2、，將漆包線安裝在漆包線電阻測量專用設(shè)備上，用QJ-44 直流電阻電橋測量其電阻值，其測量結(jié)果應(yīng)附合表1漆包線進廠驗收標(biāo)準(zhǔn)參數(shù)表的要求；6.4耐電壓試驗：按照QDS-15KW漆包線電壓試驗儀操作規(guī)程的操作要求對漆包線進行耐電壓試驗，其測量結(jié)果應(yīng)附合表1漆包線進廠驗收標(biāo)準(zhǔn)參數(shù)表的要求；6.5 剝離試驗(適用于導(dǎo)體標(biāo)稱直徑1.000mm以上)：取長度約600mm的試樣一根，將試樣固定于扭絞儀的兩端，夾具之間的試樣長度為500mm，在固定夾具上掛上砝碼，使試樣受到張力。用刮刀將試樣對稱的兩個側(cè)面上的漆膜刮去露出導(dǎo)體，施加在刮刀的壓力應(yīng)能使試樣漆膜刮除，得到一個清潔、光滑的表面，而又不宜刮去過多的導(dǎo)體，

3、距離兩端夾具10mm處的漆膜不應(yīng)刮去。轉(zhuǎn)動儀器，按每分鐘60100轉(zhuǎn)的速度扭轉(zhuǎn)試樣，直到規(guī)定的轉(zhuǎn)數(shù)。轉(zhuǎn)數(shù)按下式求得： R=K/d 式中R試樣扭絞數(shù)，取整數(shù)； d試樣標(biāo)稱直徑， mm； K常數(shù)，B級取130mm， F 級取 150mm。按下表中規(guī)定校正試樣上的砝碼標(biāo)稱直徑(mm)砝碼N 1KG10N1.00d1.4025 N1.40d1.8040 N1.80d2.2460 N試樣經(jīng)受根據(jù)導(dǎo)體標(biāo)稱直徑d計算的轉(zhuǎn)數(shù)R扭轉(zhuǎn)后，漆層應(yīng)不失去附著性，若漆層脫離金屬導(dǎo)線，則判定試樣不合格。*編號：*漆包線進廠檢驗規(guī)范第2頁 共2頁版 次：1修改次：06.6針孔試驗6.6.1配置溶液及接線： A：配置鹽水溶液
