長(zhǎng)延時(shí)過(guò)電流脫扣器整定電流應(yīng)大于線路中計(jì)算電流
（4-10-9）
式中 ——過(guò)電流脫扣器的長(zhǎng)延時(shí)動(dòng)作整定電
流值，A；
——可靠系數(shù)，一般取1.1；
——線路的計(jì)算電流，單臺(tái)電動(dòng)機(jī)是指
電動(dòng)機(jī)的額定電流，A。
10.5 低壓斷路器
校驗(yàn)一：長(zhǎng)延時(shí)過(guò)電流脫扣器在配電線路過(guò)載時(shí)的可靠性。如對(duì)電動(dòng)機(jī)進(jìn)行保護(hù)，則電動(dòng)機(jī)在過(guò)載 20％時(shí)應(yīng)使保護(hù)裝置動(dòng)作；
校驗(yàn)二：在配電線路出現(xiàn)尖峰負(fù)荷時(shí)或在電動(dòng)機(jī)起動(dòng)時(shí)，長(zhǎng)延時(shí)過(guò)電流脫扣器不誤動(dòng)。脫扣器在3倍整定電流值下的可返回時(shí)間，取決于線路中尖峰電流的持續(xù)時(shí)間，也就是線路中大容量的異步電動(dòng)機(jī)直接起動(dòng)的持續(xù)時(shí)間。
一般情況下，電動(dòng)機(jī)的輕載起動(dòng)時(shí)間不超過(guò)2.5～4s，電動(dòng)機(jī)滿載起動(dòng)時(shí)間不超過(guò)6～8s，個(gè)別電動(dòng)機(jī)重載起動(dòng)時(shí)間達(dá)15s。返回時(shí)間越小，說(shuō)明線路電流大于長(zhǎng)延時(shí)脫扣器整定電流值的倍數(shù)越高，保護(hù)裝置的動(dòng)作越快。
