 1.电介质:又称绝缘资料(liao),简(jian)称绝缘,是电工中利用最(zui)普(pu)遍的资料(liao)之一(yi)。 
    2.绝(jue)缘电阻(zu)(zu):加直流电压于(yu)电介质(zhi),颠末必(bi)然时候极化(hua)进程竣事后,流过电介质(zhi)的泄泄电流对应的电阻(zu)(zu)称绝(jue)缘电阻(zu)(zu)。 
    3.接(jie)收比(bi): 在(zai)统一次(ci)实验中,60s时的(de)绝缘(yuan)电阻值与15s时的(de)绝缘(yuan)电阻值之(zhi)比(bi)。 
    4.极(ji)化指(zhi)数:在统一(yi)次实(shi)验中,10min时的绝缘电阻(zu)值(zhi)与1min时的绝缘电阻(zu)值(zhi)之(zhi)比(bi)。 
    5.介质消耗(hao):在外(wai)加电压感化下,电介质中的一局部电能(neng)被(bei)转换为热能(neng),这类景(jing)象(xiang)称为介质消耗(hao)。 
    6.阻(zu)性电(dian)(dian)(dian)流(liu):有消耗的(de)(de)介质能够用一(yi)个抱(bao)负电(dian)(dian)(dian)容和一(yi)个有用电(dian)(dian)(dian)阻(zu)的(de)(de)并联(lian)电(dian)(dian)(dian)路(lu)表现,经由(you)过(guo)程电(dian)(dian)(dian)阻(zu)的(de)(de)电(dian)(dian)(dian)流(liu)称阻(zu)性电(dian)(dian)(dian)流(liu)。 
    7.容(rong)(rong)性电(dian)流:有消耗的介质能(neng)够用一(yi)个抱负电(dian)容(rong)(rong)和一(yi)个有用电(dian)阻的并联电(dian)路表现(xian),经由过程电(dian)容(rong)(rong)的电(dian)流称容(rong)(rong)性电(dian)流。 
    8.全电(dian)(dian)流:有消(xiao)耗的(de)介质能够(gou)用一(yi)个抱(bao)负电(dian)(dian)容和(he)一(yi)个有用电(dian)(dian)阻(zu)的(de)并联电(dian)(dian)路表(biao)现,经由过程电(dian)(dian)容的(de)容性电(dian)(dian)流与(yu)经由过程电(dian)(dian)阻(zu)的(de)阻(zu)性电(dian)(dian)流的(de)相量和(he)称全电(dian)(dian)流。 
    9.介(jie)质消耗(hao)角:电(dian)介(jie)质中全电(dian)流与电(dian)容(rong)电(dian)流之间的(de)夹角(通经常使用δ表现),称为介(jie)质消耗(hao)角。
    10.在(zai)线丈量(liang):对在(zai)运转(zhuan)电压下的(de)装备,接纳公用仪器,由职(zhi)员到(dao)场停止的(de)丈量(liang)。 
    11.在线监(jian)测(ce):在不影(ying)响(xiang)装(zhuang)备运转的前提下(xia),对(dui)装(zhuang)备状况持续或按时停止(zhi)的监(jian)测(ce),凡是是主动停止(zhi)的。
    12.状(zhuang)况检验:由美(mei)国(guo)通用电气公司(si)等提出(chu)要从以时候为(wei)基(ji)准的(de)检验体(ti)(ti)例成长(zhang)到以装(zhuang)备运转状(zhuang)况为(wei)基(ji)准的(de)检验体(ti)(ti)例。 
    13.防备(bei)性(xing)实验(yan):为了发明运转中装(zhuang)备(bei)的(de)(de)隐患,防备(bei)产生(sheng)变(bian)乱或(huo)装(zhuang)备(bei)破坏,对装(zhuang)备(bei)停止的(de)(de)查抄、实验(yan)或(huo)监(jian)测,也包含取(qu)油样(yang)或(huo)气(qi)样(yang)停止的(de)(de)实验(yan)。 
    14.变(bian)比(bi)(bi):变(bian)压(ya)(ya)(ya)(ya)器(qi)高(gao)压(ya)(ya)(ya)(ya)侧(ce)绕(rao)组(zu)与(yu)高(gao)压(ya)(ya)(ya)(ya)侧(ce)绕(rao)组(zu)匝数(shu)之比(bi)(bi)称(cheng)为变(bian)比(bi)(bi),类似可用(yong)高(gao)压(ya)(ya)(ya)(ya)侧(ce)与(yu)高(gao)压(ya)(ya)(ya)(ya)侧(ce)额外电(dian)压(ya)(ya)(ya)(ya)之比(bi)(bi)表现(xian)。 
    15.伏(fu)安特征:加(jia)在电气(qi)装备(bei)或(huo)元(yuan)件两头电压(ya)和经由过程电流的干系叫伏(fu)安特征。
