星三角電壓復位功能：

現(xian)在有一(yi)種新型的(de)星三角時間繼(ji)(ji)(ji)電(dian)(dian)(dian)(dian)器，具有記憶功能(neng)，有兩個線(xian)圈，一(yi)個是(shi)吸zhidao合(he)線(xian)圈，加上電(dian)(dian)(dian)(dian)壓(ya)(ya)繼(ji)(ji)(ji)電(dian)(dian)(dian)(dian)器吸合(he)，但(dan)吸合(he)線(xian)圈斷電(dian)(dian)(dian)(dian)后(hou)繼(ji)(ji)(ji)電(dian)(dian)(dian)(dian)器仍然保(bao)持吸合(he)狀態。而要斷開繼(ji)(ji)(ji)電(dian)(dian)(dian)(dian)器需要給復位線(xian)圈加上一(yi)個電(dian)(dian)(dian)(dian)壓(ya)(ya)，繼(ji)(ji)(ji)電(dian)(dian)(dian)(dian)器就(jiu)斷開了，之后(hou)復位電(dian)(dian)(dian)(dian)壓(ya)(ya)也(ye)斷電(dian)(dian)(dian)(dian)，這內(nei)個電(dian)(dian)(dian)(dian)壓(ya)(ya)稱(cheng)為復位電(dian)(dian)(dian)(dian)容壓(ya)(ya)。這種斷電(dian)(dian)(dian)(dian)器的(de)好處是(shi)繼(ji)(ji)(ji)電(dian)(dian)(dian)(dian)器吸合(he)后(hou)線(xian)圈是(shi)不帶電(dian)(dian)(dian)(dian)的(de)，這就(jiu)避(bi)免了線(xian)圈的(de)磁性(xing)對(dui)觸點信(xin)號的(de)干擾。

我們常(chang)見的星三角時間(jian)繼(ji)電(dian)器，接線端(duan)(duan)子(zi)(zi)(插(cha)腳(jiao))分為電(dian)源(yuan)端(duan)(duan)子(zi)(zi)(插(cha)腳(jiao))和觸點端(duan)(duan)子(zi)(zi)(插(cha)腳(jiao))。但是(shi)有(you)的星三角時間(jian)繼(ji)電(dian)器上面(mian)有(you)一組復(fu)位(wei)功能端(duan)(duan)子(zi)(zi)，這(zhe)個(ge)一般很少應(ying)用(yong)得到，但是(shi)這(zhe)個(ge)復(fu)位(wei)功能在一些(xie)應(ying)用(yong)中還是(shi)比較實用(yong)與靈活方便的。

這(zhe)個復位功(gong)(gong)能(neng)是星(xing)(xing)三角(jiao)(jiao)時(shi)間(jian)繼(ji)(ji)電(dian)器接(jie)通(tong)電(dian)源后，星(xing)(xing)三角(jiao)(jiao)時(shi)間(jian)繼(ji)(ji)電(dian)器開(kai)始計時(shi)工(gong)作，在(zai)此時(shi)接(jie)通(tong)3、4復位功(gong)(gong)能(neng)腳(只能(neng)接(jie)無(wu)源開(kai)關(guan)，嚴(yan)禁接(jie)入(ru)電(dian)源),時(shi)間(jian)繼(ji)(ji)電(dian)器延時(shi)觸點(dian)將回到初始位，計時(shi)數清零。如果斷(duan)開(kai)3、4復位功(gong)(gong)能(neng)腳，星(xing)(xing)三角(jiao)(jiao)時(shi)間(jian)繼(ji)(ji)電(dian)器將重新(xin)計時(shi)。

那么(me)細心(xin)的(de)朋友可以會(hui)發現一(yi)(yi)個(ge)(ge)問(wen)題是什么(me)呢(ni)？這個(ge)(ge)斷(duan)(duan)電(dian)(dian)延(yan)時(shi)(shi)繼電(dian)(dian)器，只有斷(duan)(duan)開電(dian)(dian)源后，才能(neng)進入計時(shi)(shi)工作(zuo)模式，這個(ge)(ge)復位又(you)有什么(me)意義呢(ni)?其(qi)實這個(ge)(ge)斷(duan)(duan)電(dian)(dian)延(yan)時(shi)(shi)繼電(dian)(dian)器的(de)復位功(gong)能(neng)，是一(yi)(yi)個(ge)(ge)輔助功(gong)能(neng)，是一(yi)(yi)個(ge)(ge)擴展，可以在電(dian)(dian)路(lu)中根據實際(ji)控(kong)制要(yao)求(qiu)來使用復位功(gong)能(neng)。
