一、熔斷器式隔離開關是什么意思
隔離開關的主要作(zuo)用是(shi)斷(duan)(duan)開小電流(liu),改變運(yun)行方(fang)式,它有多種(zhong)類型,熔(rong)斷(duan)(duan)器式隔(ge)離開關就(jiu)是(shi)其(qi)中一種(zhong),那么(me)什么(me)是(shi)熔(rong)斷(duan)(duan)器式隔(ge)離開關呢?
熔(rong)斷(duan)(duan)器(qi)式(shi)隔離開關(guan)(guan)就是將(jiang)傳統(tong)(tong)的(de)熔(rong)斷(duan)(duan)器(qi)、隔離器(qi)和開關(guan)(guan)結合為一(yi)體(ti)(ti)的(de)熔(rong)斷(duan)(duan)器(qi)組合電(dian)(dian)(dian)器(qi),通常(chang)是動觸頭由熔(rong)斷(duan)(duan)體(ti)(ti)或帶有(you)熔(rong)斷(duan)(duan)體(ti)(ti)的(de)載熔(rong)件組成(cheng)的(de)隔離開關(guan)(guan),這種隔離開關(guan)(guan)不僅可(ke)(ke)帶負荷操作(zuo),而且限流特性(xing)明(ming)顯,選擇特性(xing)好(hao),可(ke)(ke)以實現線路的(de)保(bao)護(hu),可(ke)(ke)廣泛應用(yong)于(yu)低壓配電(dian)(dian)(dian)系(xi)統(tong)(tong)、高低壓配電(dian)(dian)(dian)系(xi)統(tong)(tong)和控制系(xi)統(tong)(tong)以及用(yong)電(dian)(dian)(dian)設(she)備(bei)中,作(zuo)為短路和過電(dian)(dian)(dian)流的(de)保(bao)護(hu)器(qi)使(shi)用(yong)。
二、熔斷器式隔離開關好用嗎
熔(rong)斷器式(shi)隔離開關(guan)是一種(zhong)比(bi)較好用的隔離開關(guan),使用熔(rong)斷器式(shi)隔離開關(guan)進行線(xian)路保(bao)護不僅(jin)具有熔(rong)斷器的特點,還有以下(xia)優點:
1、熔斷(duan)(duan)器(qi)的時間-電流(liu)(liu)特(te)(te)性(xing)(xing)由(you)熔體(ti)的性(xing)(xing)能決(jue)定,熔斷(duan)(duan)器(qi)的時間一電流(liu)(liu)特(te)(te)性(xing)(xing)曲線(xian)(xian)更接(jie)近被保(bao)護(hu)回路的熱承(cheng)受能力特(te)(te)性(xing)(xing)曲線(xian)(xian),具有較好的過電流(liu)(liu)保(bao)護(hu)效(xiao)果。
2、熔斷器式隔離開關可進行額定負(fu)荷下(xia)的開合操作(zuo)。
3、雖然熔(rong)斷(duan)器(qi)的(de)熔(rong)體(ti)只具有一(yi)次開斷(duan)功能,但采用(yong)熔(rong)斷(duan)器(qi)式隔離開關可更換規格相同的(de)熔(rong)體(ti),再(zai)次投入(ru)運行非常(chang)簡便。
4、熔(rong)斷器式隔離開關在低壓配電網絡(luo)中(zhong)可實現遠距離監測(ce)功能。
