**********编号：*********漆包线进厂检验规范第1页共2页版次：1修改次：01、适用范围:本规范适用于本公司漆包线进货检验；2、目的:防止不合格漆包线进厂；3、职责:外协检验员负责；4、检验设备：QDS-15KV漆包线耐压试验仪、QJ-44直流电阻电桥、针孔测试仪、扭绞仪、外径千分尺；5、检验方法：抽检；6、检验规范：6.1抽样标准：每批漆包线进厂时每种规格线径各抽一轮进行检验，如一种规格的漆包线有不同批号、时间生产的应分别抽检；6.2线径测量：用外径千分尺测量漆包线最大外径和漆膜厚度，其测量结果应附合表1《漆包线进厂验收标准参数表》的要求；6.3电阻值测试：取1米漆包线并在线两头刮净绝缘漆膜，将漆包线安装在漆包线电阻测量专用设备上，用QJ-44直流电阻电桥测量其电阻值，其测量结果应附合表1《漆包线进厂验收标准参数表》的要求；6.4耐电压试验：按照《QDS-15KW漆包线电压试验仪操作规程》的操作要求对漆包线进行耐电压试验，其测量结果应附合表1《漆包线进厂验收标准参数表》的要求；6.5剥离试验(适用于导体标称直径1.000mm以上)：取长度约600mm的试样一根，将试样固定于扭绞仪的两端，夹具之间的试样长度为500mm，在固定夹具上挂上砝码，使试样受到张力。用刮刀将试样对称的两个侧面上的漆膜刮去露出导体，施加在刮刀的压力应能使试样漆膜刮除，得到一个清洁、光滑的表面，而又不宜刮去过多的导体，距离两端夹具10mm处的漆膜不应刮去。转动仪器，按每分钟60～100转的速度扭转试样，直到规定的转数。转数按下式求得：R=K/d式中R—试样扭绞数，取整数；d—试样标称直径，mm；K—常数，B级取130mm，F级取150mm。按下表中规定校正试样上的砝码标称直径(mm)砝码N1KG≈10N1.00＜d≤1.4025N1.40＜d≤1.8040N1.80＜d≤2.2460N试样经受根据导体标称直径d计算的转数R扭转后，漆层应不失去附着性，若漆层脱离金属导线，则判定试样不合格。 ************编号：*********漆包线进厂检验规范第2页共2页版次：1修改次：06.6针孔试验6.6.1配置溶液及接线：A：配置盐水溶液：食盐30克，清水10公斤，浓度为3‰；B：配置酚酞溶液：酒精100克，酚酞3克，浓度为3﹪；C：配置溶液：每10公斤盐水溶液加入20毫升酚酞溶液。D：按下图检查盐浴装置电源正负极接线是否正确，导电体接正极直接接入盐浴池，被测漆包线接负极；E：电源正确连接后，通24伏直流电。每次做试验前要检查溶液的导电性能，将“+”和“-”极直接浸入盐水溶液池中，观察电流表的读数，导通电流是否达到标准值500毫安，否则要重新调配溶剂方可试验。6.6.2漏电流及针孔数测试标准：电流法测试标准：线径mm漆包线漏电流mA浸泡时间通电时间＜0.43min3min＜100.4-0.71min1min＜10＞0.7不必浸泡1min＜20针孔数测试标准：如针孔数量少于5个且不在同一个部位30米之内，则可接受；其他情形均不能接受。6.6.3测试方法：A.漆包线测试长度5米； B.将漆包线试样放入盐浴池中，按图接好电源正负极，通直流电24伏，按漏电流接受准则进行测试，如果没有出现红色液体说明漆包线盐浴测试合格；如果有红色液体说明有针孔，仔细观察针孔的数量及损伤部位，并做好记录；C.当电流法超标时，请采用针孔法进行分析；D.要对电流法测试的漏电流数据及针孔法分析的针孔数进行记录，同时对每次换水进行记录。6.6.4操作注意事项：A.盐水浓度比例必须按3‰调配，必须每天更换，并做好记录；B.每次盐浴时必须检查导电性能，将正负极直接浸入盐水中，观察电流表读数必须大于500毫安；C.检验的漆包线（除两个线头外）必须全部沉浸在盐浴池中；D.要保证电源正极有效连接，注意正负极不能接反。6.7经以上试验合格的漆包线方可入库生产，不合格品出具不合格品报告由品管部主管批准后退回协作厂；6.8做好每个检验项目的检验记录和判定结果。`7.相关文件及记录7.1《漆包线进厂线径、电阻值检验表》7.2《漆包线进厂试验记录单》7.3《漆包线扭绞、针孔试验记录单》8、附表1 表1漆包线进厂验收标准参数表(2级)标称直径最大外径极限偏差(±)最小漆膜厚度1米电阻允许击穿最低电压最小(Ω/m)最大(Ω/m)电压(KV)扭绞数(个)0.2000.2390.0030.0270.52370.56593.5330.2100.2520.0030.0290.47570.50363.7330.2200.2620.0030.0290.43400.46623.7330.2300.2770.0040.0320.39410.42983.9330.2500.2970.0040.0320.33450.36283.9330.2700.3190.0040.0330.28750.31034.0230.2900.3420.0040.0350.24970.26844.1230.3100.3620.0040.0350.21890.23444.1230.3300.3860.0040.0380.19340.20664.3230.3500.4060.0040.0380.17220.18344.3230.3550.4110.0040.0380.16740.17824.3230.3800.4390.0050.0400.14560.15614.4160.4000.4590.0050.0400.13160.14074.4160.4100.4730.0050.0420.12530.13384.4160.4200.4830.0050.0420.11950.12754.4160.4250.4880.0050.0420.11670.12444.4160.4400.5030.0050.0420.10900.11604.4160.4500.5130.0050.0420.10420.11094.4160.4700.5360.0050.0450.095650.101504.6160.4900.5560.0050.0450.088070.093324.6160.5000.5660.0050.0450.084620.08964.6160.5100.5800.0060.0470.081050.086424.6120.5300.6000.0060.0470.075120.079954.6120.5500.6200.0060.0470.069810.074184.6120.5600.6300.0060.0470.067360.071534.6120.5700.6440.0060.0500.065040.069014.8120.5900.6640.0060.0500.060750.064374.8120.6000.6740.0060.0500.058760.062224.812 表1续漆包线进厂验收标准参数表(2级)标称直径最大外径极限偏差(±)最小漆膜厚度1米电阻允许击穿最低电压最小(Ω/m)最大(Ω/m)电压(KV)扭绞数(个)0.6200.6940.0060.0500.055070.058234.8120.6300.7040.0060.0500.053350.056384.8120.6400.7190.0070.0530.051550.054794.8120.6500.7290.0070.0530.050000.053104.8120.6700.7490.0070.0530.047080.049944.8120.6900.7690.0070.0530.044420.047064.8120.7100.7890.0070.0530.041980.044204.8120.7200.8040.0080.0560.040720.043304.980.7400.8240.0080.0560.038570.040974.980.7500.8340.0080.0560.037560.039874.980.7700.8540.0080.0560.035650.037814.980.8000.8840.0080.0560.033050.035004.980.8300.9190.0090.0600.030660.032575.080.8500.9390.0090.0600.029250.031055.080.8600.9490.0090.0600.028580.030315.080.9000.9890.0090.0600.026120.027655.080.9301.0240.0100.0630.024420.025945.080.9501.0440.0100.0630.023420.024845.080.9601.0540.0100.0630.022940.024325.081.0001.0940.0100.0630.021160.022405.081.0401.1370.0110.0650.019540.020735.081.0601.1570.0110.0650.018810.019955.081.0801.1770.0110.0650.018130.019215.061.1201.2170.0110.0650.016870.017855.061.1601.2590.0130.0670.015680.016695.061.1801.2790.0130.0670.015160.016125.061.2001.2990.0130.0670.014670.015585.061.2501.3490.0130.0670.013530.014355.06 表1续漆包线进厂验收标准参数表(2级)标称直径最大外径极限偏差(±)最小漆膜厚度1米电阻允许击穿最低电压最小(Ω/m)最大(Ω/m)电压(KV)扭绞数(个)1.3001.4020.0140.0690.012500.013275.061.3201.4220.0140.0690.012130.012875.061.3501.4520.0140.0690.011600.012305.061.4001.5020.0140.0690.010790.011435.061.4501.5560.0160.0710.010040.010685.041.5001.6060.0160.0710.009590.0099685.041.5601.6660.0160.0710.0086880.0092085.041.6001.7060.0160.0710.0082640.0087495.041.6801.7890.0180.0730.0074850.0079475.041.7001.8090.0180.0730.0073120.0077595.041.7401.8490.0180.0730.0069830.0074035.041.8001.9090.0180.0730.0065290.0069135.041.8601.9720.0200.0750.0061060.0064845.041.9002.0120.0200.0750.0058540.0062115.041.9502.0620.0200.0750.0055610.0058935.042.0002.1120.0200.0750.0052890.0055605.042.1202.2350.0220.0770.0047030.0049875.032.2402.3550.0220.0770.0042180.0044625.032.3602.4780.0250.0790.0037940.0040265.032.4402.5580.0250.0790.0035520.0037645.032.5002.6180.0250.0790.0033850.0035845.03对于导体标称直径的中间尺寸，应取下一个较大导体标称直径对应的最小漆膜厚度和最低击穿电压。
