星三角電壓復位功能：
現在有一(yi)種新(xin)型的星三(san)角時間繼(ji)(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)，具有記憶功能(neng)，有兩個(ge)(ge)線(xian)(xian)圈(quan)(quan)，一(yi)個(ge)(ge)是(shi)吸(xi)zhidao合線(xian)(xian)圈(quan)(quan)，加(jia)上電(dian)(dian)(dian)(dian)(dian)(dian)壓繼(ji)(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)吸(xi)合，但吸(xi)合線(xian)(xian)圈(quan)(quan)斷(duan)電(dian)(dian)(dian)(dian)(dian)(dian)后繼(ji)(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)仍然(ran)保持吸(xi)合狀態(tai)。而(er)要斷(duan)開繼(ji)(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)需要給復(fu)位(wei)線(xian)(xian)圈(quan)(quan)加(jia)上一(yi)個(ge)(ge)電(dian)(dian)(dian)(dian)(dian)(dian)壓，繼(ji)(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)就斷(duan)開了，之后復(fu)位(wei)電(dian)(dian)(dian)(dian)(dian)(dian)壓也(ye)斷(duan)電(dian)(dian)(dian)(dian)(dian)(dian)，這內個(ge)(ge)電(dian)(dian)(dian)(dian)(dian)(dian)壓稱(cheng)為復(fu)位(wei)電(dian)(dian)(dian)(dian)(dian)(dian)容壓。這種斷(duan)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)的好處是(shi)繼(ji)(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)吸(xi)合后線(xian)(xian)圈(quan)(quan)是(shi)不帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)的，這就避(bi)免了線(xian)(xian)圈(quan)(quan)的磁性對觸點信號的干擾。
我(wo)們(men)常見(jian)的(de)星三角(jiao)(jiao)時間繼電器，接線端(duan)(duan)子(zi)(插(cha)腳)分為電源(yuan)端(duan)(duan)子(zi)(插(cha)腳)和觸(chu)點端(duan)(duan)子(zi)(插(cha)腳)。但是(shi)(shi)有的(de)星三角(jiao)(jiao)時間繼電器上面有一組復(fu)位(wei)功(gong)能(neng)端(duan)(duan)子(zi)，這(zhe)個一般很少應用(yong)得到，但是(shi)(shi)這(zhe)個復(fu)位(wei)功(gong)能(neng)在一些應用(yong)中(zhong)還是(shi)(shi)比較實用(yong)與靈活方便的(de)。
這個復位功能(neng)是星三角(jiao)時(shi)(shi)間繼電(dian)(dian)(dian)器接通電(dian)(dian)(dian)源后(hou)，星三角(jiao)時(shi)(shi)間繼電(dian)(dian)(dian)器開始計時(shi)(shi)工作，在此時(shi)(shi)接通3、4復位功能(neng)腳(只能(neng)接無(wu)源開關，嚴禁接入電(dian)(dian)(dian)源),時(shi)(shi)間繼電(dian)(dian)(dian)器延時(shi)(shi)觸點將(jiang)回到初(chu)始位，計時(shi)(shi)數清零(ling)。如果斷(duan)開3、4復位功能(neng)腳，星三角(jiao)時(shi)(shi)間繼電(dian)(dian)(dian)器將(jiang)重新(xin)計時(shi)(shi)。
那么(me)(me)細(xi)心(xin)的朋友可以會發(fa)現一(yi)個問(wen)題(ti)是什么(me)(me)呢(ni)？這(zhe)(zhe)個斷電(dian)(dian)延(yan)時(shi)繼電(dian)(dian)器，只(zhi)有斷開電(dian)(dian)源后(hou)，才能進入計(ji)時(shi)工(gong)作模式，這(zhe)(zhe)個復位又有什么(me)(me)意義呢(ni)?其實這(zhe)(zhe)個斷電(dian)(dian)延(yan)時(shi)繼電(dian)(dian)器的復位功能，是一(yi)個輔(fu)助功能，是一(yi)個擴(kuo)展(zhan)，可以在電(dian)(dian)路中根據(ju)實際控制要求來使用復位功能。
