放狀態，這時的(de)(de)電(dian)(dian)(dian)流(liu)(liu)(liu)遠遠小(xiao)(xiao)于吸(xi)合(he)電(dian)(dian)(dian)流(liu)(liu)(liu)。

觸點(dian)切換電(dian)壓和(he)電(dian)流(liu)(liu)：是指繼電(dian)器(qi)允許加載的電(dian)壓和(he)電(dian)流(liu)(liu)。它決定了繼電(dian)器(qi)能控制電(dian)壓和(he)電(dian)流(liu)(liu)的大小，使用時不能超過此值，否則很容易損壞(huai)繼電(dian)器(qi)的觸點(dian)。
