:商洛2098-DSD-HV030 AB伺服驅(qū)動(dòng)器 羅克韋爾廠家也變壓器中性點(diǎn)接地叫做系統(tǒng)接地，或者叫做工作接地。而且中間也重復(fù)接地，還有末端的再次重復(fù)接地，盡管有較大的電流流過(guò)零線，但零線的電位基本為零。所以，TN-C接地系統(tǒng)允許負(fù)載三相不平衡，且有一定的抵抗能力。到PEN線在用電設(shè)備處首先接到設(shè)備的外殼，然后才引到設(shè)備的零線接線端子。也就是說(shuō)，零線的保護(hù)功能優(yōu)先于零線的中性線功能。另外一個(gè)就是很多人疑問(wèn)的一個(gè)：如果上圖中的零線在系統(tǒng)接地點(diǎn)和用電設(shè)備的保護(hù)接零之間發(fā)生了斷裂，會(huì)怎樣呢？即零線斷裂點(diǎn)前方（靠近系統(tǒng)接地處）為零電位，而零線斷裂點(diǎn)后方（靠近用電設(shè)備處）的電壓可能會(huì)上升。
