(2)額定電流
斷路器的額定電流與過電流脫扣器的額定電流應(yīng)大于線路計(jì)算負(fù)荷電流。當(dāng)按線路的計(jì)算電流選擇時(shí),應(yīng)能滿足下式:
(4-10-6)
式中 ——低壓斷路器的額定電流,A;
——線路的計(jì)算電流或?qū)嶋H電流,A。
如果環(huán)境溫度低于+40℃,則電器產(chǎn)品溫度每低1℃,允許電流比額定電流值增加0.5%。但增加總數(shù)不得超過20%。
10.5 低壓斷路器
斷路器的保護(hù)定值
(1)長(zhǎng)延時(shí)脫扣器的電流整定值,動(dòng)作時(shí)間可以不小于10s;長(zhǎng)延時(shí)脫扣器只能作過載保護(hù)。
(2)短延時(shí)脫扣器的電流整定值,動(dòng)作時(shí)間約為0.1~0.4s;短延時(shí)脫扣器可以作短路保護(hù),也可以作過載保護(hù)。
(3)瞬時(shí)脫扣器的電流整定值,其動(dòng)作時(shí)間約為0.02s。瞬時(shí)脫扣器一般用作短路保護(hù)。
10.5 低壓斷路器
(3)瞬時(shí)過電流脫扣器的整定電流
瞬時(shí)脫扣器的動(dòng)作時(shí)間為0.02s左右。
瞬時(shí)或短時(shí)過電流脫扣器的整定電流應(yīng)能躲開線路的尖峰電流。
1)負(fù)載是單臺(tái)電動(dòng)機(jī),整定電流按下式計(jì)算
