簡便(bian)的做法(fa)(fa)是用兩種不同的電(dian)極材料或兩種不同的使用方法(fa)(fa)來(lai)了解(jie)電(dian)極材料是否會引(yin)入很大 誤差

試樣(yang)的處理條(tiao)件取決于被試材料,這(zhe)些條(tiao)件應在(zai)材料規范(fan)中規定。

推薦按GB/T 10580-2003進(jin)行條件處理;由各種(zhong)鹽溶液所產生的相對濕(shi)度在IEC 60260中給(gei)出。 可以采用機械蒸發系統。

體(ti)積(ji)電(dian)阻(zu)(zu)率和(he)表面(mian)電(dian)阻(zu)(zu)率都對溫度(du)變化特別敏感。這種變化是(shi)指數(shu)式(shi)的(de)。因此(ci)必須在(zai)規定的(de)條件 下來測量試樣的(de)體(ti)積(ji)電(dian)阻(zu)(zu)和(he)表面(mian)電(dian)阻(zu)(zu)。由于水(shui)分被(bei)吸(xi)收到電(dian)介質內(nei)是(shi)相對緩慢的(de)過程,因此(ci)測定濕(shi)度(du) 對體(ti)積(ji)電(dian)阻(zu)(zu)率的(de)影響需(xu)要(yao)延長(chang)處理(li)期。吸(xi)收水(shui)分后通常會降低(di)體(ti)積(ji)電(dian)阻(zu)(zu)。有些(xie)試樣可(ke)能(neng)需(xu)要(yao)處理(li)數(shu)月 才能(neng)達(da)到平衡。

體積電(dian)(dian)(dian)(dian)(dian)阻(zu)在測試(shi)(shi)以前應(ying)使試(shi)(shi)樣(yang)具(ju)有電(dian)(dian)(dian)(dian)(dian)介質穩定(ding)狀態。為此(ci)(ci),通過測量裝(zhuang)置將試(shi)(shi)樣(yang)的(de)(de)(de)(de)測量電(dian)(dian)(dian)(dian)(dian)極1和3短(duan)路(lu) (圖(tu)la)),逐步(bu)增加電(dian)(dian)(dian)(dian)(dian)流測量裝(zhuang)置的(de)(de)(de)(de)靈敏(min)度到(dao)(dao)符合要(yao)求(qiu),同時(shi)觀察短(duan)路(lu)電(dian)(dian)(dian)(dian)(dian)流的(de)(de)(de)(de)變(bian)(bian)化,如此(ci)(ci)繼續到(dao)(dao)短(duan)路(lu)電(dian)(dian)(dian)(dian)(dian) 流達到(dao)(dao)相當恒定(ding)的(de)(de)(de)(de)值(zhi)(zhi)(zhi)為止,此(ci)(ci)值(zhi)(zhi)(zhi)應(ying)小于(yu)電(dian)(dian)(dian)(dian)(dian)化電(dian)(dian)(dian)(dian)(dian)流的(de)(de)(de)(de)穩定(ding)值(zhi)(zhi)(zhi),或者小于(yu)電(dian)(dian)(dian)(dian)(dian)化100 min的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)流。由于(yu)短(duan)路(lu)電(dian)(dian)(dian)(dian)(dian) 流有可能改變(bian)(bian)方向,因此(ci)(ci)即使電(dian)(dian)(dian)(dian)(dian)流為零,也要(yao)維持短(duan)路(lu)狀態到(dao)(dao)需要(yao)的(de)(de)(de)(de)時(shi)間。當短(duan)路(lu)電(dian)(dian)(dian)(dian)(dian)流L變(bian)(bian)得基本恒 定(ding)時(shi)(可能需要(yao)幾小時(shi)),記下L的(de)(de)(de)(de)值(zhi)(zhi)(zhi)和方向。

然后加上(shang)規(gui)定(ding)的(de)直流電(dian)壓并同(tong)時(shi)開始(shi)記(ji)時(shi)」除非另有規(gui)定(ding),在如下每(mei)個(ge)電(dian)化時(shi)間作(zuo)一(yi)次測(ce)量(liang): 1 min,2 min.5 min.10 min.50 min JOO mino如果兩次連(lian)續測(ce)量(liang)得出同(tong)樣的(de)結果,貝lj可以結束試驗并 用這個(ge)電(dian)流值(zhi)來計算體(ti)積電(dian)阻。記(ji)錄第一(yi)次觀察到(dao)相同(tong)測(ce)量(liang)結果時(shi)的(de)電(dian)化時(shi)間。如果在100 min內不 能(neng)達到(dao)穩定(ding)狀態(tai),則(ze)記(ji)錄體(ti)積電(dian)阻與電(dian)化時(shi)間的(de)函數關系。

作(zuo)為驗收試(shi)驗,按(an)照有(you)關規范(fan)的(de)規定,使用一個固定的(de)電(dian)化時間如(ru)1 min后的(de)電(dian)流(liu)值來計(ji)算體積電(dian) 阻率。
