引起開(kāi)關(guān)柜弧光短路故障的原因很多，主要有：絕緣故障，孝感弧光保護(hù)設(shè)計(jì)廠家、載流回路不良、外來(lái)物體的進(jìn)入、人為操作錯(cuò)誤，孝感弧光保護(hù)設(shè)計(jì)廠家、系統(tǒng)改變或故障等。 </p> <p> 1.2 電弧光的能量 </p> <p> 開(kāi)關(guān)柜發(fā)生內(nèi)部弧光故障產(chǎn)生的短路功率可高達(dá)8~60 MW，所產(chǎn)生的能量與電弧的燃燒時(shí)間、短路電流的平方值、柜體幾何尺寸以及所使用的材料等因素有關(guān)，其中**主要的因素是短路故障電流及電弧燃燒的時(shí)間，電弧能量與有關(guān)電弧燃燒的時(shí)間的關(guān)系如圖所示。從圖中可以看出，電弧燃燒持續(xù)時(shí)間超過(guò)100 ms
