請教各位師傅，同一型號，品牌的數控機床，電源供電三相五線(xiàn)，漏保經(jīng)過(guò)三相線(xiàn)+零線(xiàn)。接到數控機床為三相電源+地線(xiàn)（沒(méi)有零線(xiàn)），將地線(xiàn)接在數控機床的PE端。一臺機床不會(huì )跳漏保，另外一臺，合閘就跳漏保，（將變頻器的PE線(xiàn)拆下，送電不跳閘，然后再接回PE線(xiàn)也不跳閘，接PE線(xiàn)時(shí)有跳火的現象），什么原因？有些說(shuō)數控機床不能接漏保，是不是��？

N和PE不能混用
一般不建議數控車(chē)電源經(jīng)過(guò)漏電保護，但要保證可靠的接地
