Dianci bileiqi, 2008 对±800kV瓷芯支柱复合绝缘子用硅橡胶进行了研究,为保证硅橡胶在注射硫化过程中与瓷芯棒粘接牢固,且不能产生气隙,选用110-2甲基乙烯基硅橡胶,分子量为630000～650 000。不同配方硅橡胶与瓷芯棒的粘接强度、耐漏电起痕和电蚀损性能对比试验结果表明:在配方中添加少量的复合阻燃剂,可以使硅橡胶护套伞裙材料的直流电压下耐漏电起痕和电蚀损性达到1A4.5级。确定了硅橡胶的混炼工艺和配合体系以及粘接剂的制备方法,并对瓷芯棒与硅橡胶的粘合进行了对比实验,确定了粘合工艺和硫化工艺 ...

Dianci bileiqi, 2014 阐述复合绝缘子压接的工艺过程:当金具和芯棒之间静摩擦力达到1.51.6倍的绝缘子MSL机械拉脱负荷时,这种压接连接认为是可靠的。指出压接关键技术要点:金具与芯棒接触表面处理;绝缘子强度等级和压接力大小的确定。分析了影响压接质量可靠性的因素:金具材质硬度、芯棒弹性模量。为提高复合绝缘子压接组件性能一致性和产品稳定性,应注重金具压接区布置,确定压接段数,选择合适的压接机。

Guangtongxin yanjiu, 1981 本文从几何光学出发,导出由前向散射图决定预制棒的芯、包半径比的公式。对预制棒样件进行了实测,并与其它方法进行对比。前向散射图还可用来定性检查预制棒的质量。
