配電柜廠家跟你聊一聊配電箱隔離(li)開(kai)關(circuit-breaker)的保護器

配電(dian)柜廠家_低壓配電(dian)箱隔離開關(guan)(circuit-breaker)的保護器有什么？

1.電(dian)磁脫扣器

當穿過的(de)電(dian)(dian)(dian)(dian)(dian)流量(Electron flow)在整定值(zhi)之內時，電(dian)(dian)(dian)(dian)(dian)磁(ci)脫扣(kou)器(qi)電(dian)(dian)(dian)(dian)(dian)磁(ci)線圈(winding)所發病的(de)吸附(fu)力(li)不能吸動(dong)銜(xián)鐵。當發病短路(lu)(lu)(lu)故障(電(dian)(dian)(dian)(dian)(dian)流量沒經(jing)大(da)功率電(dian)(dian)(dian)(dian)(dian)器(qi)、立(li)即連開關(guan)電(dian)(dian)(dian)(dian)(dian)源兩方面(mian))問題(ti)時，短路(lu)(lu)(lu)容量超出整定值(zhi)，強磁(ci)場(界定:傳(chuan)送商(shang)品間磁(ci)力(li)功效(xiao)的(de)場)的(de)吸附(fu)力(li)擊敗繃簧(huang)的(de)抗拉力(li)帶動(dong)流線圈，頂開勾子(zi)，使電(dian)(dian)(dian)(dian)(dian)源開關(guan)跳電(dian)(dian)(dian)(dian)(dian)（zhá)。電(dian)(dian)(dian)(dian)(dian)磁(ci)脫扣(kou)器(qi)具有斷路(lu)(lu)(lu)器(qi)（Fuse)的(de)實(shi)際(ji)效(xiao)果。

2.過壓脫扣器

過壓脫(tuo)扣器(qi)的工(gong)(gong)(gong)作(zuo)系(xi)統進程與電(dian)磁(ci)(ci)脫(tuo)扣器(qi)的工(gong)(gong)(gong)作(zuo)系(xi)統進程正好相反(fan)。當開(kai)關(guan)電(dian)源(yuan)工(gong)(gong)(gong)作(zuo)電(dian)壓在(zai)額定(ding)電(dian)流(rated value)時(shi)，過壓脫(tuo)扣器(qi)電(dian)磁(ci)(ci)線(xian)圈(winding)發病的磁(ci)(ci)力(li)得以(yi)將銜(xian)(xián)鐵吸合(he)，使電(dian)源(yuan)開(kai)關(guan)重合(he)閘（zhá)情(qing)況。當開(kai)關(guan)電(dian)源(yuan)工(gong)(gong)(gong)作(zuo)電(dian)壓降低(descend)到小于整定(ding)值或降至零時(shi)，在(zai)繃簧實(shi)際效(xiao)果下銜(xian)(xián)鐵被開(kai)釋，頂開(kai)勾子而(er)斷開(kai)（劃開(kai)；斷開(kai))開(kai)關(guan)電(dian)源(yuan)。

3.熱脫扣器

熱脫扣器的實(shi)際效果和基本(ben)概念(nian)(principle)與熱繼電器（relay)同(tong)樣。

4.分勵脫扣器

分勵脫扣器用以遠(yuan)途(tu)間距實際操作。在一(yi)切正常工作中，其電(dian)(dian)磁(ci)線圈(winding)是(shi)關閉電(dian)(dian)源(yuan)的。在必須遠(yuan)間距實際操作時，使(shi)電(dian)(dian)磁(ci)線圈接電(dian)(dian)源(yuan)，電(dian)(dian)磁(ci)鐵推動機械(xie)設備(bei)(Mechanics)機構姿勢(shi)，使(shi)電(dian)(dian)源(yuan)開關跳(tiao)電(dian)(dian)（zhá)。

5.小復式脫扣器

電(dian)源開關另外具備電(dian)磁脫扣(kou)器和熱脫扣(kou)器時，稱之為有(you)小(xiao)復(fu)式脫扣(kou)器。

什(shen)么叫主(zhu)電路(lu)?

答： 機械設備(equipment)中一條用于傳送(song)電磁能的(de)電路上全部的(de)導電性構件。

什么(me)叫輔助電路?

答：機械設(she)備(equipment)中(zhong)（除(chu)主電(dian)(dian)路之外）用以操縱（control)、測量、數(shu)據信號和調(diao)整，數(shu)據信息（data)解決等(deng)電(dian)(dian)路上全部的(de)導(dao)電(dian)(dian)性構件。

什(shen)么叫(jiao)防(fang)水(shui)等級(Grade)?

答：避免(mian)身體貼近感應起(qi)電一(yi)部分或碰觸健身運(yun)動一(yi)部分的機殼、擋板(ban)及其(qi)避免(mian)固態物塊入(ru)侵機器設備(equipment)應具有(you)的維護水平。

工作接地的含意？

答：工(gong)作接地(di)就是(shi)指(zhi)供(gong)電(dian)(dian)系統中一(yi)些機器(qi)設備(equipment)因運(yun)作的必須，立即或根據消弧線圈(winding)、電(dian)(dian)抗器(qi)、電(dian)(dian)阻(zu)器(qi)等與地(di)面金屬材料聯(lian)接，稱之為工(gong)作接地(di)
