电(dian)(dian)(dian)流(liu)(liu)(liu)互(hu)感器铭牌上标(biao)有热(re)稳(wen)定(ding)(ding)(ding)和(he)(he)动稳(wen)定(ding)(ding)(ding)，热(re)稳(wen)定(ding)(ding)(ding)和(he)(he)动稳(wen)定(ding)(ding)(ding)是(shi)(shi)指当系统(tong)发(fa)生短路(lu)时，电(dian)(dian)(dian)流(liu)(liu)(liu)互(hu)感器所能承(cheng)受因短路(lu)电(dian)(dian)(dian)流(liu)(liu)(liu)引起(qi)的(de)热(re)及电(dian)(dian)(dian)动力(li)作用(yong)而不致受到损坏(huai)的(de)能力(li)。电(dian)(dian)(dian)流(liu)(liu)(liu)互(hu)感器的(de)热(re)稳(wen)定(ding)(ding)(ding)和(he)(he)动稳(wen)定(ding)(ding)(ding)，用(yong)热(re)稳(wen)定(ding)(ding)(ding)倍(bei)数(shu)(shu)和(he)(he)电(dian)(dian)(dian)动力(li)稳(wen)定(ding)(ding)(ding)倍(bei)数(shu)(shu)表示。热(re)稳(wen)定(ding)(ding)(ding)倍(bei)数(shu)(shu)为热(re)稳(wen)定(ding)(ding)(ding)电(dian)(dian)(dian)流(liu)(liu)(liu)与互(hu)感器额(e)(e)定(ding)(ding)(ding)电(dian)(dian)(dian)流(liu)(liu)(liu)之比（而热(re)稳(wen)定(ding)(ding)(ding)电(dian)(dian)(dian)流(liu)(liu)(liu)是(shi)(shi)指在(zai)1s内不致使电(dian)(dian)(dian)流(liu)(liu)(liu)互(hu)感器的(de)发(fa)热(re)超(chao)过(guo)允许限(xian)定(ding)(ding)(ding)电(dian)(dian)(dian)流(liu)(liu)(liu)）；电(dian)(dian)(dian)动力(li)稳(wen)定(ding)(ding)(ding)倍(bei)数(shu)(shu)是(shi)(shi)互(hu)感器所能承(cheng)受的(de)最大(da)电(dian)(dian)(dian)流(liu)(liu)(liu)瞬间值与该互(hu)感器额(e)(e)定(ding)(ding)(ding)电(dian)(dian)(dian)流(liu)(liu)(liu)幅值之比。例如(ru)，电(dian)(dian)(dian)流(liu)(liu)(liu)互(hu)感器电(dian)(dian)(dian)压(ya)为10，变比(bi)200/5时，1s热稳(wen)定(ding)15倍(bei)，动稳(wen)定(ding)165倍(bei)。
