描述
其實(shí),電氣設(shè)備維修人員在檢修電氣設(shè)備和線路時(shí),如果用鉗形電流表檢查故障,也是個(gè)很好的辦法。電氣設(shè)備出現(xiàn)故障時(shí),電流是會(huì)發(fā)生變化的。用電流表來(lái)觀察電流,也可以很快的確定故障。如電動(dòng)機(jī)三相電流過(guò)大,那是過(guò)載;如三相不平衡,有可能是電動(dòng)機(jī)繞組匝間短路的問(wèn)題。對(duì)電氣設(shè)備本身有故障,但又需要通電來(lái)查找故障原因時(shí),通電時(shí)間不能過(guò)長(zhǎng)。比如三相電動(dòng)機(jī)缺相運(yùn)行,通電時(shí)間長(zhǎng)了,是會(huì)燒毀電動(dòng)機(jī)的。
