可程式恒溫恒濕箱壓縮機的電氣知識講解

隨著可(ke)程(cheng)式(shi)恒溫恒濕(shi)箱的(de)普及，許多(duo)人(ren)在使用過(guo)程(cheng)中可(ke)能也有越(yue)來越(yue)多(duo)不同的(de)疑(yi)問，今(jin)天小編就(jiu)來跟大家講(jiang)解一下(xia)可(ke)程(cheng)式(shi)恒溫恒濕(shi)箱壓(ya)縮(suo)機的(de)電氣知(zhi)識。

可程式恒溫恒濕箱壓縮機它的電氣部分主要分為“一次回路”和“二次回路”。“一次回(hui)路(lu)”是(shi)以一次設(she)備(bei)(bei)(bei)相互連(lian)接構(gou)成(cheng)發(fa)電(dian)(dian)(dian)(dian)、輸(shu)電(dian)(dian)(dian)(dian)、配電(dian)(dian)(dian)(dian)及(ji)其他生產(chan)的電(dian)(dian)(dian)(dian)氣(qi)回(hui)路(lu)。“一次設(she)備(bei)(bei)(bei)”指發(fa)電(dian)(dian)(dian)(dian)、輸(shu)電(dian)(dian)(dian)(dian)、配電(dian)(dian)(dian)(dian)的主系統(tong)上使用的電(dian)(dian)(dian)(dian)氣(qi)設(she)備(bei)(bei)(bei)。“二次回(hui)路(lu)”是(shi)以二次設(she)備(bei)(bei)(bei)連(lian)接，形成(cheng)對一次設(she)備(bei)(bei)(bei)進行監(jian)督、調節、控制及(ji)保(bao)護(hu)的電(dian)(dian)(dian)(dian)氣(qi)回(hui)路(lu)。“二次設(she)備(bei)(bei)(bei)”指對“一次設(she)備(bei)(bei)(bei)”進行監(jian)察、控制、保(bao)護(hu)和測量的設(she)備(bei)(bei)(bei)，如操(cao)作開(kai)關、自動控制設(she)備(bei)(bei)(bei)、供電(dian)(dian)(dian)(dian)裝(zhuang)置及(ji)測量儀表(biao)繼電(dian)(dian)(dian)(dian)器等。

可程式恒溫恒濕箱壓(ya)(ya)縮機按照電(dian)(dian)源電(dian)(dian)壓(ya)(ya)和啟動(dong)(dong)(dong)(dong)(dong)方式的(de)(de)不(bu)同，其“一(yi)次回路”構成(cheng)(cheng)及(ji)組成(cheng)(cheng)原(yuan)件也不(bu)同。一(yi)般(ban)低(di)(di)壓(ya)(ya)為380V供電(dian)(dian)，低(di)(di)壓(ya)(ya)大功率的(de)(de)電(dian)(dian)機啟動(dong)(dong)(dong)(dong)(dong)電(dian)(dian)流(liu)較大，其直接啟動(dong)(dong)(dong)(dong)(dong)時(shi)啟動(dong)(dong)(dong)(dong)(dong)電(dian)(dian)流(liu)為額定電(dian)(dian)流(liu)的(de)(de)5~7倍。因此為了(le)防止電(dian)(dian)壓(ya)(ya)電(dian)(dian)流(liu)的(de)(de)瞬間變化，及(ji)峰值(zhi)電(dian)(dian)流(liu)形成(cheng)(cheng)對電(dian)(dian)網的(de)(de)沖擊，造成(cheng)(cheng)電(dian)(dian)網過負(fu)荷，造成(cheng)(cheng)電(dian)(dian)壓(ya)(ya)不(bu)正常變化，影響其他設備(bei)運行。故一(yi)般(ban)采取降壓(ya)(ya)啟動(dong)(dong)(dong)(dong)(dong)方式，包括(kuo)星(xing)-三角、軟(ruan)啟動(dong)(dong)(dong)(dong)(dong)及(ji)變頻啟動(dong)(dong)(dong)(dong)(dong)。
