電纜擊穿試驗

    電纜擊穿試驗

    電(dian)纜(lan)的(de)擊(ji)穿(chuan)試(shi)驗(yan)是(shi)逐(zhu)級(ji)升(sheng)電(dian)壓(ya)直(zhi)至(zhi)絕(jue)緣(yuan)擊(ji)穿(chuan)，求(qiu)得(de)電(dian)纜(lan)的(de)擊(ji)穿(chuan)電(dian)壓(ya)值(zhi)。這(zhe)類(lei)試(shi)驗(yan)的(de)目(mu)的(de)是(shi)考(kao)核(he)電(dian)纜(lan)絕(jue)緣(yuan)承(cheng)受(shou)電(dian)壓(ya)的(de)能(neng)力(li)與(yu)工(gong)電(dian)壓(ya)之(zhi)間(jian)的(de)安(an)全(quan)裕(yu)度(du)。交(jiao)流(liu)擊(ji)穿(chuan)電(dian)場(chang)強(qiang)度(du)是(shi)電(dian)纜(lan)設(she)計(ji)重(zhong)要(yao)參(can)數(shu)之(zhi)一(yi)。
