簡便的做法是用兩種(zhong)(zhong)不同(tong)(tong)的電極材料或兩種(zhong)(zhong)不同(tong)(tong)的使用方法來了解(jie)電極材料是否會引入很大(da) 誤差

試樣的處理條(tiao)件取決于被試材料,這些條(tiao)件應(ying)在材料規(gui)范中(zhong)規(gui)定。

推薦按(an)GB/T 10580-2003進行條件處理;由(you)各(ge)種鹽(yan)溶液所產生的相對(dui)濕(shi)度(du)在IEC 60260中給出(chu)。 可以采用機械蒸發系統。

體積(ji)電(dian)(dian)阻(zu)率(lv)和表(biao)面(mian)電(dian)(dian)阻(zu)率(lv)都(dou)對溫度(du)變(bian)化特別敏感。這種變(bian)化是(shi)指數式的。因(yin)此(ci)必須在規定的條件 下(xia)來(lai)測(ce)量試樣(yang)的體積(ji)電(dian)(dian)阻(zu)和表(biao)面(mian)電(dian)(dian)阻(zu)。由于水(shui)分(fen)被吸收到電(dian)(dian)介(jie)質內是(shi)相對緩慢(man)的過程(cheng),因(yin)此(ci)測(ce)定濕度(du) 對體積(ji)電(dian)(dian)阻(zu)率(lv)的影響(xiang)需要延長處理期。吸收水(shui)分(fen)后通常會降低體積(ji)電(dian)(dian)阻(zu)。有些試樣(yang)可(ke)能需要處理數月 才能達到平(ping)衡。

體積電阻(zu)在(zai)測(ce)(ce)(ce)試(shi)以前應使(shi)試(shi)樣具有(you)電介質(zhi)穩(wen)定(ding)狀態。為此,通(tong)過測(ce)(ce)(ce)量裝置(zhi)將試(shi)樣的(de)(de)測(ce)(ce)(ce)量電極1和3短(duan)路(lu) (圖la)),逐步增加電流(liu)測(ce)(ce)(ce)量裝置(zhi)的(de)(de)靈敏度到(dao)(dao)符合要(yao)求,同時(shi)(shi)觀(guan)察短(duan)路(lu)電流(liu)的(de)(de)變化,如(ru)此繼(ji)續到(dao)(dao)短(duan)路(lu)電 流(liu)達到(dao)(dao)相當(dang)恒(heng)定(ding)的(de)(de)值(zhi)(zhi)為止,此值(zhi)(zhi)應小(xiao)(xiao)于電化電流(liu)的(de)(de)穩(wen)定(ding)值(zhi)(zhi),或者(zhe)小(xiao)(xiao)于電化100 min的(de)(de)電流(liu)。由于短(duan)路(lu)電 流(liu)有(you)可能改變方向,因此即使(shi)電流(liu)為零,也要(yao)維持短(duan)路(lu)狀態到(dao)(dao)需(xu)要(yao)的(de)(de)時(shi)(shi)間。當(dang)短(duan)路(lu)電流(liu)L變得基本恒(heng) 定(ding)時(shi)(shi)(可能需(xu)要(yao)幾小(xiao)(xiao)時(shi)(shi)),記下L的(de)(de)值(zhi)(zhi)和方向。

然后加上規定(ding)的直流電(dian)(dian)壓并同(tong)時開始記(ji)時」除非另有規定(ding),在如下每(mei)個電(dian)(dian)化時間(jian)作一次(ci)測(ce)量(liang): 1 min,2 min.5 min.10 min.50 min JOO mino如果(guo)(guo)兩次(ci)連續(xu)測(ce)量(liang)得出同(tong)樣的結(jie)(jie)果(guo)(guo),貝lj可以結(jie)(jie)束試驗并 用這(zhe)個電(dian)(dian)流值來計算(suan)體積電(dian)(dian)阻(zu)。記(ji)錄(lu)第(di)一次(ci)觀察到相同(tong)測(ce)量(liang)結(jie)(jie)果(guo)(guo)時的電(dian)(dian)化時間(jian)。如果(guo)(guo)在100 min內不 能達到穩定(ding)狀態,則(ze)記(ji)錄(lu)體積電(dian)(dian)阻(zu)與電(dian)(dian)化時間(jian)的函數關系(xi)。

作為驗收試驗,按照有(you)關規(gui)范的規(gui)定(ding)(ding),使用一個固(gu)定(ding)(ding)的電化時間如1 min后的電流值來(lai)計算體積電 阻率(lv)。
