项目摘要

Silver and copper migration, under the influence of a dc voltage, have been observed through the surface of a dielectric ceramic(CD) used as high voltage condenser and three kinds of organic insulating materials such as phenolic paper laminate(PL), epoxy resin contained glass fiber(GE) and polyester contained glass fiber(GMP). The test condition was 60゜C and 80% R.H. The dielectric ceramic was applied 250 V dc and the organic Insulating materials were applied 100 V dc.At first, the water content was measured for all materials. The water content of PL was found to be 1.4 % during 100 hours. On the other hand, the dielectric ceramic was found to be below 0.05 %. GE and GMP were about 0.2 %.There was no migration phenomenon for dielectric ceramics. It was found, however, that the silver migration for PL was easily occurred as compared with that for GE and GMP. The surface resistivity for PL was abruptly reduced against the application time of voltage. This is because the paper in PL easily adsorps water.On the other hand, no migration was found for copper electrode even PL during 200 hours.There was found a little migration for PL coated with epoxy resin during 300 hours. It seems that epoxy resin supresses the absorption of water.
研究了高压电容器用介质陶瓷(CD)和三种有机绝缘材料酚醛纸板(PL)、含环氧树脂玻璃纤维(GE)和含聚酯玻璃纤维(GMP)在直流电压作用下银和铜的迁移。试验条件为60゜C、80%相对湿度,介质陶瓷施加250V直流电压,有机绝缘材料施加100V直流电压。在100h内,PL的水分含量为1.4%。另一方面,介电陶瓷的质量分数在0.05%以下。Ge和GMP含量在0.2%左右,介电陶瓷没有迁移现象。然而,与Ge和GMP相比,PL更容易发生银的迁移。随着电压作用时间的延长,发光材料的表面电阻率急剧下降。这是因为光致发光中的纸容易吸附水分。另一方面,铜电极在200小时内没有迁移,即使是光致发光也是如此。在300小时内,环氧树脂包覆的光致发光有少量的迁移。环氧树脂似乎抑制了吸水率。
